Universal laptop charger
Sometimes you need to charge the batteries of various devices, but there is no suitable charging, a universal battery charger will come to the rescue. The scheme of its operation is quite simple and compatible with almost any device. The universal charger has the following operating scheme.
Schematic representation of an electric universal charger
For different types of batteries, it is enough just to change the charge current. It should be 0.1 A of the battery capacity, then with such a charge, the battery will last for about 800 charge / discharge cycles, depending on the type of battery. The charging time, taking into account the current 0.1 A from the battery capacity, will be 10-12 hours.
Acid batteries need to be charged with a choice of discharge 10 times less than other devices. This is done using the S2 and S3 toggle switches available on the adapter, where the current strength is 0.1 and 0.25 A, respectively. If both levers are connected, then the value is set to 0.35 A. It follows that the acid battery must be charged under the action of a current of 1, 2.5 and 3.5 A.
Specifications for universal battery charger
NOTE!
It is better to connect a multifunctional charger from a 220 V network, provided that grounding is installed or a voltage stabilizer is installed. Otherwise, you risk getting a failed battery and broken charging due to a voltage failure.
Universal charger for all types of batteries: technical features
The choice of the adapter is based on the technical characteristics
What parameters are best to consider when choosing a universal charger.
| Parameter | Description |
| Type of batteries and accumulators | The device can be combined (when it is acceptable to use different types of batteries, including finger-type) or standard, which is designed for one carrier. It often charges AA or AAA-type rechargeable batteries, as well as mobile, crown, laptop (if there is a USB port) and others. |
| Current strength | This parameter can be changed manually, depending on the battery requirements. However, the higher the parameter, the faster the battery will charge. It is noted that online charging will shorten battery life. |
| Number of charging channels | The more outputs for various installations, the more multifunctional the device is considered. It happens that purchased models have channels with different amperage. |
| Availability of additional features: | Discharge: In the vast majority of cases, batteries are difficult to discharge to the minimum before charging. This function in the adapter is very convenient, as it allows you to completely discharge the battery. Display: The screen displays all the characteristics of the flowing charge, including amperage, voltage and operating time. Overheating and error protection: In case of power surges, the device will help to avoid damage to the battery, as it stabilizes the charge channel. The function is also able to prevent the battery from burning out if it is installed in the wrong polarity. |
| Saving function | You've probably heard about the Boost mode in the charger. What it is, every electronics knows. This is a function that, after a full battery charge, turns itself off, saving energy and preventing the battery from burning out. At the same time, it charges the battery for a certain time. |
Some types of adapters are capable of operating from an unconventional 12V network. This installation is practical, since it can be carried with you and even connected to a car cigarette lighter.
IMPORTANT!
To keep the battery in good condition, charge it fully for 14 to 16 hours once every few weeks, at least once a quarter.
If you do not have the opportunity to periodically charge the battery for such a long time, then try to use the battery at a moderate temperature and avoid deep discharges.
How to choose a universal battery charger: expert advice
If you are faced with an acute question of choosing a charging for a battery, you need to decide exactly where it will be used. In addition, pay attention to the following points:
- manufacturer and its relevance. The more well-known the brand of charging, the lower the likelihood of falling victim to counterfeiting. Today on the market you can find installations from UFO, Sony, Samsung, Varta and others. These models are popular thanks to user reviews;
- the integrity of the packaging and the performance of the adapter. When choosing, be sure to make sure that the device is not opened before you. The buyer must independently verify this, check the device for operability in the store;
A large number of ports is a significant advantage for universal charging
- nominal capacity of the installation. It is important that this parameter meets your requirements. 2000-10,000 mAh is enough to charge mobile devices, and a laptop and other equipment will require a large capacity;
- charging power - this is an equally important parameter when choosing. Allowable battery charge current - 10% of its capacity;
- availability of USB port... This feature is now quite comfortable, as it allows you to charge traditional home electronics;
- be sure to decide on the type of adapter: can be portable, impulse and passive. The latter is ideal for cases where it is necessary to convert current for high-quality and safe battery charging;
- choose a suitable charging scheme for the installation. There are options that operate with constant current and those that operate with constant voltage. The first type does not guarantee a safe charge, since it does not protect against overheating, and the second is unable to fully charge the battery. Accordingly, the combination adapter should be selected.
