Product Overview
This is a 2-pack of PKCELL AA lithium rechargeable batteries with a built-in USB-C charging port. Each cell stores 3600mWh, about 2400mAh at 1.5V. An internal regulator holds the output at a constant 1.5V until the cell is nearly depleted. Because this matches alkaline voltage, the cells can be used in devices that don't run reliably on 1.2V NiMH cells. PKCELL rates them for up to 1,200 charge cycles.
The cells charge from any USB power source, and the included USB-A to dual USB-C split cable charges both cells at once. Do not use them in a NiMH or other battery charger. Because the output voltage stays flat, battery-level indicators in some devices will read full until the cell is nearly empty.
