Whsahans 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)

Absolutely love these! We ordered 2 for a heated seat that we thought came with a battery pack but ended up not. Side note, these can also be used for phone chargers! It is definitely worth the price we paid and last for a long time, during a whole day of baseball games! The size is a little bigger than I thought it would be, but for the power it gives, it’s all worth it!

I purchased a Burrki 5 volt 10,000 Mah heated & vibration massage belt for lower back pain. I used the AI question service on that item webpage and asked for a replacement battery. It replied there was no replacement battery available. I started searching for a battery and discovered this battery. The same voltage and current ratings. I looked at the photos and it was identical to the battery that came with the belt. So I ordered it. It fit perfectly and operates the belt just like the original battery. I'll keep this battery and swap it out with the original so I can always have a fully charged battery available for the belt.

This battery lasts so long when you charge it!

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.

Works great. Holds battery life in my heated vest. C charger and fits in vest well.

Buy two of them so you have a back-up. Mine lasted about 5 hours on low.

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!

Bought two of these batteries. One works well - charges to 100% and lasts as long as the information said it would. Unfortunately, the second battery won't charge. Had to dispose of it. UPDATE: BATTERY I KEPT WILL NO LONGER CHARGE!