What is Boost mode in a charger: how it works
Almost any charger with multiple functions has a quick charge (BOOST) mode. Such a function can help out if there is no time for deep charging. For example, if during an important call your phone runs out of power and it takes at least 30 minutes to turn it on. In such a situation, it is better to use the BOOST mode, it will help reanimate the residual battery charge for a while.
Fast charging negatively affects battery life

Universal charger "Frog" for phones - overview
A compact charger called "Frog" has been serving people for many years. Its advantages are compactness and versatility. With it, you can charge the battery from a mobile phone of any model, you just need to properly push the antennae of the device.
"Frog", "Clothespin" for the phone will fit all types of mobile gadgets
The device is made in China, has several indicators that show the beginning of the charge in red (second indicator), when the charge ends, the green indicator lights up (third light). The gadget is able to independently determine the polarity of the connected battery, so you don't have to worry about whether you installed it correctly. "Toad" is suitable only for batteries with a capacity of not more than 2000 mAh at alternating current up to 200 mA. Charging on this device lasts more than 1.5 hours. You can buy a universal charger "Frog" both in online stores and in any radio kiosk.
But buying online can be frustrating. Read product reviews carefully and do not forget to require certificates. On average, buying a battery charger for cars will cost from 900 to 3,000 rubles. The price depends on the feature set and the manufacturer's brand. A universal charger for smartphones can be purchased at a price of 250-500 rubles, a charger for a laptop can be purchased for 900-2,500 rubles.
If you purchased such devices, share your opinions in the comments to the article. Let's understand together the peculiarities of the functioning of devices and their advantages for a modern person.
A considerable number of all kinds of household appliances and electronics run on various types of batteries. Among the gadgets where their use is most in demand, there are cameras, repair tools (drills, screwdrivers, etc.), flashlights, sound recording equipment, and much more. Theoretically, all of the above equipment can be powered by conventional AA and AAA batteries (provided that the devices are compatible with them), which are sold in literally every store (Durasells, Energizers, etc.). But in practice, in most cases, this is simply unprofitable, since they sit down very quickly. It is more advisable to use rechargeable batteries (out of habit, they are also often called batteries). When properly charged, they can work from 200 to 500 cycles (depending on the type and quality). But for the full operation of such batteries, you must have a special charger (charger). It is worth choosing this device based on the tasks that will be assigned to it. The most important are the following characteristics:
- A type... There are three main types of charger: simple (very cheap, but without the auto-off function), automatic (turns off when the battery reaches a full charge) and intelligent (a lot of additional features, we will consider them below).
- Compatibility... Each battery has characteristics such as size (AA, AAA, 18650, Crohn, etc.) and electrochemical system (Ni-Cd, Ni-Mh, Li-Ion, and others). Therefore, first you need to determine which batteries you need a charger for, and then look for a device that is suitable for working with them.
- Number of connectors... Somewhere 1-2 slots will be enough, but in other situations it is important to simultaneously install as many batteries as possible.
- Current strength... Weak current (0.1 A) is the safest and is considered recommended, but the process of fully charging it takes a very long time (14-16 hours). A correspondingly high current will save time, but reduce the overall battery life.
We have collected for you the TOP 10 best chargers from the Aliexpress website. When choosing products, the main focus was on indicators such as:
- functionality and characteristics of the device;
- user reviews;
- value for money;
- seller reliability rating.
Best budget chargers with Aliexpress
3 PALO C824
Lowest price tag for AA batteries
Price for Aliexpress: from 122 rubles.
