Best portable charger. Anker has became a top dog in the portable charger game. This one is state of art. Charges very fast and packs a lot of power. Sleek look too

Long charging power. Ît can support 2 devices. It is very sturdy & easy to hold. FYI: It does take a while to completely charge so I recommend charging overnight. I highly recommend it.

It charges my iphone quick and lasts days if fully charged. It lets me charge two devices at the same time. I have used it for about three weeks now and will see how it performs over the long run.I like it so far.

Got this for a recent trip. Charged up the day before leaving, charged both my iphone and galaxy at least 4 times before needing to recharge the power core. It's a bit weighty but best investment ever!

Very powerful and sturdy. I have extra large hands, so the size is ideal for me to handle. But all in all, it is an excellent device. And I highly recommend to anyone looking for power and stability.

Very reliable and heavy duty. I bought this to power a warming hunting vest for my husband and it works perfectly. I bought others that did not work but this one came through. Works great.

I like the two port connection and the amount of mAh 20k for the price. Kind of heavy, so wouldn’t buy it for my spouse or daughters. Good for a backpack, laptop bag or car in order to transport comfortably.

When I first charged it it took forever to get a full charge, however after it was at full capacity I’ve been using it everyday for 2weeks and it still has a charge! Only drawback is that it’s quite heavy.

Amazing charger, I used it a lot for 3 days and then had to charge it. Safe for airplane, easy to carry, amazing device! I bought it for a trip but I use it constantly

This back-up battery worked great! Very helpful when used on vacation and away from power outlets for long periods of time. Being able to charge two separate devices at the same time was also super useful.

WOW - I bought this because I was going on a multi-day hike and I wanted to charge my phone and my GoPro. I am SO HAPPY with this investment. It charges quickly, and lasted multiple days.

Easy to use, holds a full charge a long time without refreshing. This is in our 'to go bag' for emergencies. You'd be able to charge your phones multiple times without an outlet.

Used this on my recent trip and it was great. Was able to charge my sisters phone twice, my nephews phone and my iPad and still had juice left! Not too heavy and stylish! Highly recommended!!

A great battery pack, I bought one for me and one for my wife. It looks good, plenty of port options and the solid build quality you've come to expect from Anker. It doesn't get hot from charging, it's kept a charge extremely well and has loads of capacity. Charge this, pop it in your junk drawer, the next time the power goes out it'll keep your whole families phones charged and run a USB fan all night without blinking. During hurricane season for me it's been the difference between a hellish humid night and a cool, peaceful night's sleep knowing my phone will be at 100% in the morning.

great power bank! it charges my iphone really quick and you can charge it many many times before you have to plug in the power bank. the power back takes about 6 hours to fully charge0.

The Anker - Powercore Metro 20000mah Portable Charger retains power for much longer than I expected! Easy to use! Multiple outlets for different devices. I'm impressed!

Awesome charger., very solid, light weight, keeps a long charge, and able to charge a lot of devices. Gives a fast charge. It does take a little while to charge the unit back up, but last so long.

Lots of charges on this battery, heavy duty case. Great when electricity goes out due to bad weather and when traveling and not near an outlet to use regular charger

Love this portable charger for on the go! Sleek looking and holds its charge better then any other brand I’ve ever owned! Very much impressed with it!

It has a great amount of power, stays charged forever, and its easy to carry in a purse or bag.I got it for a weekend convention and knew wall plugs would be a hot commodity. I only recharged it once!
