Customer Ratings & Reviews

This device works great. I used on my trips and always keeps my phone charged and ready to go in minutes.

This thing is a life saver when traveling, can charge my phone 2-3 times from nearly dead!! It's small and rugged, can easily be carried on your person and charges the phone fast!!! Takes a while to charge the unit itself but that's a given with a 7800mah battery.

It charged my iPhone 6 as I walked around the city and I wasn't worried about it dying on me after charging overnight. It does come precharged which is nice. It also shows you how much juice it has based on the lights around the power button. PackGing was also nice

This thing can charge my iPhone to 100% twice. I mainly bought it to charge my camer and phone at the same time if I'm traveling because it has two ports. It charges my devices super fast and the device itself charges pretty quickly. Light weight and easy to use

I love this product and have come to rely on it. Living in a pedestrian town, I no longer have the option to charge my phone between destinations driving. We are getting more and more places with outlets, but in the meantime it has been so nice being able to charge from my pocket or my bag. This is one of those things I should have picked up years ago. I haven't taken the battery to zero but based on the battery's power level indicator, I can get at least four full charges for my iPhone. This would also come in handy traveling. I used to have a different brand that was also a phone case. After a long flight, a long day at the airport or a long train ride, it is a lifeline to keep a phone going. In this case, because of the design, any piece of electronic equipment that uses a USB plug can be recharged. I highly recommend getting one if you find yourself constantly needing a charge.

Works as advertised. A bit bulky and heavy, but I knew that before I purchased it. It was much cheaper than the smaller, lighter model, and I made a conscious choice to place price over size. It works quite well with my Galaxy Note 5. It charges the device multiple times on a single charge, and I have no complaints.

I bought this on a whim when Pokémon Go was released. The store was all out of the heavier usage ones, and this was left. It was overall a good purchase for the price. On a S5 running the game, nonstop, with Pandora music streaming was able to get 6+ hours out of a single charge. Even with the apps running the charge pack was good enough to charge the phone, rather than maintaining current charge, albeit at a slower pace. It has two ports for dual phones if needed; and does take roughly half the day to rercharge, so you'll likely want to do this just before bed time. Make sure to disconnect when not in use to avoid shorting out the internal batteries.

I used this on my recent vacation. Small enough to carry around and was able to keep my phone and small devices up an running as I surfed the web and shot video and took pictures. Never left me high and dry. Only concern I had was it does get hot while recharging.

I got this "Pocketjuice Portable Charger" for charging my cell phone while tracking my hiking and making photos. The GPS and the photo making killed the battery of my cell phone much too fast. THAT'S NOW FIXED thanks to the 7800mA extra-charge. 1. I wish the product would be a little smaller, but I did not find anything else with the mA I needed (above 7000mA). Its like having 2 cell phones with you. 2. It fast charges my Samsung S7, which not all portable power-packs can do. 3. It lasts for 3 charges (not 4 like in the description). 4. Comes with a very short usb cable at home, which is very practical. Don't buy any portable power below 7000mA!!! For a day hike with GPS tracking and photos, perhaps a view short videos, you will need this amount of mA. My worries of running out of power is over.

This charger is small and easy to carry. It recharges quickly and charges my iPhone 7+ faster than any charger I've ever owned. I carry it in my backpack and it will easily recharge my phone 3 times with life to spare!

Ever since i invested on this item, i feel that i never run out of battery juice regardless of the massive usage of my smartphone. Works perfectly with my iphone 6. Wont over heat and fast charging of single or multiple devices

It does what I bought it for. my phone last 3-4 times longer with this attached to it. having 2 usb port is good for sharing. overall happy with this purchase. size isn't too big either, certainly smaller than my phone.

I bought this Tzumi - PocketJuice Endurance 7800 mAh Portable Charger for Most USB-Enabled Devices - Black in a Best Buy Store sale here and I can say that I'm somewhat satisfied with this product because of it's durability and I can use it on any smartphone and even on my tablet. Thanks!

The Pocket Juice is a nicely designed charger with dual charge ports. It charges quickly and has a flashing indicator of charge remaining. It is small enough to carry in a pocket.

Love this charger, I originally bought this for my GF for Pokémon Go, but I end up using it more than her, holds a great charge and can power up my iPad in just under 4hours which isn't too bad for the price.

I have bought 3 of these in the past 3 months. We went to best buy looking for portable charges to help fuel our Pokemon Go habits. We already owned portable charges (13 total, a wide variety of) and none of them could do what this one did. It charged our phone while we played the game. We ended our time playing with more charge than when we started. This little guy packs a punch and I would gladly replace any of mine with this one again. Pros: Charges my phone over 3 times with a full charge. Charges my devices quickly. Holds charge a really long time when sitting idle. Cons: Takes a bit long to charge back up to full.

I priced out similar products and this was the best bang for the buck. Works great. Reaches max capacity quickly and recharges devices pretty fast too.

Small size with extra juice for more than one use before recharging my smartphone. Good looking and easy to use. Bought another one for travel.

Bought this for my trip to Europe. Very useful especially when you are always using Google maps for directions. It drains your phone battery, but this product comes in handy. It gives about 2-1/2 full charges. Last about a day or two.

Great, sturdy charger, and charges fast and at the same time doesn't use a ton of it's own energy, thus able to charge longer if needed.
