Been using for several months with different Deleepow AA Lithium Rechargeable Batteries works great saves a lot of money on batteries these batteries keep working till the last second then just recharge.

Charges many lion batteries and even 1.8volt nimh batteries. But I doubt they are 3400 wh

Easy to charge and use for AA devices

Sent 1st one back, one battery would not charge, it was replaced quickly and it is doing it again, does not hold charge very long. A little disappointed

Easy to use with very visible charging status. I’m quite pleased with my purchase. If I’m in need of more & different chargeable batteries, this will be my choice.

1 of 4 batteries never charged. Within a month a 2nd battery wouldn't charge. 1.5 months later only 1 battery accepts a charge. 75% failure rate. Our experience with amazon basics rechargeable batteries has a failure rate of around 10%. Shop accordingly...

Like the fact that there 1.5 instead of 1.2. So far no complaints

~ ~ SHORT & SWEET NOTES - plain, barebones, for better or worse. - convenient size, lightweight. - must be plugged in to see battery charge levels; not an exact measurement. ~ ~ NITTY-GRITTY DETAILS I've had rechargeable battery stations before, but none this compact. Deleepow's is small enough to carry in my purse if I ever needed to, and USB ubiquity means it could recharge easily too. The batteries themselves feel light, and so does the charger. It doesn't come with a very long cable though for me this is preferable - easier to bundle it up & keep it compact. When plugged in it displays how much each battery has left to charge, though not in a very detailed way. Batteries can be removed or added in as needed; as far as I can tell, without trouble. They work fine; I tested them in an old flashlight and it lit up right away! In many ways, it's a bit plain. It doesn't have a lot of extras and is very straightforwards in operation. My only thoughts are, I wish it had some way to tell what energy levels the batteries were at without having to plug it in - but that would almost certainly require passive power draw of some kind, which would slowly deplete them which would sort of defeat the purpose? Either way. I'm happy with them because it means I can use my AA battery items more freely - I dislike buying disposables, especially because you're not supposed to throw those in the trash and I like to dispose of them *properly*. Those also feel wasteful and not cost-effective - but my old station is big and bulky and some of its batteries have escaped to who-knows where. This is small and convenient and about perfect for my needs.
