WhsahansWhsahans 5V 2A Rechargeable Battery Pack for Heated Vest 10000mah Heated Jacket Battery Power Bank for Heated Vests Heated Jackets Heated Hoodies for Men Women(No DC Port, Not Suit for 7.4v)

Good price and quality.....

Worked like a charm

Takes a while to charge but definitely feels like it makes the difference in it lasting a long time too! Very durable, hasn’t broken, pretty hefty for the size of your palm!

Not sure if it's the vest or the chip in the battery but in order to fully turn off the vest this is used for, it must be unplugged. The buttons on the side seem to do nothing. It lasts a long time, though, more hours than I've needed it so far. It does take a while to charge but nothing compared to the over 8 hours I've had it working in the field. For the money, being half or less of what competitors cost with a battery, t is a good deal and and for me, worth the hassle to turn off. That hassle is worth noting, though, because if driving let alone riding a motorcycle, that means stopping and being safe about getting to the cable. Even if carrying things this can be a bit difficult. One other thing worth noting is that some heated jackets cost less but I bought this to occasionally wear under a motorcycle jacket, so if you don't need something like that, you are better off buying a full jacket, especially on sale days when they might not cost much more than this setup.

This battery works great and is half the cost of the battery from the manufacturer. Very glad I purchased it. It is very easy to charge and use, and keeps my vest toasty for long hikes. After a 2 hour hike the battery was still 3/4 charged.

Works well and stays charged for a decent amount of time

Took a long time to charge

Super quick charging - a little heavy but very reliable
