Customer Ratings & Reviews

Excellent, fast charging. Usually use when device is down to less than 10% and allows SEVERAL full charges before needing to be re-charged itself. My son has a different brand & was impressed with this one - said way faster than his, which was 25,000 mAh!! Highly recommend!!!!

I have used many portable chargers and they can never fully charge my phone in a timely manner. Yes, the charger is heavier than most, but totally worth it. I charged it over night and have fully charged my phone three times and the charger is still above 75%.

Usually I leave it to charge for a day. After that it will last you a very long time, I leave it in my car just in case I need it. Not to big and not to heavy just the right amount. Can fit in your pocket but with just a very miner discomfort. Very great for traveling.

Pricey but worth it. It charged my iPhone X so quick, from like 20% to like 60% in less than 20 minutes. It is also safe to carry on an airline since some power banks aren’t allowed. The battery life on the charger is amazing as well. I would highly recommend.

I'm tired of cheap chargers that the USB ports on quit working, I don't want to have to wiggle cords to get a connection. This one is basically bulletproof, and holds a charge well. Takes a while to get it charged up, but that's fine. Not too heavy to carry around in purse.

This charger keeps my phone charged during all my activities with Pokémon Go and with the 20,000 mah capacity, it lasts me for days! It works great on other electronic chargeable devices as well! Definetly would recommend it as one of the battery packs out there!

My wife bought this to charge her phone when she went to Argentina, it lasted for about 6 charges and rapidly charged her phone. We take it with us now for all trips and it works great. The only negative is that it is a little large and heavy

I ran this the first time all day long and it still held a 100% charge. I highly recommend this Powerbank it's well worth the investment. It's heavy and it's all battery.I recommend using a high quality charging station as it only comes with a micro USB cord.

We bought this to charge our go pro during a trip to England since our go pro battery doesn't last very long. 1/4 of the way into each of our days out, the go pro battery died. This power bank charged the go pro and 3 phones at various times of the day, and it did so rapidly! This allowed us to capture all of the incredible views without having to worry about conserving our battery. We kept hesitating on purchasing it but we are so glad we did. Anker never ceases to amaze us with their amazing line of products.

I purchase the ANKER portable charger a couple of weeks ago for the global citizen concert since I was going to be taking some pictures and doing some videos. with just 2 dots of charge I couldn’t believe it charge 2 phones throughout the whole day back to back. I also like to travel so this would come in very handy in the future! Would I recommended? Of course it might be a bit bulky but it does the job! And it turns off automatically as soon as you unplugged from the phone or when it’s charging to let you know that is 100% ready. Take it anywhere with you it might be a life saver.

This battery conveniently handles charging two phones at once without heating up. It charges quickly from a laptop or wall charger (both sold separately), and the lights on the front clearly denote the current charge level (25%, 50%, 75%, or 100%).

Highly recommended for travel or camping - anything where you might need an extra charge (or three). Never had any issues in the last year of using it. Reliable, fast and versatile.

I bought this for my son for Christmas after I received one as a gift. I can charge my phone 3 or 4 times on one charge. It will actually charge my phone while I’m using it. I took it on a plane too so it’s airline approved. Love it!

Anker - PowerCore 20,000 mAh Portable Charger has a bit of weight to it and understandable for what it can do. Quick charging 2 devices at the same time has been great! Look at Anker - PowerCore 20,000 mAh Portable Charger it is everything they say it is

Great to have just in case you need a charger. We charged 2 iphones and it still had power left in it. Only down fall is it's a little heavy but not that big a deal for what you get. I also liked that it's easy to hold with your phone.

I love the quality that Anker provides, and this power bank can charge a dead Nintendo Switch to full several times when fully charged. It is a bit bigger but still fits easily in cargo pockets and bags.

It is convenient to carry and to have with you on the go when your phone needs to charged. It charges your phone quickly. You can also charge other devices along with your phone with this portable charger. I highly recommend this item.

This thing is incredible!!! I can charge my phone over and over and over and over again on a single charge! It is a little on the large side, but the capacity is quite large itself, so it's not too bad! The battery even comes with a nice pouch!

This charger made my trips much easier because I was on the go and I was never in one place. It kept all my devices charged like my GoPro and iPhone XS. I will highly recommend this to any one. It much better and at a better price than mophie.

I recently got this for a 5 day trip. Used it to charge my iphone and headphones all 5 days and have atleast half the charge left on it. Would definitely recommend getting the Anker 20000 mAh. Only con is that this thing is heavy.