Rating (2019): 4.8
The most basic device of this type. Compatible with so-called AA and AAA (Ni-MH / Ni-Cd) rechargeable batteries. At the same time, there are no interesting possibilities here, in principle, not to mention the screen. And since the charger does not automatically turn off after the battery is fully charged (that is, up to an explosion), you need to carefully monitor the process yourself (i.e. manually calculate the approximate time required based on the battery capacity and the PALO C824 standard current of 150-160 mAh) ... The device has an LED indicator, but there is no particular sense from it - it only indicates whether the battery is charging or not without any information about the progress of the process.
2 JETTING USB Battery Charger
Best price
Price for Aliexpress: from 69 rubles.
Rating (2019): 4.8
A simple device that includes only a compact plastic case (the USB cable will have to be taken out separately). Suitable for charging batteries of the 18650 form factor (the older model will also master 26650 batteries), and from the proposed functionality there is only light indication of the charging status (red lights turn green) and automatic shutdown when a full charge is reached (set current limit - 1A) ...
In general, Jetting more than copes with its task; among the large number of reviews, there are practically no complaints about any problems with the technical side and performance. However, you should be prepared for the fact that the delivery to the Russian Federation from the seller, although free, is very long.
1 VariCore 04U
Affordable price for 4-slot charger
Price for Aliexpress: from 330 rubles.
Rating (2019): 4.9
A very budgetary, but at the same time quite versatile gadget, which has 4 connectors for batteries at once. Despite the fact that the manufacturer recommended a device for recharging 3.7 V batteries (models from 10440 to 18650), VariCore can also charge other types of batteries (AA and AAA), however, in this case, the indicators will not inform you about the end of this operation, therefore you will have to take care of everything yourself.
According to the manufacturer, the device provides as many as six types of protection (against overload, overheating, short circuit, full discharge, etc.), but users do not recommend inserting more than 3 batteries into it at the same time. The speed of the process depends entirely on the power supply to which the USB cable is connected.
The best chargers for everyday use with Aliexpress
If there are not a lot of equipment at home that requires batteries for their work, or these devices are used quite rarely, then there is little point in overpaying significantly for a memory with a huge number of slots and a bunch of additional functions. In this case, simpler and more compact models are quite suitable.
4 VONTAR Single Charger
Optimal choice for Li-Ion batteries
Price for Aliexpress: from 525 rubles.
Rating (2019): 4.8
Single Charger from VONTAR is perfect for 3.7 V lithium-ion batteries (sizes 26650, 18650, 18500, etc.). The gadget is equipped with a small display, which displays information about the voltage, percentage of charge and the current used (two options are available: 0.5 A and 1 A). After the battery inserted in the charger is fully charged, the device automatically stops this process, which allows the batteries to be used at maximum efficiency. The external output of the device is a Micro USB port, so an additional network adapter is required for operation (you can take it from almost any Android phone at 5V / 1A). The disadvantage of Single Charger is only a narrow range of compatibility for its price (as mentioned above, it only works with a 3.7V battery).
3 PALO C905W
Intuitive interface
Price for Aliexpress: from 599 rubles.
Rating (2019): 4.8
Despite the fact that the C905W has four free slots at once, the memory itself is very compact and simple (even those who first encounter such equipment can easily figure it out). This model is compatible with AA and AAA (Ni-MH / Ni-Cd) batteries and is able to automatically shut down when a full charge is reached. There is also a screen, but it almost does not perform any functions, but simply serves as a kind of progress indicator (and the information is given not in percentages, but in divisions - this is not always convenient). Of the advantages, one can also note direct operation from the network (you will not have to look for adapters), and the main disadvantage is the inability to choose the desired current strength yourself (by default it gives out 1.2 A, which is sometimes too much). In addition, when simultaneously charging 4 batteries at once, the C905W heats up, albeit slightly.
2 LiitoKala Lii-100
Compact and convenient
Price for Aliexpress: from 354 rubles.
