Overview
Amazon Basics built this portable charger for rechargeable Ni-MH cells in AA and AAA sizes. Over-charge protection guards the cells, and a USB port adds a second use for travel.
A compact body travels easily, and the listed charge time is short for a basic charger. The listing says little about slot count, USB output or included batteries, so check those before relying on it.
Who it's for
Households and travelers who run remotes, flashlights and small gadgets on rechargeable cells. The USB port suits topping up a small device. People with other chemistries need a different charger.
Pros and cons
- Handles both AA and AAA cells
- USB port included
- Slot count not listed
- USB output current not listed
- Ni-MH cells only
Performance notes
Charge time depends on cell capacity and the current each slot delivers, and the listing states four hours for the charge. Over-charge protection stops the current once cells are full. The USB port is a separate output.
