Customer Ratings & Reviews

I bought the 8,000mAh model and the next day the 15,000mAh went on sale for almost the same price, Best Buy happily exchanged my smaller charger for the 15,000 larger capacity charger. I recommend that you buy the largest aMh charger that you would be comfortable carrying around simply because you will not get the stated amount of advertised up to amount of charges. The claim which all manufactures do, is based on a much smaller battery then what's in the device you will probably be charging. There's a easy to use formula that you can use to determine how many charges you will actually receive based on the size of the battery in your device. The 15,000mAh for me is a good balance between the weight and the actual amount of full charges I'll receive in conjunction with the size of my phone's battery!

Easy to use. Provides fast and stable charging for my cell phone battery. Great value

This is an awesome battery charger bank. Great for batteries of all kinds. Perfect charger for my drone, cell phone, juul and wireless bluetooth earphones. Great when your out somewhere without power. Love it!

I got this on clearance for half price and it was a life saver on my overseas trip. I charged it fully before I left and used it for several phones over for days and it gave a quick charge.

I have purchased a few chargers back when they looked like a roll of lip balm and couldn't totally power a phone but could sustain it for the rest of the day. This is the third one I've purchased because it has gotten me through a few situations when traveling or I've been out in the field all day. I've given one to each of my sisters and they are beyond overjoyed with its performance. It has two USB ports so you can simultaneously charge two devices and it recharges via a micro USB port. A short 5" cord is included but you can use a longer one if you have it. You can recharge it using wall plug from most phones (it doesn't come with one) and the type of volts will determine how quickly it would charge. Using an original iPhone wall plug took me around 8-9 hours being fully dead so if you want it fully charged for a trip, make sure you do it overnight or well in advance. When looking to purchase a portable charger, I look at the the highest amount of milliamps (mAh) I can get for the price and this is a reasonable choice for price/power/weight. They also make a 20,000 mAh charger but it's going to be bigger and heavier. It may pose an issue if you're trying to travel light or for ladies that want to use a small purse. All in all, a good product and I highly recommend it!

The rubberized coating on this is superrr nice, definitely an upgrade from my Modal battery I had. TONS of battery in this, love it and use it today. The LED is very bright blue and is on when you're charging it, so careful about this at night if you're trying to sleep.

It's a little on the heavy side, but charges fast and has a lot of charge left over. Got the 2 year warranty in case it dies like our last one

This is the most compact 15000 mAH battery pack i have found and very reasonable price. It has a little heft to it but very acceptable for the power. It will keep me going for the day if I am on site burning a lot of juice taking photos and using tablet and phone a lot. I highly recommend this item for a mobile professional. I have the 12k and the 15k units. It also provides peace of mind in case of power outages.

This massive charger comes pre-charged, making it invaluable at the moment you buy it, especially if you are in a pinch for power. Its capacity is so high that you can charge multiple times, even under a heavy load. I've used it on my phone, iPad, galaxy Tablet, bluetooth headphones, and my Gear2 Watch, and had pawer to spare! VERY happy with this charger!

This product surprised me as small as it is it charges my multiple devices at a fast rate . This is the third type of portable charger I've purchased ( some more expensive) this one is the best for the price .

I love the size of this backup battery and that it has two USB ports. It fast charges my phone and last several days before I have to recharge it.

Packs a lot of power in a somewhat small unit. Very handy for carrying in backpacks for hikes. Recharges very quickly. I recommend this unit.

I bought this charger for emergency purposes since it is important that my phone has a charge all the time. We went to Disneyland last month and this charger certainly proved to be reliable. We were there for over 12 hours and were constantly taking photos and videos with our phones. As expected, my phone battery was quickly drained from constant use. This device saved me from worrying about capturing all the wonderful memories from our visit. Even after keeping my phone charged for at least half the day, the charger had so much more to spare at the end of the day. Although it is quite heavy to carry in my purse, I don't mind lugging it around all day during trips/vacations for peace of mind's sake. I highly recommend this charger. You won't be disappointed!

This battery last forever. I have used it multiple times since first full charge and it definitely helps during long sessions of Pokémon Go. A little on the heavy side, but with the battery size, it is expected. Fits perfectly in either a pants pocket or cargo pocket on shorts. Get your own cord to attach to your device, since the included cord is really only for charging the battery and is quite short.

I have an older phone which still works great but was losing battery power quickly throughout the day. Rather than pay hundreds for a new phone I purchased a replacement battery & this pocket juice charger. The charger works great! Twice as fast as my sister's cheap charger and with the dual USB ports I can charge my phone & my 10in tablet at the same time! Yes it has plenty of power for that. For the price it has more power than any cheaper chargers and even some more expensive ones.

Had the 12500 mAh and decided to give it to a family member . Now have the 15000mAh and I carry it everywhere. Provides quick charge to my cel. Very useful when spending prolonged time away from an AC outlet

This pocket charger is amazing product that has saved me from a dead phone many times. Easily fully charges my iPhone 7plus in less than 1hr at least 2-3 times over and charge my Bluetooth headset. A+++

Needed an inexpensive portable charger for travel purposes with more than one USB at a time. Found it with this product. Charges very quickly but does not drain itself quickly so that was good. I was hesitant to get this one as it is bigger than its smaller counterpart but was only 3 dollars more for a full extra charge. The charging cable it comes with is very short and not very practical but you can use your own longer cable and you’re good.

After Hurricane Harvey struck, I learned that I needed a rechargeable power source. There's plenty out there. But few are this large and lightweight. Really recommend it.

This charger has a lot of power in it, i used it to charge my iPhone along with my iPad pro and it provided them both with a fast and long lasting charge
