Customer Ratings & Reviews

This is the best battery pack that last a long time and you can charge it anywhere.

Does what it should. I can charge my phone twice without recharging the unit. If I had it to do over I would buy a larger amp one.

A great portable charger, definitely held its charge and could easily charge my iPhone at least 3 times.

My wife and I both got them to play Pokemon Go. It has been really useful for many things besides pokemon go. It is also a perfect size for my S6.

I brought this portable charger because I was going to a conference. Worked great and charged really fast. Not big and bulky.

Charges a phone quickly. The more powerful the charger, the heavier it is so it may feel like a second phone but will be worth it if you need access to your phone for a very long day.

Good price works good Good power not heavyweight Long life in battery charge

It is an ideal portable charger to take along for a long time out. With the short cord you can put it and your phone back to back in your pocket.

The Tzumi portable PowerJuice charger is excellent for three-five power charges before being recharged. Good value for the price.

My daughter travels for her college soccer team and this pocket juice keeps her charged and connected to me while she's on the road - priceless!

I have enjoyed my new portable phone charger. It is small enough to fit in my purse and has a fantastic charging capabilities.

Works great with my S8. I used it to charge my samsung tablet and S8 at the same time, and it did a pretty good job as well.

My old cell phone wouldn't keep a charge for more than a few hours, so I started keeping a battery around with me. One day, while on a trip, I noticed that the old spare battery, when plugged into my car, started smelling, so I realized it was getting worn out. I stopped at a Best Buy at our vacation spot and purchased this unit. It was very reasonably priced and worked well for my phone until I purchased a new one with a much longer battery life. I've still got this battery around just in case!

I'm highly impress with this product . It's inexpensive and works like a charm . This is a huge life saver for anyone who's always on the go .

Perfect for my long conference weekend. With long lines everywhere I didn’t have to worry about my phone dying. Fast recharge!

I lost/left my previous charger like this and I had to replace it with the exact same one... I'll keep this one close....

This portable charger helps me when I’m on the go. My daughter can also charge her phone while I’m charging mines.

Needed backup battery for trip to Europe. Couldn't be happier with this product, for sure.

The battery pack is fantastic for travel! I can usually completely refill the S8+ at least twice without recharging. would have been 5 stars if it had included a USB type C cable.

I use this everyday. If I'm not home and I can't charge my phone. I use this battery to charge it and I can charge my phone basically anywhere!
