Best 18650 battery charger
What 18650 charger are you looking for?
There are things you need to take into consideration before choosing your new battery charger. You may not want or need all those bells and whistles. Or maybe your a bit geeky and love to know every detail about your batteries and analyze it.
Safety is of the utmost importance. Unfortunately, many, if not most chargers on the market are questionable and can do more harm than good. Please don’t buy a lithium-ion charger just based on the low price! BTW the list includes chargers for round cells that use slots, unlike a hobby charger. We don’t have any hobby chargers on the list, because we are only talking about 18650 batteries.
These chargers have been tested thoroughly by BLF and CPF member HKJ. The complete reviews will be linked in the descriptions.

This Micro USB Li-ion charger is about as good as the Klarus K1, except for a few things. It can not charge LiFePO4 batteries, and the charge current for a 10440 battery is a little high at 0.5A. Still a recommended charger for single cells, since the K1 has been discontinued.

This is my go-to charger for the longest cells I have, but works fine with shorter cells as well. If you have all sorts of 18650 batteries, with button tops, USB ports, and protection boards, the UMS2 takes it all.
In the review, you can read that the charger stopped a bit before the batteries were fully charged, but mine charges up to 4.22V, which is just a little on the high side. Just keep this in mind when you get one, and double-check yours charging to 4.2V
The only real negative is the micro USB port it has. Also, you have to use the included USB cable to reach the max charge currents.
Xtar VC2L
2-Bay multi-chemistry charger.
- AA, AAA, NiMH, Li-ion 4.2V(3.6V)
- Can handle long batteries, including 18650 & 21700
- USB-C input
- 0.5A-2A charge current
- Small LCD Display with readings
- No discharge or refresh function
- Price: ~$20
The Xtar VC2L is a simple charger with only 1 button for charging most of the general batteries used in flashlights, ranging from rechargeable NiMH batteries to long 18650 batteries.
If you want a simple charger for your 18650 batteries, consider this one. If you also want to charge 10440 or other small batteries, the lowest charge current might be a bit too high at 0.5A.

Before owning the SKY RC3000, I used the Opus BT C3100 primarily for my 18650 batteries.
The charger can handle AA, AAA, Lithium, and even 4.35V lithium batteries (after using the hidden switch inside). It charges, discharges, does capacity checking etc.. for below $40. I highly recommend it! This is an excellent and affordable charger for people who want to diagnose the quality of their batteries.

Miboxer has been active on the charger market for a few years now. I was actually surprised to see the Miboxer mentioned so often in this list, but I can’t help it, because they are great chargers. The test confirms that you can set a charge current manually up to 1.5A per battery. Keep in mind, that this is only possible using up to 4 batteries. If you use all 8 slots, it will be reduced to 0.8A per battery.
For large 32600 batteries, 0.8A is pretty slow, but for 18650 batteries, that would mean a maximum of 4.5 hours of charging… and usually less with lower capacity cells.
A great feature is the wide variety of chemistries and batteries it charges. If you need to charge many batteries and many kinds of batteries at the same time, this me the one you are looking for.
ps. I once bought the Efest LUC C8 a while ago, but didn’t like how it worked with the touch panels etc.. so I don’t recommend buying the Efest in case you were wondering.
