This one (I have sinned and bought it from Amazon): POWER BANK

My wife has a 10k Lonkuu that works very well for charging phones. I tried to borrow it for a winter camping trip to heat my electric vest and it won't even turn on. For some unknown reason, not all power packs will work with all vests. My jump starter will work great with the vest but it's too dang heavy to carry around while hunting. If you have or are thinking of a heated vest, do some checking with the vest manufacturer to make sure you get a power pack that's compatible.




I am going the "carry small cheap auto charger" way my self as it will keep up a phone, an Olight, and a plasma lighter for at least a week.

I suppose the addition of a small soft foldable solar charger wouldn't go amiss for longer periods.

Damn I wish all these toys were available when I was young.

These are my opinions, feel free to disagree.
