    We were headed on a 5 hour plane trip for an 11 day vacation with 2 teenagers and my husband who can't put his phone down. Lots of driving while visiting family and plenty of down time with 4 phones and 2 tablets. This device became a lifesaver and kept us all fully charged and no complaining because devices died.

    I got this for a trip to California so I knew I would always have power for my phone and tablet. Well it definitely did the job and more! On the way there it charged my cell, my tablet and my friends cell with juice to spare. This is a must have for the piece of mind of having an always charged device

    Love the little LCD screen which shows you how much power is left, and shows you how much power each device that is attached is using. Lightweight and portable.

    I bought this for when I am on the go. I love doing homework outside in the summer. Great to keep a charge on my tablet (Galaxy note 10.4). Does not weigh to much so I don't notice the extra weight. I don't worry about finding a plug when I am out all day. My phone is always charged now.

    I was looking for a new car charger for my multiple devices that I travel with regularly. This was a much better investment. I love having the ability to charge my smartphone, tablet, smartwatch & other assorted devices while on the go, whether I'm in the car or out & about.

    I like this battery, more than some of the others out there. I tend to use these things on a daily basis and have tried many different units. I especially like this PNY unit because of the digital display. It shows the total mAh remaining for the battery and what Amperage is being drawn by each charging device. It's really nice seeing the exact battery remaining instead of just looking at a few bars or a couple of colored LEDs. This battery has worked perfectly every day for the past 3 months. It holds it's charge well and will charge my Samsung S7 3 times without having to recharge it.

    Nice battery pack, works well with all phones. The indicator is an added bonus which takes the guess work out from when the battery pack needs charging. Overall a good product. A little bulky to carry but that's the standard size for something that is rated at 10000mah

    I love this. Its kinda big, but i dont keep them in my pocket. I leave one on my car, one in my bag, and two in my room. They hold a lot of juice and i hardly ever have to recharge them. Im able to recharge my galaxy note 4 about 3 times before im at 0%.

    It is a great little charger. It can charge two phones at once pretty quickly and holds a charge well. My one issue in the months I've had it is that it once shut off and refused to turn on or charge anything. It still had about 60% battery left and did work again after I plugged the battery pack in to charge a moment. Then it turned on and showed the remaining charge and charged the phones fine. It was weird but very inconvenient. We were out and about and thought it was fried for sure until we got it home and plugged it in to charge...,it's been ok since then though.

    This is my second one of these I have purchased as we add more devices I needed something I can rely on to keep them charged. When device is at 100% it will charge an iPad or iPhone 3 times. This is a lifesaver when you don't have a power source.

    I looked at several power packs, this one had the features I was looking for at a good price. Gives about 3 charges per charge. Great for the times you forget to charge your phone or just don't have time to leave it plugged in.

    You can't go camping without it. It can charge two iPhone at the same time, and can feed 6 iPhone in total! I dropped it several time during hiking, camping, but still good to use. A must outdoor gear.

    The model number indicates the device stores 10400 amps, but each time it has reached 100%, the number of stored amps has always been considerably higher than this amount. Otherwise, it works as advertised.
