Customer Ratings & Reviews

I needed a portable charger for my upcoming trip and wanted a good one but didn't want to spend a lot of money. This was recommended by an employee and it is exactly what I wanted. It charges from less than 20% to full in less than an hour. I can complete more than one charge on a full battery. The pack itself charges quickly as well but I don't have a concise to me on that. It's not overly heavy. Very much worth the inexpensive price!!

It's really important to bring spare "juice" with you when going out and not knowing where you can recharge your mobile phone in case the battery runs out. This is the perfect solution...so glad I was able to get this at Best Buy Glendale. In fact, my son asked for one and I got it for him, too. I even showed this to my co-worker and he was impressed with the compact size and versatility of this device...not to mention the affordability.

The Tzumi - PocketJuice Endurance 7800 mAh Portable Charger is the perfect solution for those times when you can't charge your phone in a car or an A/C outlet. Last week, while watching a buddy in the Ironman Triathlon, I spent the day taking lots of video and uploading to Facebook. My iPhone would have been dead by noon, BUT this product allowed my phone to stay charged all day and into the night. I recommend it!!!

I purchased this to use with my iPhone 6S+ that is almost two years old and the battery isn't as good as it used to be. I needed it as a backup as I would be going most of the day without any access to an electrical outlet. I was a little skeptical when it said it held 4 extra charges but I've been able to use it four different times and the battery lasts a while in between uses as well. Great when you need it in a pinch!

my son loves this device it charges his phone fast and it fits in his pocket super happy

Lightweight and powerful! Best battery pack I've used. Inexpensive and very effective.

I would often find myself looking for an electrical outlet to recharge my phone while out at the park, mall, or doctor's office which I always found it inconvenient.. This pocket charger has made a big difference for me, now all I have to is hook it and I am good to go. I no longer worry about my phone going dead anymore thanks to the little gadget. I have bought a total of 3 and given a couple of them to my friends.

I got this portable charger for my girlfriend... She was going to Europe on vacation and I thought this might come in handy while abroad to charge her phone.... She used it the whole trip saying it was so convenient. When everyone was wrestling to use a power outlet she'd just use the charger. Then charge the battery charger at night. She said she could get 3-4 cellphone charges off of one battery charge.

Fast Charger and its not too big. you can put it on your pocket with no problem

I was skeptical at first to purchase a portable charging unit as I don't think these units have enough potential energy to charge my device. I was wrong and glad that I am. This device charged my phone quick and does the trick. I see this is not the best one on the market and neither it is the cheapest. This makes it a perfect fit for me. Great price and a great unit. Would purchase again.

it is easy to use and light in weight to hold and help in out doors like camping days

I purchased this item because I was going on a trip and I needed to use my phone a lot to get around. My phone dies fast so I thought this would be helpful. I charged the portable charger the night before but when I woke up it wasn't fully charged or at least all the circles were not solid. It did charge my phone quick when I needed it but it didn't charge it twice as I hoping for. I didn't return it as I thought I would give it a second chance.

we am able to charge very quickly our android devices and the battery life is good

Super easy to use and charge. Super convenient that it can charge two phones at once.

Convenient for when you're on the road and you want to charge two different items

As a Realtor® I use my phone and tablet to show buyers/sellers a lot of visual information in the field on the internet which drains the battery of my phone and tablet quickly. The pocket juice is great, I can keep it in my pocket charging my phone while I give a tour/showing of a property and no longer worry about battery life. Also great when you're camping, hiking, or out at the park.

Great power, fast charging and easy to use. Exactly what I was looking for.

Compared to most higher priced portable chargers, the Tzumi charges faster and holds more charges.

Perfect size for travel. Multiple charges for my phone and other USB devices

a lot of power reasonoble size and good price easy with 2 usb charging port
