18650 Battery Charger XTAR VC4L 4bays 21700 Battery Charger USB C Charger for 16340 18650 21700 32650 (VC4L+2.1A Wall Adapter)

This thing is GREAT! However.. You will need a 3a power supply for it to work. It "will" work off a 2a, but the charge rate is slow as death. With 3a it's amazing. I've had it (and have used it everyday) for 6 months with 0 problems! Highly recommend.

Have only used this battery charger two times so far but it works very well. It charges both Lithium-ion and Nickle metal hydride batteries. Thing i like the most about this charger is the nice lighted LCD display, it shows all the batt info that you need to know about the batt's charging process. Happy with purchase and great charger for the money, Only about $30. Also has .5A to 1A charging rate which i preffer because the Lithium-ion batteries will last longer when charged at these lower Amp rates. Charger also features a soft ramping up and ramping down charge cycle to also extend battery cell life span. There are other chargers out there with more options but are more expensive than this model. Anyway,, Gotta take good care of your batteries.

the charger is good as it does the charging work as described; I deducting two stars is because:1. the displayed capacity is not the total capacity of the rechargeable battery, instead, it the capacity during the current charging;2. no discharging feature, such that it is hard to know the whole capacity of batteries; unless, you are fully depleted the battery before charging;so, if you are looking for a product just for charging function, this is good; if you need detect the full capacity of the batteries, you might need look for something else.

Decent little charger for the price. It has held up for the past month. Only thing I wish was that it was able to charge 2 cells at 1/2 an Amp on ch2 and ch3 and 1 cell at 1amp on ch1 or ch4. Because it is capable of charging to cells at 1 amp each. My one and only gripe.

I needed a charger for NiMh & Lithium cells ranging from AAA to 21700 to D cells. This charger handles them all. I purchased the optional wall adapter to make sure I had one with enough current. This was a couple of dollars more, and well worth it to me. I like the way the displays keep me updated on the charging process.

So far so good.

Nice charger. Has a lot of information on screen and seems pretty accurate. Great price as well!
