For the 5V vests
1 product from $37.99 Two USB outputs, USB-C input

The 12,000 mAh bank is made for our 5V heated vests, the same voltage as the 10,000 mAh bank that comes with each vest, with a little more capacity. It has two 5V 2.4A USB outputs, so it can run the vest and top up a phone at once, and it recharges through a USB-C input. It measures 3.5 by 2.5 by 1 inches and weighs 0.39 pounds.
It does not fit our graphene jacket, which runs on a 7.4V pack. Check the voltage printed on your garment's cable or label before you buy a spare. If you fly, a power bank goes in your carry-on, never in a checked bag. Our heating guide shows how to work out its watt hours.
This power bank is part of the Soleilwear collection, at $37.99 in our last catalog update.