Rating (2019): 4.9
LiitoKala is one of the largest and most famous companies in the battery charger market. They offer a wide selection of storage devices to suit every taste and budget. For example, the considered model Lii-100 has a number of advantages at a low price. Among them, there is good compatibility with almost all popular types of batteries (Li-Ion, Ni-MH, Ni-Cd), and a smart control system (automatically detects the type of inserted battery, independently starts and ends charging, and also detects defective and discharged devices) , and the presence of a mini-display with indicators (displays the current progress). Separately, it should be noted the presence of a USB output on the case, which allows you to use the memory as a power bank. Of course, one battery slot is unlikely to last long, but, on the other hand, charging smartphones is still not the main function of the Lii-100. As with the VONTAR Single Charger, the mains adapter is not included.
1 LiitoKala Lii-202
The best ratio of price and quality
Price for Aliexpress: from 674 rubles.
Rating (2019): 5.0
Lii-202 is a two-slot charger from LiitoKala. In terms of basic parameters, this version is almost no different from the Lii-100, but there is nothing wrong with that, since it already has everything that is necessary for optimal operation: wide compatibility with various batteries (from AAA to 18650), LED indicators of charge progress and the ability to switch the current. However, Lii-202 is much more convenient to use as a power bank, since there are several battery connectors. A significant plus is also the fact that the network adapter (5V / 1A) is included in the package - you don't have to look for anything else.
Best professional battery chargers with Aliexpress
The term "professional" in the name of the category is rather arbitrary, we are talking about those situations when a person constantly deals (mainly at work) with many batteries and he needs a charger that can simultaneously charge them in the required amount.
3 PALO P10
Favorable price for a memory with 8 slots
Price for Aliexpress: from 491 rubles.
Rating (2019): 4.8
The undoubted advantage of this gadget is the number of connectors for batteries - there are as many as 8. This should be enough for even the most demanding customers. The rest of the design is very simple - there are no serious functions and even a small display here. Of the stated capabilities - smart control (automatic shutdown when 100% is reached) and LED indicators that offer the user information about the current status of the charger. Relative disadvantages include the multiplicity of the charging process (at the same time you need to insert 2,4,6 or 8 batteries, that is, an even number) and the impossibility of independent selection of the current used. PALO P10 is only compatible with AA or AAA type devices (Ni-MH, Ni-Cd).
2 LiitoKala Lii-500
Wide range of functions
Price for Aliexpress: from 1214 rubles.
Rating (2019): 4.9
Lii-500 is the older model from the LiitoKala brand memory line. Accordingly, her functionality is the richest among all her brothers. First of all, it is necessary to note the many available operating modes: standard, quick test (charge-discharge cycle followed by capacity measurement), full test (a similar procedure, but it takes more time and the result is more accurate), determination of battery health. Instead of single indicators, a much more informative screen is installed in this charger, and 4 types of current of different power are available for charging at once. Like other gadgets from Liitokala, thanks to the USB output, the Lii-500 can be used as a power bank, but given the dimensions of the device, it will not be very convenient and expedient. In addition to the external power supply, the kit also includes a cable for connecting to the cigarette lighter in the car and detailed instructions in English.
1 Opus BT-C3100
The most powerful
Price for Aliexpress: from 2060 rubles.
Rating (2019): 5.0
Opus is LiitoKala's main competitor in the battery charger market. And BT-C3100 is the most expensive and functional product in their line of storage devices. In this regard, when discussing the merits and capabilities of this model, all this happens in the context of comparison with the rival flagship Lii-500. Among those, it is necessary to highlight a greater number of operating modes (three previously mentioned plus "battery discharge"), a wide power range (you can set any current from 200 to 2000 mA), the presence of an active cooling system (fan). In addition, many users wrote in their reviews that the BT-C3100 is almost the only charger that is capable of efficiently restoring "dead" batteries.
