Customer Ratings & Reviews

Running a lot of apps can drain your phone battery very quickly. With this portable battery you'll never be left with a drained battery.

This is the only portable battery that you ever need to take with you. It works good with my phone, tablet, and my kids ipads and iphones.

We bought this for a recent trip we took to Hawaii and it was great . Highly recommend getting one not only for travel but to have always

Already owned one of these so bought two more on sale. I get multiple iPhone and iPad charges from one charging. Great for camping.

This is a great product, it is heavy though but we bought it for function not weight and it has the hugest power rating of any in the store.

Absolutely amazing product that countless times has saved my day. More time for business and ultimately FaceTiming my family.

Perfect for everything I need on the go. Whether I need it for my phone, iPad or camera I'm set for whatever battery issues come my way.

I was looking for a charger to charge both our phones at the same time and this one works. It has enough power to charge them 2 times.

I actually bought it for my son . It must work well he hasn't bothered me for several months . I haven't heard any complaints about it .

Although, the battery doesn't seem to charge 20,000 mah worth of battery it is good for the price I payed which was 17.99. May charge my Tab S two times.

Works as expected. Takes a while to charge, but once it does it lasts a while. Not for carrying in your pocket, more like for taking with you to work or on trips.

I purchased this while camping up in the mountains for 5 days. It's worked great! Charged quickly and still had battery life let over.

I always run out of power on my cell phone or I Pad and this is just what I need to recharge. Worth it if it goes on sale again.

really useful, i used it on a trip to las Vegas and it saved my day !! No worries on battery !!! I loved it totally recomend it

Face it we all linked up somewhere right?! this not only charges my devices fast but it's always there when you need it pocket size!

This portable charger will fully charge my Galaxy S8 Plus at least 3 times before having to charge it again. Highly recommend.

Lots of charges for all your devices. If you're going to go for a power pack, this is the one to get, at 20,000 mAh.

Tzumi - PocketJuice 20,000 mAh Portable Charger for Most USB-Enabled Devices - Black Great if your a traveler

Love it! The best charger I have had. It hold the battery long and charges my phone more than just once on a trip or walking around.

I love this charger! It has enough juice to recharge my family's 5 iphones and still has enough juice for a second charge!!!!
