PTAHDUS 7.4V Battery Pack with Charger Rechargeable Battery Power Bank for Heated Jackets, Heated Vests and Heating Hoodies, [email protected]（37Wh）

Seems to work and keep a charge. Have only had for a month but works in the jacket I bought my wife. One can charge while the other one is in use. Will update as time goes on if something changes.

When I got my coat a few years ago there were no extra battery options I love this if I’m going to be outside for extended time

Wife forgot to keep her original battery charged so it does and I reluctantly ordered this replacement for her heated jacket. It works good and is more compact. We’ll see if it lasts when she inevitably does the same thing this year.

I bought my husband a heated jacket for Christmas as he works outside in the cold. He loves it, but the battery doesn't last his whole shift so we bought him this one as his back up to switch out. It works great we just wish they lasted longer, but overall great product.Thank you

Stay hot at work and games

It works like it should my husband uses it for work.

All good

Bought 2 vest last year and never wore. Now our son starts baseball so took the vest out of box and one battery won't charge. Wish I would have checked it out when I received them last year.
