Customers find the power bank works well for heated jackets, keeping them warm for hours and staying charged for several hours.
Very good battery! Takes a little extra time to charge but it lasts a long time in my heated jacket. Battery is a little heavy but i will gladly carry the extra weight for long lasting performance. Read more
Works great Shows charging level compact design Read more
This battery was a huge upgrade from the original battery that came with my heated coat. Almost 3x more power in the same size battery pack. It also charges very quickly. I’ve only had it a few weeks so far but I’ve used it slot and it has worked flawlessly so far. Read more
Amazing battery, great battery life. Uses on elect. Jacket on low went all day. I have yet after several cold days of use seen the battery indicator go below 55% when the day was over and jacket came off. Honestly I highly recommend this battery pack. Read more
Great extra battery for my heated jacket! This 18400 battery pack was exactly what I needed to use on my heated jacket. I do craft markets and they get chilly. Sometimes I am out there 6 hours so two batteries is necessary. Read more
Nice battery! I read the reviews and should have triple checked, this will not fit a Milwaukee heated jacket. There were several reviews that claimed this. Sometimes the seller changes the product, in the same AD they used for a different product, keeping the reviews intact. I had to return. Battery was a nice compact size. I was not able to use it though. Read more
RIAFOX 12V 1840 mAh Battery outlasted my granddaughter.... She stays on her devices and becomes whiny when the battery gets low. I also use this battery for my devices as well. and all i can say is....this battery is powerful, keeps a xharge for a long time and very light. A wise choice was made when this unit was selected.
