Customer Ratings & Reviews

Keeps charge for a long time & brings full charge of my phone so many times definitely a life saver for my busy life & constantly use of my phone

As recommended by the Best Buy sales person, this portable charger is ideal. It provides a quick recharge of the cell phone and is very efficient.

It was more compact than I thought it was gonna be, which I like. Plan on bringing it with me on vacation to keep my wife's phone and mine charged.

Bought it for my NY trip, had it with me all the time charged my phone and my wife’s at least 4 times. Didn’t loose charge till after several days.

This is a good battery that does not take up too much space when you need to bring it along. I am very pleased with how good it charges.

This is amazing...I frequently have to be places that I use my laptop and phone and need a charger...this one works so good.

Very strong charger if I charge it fully and I leave it for long time it retains the battery ready to the next charge

I've been able to charge my phone multiple times off of one charge and it's still not even below half. Has held a charge for well over a month too.

Works great for cell phones!! When traveling or out taking lots of pictures with your cell phone, product keeps cell phones re-charged.

I was unable to find a better product for the price. Charges to full overnight and kept the whole family full of power for a weekend camping trip.

Definitively has a big capacity to charge phones and other devices multiple times. I wish it had a Type-C connection for other devices

I have become a big fan of Anker products after purchasing this great battery. It is effective and has quickly charged my devices.

Takes a while to charge. Supports Samsungs fast charging. Has a 20000 milliamp hour battery. The only thing that can make it better, is adding USB C.

Nice charger, with 20,000mAh, that will give you plenty of charges. Bit long and heavy. I also have the square 13,000mAh charger from Anker, which is smaller and lighter. Carrying case is nice, but the cinch strap was caught and I had to free it up by cutting part of it.

I've used this religiously since I've gotten it; whether it's been terminals, at home or at the office. It's been fantastic.

It may be a bit heavy but it lasts forever. We took it on an 8 hr plane trip and it lasted well into the next few days without charging.

My daughter loves her Anker powercore portable charger because it charges her phone so fast and has a nice pouch to carry. Very reliable!

This device is well made and very reliable for up to 7 charges. Perfect for people who need something in the car.(don't leave it in the car though)

Swagtastic charger. Fits in most bag pockets and can be used as a weapon in times of struggle.

Bought this for a 1 week away camp where I needed to power my phone (which I couldn’t charge) so I could upload pictures. Worked perfect.