Every motorist sooner or later finds himself in a situation where the car battery is discharged. And this becomes an obstacle to starting the engine. Most often this happens in the winter season, since at low temperatures the battery holds a charge very poorly and quickly discharges even when idle. Let's imagine a situation: you left your car on the street at minus ten degrees Celsius and returned in a week. What will happen? The battery is definitely discharged. And here one of two things remains: to "light" it from another car, which will have to be stopped, or to charge it using a special device. Such a device is a universal
1. How to choose a universal battery charger.
The question "How to choose a universal charger?" sales consultants in car stores hear every day. And this is understandable, because every day it will take from some motorist, and the battery will be discharged. And you have to do something about it. So upset drivers run to the store, trying to get their car back on track. And to save money, they buy a charger instead of a new battery. Charging a battery, like a quality battery, is the right investment. I bought it once and have been using it for many years. There are two types of chargers:
1. For a specific model and type of battery.
2. Universal chargers.
Most chargers are universal and will fit almost all batteries. There are, of course, their own nuances in the choice of universal chargers, which we will talk about further. By the way, it is quite possible to assemble the charger with your own hands. On the Internet, you can find a lot of information on this topic, including device assembly diagrams. But, if you are not particularly versed in electronics, then you better do not risk it and buy yourself a quality charger from a manufacturer that is trustworthy.
2. The process of charging the battery with universal charging.
The charging process with a universal charger is not complicated and consists of the following stages:
1. Wear a protective suit and be sure to wear safety glasses and gloves.
2. Remove the battery from the car by first disconnecting the positive and negative wires from the terminals. During dismantling, you should be very careful and attentive so as not to damage the battery.You will also have to try not to come into contact with the electrolyte, as it is very dangerous for humans and burns if it gets on the skin. Removal should be carried out only after a complete stop of the car engine, otherwise it may lead to damage to electrical equipment.
3. After removing the battery, you can warm it up (if it is already very cold). But just do not use hot water for this. When a cold battery is immersed in hot water, the plates may crumble, which will not have a positive effect on the device.
4.
Wipe the battery with a soft cloth dampened with ammonia. At the same time, make sure that no dirt gets into the electrolyte. Otherwise, your battery will simply be doomed.
5. Dismantle the top cover or unscrew the plugs from the battery. This is done so that during charging the electrolyte "breathes" and does not boil, which, when the lid is closed, leads to explosions.
6. Look at the electrolyte level in the battery plates. If the liquid level is below the required level (which can be recognized by the marks on the battery case), this liquid should be refilled with distilled water. If you start charging at a low electrolyte level, the plates will simply burn out and the battery itself will lose some of its power, or even all of its power.
7. Attach to the terminals "crocodiles" from the charger. It is important not to confuse where the minus is and where the plus is.
8. Only then connect the charger to the mains.
9. Wait until the battery is fully charged. Battery acid may boil while charging and make strange sounds. This is normal. The main thing is to make sure that it does not overheat too much. If overheating occurs, disconnect the charger and let the battery cool down, then continue charging.
10.
After charging is completely done, you should disconnect the universal charging from the mains and only then remove the "crocodiles" from You can find out that charging is complete by the indicators that are on some batteries and almost all modern chargers. Alternatively, measure the density of the electrolyte using a hydrometer. On average, it takes about ten hours to fully charge the battery.
11. Screw the cover back on the battery and reinstall it in the vehicle. A little about security. Charge the battery in a well-ventilated area. And in no case at home. This is due to the fact that during charging, the battery emits harmful substances that negatively affect human health.
There are many different car battery chargers on the market. There are both cheap Chinese options and more expensive ones from well-known manufacturers. When choosing a charger for yourself, be sure to consult with the seller. He will tell you which chargers are better, which batteries are suitable, and just talk heart to heart.
1.
How the charging circuit is built. There are chargers that operate with a constant current value, and there are also those that operate under a constant voltage. The former charge the battery fully, but can lead to overheating of the electrolyte inside. The latter exclude the possibility of overheating of the electrolyte, but you will not see a full charge with such devices.
