Customer Ratings & Reviews

I have only charged this and have not taken it on a trip yet. It seems like a lot of extra weight to carry but can see that it could be very handy on a long flight or in an all day conference. It is slim and not bulky and well built.

Great power pack. Several recharges. Sized right to keep all my devices going. Very quick recharge

Does what is advertised. Holds a charge and last very long. Also chargers my galaxy note 9 very fast.

I've been using Anker products for a while now, and this didn't disappoint. It's very sturdy and heavy. I can charge my phone or other items at minimum, four times, but I have been able to charge up to six times, depending on how much power the phone has left. But it's a great purchase, well worth the money. Also comes with a carry bag, which makes keeping the cables you need stored in the same place very easy.

Handy portable charger with plenty of juice. The dual ports are very useful.

Great on fast charging phones on the go. Like the fact it has two ports to charge phone with.

Holds alot of batter and charges fast, and i love how there is a different usb port for faster charging

Lasts super long on one single charge, can charge multiple devices

This charges me and my wifes phone 1-2 times each along with our watches. Easy to use and carry

Slim enough to fit in a pocket or carry bag, and has enough to power my devices for a few days.

Love that it charges fast and can charge a lot of phones. My only downside is that it’s heavy.

I purchased this for two all day long travel days to Puerto Rico. I also needed to be connected and able to use my IPad and IPhone on a remote site in Puerto Rico while on business there. I used this device to charge my IPad and IPhone X both during the travel time and two days on-site. Worked as I expected and took all the stress out of four very long days, with recharge at the hotel at night. Had plenty of power to spare and was easy to carry.

Fast charging and long lasting, especially for smaller devices. Compact size for the high mah battery

so far this thing packs a punch and can charge quickly and multiple times. Only downside is the wieght

Great bang for the buck. Lots of power and output options for a small, handheld device.

Got this for those times when away from places to charge and phones, tablets or laptop run low on power.

Great charger and features fastest charging for iPhone while on the road delivering bounce houses for kids parties in Austin! I love having a full charge on the phone so that I can post lots of gorgeous photos of our amazing water slides and other party rental products around the entire Austin area! I highly recommend this charger to anyone delivering bounce houses on the weekends and doesn't always have access to power. Highly recommended!

My son has one and loves it. A teenager has to have his gadgets when we hit the road. The Anker Power Core 20K mAh charger is large enough to handle most situations via USB cable. His charger has been taken on long trips and there hasn't been a situation where we the parents had to provide a different option ($$). So, we love the charger too! We bought 8 as Speaker Gifts for an event we hosted since we knew it was teenager approved!

I bought this charger because it 20,000 mah. It charges great and fast. Happy with my purchase.

This charges my phone FAST and works well in that it is fairly portable despite its size.
