Customer Ratings & Reviews

Large capacity, phone recognizes it as a fast charger. Only complaint is the battery gauge accuracy. Stays in the high 90s for a long time then plummets. For charging it reaches 99% fairly quickly and then takes 30min or more to top off the last percent

This item seems to work really well and lasts a long time. However feels like it takes forever to charge. So I always charge it over night when needed. It is rather large in size but I would recommend it.

Tuzumi makes all kinds of accessories but they really nailed it when they made this digital display 10000 mah power pack for your cel phone. 22 dollars is cheap for the product.

I bought this for my daughter to take on her spring break trip. I've bought smaller, less expensive ones on the past & been disappointed. This one didn't disappoint. Very nice, reliable charger. Worth the extra money.

This is the best portable charger that I have ever used! I went 4 months without using it at all at one point; after four months, I turned it on, and it still had 98% battery! That is incredible. Most of them lose their charge even when you do not use it at all. Also, it does not turn on unless a device is plugged in and charging. I found that to be a problem with most of these portable batteries as well; a lot of them just turn on when they are in your bag and that is the reason that they do not have any charge left once you go to use them. This one does not do that! I would recommend this portable charger for everybody!

Worked well on a trip and the fast port charger worked pretty quickly. The only negatives are the weight, but that is expected and the short cord, so I just used a different cord.

It is a pretty good size and light enough to carry while you are on the road. The charge indicator is very helpful so you always know exactly how much power you have left. Haven't come across any issues since I purchased.

THIS IS THE BEST PORTABLE CHARGER THAT I EVER BOUGHT & IT'S VERY POWERFUL & I DEFINTELY RECOMMEND THIS TO ANY 1 THAT'S LOOKING TO BUY A POWERFUL PORTABLE CHARGER

It’s a little on the heavy side, but it hold enough juice for three of us to recharge multiple times while at a 3 day festival.

The PocketJuice 12,000 has worked very well for me over the past two months of using it. My main reason for purchase was to have as my main source of charging power while doing ridesharing. Reason being, my vehicle's cigarette/car charging outlet doesn't work anymore. My only two cons up to this point are the extremely slow re-charge time. If it drops down to zero, expect a good four hours to recharge to 100%. Also, be careful and take note of which USB port you are plugging into(especially if driving at night) because if you plug into the orange 2.4 fast-charge port, it will drain before you know it. Would recommend to others.

This is a great charger for the road warrior. I can get about 5 full charges with this battery before I need to recharge it. The only drawback is that it is heavy to carry around.

Bought this charger to carry along when using my gopro. Fairly fast charging battery lasts a long time between charges.

Great invention..solve the problem about drained or low battery..anytime anywhere you have power supply to your gadget.

I love this device, it's the next best thing they have created since the Cell phone. Using my phone all day or multiple errands the battery runs low. Sometimes I have to run out at night and with my Pocket Juice, I can connect my battery and have a working phone. I love it, it's my extra sense of Security.

I got this because I was going to travel out of the country and will be using my phone a lot. At first I was skeptical of how many charges it can hold even if it says 10,000mAh. But when I used it, it really did the job! I was able to charge my phone around 3 times before I plugged the power bank and charged it as well. I'm really glad I got this one!

Easy to use. I like the two usb outputs. Holds a charge.

Charge lasts forever and charges my iPhone very quickly!

Nice battery back-up... good on the go (a little bulky) but it charges a few devices easily

Has a lot of charging capacity. Not the lightest but you wouldn't expect that with a bigger capacity. Easy to use and does a great job.

Almost fully charged out of the box. Lots of stored power. Terrific price.
