Customer Ratings & Reviews

Great quality. Had one and used it under extreme conditions for 30 days and it held up like a champ. It charges my phone 5+ cycles in one charge. Getting another one to gift out.

I took this on vacation to the mega amusement park. I knew both my android and my wife's i phone would need recharging. we were gone all day with no place to recharge from 7am to 8pm. I just plugged both phones in at the same time in the backpack and we did not miss a picture or lose communication. Works great.

ANKER IS MY BACK-UP CHARGER,TAKE IT WITH YOU ANYWHERE YOU GO,VERY PORTABLE,RELIABILITY PROVEN

Charger IS FAST!THAT'S GREAT!BUT HEAVY LIKE A GUN.

Love these Anker battery packs. My second one that Ive purchased. Still works great, several charges off of one charge.

I had a different brand before for my backup power source. It was stolen out of my truck. Thought I would try this brand and very impressed. It has very fast charging.

Very light weight. The high capacity of the battery allows me to recharge ir constantly have my phone charging while running running draining apps or streaming.

bought this since i would be at a tournament all days for a few days and wanted to keep phone charged so i could video tape games. worked out way better than i ever thought

Got this just Incase our power went out during a hurricane. Can charge about 7 full charges depending on what you are charging. Use it all the time.

Good little brick to chare multiple devices at once

Took this on a trip to Europe. Kept my phone ready to take photos and use for maps. I love the size and it’s lightweight.

This is the best portable charger I've ever gotten. I'm shopping for one as a gift and will be getting the new version of this one.

The Anker - PowerCore 20,000 is a compact but powerful charger. One charge can recharge 5 phones and still have power to spare. Always had goood results witrh Anker.

Although at first I balked at the price, it has exceeded my expectations. It had a MASSIVE battery and ha recharged my phone and iPad multiple times on one battery.

I love having this as a power backup. It's straightforward and simple. It works wonders on my phone, but a bit slower on my tablet.

I purchased this battery to power some under-cabinet lights that work off of USB. It fit's in the space I needed it to and will run without a recharge for a month

Takes a long time to charge the first time, but not so long after the first time. Having said that, it stays charged when not used for a few weeks. Love it!

Solid built and reliable This is an extremely good product for the price. It is a little on the heavy side if you have to carry it for a long period of time. I got it for about 50 bucks at a time. Considering the cost of these coming down I would wait until it is on sale for that or less.

I have had it for a month and charged my phone from 30% to 100% with the lightning charger and the battery is still showing full bars. Absolutely love it

Charged it once and was surprisingly satisfied with all the electronics it powered. I recharged it after a few days and really didn't have to. Great buy!
