5V2A 20000mAh Battery Pack for Heated Vest Heated Jacket Power Bank for Heating Electric Vests Jackets Coat Hoodies Battery Pack for Man Women Heated Clothing (Not suit for 7.4V Heated Clothing)

The battery is dependable. It takes a few hours to fully charge. Once charged, works great. Only downside, if you can call it a negative, is the weight of the battery. Kinda heavy for a heated vest

Great quality

I purchased this battery because I knew I’d need a backup for the one already in my heated vest. It takes quite a long time to fully charge (overnight is best), but it also can keep my vest toasty warm for a whole day out in the cold. My one concern is the weight - it’s quite heavy, and because it’s bigger than a battery with less storage capacity, it essentially means you can’t put much into the left hand outside pocket because there’s no room. Highly recommended!

Works better and longer than the original battery. Takes 2 days to fully charge but I can sit all morning (4-5 hours ) and the night hunt (4-5 hours ) before the battery is drained. Ended up buying another so I can keep a rotation going durning hunting season.

I bought this battery as a main battery for my wifes heated coat. It lasts much longer than the small battery that came with the coat. It is easy to set up and charge. Nice small size and slim. Greta price too.

Love this battery pack so far - only have had it for a week and have used it two times connecting to a seat heater I was using during camping. The battery power didn't even go down for the few hours each night i was using the seat warmer. So far I think it's a great product. Looking forward to having this when the power goes out to charge our electronics.

I ordered two of these for my needs. Excellent battery storage if you scope long hours. I never worry about shutting down early because of power.

I ordered a Thermalux heated vest for my wife begining Dec along with their 10000 Power Bank Ultra battery. The battery would not work with the vest. It kept turning off when connected. Yes I tried everything and finally sent the battery back. Finally received a replacement and the same thing happened. I knew the vest worked because I connected it straight to a USB wall outlet and it worked fine. Decided to buy another battery from a different source and more powerful. This 20000 power Bank was advertised especially for heated clothing. Works like a charm. Only problem is its weight. It is quite a bit heavier than the 10000 batteries but what the hell, now my wife can use her vest 2 months after buying it for her. She has not used it long enough to rate it for longevity so reason why I gave it 4 stars. Delivery was extremely fast, only 2 days.
