Didn’t work for my electric heated chair
on December 13, 2025
Posted by: Heated
I’m leaving a 3 star review because I’m not exactly sure why this portable charger did not work with my heated electric chair. My electric chair calls for a 10000 mAh charger and this particular one I bought is a 20000 mAh charger. So I figured that it would suffice, well it didn’t. Any how, works great charging my phone but not my heated chair.

Haven’t tried yet but hopeful it’ll keep its battery for at least 6-8 hours as I’ll be using it for my battery powered heated thermals during hunting season.
