5200 mAh USB-C Rechargeable Battery
5200 mAh battery
Works great. Lasts about 4-5hrs on high and a lot longer on the lower settings
Flat batteries for the win
These batteries fit great and have a good long life and after having a number of these they all still work as good as new.
lasts all day
This is the second one I got as the first one was DOA so support sent me a second one after a few emails.
Handy Rechargeable Battery
Grabbed a spare for long days in the heater hoodie. Also a handy thing to have to use as an external battery for the phone.
Great long lasting batteries
I like these jackets a lot and plan on keeping them for a long time as I have three so what could be better then having a spare battery in case I forget to charge them after a week or so and the flat batteries work great
