Customer Ratings & Reviews

I like Anker products so I went with this one vs. another brand. It's a good power source, just keep in mind it's a bit heavy.

Solid construction, good charge time, and but is a bit heavier and bulkier which is understandable based on charge power

Purchased this charger for road trips, etc. It works really well. I haven’t used the super charge port yet, but it does the job.

Seems to be a good power pac for the price. Ive seen smaller size wise, but this one has more power charging length to it time wise.

My wife uses this everyday at work to charge her phone. She used it when we were at a concert to keep her phone from dying.

After a search for a power cord I could use at home, in the car or on the go, this was by far the best. I really enjoyed the quick charge, in just a short few hours my devices are 100%. My next purchase will be the larger one. I highly recommend this product.

The anker powercore was purchased for an upcoming international flight. Hopefully it charges if the seats won’t!!

After purchasing several portable chargers, i have learned that spending a little more $$ to have the charging capacity you need makes the most sense. I carry my Anker Powercore in my bag or tote / never worry that I’ll be unable to connect or take that perfect pic.

Having this portable charger is very handy for road trips and power outages.

It works well but it is a bit big for pockets and it's pretty heavy I feel, compared to the one my wife has of another brand.

It held a charge for a long time and it worked great helping to charge our iPhones for more than 5 days while on vacation.

Just glad I will have the piece of mind when traveling that my phone will not die and also that it will FAST charge my phone. The cushioned sleeve it comes with is perfect when throwing it in your bag and on the go. Just make sure to leave charging overnight.

It's light and fast. I took it to lots of different places and never failed me once.

A transformer burst leaving us without power for 15 hours. Everyone's phones & portable music were completely charged the entire day. The ANKER Power-Core 20,00 mAh Charger conveniently has both a fast -- fast-charge port, and a standard charge port.

This is a great charger. It is a little heavy so I don’t think it’s as portable as it could be but...

lasted for 2 days of charges with my samsungphone, bose headphone, and gearS3 Fast charging faster than any portable battery that i purchased and with 20k mAh, its all you need for a get away outdoor adventure

Anker - PowerCore 20,000 mAh Portable Charger for Most USB-Enabled Devices - Black is good

Great for charging phone and kindle at the same time. Power lasts a good time

I can charge my phone multiple times with this. If you’re looking for really small and light this isn’t it though.

Easy to use. It is a bit heavy and bulky but provides mutiple charges for my phone.
