Customer Ratings & Reviews

Recently took a trip to New York city and this charger was a life saver. It was able to charge two cell phones simultaneously and in no time at all. Kept my little ones tablet charged when we most needed it. Overall amazing product and looking to buy another one.

This is a great power bank , one charge will last for several days , great for charging tablets and smartphones...love it

Can’t say enough good things about this power bank. Massive capacity. Small form factor. Amazing during my last trip abroad!

Nice charger. Great battery life, sleek and well built but a little heavy. Thats the trade off for the battery life though.

Love how small and compact the charger is. It charges my phone and iPad much faster than standard chargers.

Small fit well in my backpack, give quick charge to my phone. Look forward to using it during next vacation

Excellent power source. Perfect for everyone. Strong battery life and very affordable for its price.

This battery is great! Small enough to travel with and still has a large enough capacity to charge devices numerous times.

All these seem to die relatively easily. Not this one. It charges quick and holds its power. I'd highly recommend.

Charged my note 8 like 7 or 8 times when i was in NY. Highly recommend. Has fast charger which makes it even better!

Can charge a phone multiple times before needing a recharge. You’ve got to like the capacity. Great device.

Great little charger; holds charge for a long time. It is compact and powerful.

Love this charger. Not very portable. Heavy. Took to the beach and used it several times a day over a week and didn't run out of juice one time. Con. Very heavy. Not easy to put in pocket both due to size and weight. Overall, great battery though.

Fast charges phone as quickly as a fast charge cord for an outlet! Light weight, packs well in a purse.

Excellent portable charger. Much better than all the smaller portable chargers I've used for the past few years. Was able to charge my Samsung Galaxy S7 for 5 days and still had some power remaining on the charger! Only complaint is lengthy recharge time (well exceeds the advertised 6hr recharge). Researched this product prior to purchase and after using it for the last three weeks I'm very glad I chose the Anker - PowerCore 20,000 mAh charger.

I needed a charger for my iPhone and e- reader when away from home. I haven’t had time to test how many uses I’ll get before recharging. This unit is perfect for my needs. It charges quickly. Only negative point would be it’s weight.

Brought this while on vacation. Last a really long time. Nice and sturdy. The supplied cable doesn't support fast charging and the device doesn't do pass thru charging as well. Other than those two issues I have no complaints

It’s a very nice battery pack. I wish it had a plastic protective case with holes cut out to let air cool it down. Also it would be nice if the case could have magnet or some sort of device to hold on a back pack etc. it would sell fast.

Portable charger with good battery life, charges two iPhones smoothly.

Works for several charges. Easy to charge but wish the charging cable that came with it was longer.
