Poweradd Power Bank, 15000mAh High-Capacity Portable Charger with Dual 3A Output & USB C Input, Fast Charging External Battery Pack for iPhone 12 11 iPad Airpods Samsung HUAWEI Tablet-Black

So far happy with the battery packs, charges via USB-c so I don't have to look for or carry too many different cables , it's quite light but quite chunky shape (cigarette packet size)..only downside I can see is there are only 2 outputs but hey how many devices do you need to have plugged in at once. I have one that's used to power action camera on the go and the other used for keeping my phone charged - even carrying 2 doesn't add too much weight...

I bought this powerbank to use with a heated vest. All I can say is it will last all day on full power. That's all I wanted it to do

Only used once for about 5 hours but still seems to have over half charge remaining.

Brilliant size for my heated jacket, keeps a good charge

Lovely item well worth its price.

I can charge 2 phones and still have plenty of battery

Amazing product

This battery pack has proven to be fantastic, great buy!
