Customer Ratings & Reviews

This portable charger has a good design and feels like it is good quality. Had no issue charging it up from my computer and it charges without issue. Haven’t used the fast charging port yet but other than being a bit long (makes it awkward at times to store/hold it) found no issue with this product. The carrying case is pretty nice too.

It takes a while to recharge the device but once it is full I can charge my phone multiple times. I like the indicator lights that tell you how much power is left!

If you travel, you need this. You'll never be out of power. Each person in our family got one, an we love them. Holds a TON of power!

Anker makes the best. Chargers for next gen devices because they. Are certifies by qualcom and are Committed to making a good product

Anker makes the best batteries around. I'd trust this over a phony non-branded battery pack that would blow up in my face (and lie about the power ratings). High Five Anker!

If you are looking for a dependable external battery to charge that tablet or phone while sitting in the cheap seats of your next transcon flight, this battery is for you.

good power a little bulky and heavy to carry around

this is hands down the BEST portable charger i've ever used. it can charge an iphone nearly fully 2 times with still juice for more. i am blown away. i highly recommend.

Very good quality product, stays charged for long time, took everywhere, helped me in so many situation where i needed to charge my cell.

Great for traveling. I used this on a trip and charged my 2 phones while at the airport both to and from my destination and still had battery life.

I purchased as a replacement for an early unit that had a failure in one outlet ( not Anker) So far its working well Its is also lighter and smaller for same capacity.

I bought this to power my devices on long hikes and for kayaking trips. It takes awhile to charge, but it does a great job charging my devices (phone and bluetooth speaker).

It charges several devices before needing to be recharged. It is a little bulky but i wanted something that I could use several times rather than something small. It works great

Anker power core provides enough juice to charge both my iPhone and iPad to keep me going. Little did I know how quickly it would be needed with Hurricane Michael hitting!

we are always out training this portable charger has been the best one I’ve had charges really fast and gets my electronics up and going again faster than any I’ve had !!

20,000 mAH is just insane. Many charges. Although big, I recommend to anyone travelling, or just needing a portable battery wherever they go. I use it everywhere.

I purchased this device on Nov 14, charging for the required time. It was used for the first time on November 25. It's now December 11 and it still holds a full charge.

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.

This works as an excellent charger for my phone, computer and Fitbit. I always keep it in my purse for emergencies. I highly recommend this product.

I bought this to bring on camping trips, and for when you can't use the truck chargers to charge our devices. It works really great and lasts for a couple days.
