Customer Ratings & Reviews

Works amazing, my daughter uses for trips with the band and I never have to worry about her running out of battery!

This really is a good anchor product. I take it to work with me every day and I only have to charge it every four days not to mention it’s a great pair with my iPhone 15 Pro.

Awesome Device !!! I bought for my travel vacations, and it will charge my I phone 100% and my 2 kids tablets with one charge !!!

Not bad, but too heavy to carry around. Easy to be scratch. Looks cheap for the price!

Wish it had one more USB port and that I could check the remaining charge without having to plug it into anything or plugging things into it, but it at least shows the exact percentage when you do check.

Nice big charger -love how it shows the power gauge - charges phone many times

The Anker Power Bank (20,000mAh, 15W, 2-Port) - Black is a good quality product and is reasonably priced.

This is great. I charge my watch and iPhone with it next to my chair while watching TV.

Really really good and easy to use it take couple hours to charge after that is really good

Thought was smaller,on-line photo was deceiving. The Anker box even said this battery is pocket size.

The Anker portable charger works perfect fits perfectly in my backpack and I love the indicator to show me how much charge is left. Highly recommended.

It’s great power bank it’s very useful..I love it ..Anker make some good items ..

This power bank is outstanding! It is efficient, compact, and lightweight.

The battery itself is great. The wire that charges it… not so much. The USB broke off the wire within a couple weeks of purchasing this product. Now I have to buy a new wire to charge the battery. I missed the 2 week return window at Best Buy so I am unable to return or exchange this product. It broke a couple days after the window was closed.

Overheat when charging wish that it would work cause I got it at a good price will be returning it.

The Anker Power Bank (20,000mAh, 15W, 2-Port) is an absolute lifesaver for anyone who needs reliable power on the go! The massive 20,000mAh capacity ensures that I can charge my phone multiple times without worrying about running out of battery. I love the dual-port design, which allows me to charge two devices at once—perfect for long trips or sharing with a friend. The LED display is a fantastic touch, providing a clear battery percentage so I always know how much power is left. Anker’s build quality is excellent, and this power bank feels durable and well-made. Charging speeds are solid at 15W, keeping my devices powered up efficiently. Overall, it’s a must-have for travelers, commuters, or anyone who wants peace of mind knowing they’ll never be stuck with a dead battery. Highly recommended!

I was unsure since I never tried thw brand before, but it turned out to be a good investment. Brick holds a lot of charge; and despite being caught unprotected in a downpour, it lived through with no visible water damage (does NOT mean its water proof, but if youre caught unawares it may be okay). A bit hefty, but for the size you are getting a ton of charge for a good while

This one is pretty big, about twice the size of a phone and three times the weight. It makes up for this in charge capacity and is very simple to use. It does take a while to charge if it's low, but once it's full it will fill your phone a half dozen times. Nice to have wherever an outlet isn't handy.

Huge battery pack size. Works great. can charge my phone fully multiple times.

I bought this portable charger for a trip overseas and I definitely appreciated how many times it could recharge my iPhone and still have some juice left over. It is a bit bulky and kind of like a brick, but it’s durable and the quality shows. I love the battery percentage indicator that lets you know how much power is left. I would say it can take a while to recharge from being 0%. I sometimes like to put it to charge overnight when getting ready for bed and it’s either fully charged or almost 100% in the morning. I’ve gotten at least 3 charges back to 100% on my iPhone 13 from being around 20-30%. Give it a chance, you just might like it.
