ARRIS 12V Rechargeable Battery for 12V Heated Vests/Jackets

The new battery is for 12V heated vests/jackets, not for 7.4V. It comes with a USB-C charging cable, no adaptor.

Specification:
Name: 12V/5V Dual Voltage Output Li-Polymer Battery
Model: YJ-665B
Capacity: 14400mAh/55.44Wh
Type-C input: 5V=3A, 9V=2.22A Max
Type-C output: 5V=3A, 12V=1.5A, 9V=2.22A Max
USB output: 5V=3A, 9V=2A, 12V=1.5A

These 2 modes (DC port and USB port) can not be used together. Which means if you are using this battery to power on the heated apparel, you can not use this as 5V power bank.
