Works well as a backup to get you through a full data and night.

I like the slim and low profile version. I have seen other brands with very bulky and heavy battery. My only suggestion would be is to have the battery access right by the pocket but in the inside lining of the jacket so it will be accessible without having to take jacket or sleeve out . Just like the older version of the winter jacket.

Pro- it keeps my heated vest heating for a long time. Con- it takes so long to charge that I had to buy a second one to always have one charged

This battery epitomizes everything I love about energy storage. The fact that we, as humans, have invented a portable storage for electricity is basically magic. This battery stores that magic electricity in its tiny little frame and distributes it to my big vest and keeps my body warm. I couldn’t ask for more.

My order was placed on October 21. It’s now October 29, and I haven’t received any updates or tracking information. I originally purchased the vest, but it arrived without a battery — so I’ve been unable to use it at all. This has been disappointing, especially since the battery cost $100.
