Doesn't work, or charges incredibly slowly. Hooked up to a 100w charger, and with my EBL charger, the batteries all took a charge from 25 percent or less, to as of now, at least 75 in an hour. This one was trying to charge the same batteries for 6 hours, and didn't do much or at all. Batteries were a combo of Ikea, amazon basics, and primecables.

Nothing wrong with the product but somewhat disappointed with response from the C/S - I was confused whether this can charge 8x AA or it is strictly 4x AA + 4x AAA because on the description it had line "Can charge 1-8 AA/AAA Lithium rechargeable batteries, with indicator display". However, it is 4AA + 4AAA only. I explained and asked whether 8AA is available and very blunt response making me feel stupid. And then, they took above line out from the description.
