Needed a balancer for some smaller battery packs. My kiddos toys use a bunch of these little battery packs and they come with a cheap usba plug that just charges but I know that occasionally they need balanced out and I have one balance board with one slot for those types of batteries on my big lipo charger so this was nice to have just for those specific batteries! Works great! Decent size, doesn't take up too much space at all! Well made. Helps extend battery lives. Easy to set up and use. Great value for your money!

I tested this on some newer 2S batteries I got, but had not used yet.I worked pretty goodOne of the new batteries was over charged, so it discharged that battery, and the balance on the cells were pretty close, but according to the charger were balanced perfect when it finished.The other battery was low, and about .8 out of balance, it took a few hrs for it to balance the cells at .2A (curious to test slowest charge especially to balance for the first time. (curiosity)The screen works greatIt had no problem with two batteries @ a 20.1V input from a type C cable.here is why it gets 3 stars, they give you an A to C cable, but not an AC/CD charger cord for it, so buyer beware. unless you have a 65w charging brick for type C you're SOL, this charger is useless to you.IMO - Dont sell me a charger without its own power supply, don't expect me to have a 65w charging brick, or AC to DC 65w power supply the chance that some won't have a 65W USB charger is pretty high, just include one, especially at this ask.The charger fan can spin up and get fairly loud at times, which is fine, and its not extreme, but noticably louder.Overall if it was for the power issue to supply it, it would be 5 stars....
