Customer Ratings & Reviews

I bought this for my daughter to use on a recent trip we both took to Europe. It charged both of our phones twice before needing to be recharged. Very handy when traveling.

I hadn't realized I could use a portable charger. I needed something to charge my phone during our Nose Work searches so my dog and I could improve our skills. This worked very well...I was surprised how easy it was to use.

Nice to have when you are somewhere that you wouldn’t be able to charge your phone. We took this to Disney World. We

This item is an excellent buy. It charges my phone quickly and does not need to be recharged often. I use it to charge my phone daily and usually only charge it once a week.

I use this on every trip now. It charges up quickly and it charges my phone quickly. Great to use when sitting at airport gates waiting to board.

I can say Power Juice changes my life, never having to worry about my cell phone battery. Love the freedom.

This back up battery is fantastic! It holds its charge for long periods of time and will recharge my cell phone several times between recharges. I'd highly recommend it!

I love it I take it everywhere I go. Although I have a new phone now and there's no issues with my battery, I still kept it bc its that good! Everyone should have one!!

First time buying a portable battery. Charged my iPad and phone on a flight across country. Definitely a welcome addition to my ever changing travel bag.

The Tzumi - PocketJuice Endurance 8000 mAh Portable Charger - Black is a good product and have been fit-for-purpose. You can easily carry it along with your phone and it wont be noticeable as a charger.

my son needed this for using during school and on the bus when he is on his way to sports games after school

When I have to travel this is the first item I put in my carry on. It fits in my purse. Great for layovers when my cell phone needs an extra charge.

Small and easy to transport. Very simple device that I can count on, even though I don't use it very often. Definitely a good thing to have on hand.

Bought for my son who is constantly on his Galaxy S7. We’ve had a couple in the past and he swears this is the best by far. Not just standby juice but will actually charge your phone and other devices too!

Portable, able to charge our iPhones up to 4x. Highly recommended over a Mophie! We've had enough Mophie's and this has been a much better experience! Price is perfect!

Pros: holds a large charge. Charges multiple items at once. Its universal. Has led display to show remaining charge. Cons: you have to have an available micro usb charger to charge it. Small cable was immediately lost.

This portable charger has improved the convenience of using my wife's cellphone due to its ability to quickly recharge her phone due to its extensive use.

I love this charger for charging my phone on the go while riding my motorcycle.It stays in my motorcycles trunk,and it holds its charge for a very long time which is a +.

When I picked this up I thought it would be a dud. I use it to recharge my Galaxy S5 Active and I get a little over 2 charges from it. I've only had it for about 2 months, but i haven't seen any loss in battery life yet.

We went to the East cost for vacation. Using GPS really drains the battery fast. This charger came in real handy I think it had enough juice for 6 charges.
