Customer Ratings & Reviews

My husband bought this battery charger because his phone dies during the day and he is up and down ladders all day and can't plug it into a wall socket safely. So he keeps it in his pocket. It is light enough and durable enough to take to work and keep on his person and it charges really well. For the amount of use it gets, it's worth the money.

Good product, easy to use. Charges very well. Would recommend.

I bought this portable battery charger for a cruise I recently went on, it's not the lightest one you can get but well worth the money. My dad uses sometimes when he goes hunting and it last him the whole time he is in the woods.

Holds a charge really well. Takes awhile to charge to full but that’s because it’s so big. Good form factor, fits in my side bag while on the go.

Great design. Not a huge fan of the texture but that’s a personal issue and definitely doesn’t take away from the value. Great that it has multiple ports and utilizes fast charging. Super thin as well

Exceptional value and size/weight not an issue when biking and storing in backpack. The battery will definitely last all day. Great extra battery when making long bike rides (Strava tracking).

Its excelllent , long last. Don't need long charging time to be completed. Its surface is tough. If accidentally it dropps down. Battery will be fine .

This is perfect for me, this charger works quickly when has been a life saver for me. It also holds a charge for a long time without needing to be charged frequently.

Great size, especially compared to my Samsung Galaxy S8+, if not a little heavy if carrying it around by itself. Especially efficient charger with a good C-to-C cable, too!

It holds charge for a good while. Been using in my car since my cigarette lighter is broken. Charge it every few days, good brand, worth it even for the price. A big pro is it charges through usb c

This is a really great product ! I was able to charge my phone instantly and it was worth the money. I always have mine with me and the battery last a great time.

I bought this product fairly recently, and I am enjoying this product very slim, lightweight, and easy to use.

I love Anker products. Their reputation is stellar and so is the performance. I use my phone a lot and I have 2 of these. One to use while the other's already charged up. Good stuff.

Great battery charger to have around when you need something portable. Keeps my phone charged & it is very handy to keep around when there is a storm. Plus, you can also keep this in your pocket. I recommend buy this!!!

Excellent choice! Battery lasts for days. Great for travel to keep kids electronics charged.

Love it. Can charge two phones at once. Great especially if you are at a family gathering or for parties & need to charge phone without finding an outlet

Lightweight and packs plenty of power. I have used this to keep my 12.9” iPad Pro charged up after a couple days camping with no access to power. I had no problem topping the iPad off. I take this on all my overnight motorcycle camping trips.

My family went on the train to Seward and coming home I used the battery charger I was given by my a friend for Christmas. It charged my phone but was extremely hot and I couldn’t turn it off.. My grandson had the Anker PowerCore and I ask him where he got it and when he said Best Buy I ask him for the info and the gave me the SKU number. So I went into Best Buy with a SKU number only for the Anker-PowerCore III 20K mAh USB-C Portable Battery Charger. I told the gal I didn’t know what I needed but here was the SKU and she took me right to the item.. Quick and easy.. Best Buy is great for all my technical needs.. I highly recommend this charger, it is very easy to use and something everyone should have if they travel with their electronics..

Bought it on sale to replace an old one and does the job great! Charges fast and large battery im able to charge my phone multiple times on one charge.

Charge lasts long and the power bank itself is physically sturdy! Needed it last minute and this saved me! Just wish it had more of a variety of USB ports.
