Lasts a long time and can charge a phone a couple times. We use these to power our heated stadium chairs and it works great.

Loved this so much from a purchase at Best Buy, by girlfriend wanted one. We use them everyday! Perfect for charging on the go, especially if you forgot to charge your phone. I get around 3 full charges. I'm using it as I'm writing this review, lol. The super-fast-charging is fantastic, and the built in charging cable is so convenient. These and it's 20k size are the sole reasons to get one. I got some Velcro to put on the back of my phone and charger so the charger can stay in place. I highly recommend doing this. Just a tad heavy, but you'll get used to it. Nothing as bad as others I've tried, and they didn't even hold as much power. A rating of 6/5 easily. Great job Anker!

This can charge my Pixel phone at least 4x!! It is heavier/thicker than expected, but love having a bunch of portable power!

Gift for my daughter she requested this brand so far she is thrilled with the new look computer her old one and the quickness of charging along with how many times she can use it before needing t to charge it

This PowerBank is excellent, 20k capacity, slim design, USB C, 30 watt output, and built in cable makes this my go to choice when traveling. I have other 20k Anker power banks but they are too bulky to carry when exploring. I wish it was a little cheaper, but 10/10 would purchase again.

Works great. Love the built in cable

I can't believe how quickly this charges my phone. I'm able to plug in my phone and keep it in the same bag that is provided, making it compact and easy to carry. The device needs awhile to charge, but that's nothing compared to it's ability to fast charge my phone. It's one of the best purchases I've ever made. Just a quick note: it is rather "slippery" so make sure you have a good grip on it if you choose to hold ot while you charge or keep it in the drawstring bag that comes with it.

It is really good and it has a really good fast charge
