BIAL 5000mAh Extra Battery for Heated Slippers/Heated Gloves, 5V Spare Batteries Additional Battery Backup Auxiliary Batteries (1 Pair)

Great for my gloves and socks

The batteries keep turning off when ever i turn them on.One battery charges slower than the other.

First note that this is a 5 Volt battery pack set. Some are rated at 7.4 Volts so be sure to choose correctly.This battery pack pair has a convenient option for USB charging. They do tell you not to use high speed chargers but rather slower charging ports which can be found almost everywhere.They have a nice display for status of charge. Convenient charging options. And they are about average priced for their ratings.These plug nicely into my heated gloves and socks with no issues. The plug in jacks fit perfectly.Now I have a spare set of batteries to double my outdoor time in the cold.

Two hours is insufficient don’t purchase these. I would give it zero stars if I could.

I got these as a backup pair of batteries for my 5V heated socks. They are compact, fitting nicely in the battery pockets on the socks. They work well with the heated socks I have. They charge quickly and easily with the included USB-C 'Y' charger cable.
