II - Battery chargers
You don't need to have the best rechargeable batteries in the world if you don't have the device to charge them. There are many different ones, and we have decided to offer you the best ones, according to our own criteria of quality, durability and versatility.
Nitecore IntelliCharger i2
Nitecore is a brand specialized in flashlights. The IntelliCharger i2 is a battery charger capable of charging two rechargeable batteries, even of different types or voltages, at the same time. It is compatible with the following IMR/Li-ion lithium batteries: 26650, 22650, 18650, 18490, 18350, 17670, 17500, 14500, 10440 and 16340 (RCR123), and with the following Nickel (Ni-MH/Ni-Cd) batteries: AA, AAA, AAAA and D. An excellent charger, simple and durable.
The Nitecore intelliCharger i2 is certainly not the newest or most sophisticated battery charger, but after testing more than 10 battery chargers of different brands and formats, it was selected by our team for its simplicity and durability. It is able to recharge the most common rechargeable battery formats without any problem. Extremely strong and durable (we have been using one almost daily in the office since 2014, and it still works without blinking, despite several falls). Protected against overheating and polarity reversal, it automatically stops when the battery is charged or after 10 hours of charging. It will charge the battery(s) you place in it to a maximum of 1A (1000mA for a single battery and 500mA each for two batteries). We also appreciate the fact that it can be powered via a cigarette lighter cable (not supplied), which makes it even more versatile.
In short, it has only small LEDs to display the charging progress, and not a state-of-the-art LCD display, it is rather rustic, but it is much better and less capricious than most chargers in the market.
Olight UC Magnetic charger
This minimalist battery charger was designed by Olight (specialising in flashlights and flashlights). Powered by USB, it is capable of charging a very large number of different batteries and accumulators, as long as they are Lithium or NiMH/NiCD type and cylindrical format, with an intensity of 750mA.

A LED indicates whether charging is in progress (red) or completed (green). Reliable, practical and very innovative, an ideal charger for those who need versatility.
Since the launch of this small battery charger, several brands have launched a magnetic charger of similar design. We had the opportunity to test 4 others, and none of them is as good and versatile as Olight's. Nothing beats the original, then. Capable of charging almost all cylindrical batteries, this intelligent charger detects the battery technology and charges it accordingly. Basically, it is capable of charging any lithium cylindrical battery with a voltage of 3.6V/3.7V and any NiMh cylindrical battery with a voltage of 1.2V/1.5V. Almost impossible to do more versatile than this tiny device, which will find its place everywhere with its light weight of 20.5g, for example in an EDC kit or a Bug Out Bag. One of the best chargers on the market, and one of the favourites of the Best Batteries team!

IV - Adapters & converters
It is sometimes interesting to be able to switch from one voltage to another, or from one end to another, for your devices. In this sub-category of our site, we present you with voltage adapters and converters, among the most practical and best practices.
ESR USB-C Adapter
What is more annoying than having an empty power bank, cable and smartphone, but not the ability to recharge it, as it requires a USB-C tip, while you only have a cable ending with a USB microphone. It's also painful to have to walk around with two cables, as your external battery requires a micro-USB tip. The easiest solution is to choose a micro USB to USB-C adapter like this one, offered by ESR, with its practical elastic band to attach it to your cable without losing it. This adapter is also OTG compatible (On the Go), which ensures that your phone and USB stick can be connected and data transfer is possible (up to 480Mbps speed). Simple but essential.
USB to 12V converter
Many devices operating on a cigarette lighter socket are of low power and would not, theoretically, need as much power to operate...
Thus, some electric coolers, some lamps (such as the Goal Zero Light-a-Life 350 for example), some car compressors, etc.., if they require only a small amount of power (written in watts on your device, its power supply or notice) to operate, can be powered via a simple powerbank with this USB->12V converter, which is very convenient. Check the power of your equipment before connecting it to an external USB battery or wall outlet, it's important!
V - Cables
It's nice to have the best external battery, the fastest wall charger in the world or the top power stations, but if between them and your device (Smartphone or other), you don't have a good cable, it's useless. However, the quality and type of cable are essential.

With its Apple MFi certification and lifetime warranty, you can choose it by closing your eyes, Anker quality is there.
VI - Related questions
The key to choosing a battery charger is to make sure it is compatible with the rechargeable battery formats you have. Most chargers can charge the current formats (AA and AAA), but if you want to charge C, D, 9V, 18650 or RCR123 batteries, make sure that the charger you choose supports these formats. Then, choose the number of slots available, to know how many batteries you can charge at the same time. Good choice.
Most smartphones come with a USB wall charger, but these are not always of good quality. To choose a mains charger, first ask yourself how many sockets (ports) you need. Do you want to charge one, two or more devices? If your phone is compatible with fast charging (Power Delivery or QC), ask yourself if you want to be able to charge your devices very quickly. Then choose, depending on the answer to these two questions.
