Customer Ratings & Reviews

Anker makes some great quality items. I bought this power bank for me and a few friends for the holiday's. We all travel a lot and sometimes do not have the opportunity to charge while on the go. The PowerCore 20,000 charged our phones at least 3 times each and could not have worked more perfectly. It's not as bulky as some other brands. Worth every penny.

I thought I would take a chance on this since my friend had an Anker speaker he raved about. I have to say fastest charging for my phone while I'm driving and using my GPS and very quick charging times for the actual battery itself. I wish I would have bought 2 initially. 1 for travel and one for the car. This battery is great. Just buy it already you won't be disappointed.

I got tired of my iphone battery running out when I was not near an electric outlet to recharge it so decided to try this power bank. It charges faster than just plugging into a wall outlet and the charge in the bank can last several days at a time. My only complaint is the size and weight is hard to carry in a pocket so not so easy to carry around with me.

Slim, easy to handle. Lots of power when needed. Two USB ports fast charging.

When I first opened the box my first impression was that it was a little big, it was the first one I ever owned. Then I charged it up and started using it. The portable charger puts a charge on my phone or tablet with no problem in a reasonable time. This portable charger does exactly what is promised. The size is normal when you realize the charger is 20,000 mAh. Great product,

Used this device for a week at a Boy Scout camp in the woods. It kept my S7 charged, as well as helping out with an iPhone. After recharging the Anker, it fully charged a tablet in under 3 hours. Somehow I managed to put this review in the Insignia Wall Charger (which I use to charge the Anker) section. About all I can say is that the wall charger works great with the Anker

Solidly built, powerful and compact. Ideal for travel use. I brought it with me during international travel. I never had to worry about my phone, tablet or other computing equipment running out of power. It's nice to be able to have uninterrupted usage of your equipment during layover at the airport and throughout the flight.

I've had one battery pack from Anker that lasted several years so I know this wouldn't let me down. Bought this for both my phone and my Switch and it has performed great as far as giving me multiple charges worth of power on both devices. Considering it is significantly cheaper than the Switch branded pack, I'd easily go for this version instead.

This is my second Anker Powercore 200000. Originally recommended by a friend this is definitely a good charger. I've been able to keep my iPhone charged over 4 days without having to recharge the Anker. There are 2 USB ports to allow for simultaneous charging of 2 devices as well as 4 charge level indicator lights, each representing 25% of total power available.

Great long life and charge fast. It’s perfect for iPad pro

Pro's: Good charger, can get phone and iPad charged at once. I tend to use it while my iPad is on and the iPad will still charge. Generally will recharge as soon as possible, so haven't taken all the way down to almost "empty" and cannot comment it's recharge time when drained. Cons: It is pretty bulky, but then again, it's a 20,000 mAh battery pack.

Bought this PowerCore 20,00 mAh Portable Charger for my long road trip from Texas to Arizona. Works really well! Everyone in the car wanted to use my portable charger for its speed and long-lasting battery. It fully charged 3 IPhones (I think, it was hard to keep count) and it still had 3 out of 4 lights on (only ~25% was consumed). HIGHLY RECOMMEND!

Long Lasting Portable Anker Battery for Cell Phone and Other Electronics

This powerbank, once fully charged, can fully charge a cell phone at least 3 times before having to recharge the powerbank again. Small enough to fit in bags. Can fit in your pocket as well, however, it does have a little bit of weight to it. It holds enough energy so you can charge 2 phones or a phone and tablet and still have about 50% of energy left.

I bought this item over the cyber Monday deals. It works great. I followed the advice of another purchaser and also bought the turbo charger. Yes it cuts down charging this device by several hours. I recharge this battery pack maybe once a week. I use it almost daily at work on my 12 hour shifts. FYI don't forget to turn it off when not in use.

Love it stays charged for a long time and the quick charge is amazing. Wish it was a little smaller and lighter but understandable because how much juice it holds

Bought this to recharge phones in-park at Disneyland. This battery was able to charge 2 phones to 100% at the same time and still had quite a bit of charge leftover. Little bit heavy to carry around an amusement park all day, but worth it if you depend on the phone for picture taking and checking wait times / making fast passes for the rides.

This definitely is a quality charger. It charges devices at relatively slow speed if you’re using the device but it holds its charge for a while. It is heavier than I thought it would be but still fits in small purses just not wristlets. Be sure to buy your own phone or device cord because it only comes with the cable to charge the battery itself.

A lot has been recommended to me and this charger is good; definitely recommend it. I bought one after using a friend’s which kept my phone charged over 4 days without having to be recharged itself. I like that it has 2 USB ports for charging 2 devices at once. I also like the 4 charge level indicator lights, each representing 25% of total charge.

Was wanting something to take to amusement park trips that would give multiple charges while out so I always had a charged phone. A single charge on Thai charges my phone and backup 5x before I have to recharge it. Only negative is it is a bit heavy and bulky. However, we just toss in the backpack and off we go.
