Customer Ratings & Reviews

This is a great product, for a great price! This charges my phone up fast. I purchased it on Black Friday and I've been using it every day since then. I spend a lot of time driving to work and using a USB travel cord charger doesn't always cut it for me, because it takes a lot longer to charge. This portable battery pack charges a lot faster than a standard plug-in charger too.

Has 2 USB ports to charge two items at one time very durable and works great price was great as well I would recommend this item to others.

Doesn't charge that fast but keeps my phone alive even when everything is on with wifi and Bluetooth.

I take it every where i go. It just take longer 2 charge

It has a decent size and weight for the amount of power it holds and is easy to carry around while your phone charges. It also charges my phone very quickly, and it can do a full charge on my phone multiple times before it needs to be recharged. Very useful and would definitely recommend!

Small in size but extremely powerful! Holds a charge for those times you don't need it, as some begin to diminish in between usage. The fact that it charges at higher amps is very noticeable. It's very fast!

This device hit the sweet spot between carry-able size, storage capacity and recharge time, and price. It charges quickly, and holds its charge well when not in use. Its dual USB ports, along with a USB mini, is a nice feature too for good flexibility in use.

Compact + lots of capacity + two USB outputs BUT the cable that came with it was a little bit too short + it failed after a few dozen uses. I'm OK with it since I have other cables and I bought the booster at a great sale price. would recommend this to a friend only if at super sale price

This is a compact, reliable and durable portable charger. It has a rubberized cover and can easily fit in your pocket. It has 2 USB ports and it looks good too. However it also chargers good and fast. Great buy!

Ever since Pokemon GO came onto the scene I knew that a battery pack was necessary for my mobile needs. I had done some looking around and different options and pricing, and when I saw this one I knew that it was perfect for me. It gets about 2.5 charges on my phone and does it at lightning speed. It came with a short micro USB cable so I didn't have to use one that I already own. Charging the device itself is even quick (although probably due to my fast charger for my phone). The bulk never seemed to interfere with my every day needs. It IS a little on the heavy side, but obviously the bigger the capacity the more it will weigh. The fact that it comes with approximately half a charge is just icing on the cake.

I bought this Tzumi - PocketJuice Endurance 7800 mAh Portable Charger for Most USB-Enabled Devices - Black in a Best Buy store sale near here and I'm quite satisfied with it's performance because of it's high durability and fast charging capability as a portable charger for my mobile phone.

It's small enough to keep in your purse when you're traveling or just for every day use. It's a good battery pack and keeps its charge for days on end. The only bad thing is the small cord that it comes with. It has stopped working and I bought this back in August 2017. So I use my actual phone cord, which works fine.

A friend of mine has a similar charger and I tried to find it in Best Buy, and instead found this one! When I bought it, my iPhone (iPhone 6s Plus) was on 3% life. My iPad Pro (9.5" model) was on 20% battery life. I plugged both in after leaving the store The battery pack was half-charged right out the pack. Within 30 mins, both of my devices had over 65% battery life! I was very impressed! Needless to say, this device is well worth the price! I plan to buy a lot of my friends and family one of these for Christmas! Great gifts for anyone with a cell phone who constantly worries about carrying chargers all the time!

We bought the Pocket Juice charger on a recommendation from the Best Buy employee. It was perfect for recharging our three phones throughout the entire day during our trip overseas. We used our phones a lot for searching, gps, and listening to podcasts so we used battery life fast on our phones, but we were always able to quickly recharge with the Pocket Juice recharger. A great feature of the Pocket Juice is that it has two usb slots to charge two devices at once. It also weighed less than the other brands available at Best Buy.

Thank goodness for a battery that actually works! Charges fast, holds its charge, easy to use, flat size- great for travel

Works great. Recharges my Samsung S7 in about 1hr 15 min. I can usually get 3 charges out of it. Compact(smaller than my S7 but twice thickness). Cord is cheap. I use my own cord. Very durable. Dropped it twice on the ground and still works great. Takes a while to fully recharge once used up. After about 6 hrs only charged 3/4. Great charger. No power cord. Have to use your own. Short USB cord comes with charger.

I purchased this power bank for my wife as she would often forget to charge her phone and then would end up with a dead battery by evening. Gave her the power bank and she hasn't had any problems since with her phone battery. the charging speed is OK and so is its capacity. Not disappointed with the purchase yet. Will probably update my review once I thoroughly use this product and have an even better understanding of its usefulness.

For the price I paid for, this portable device is amazing. It holds the charge for hours and the design of it is what made me get it.

I was recommended this product by an employee, and I can't tell you how great this battery works! Packs a lot of juice in a small device. Fits in my front and back pockets pretty well, charges my devices quickly, and isn't as obnoxious as other portable batteries. With such an affordable price, I highly recommend this product for those with multiple devices.

Product performs as expected so far. I don't use it on a daily basis for regular charging. Emergencies only and so far it's exceeded my expectations. I have an an HTC Bolt so it doesn't charge rapidly but it does charge faster than old wall chargers. I have had about 3-4 full charges from 35-40% battery life. Thank you TZUMI!
