Customers say
Customers find the power bank's battery life impressive, lasting up to 12 hours and providing multiple phone charges. Customers appreciate its compact size that's easy to carry around, and one customer mentions it's particularly convenient for travel or long days outside.
Got this for a heated vest but it also works as a spare phone or Powerbeats pro charger. Easy to keep in the center console or glove box. No issues when using it with the vest. I like the simple digital display. Does not get overheated when using. I also like the weight of it, definitely not cheap and should hold up to some heavy use Read more
Very good battery. It held a charge the whole time I was outside doing yard work and shoveling. It was absolutely what I was looking for. Perfect size and easy to use. Lightweight so you barely feel it there. Very good power. I definitely recommend this battery to my friends. It's a great price compared to others on the market and I was surprised it worked as well it does. Love it. Read more
I definitely appreciate how this pack has several sizes for DC inputs. I have a battery operated heated blanket with a DC input and had no idea what size I needed. This pack did the trick as a swap-in while the battery my blanket came with is charging. I also appreciate that this has a USB-A output as well and something that helps you monitor the percent battery life left. There was no automatic shut off on this battery which means I could use it with the blanket without having to fumble to turn it back on. Hopefully I will get lots of use out of this. Read more
The 30W fast charging performance is very impressive, and the size fits perfectly in one hand, making it easy to carry. I really like the clear digital display that shows the exact battery percentage at a glance. It’s also great that both USB and Type-C ports are supported, which makes it very versatile and convenient to use. Overall, the build quality and performance are excellent—I expect to use this for a long time! Read more
My original jacket battery would no longer charge and I checked with the manufacturer and they charge $80!! I was skeptical about this low price. I opened the box - solid quality , plenty of outlets and nice display. I charged it up, hooked it up to the old jacket and BAM ! Full power! Ran it off and on for days to walk my dog and finally ran it down needing recharging. A great deal and excellent performance I highly recommend. Read more

This battery pack is an amazing product! It can power up 3 devices at once , very compact when on the go, has a long battery life, and can hold a charge up to 4-6 hours. Such a good value for the money. Read more
This battery pack works perfectly with my heated gloves and jacket. The power output is stable, and the 20000mAh capacity easily lasts me through a full day on the mountain. Compact, charges fast, and feels well-built. Definitely recommend if you need a reliable battery for cold-weather gear. Read more
