From my home to yours, here's my take: Neutral buy!

Jelly Bean Jeanβ€”November 29, 2025

This battery is small solid material and semi-compact, and it charges fairly quickly. It is great as a backup charger, and when I use it with my electric heated work jacket it does run for several hours with no problem. Also has a digital display showing you the percent of the battery always a plus rather then guessing. The only downside is the weight. It is heavier than I expected, and because of where the battery pocket sits on the jacket I find myself pulling and adjusting constantly my left side to balance it out. It definitely does the job, but the weight is something to keep in mind. Good overall, just heavy. Read more
