Fast, Convenient, 20k capacity
Matthew K—November 28, 2025
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! Read more

Excellent Slim Power Bank
0405069—November 9, 2025
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. Read more

Super fast charging! ⚡️
Wendy McNeil—August 28, 2025
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. Read more
