Seems to last very well with the use in a heated vest on my motorcycle
Finally used for proper reviewing. Charged up fine, did take time. Used on some cool weather short bike trips. Medium heat on my vest. Still plenty of juice available. Just gets a little warm with use which is fine because it's in the pocket on the front of my vest which gives me a secondary heat source for that motorcycle ride.. Read more

Powerful Battery
Bought this battery to give me a longer heat cycle for Ororo heated hoodie. This battery also charges my phone. This battery was priced 50 percent less and has over twice the power. It is a heavier battery but I like the better power delivery. I will buy another one for my wife's heated vest Read more
Runs for about 8-12hrs straight)
Charges at 17-18watts. Thats hecka slow. Otherwise fits my needs as a backup battery (although it is mainly used for my heater blanket that uses USB A connector and runs for about 8-12hrs straight) That said, here are the pro's and cons. Pros: - Large capacity (20,000 mAh) - Integrated USB C cable lanyard (works great) - Supports different connectors for heated blankets, pants, vests, and jackets - Supports 4 simultaneous outputs (usb c, usb a, integrated usb c, dc out port for heated apparel) - Stays cool when discharging Cons: - Slow charging at 17-18watts (takes about 3-5hrs) - Easily overheats (extremely warm, doesn't fail just... overheats during charging) Read more
