Tzumi - PocketJuice 15,000 mAh Portable Charger for Most USB-Enabled Devices - Black

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!

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.

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

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.

For the money and convenience it's difficult to find a charger with such a capacity that's a better value. I was in a hurry to get to Vegas and I needed extra juice for my phone and bluetooth earpiece while on the SHOT Show floor and while trekking at Red Rock. Although it's a little heavier than many other lower-capacity units, I liked that during my week there I didn't have to charge it once and it was in my backpack keeping my stuff topped-off nicely. I even used it on the plane during the 5-hours of flying back to Florida to also keep my Huawei tablet topped-off. It takes a little while to charge it when it's low, but it retains a charge for quite some time and is very easy to use. No issues so far. I keep mine in a small hard-shell case with ventilation. I hope this helps and regards from Florida Jimmy

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 is the best charger. It can charge 2 phones twice before it dies. I take it in my purse because I sometimes forget my wall or charge when going places. I use this at my sons baseball games and I take it with me to concerts as extra charge because I'm always recording. I love it.
