Customer Ratings & Reviews

I've only used it once so far, but it seems to be built well so far. I purchased it because I had an Anker Power block (adapter) already, so the pair may work well. I will continue to use it and see how it holds up. It is heavier than I thought it would be, but I'm not used to using power banks.

I've been using this for the past 2 years and it's been great. Snagged it on black friday for cheap too!

Took it back. Does not support fast charging 2.0. I have an Anker 10000 power bank that is 2 years old that works quicker. Took this one back for an Anker power bank that has same capacity but over twice the price just because it charges so much faster.

This battery was super helpful on my trip. It was quick to charge my battery and was able to hold its charge without having the need to recharge and always came super useful

I haven't had to use it much but when i have it works great. First charge the bank to 100 ... that took overnight but it's going strong since!

I was wanting a power bank so I would have to always plug in to a wall outlet to charge my phone. After doing some research I found that Anker power banks were high quality with many attractive features. It does what I need it to do, and does it effectively. The only thing I would change is that it doesn't come with it's own power adapter, and the ones I currently have are of lower capacity, so it takes 8-12 hours to complete charge the bank. Despite the additional charging time, I am still pleased with this purchase and recommend this item to anyone who needs a power bank to charge their devices on the go.

Wish it had one more usb ports, hold charge indefinitely Great storage. Plenty of power. I use for travel. Mainly airports anymore. No free chargers anymore. Charged I phone. 4 times still had 25 percent left on charge

Pretty bulky, but very handy. It fast charges pretty well, but the charging time is quite long. One of those things you leave plugged in overnight.

Nice sized battery, facilitates quick charging for my phone. I can get roughly 3 to 3.5 charges before I have to charge the battery itself.

This has the ability to charge my phone multiple times off a single charge. The percentage display is also a neat feature. Highly recommend for folks that travel.

Very happy with my now nick named “box” charges all of my devices super fast and the battery lasts a very long time before it dies and needs to be recharged

Very portabls to bring, charge fast, convenient to bring

Bought these are gifts and my family are amazed at how long they last and how much faster their devices charge…im very impressed, planning in getting more

With it fully charged it can go days without needing another charge, especially when using ut for your phone or earbuds it gets them charged up fast and its noticable

Great item. Heavy, but very useful. Keeps all my devices charged, can use it in the car, and stays charged for a long time.

Lasts for a long time and essential during a trip that you take photos all the time with your cellphone. The only part to improve is the weight.

Amazing product helps to charge as per guidelines 20000 maH

Great quality. Can charge two devices at once. On type A port and one type C. Very long lasting 20k kwh system.

Holds a lot of juice! I like the display that shows exactly how much power is remaining.

Took a few hours to charge fully but once it was in use, it kept everything charged for a long time and without using much charge! Went to a 3 hour concert and charged my phone and it only took about 10% of the charge! Amazing!