Neither does the battery benefit. Therefore, another type of chargers has appeared - with a combined charging process, in which the entire procedure is carried out automatically without the participation of a motorist. But such devices are the most expensive.
2. Charger power. Always remember that the maximum allowable battery charge current is 10% of its capacity. For example, if your battery has a capacity of 100 Ah, then you should choose charging with a current of 10 A.
3. Pay attention to the type of charging. There are transformer and pulse models. The former are more reliable, but take up a lot of space. The latter are compact and portable, but not as reliable as the former. So, if you decide to buy an impulse charger, we recommend staying with trusted manufacturers. It will be more reliable this way.
4. Charger power supply method.There are those that are powered by a regular electrical network, and the current to the battery passes through the "crocodiles". And there are those that work from a cigarette lighter, the so-called charging and starting devices. Here you need to pay attention to your personal experience and features of car operation. If you do not go on long trips and return the car to your garage every evening, then choose the first type of charging. But, if you want portability, choose the second type. This way you will never be left without a battery.
To begin with, before the history of this purchase (if someone is too lazy to read, it's definitely worth taking): I became an aliexpress user a little over a year ago. The Mysku reader is a little less, and now it's my turn to add my own drop to this wonderful resource) Who cares - please under the cut)))
At that time, I had just got a two-wheeled friend, and, on the advice of my friends, I began to bribe at times cheaper than sports masters, trial sports, and bicycle accessories. Of course, there was no way without flashlights))) for myself and my brother ... and a rear brake light ... further more: a wireless mouse, glasses, a quadcopter, socks, berries, melamine sponges, a STOP mop !!! Probably everyone who reads this smile stretched out with understanding))) Okay, digress, let's continue: In general, with the growing number of batteries and their "variety", I have been looking closely at this kind of devices for a long time, but the price, to be honest, "bite". And then unexpectedly (as if in group purchases) I came across this device. And so ... until the amphibian woke up, his fingers instantly typed the numbers from the plastic from memory and a few days later the track code was hammered under the label "Charger" on post-tracker.ru. The charger did not last long - on 17.06 it was sent to the post office of China, and on 08.07. the status has changed to "delivery to addressee".
Photo of the device and completeness
The kit included a USB cable (for charging from a computer or laptop), a car charger and a regular 220V charger, already with a Euro plug (although I noted this in writing when ordering, and, to be honest, I was waiting for an adapter ...) 
Now a little about the operation of this device. It has two independent battery compartments, each with a "mode" button that allows you to switch the information displayed on the screen (time from the start of charging, current consumption). There is also the possibility of charging a battery of the "crown" type, but there is no separate key for it, and since I do not have this type of battery, I cannot say anything about this ... So, we insert the battery into the universal holder, the greenish backlight of the screen immediately lights up, the timer starts and the battery type is determined. After it is determined, its type lights up, the required voltage is set and the running battery indicator indicates that charging has started. When finished, the device automatically turns off and the screen shows that the battery is charged. You can use the "mode" key to scroll through the information about how long this battery has been charged, how many milliamperes have been "crammed" into it (it seems to me that this is the real capacity of this battery).
I noticed this feature: when charging a protected 18650 battery, a few seconds after determining the type of battery and its charge mode, it starts to show the percentage of the current battery charge, while for Ni-MH AA this field remains empty ...
A little photo of the box with the characteristics of the device
Pros:
1) The quality of materials, boxes and workmanship for "5+"
2) "Omnivore" (various types of batteries supported, and sources for charging)
3) In my opinion, the lowest price
Minuses:
1) Doesn't know how to discharge batteries (to be honest, I don't need it ... now their cost is so low that it makes no sense to "teach" them, spoiled them - threw them out and bought a new one)
2) There is no possibility of adjusting the charge current, although it is also a controversial minus ... if he really selects the optimal current on the machine, then this is not necessary
