USB Universal Smart Battery Charger for 3.2V LiFePO4 Batteries

Didn't realize when I bought our garden spot lights that they had solar batteries in them that needed to re recharged periodically. Bought this charger along with some backup batteries so I can now recharge my solar lights. Works out perfectly. And, if you have solar batteries for smaller lights that are too small for this charger, you can just put in a button battery behind the small battery so that it connects to this charger for a recharge. Works out perfectly.

I'm striving to be a lot more battery-smart and this was a no-brainer. Quick charge for my small LiFePo4 batteries.

A charger should actually really in-truly CHARGE. Flashing lights for 24 hours does nothing to help me light my patio solar lights. The batteries have difficultly sitting snuggly in the charger, and I have spent 24 hours checking the positioning every time the thought crosses my mind. Even when properly seated, the lights just Flash endlessly. So much for rush shipping to get something that JUST DOESN'T work. I would rather pay $10 more and get somethings that WORKS. Worst thing I have ever bought on Amazon as a member since Amazon has been in business.

works as it should.

Got our solar lights lit up again 100%! Wasn't sure if it was the right charger for our batteries but it is! I guess ours are the standard solar light rechargable battery. If your lights aren't working DON'T throw out your batteries! Try charging first! Especially if its winter or they don't get FULL sun all day.

I bought what was available quickly. Seems to work. Seriously not a fan of everything having to be USB only. USB in this context is pretty much just an answer to a question that NO USER asked.charging 18500s on it seems to work but there is no directional insert and this thing provides no status, progress, or other information beyond a red LED when charging and a green LED presumably when done.may upgrade to something that provides capacity of battery, warnings when there is a problem (these are after all lithium batteries), and a better readout.

Charger works great ! Charges fast and lights are bright when charging.

It charged th batteries like they claimed it would.
