Customer Ratings & Reviews

The charger does what it promises. You can get about two charges out of it when it's fully charged. Nice shape too. Not too big or bulky. The charging cord could be a bit longer.

We were killing our batteries playing Pokémon Go and bought these to help out. They work very well. Hold a charge and recharge our iPhones very quickly.

Awesome and convenient portable charger. I use it all the time, never leave the house without it. It's small, the charge is adequate for my need and the added LED light is a plus!!

This 'stand-by' or 'back-up' battery is small enough to fit into your pocket and is easy to use. Never be caught with low bars on your phone again.

Great small power bank for the price. If all u need is enough power to finish the day, this is perfect to work. I dont need lots of power, so this was a perfect first power bank.

I bought this as a portable option when to charge my phone and my headphones when I go to school and glad to say that it charges both of them quickly.

I had a different charger earlier that broke and wanted to get another one. The Tzumi is really good and durable, charges faster than my old one too. Loving the product so far

This is a very portable power charger that is aesthetically pleasing with the blue LEDs against the black surface. Holds enough juice to charge my iPhone twice.

I use this portable power when I am away from home or office to charge my phone. It works great! It's not an instant fix, but is as good as plugging in to a wall socket.

Has a fairly quick recharge rate and I can get a full charge on my ohine from it i also like the fact that theres a small flashlight attached

Given as a present for Christmas. Great price, great form factor, looks amazing. Tested and refills a 3000mah phone to full once with about 15% left. Very close to spec.

My daughter purchased this as a gift for a friend, but they reportedly like it. It charges their phone quickly, and holds a charge pretty well.

I got this for my wife since her phone doesn't seem to hold a charge past 4 pm. It's small enough for her to carry in her purse and fully recharges her phone on the go

This portable charger keeps the charge for several hours of use. the size makes it easy to handle and the power is more than other charger 2x the price paid for this one

I needed a new battery & my apple appointment was days away I paid $15 bucks for this portable charger it was perfect! Works great, long battery life & charges fast.

Portable charger charges quickly and stays charged for a long time. I only wish it wasn't so heavy and that the charging cord was longer.

This product was amazing. One of the best portable charges I have ever purchased and I have purchased a lot. Will come back if I need another one for sure.

Needed a portable charger to keep with me. This charger will fully charge my S7 Edge. The charger and cord conveniently fit in my eyeglass case.

Holds charges longer then the smaller versions. Fits in my purse for convenience. Will place a better review when I use it more.

it is easy to use and charger is pretty fast. It could come with a carrycase to make bringing it along a little bit less messy...
