Customer Ratings & Reviews

The PowerPack is a good, easy to use choice for a mobile battery pack. For the iPhone, it will charge it at least twice even with some use during charging. I was also impressed by the fact the battery pack comes with a 3 year warranty! That kind of thing is hard to find these days. For all the positives, I have had one negative that I'm not sure if it is an issue with my particular PowerPack or an issue with the product as a whole. When I charge it on an Apple iPhone power brick, it randomly stops charging as though it is fully charged even when it is not. It charges just fine when connected to the USB port of a computer.

Bring Your Own Battery! I travel alot with the railroad and having this in my Grip (travel bag) comes in handy.Small enough for my normal fitting jean and coat pockets. Standard USB charging cable is efficiant. It gives my Samsung note 2 phone 1 full charge from 1% battery left. Small and light so it doesnt take up any room. Now If my extra radio battery was only this small.

purchased it on sale fits in pocket well and can charge my phone from it twice

The charger does exactly what it's supposed to do, it charges my phone & portable blue tooth speaker with no problems. It charges at a good speed & when my phone or blue tooth speaker are fully charged, the power pack charger still has plenty of power left to charge other items. The size of the power pack is perfect, not too big & it fits in your pocket.

Before taking a recent trip to the Kentucky Derby, I knew that it would be difficult to keep my wives, daughters and my phone charged for the entire day. I purchased this unit which was reasonably priced and it kept us communicating and taking pictures all day long!

I bought this charger to use with my IPhone and IPad. Well it's great for the phone but It is not strong enough to charge the IPad, so I still have to carry around two chargers. I could have saved my money and just keep using the one I had.

I really like how small and light it is. I can charge my iPhone 6 at least one and a half times with this little guy. I carry it with me whenever we go to a park or plan to be out all day with lots of photo taking planned.

Love that it's compact and I can charge my phone multiple times. I have a larger battery charger for travel but this is perfect in my purse.

Saw this charger on black Friday and needed one that would fit in my pocket but still give me more than a short charge. So far this charger has done both. Fits in my pocket without feeling like an oversized heavy brick and I get at least 2 full charges with enough left over to charge my blue tooth. Was just what I was looking for.

This item is great for being away from power for an extended amount of time. Times where I have found it to be useful #1 would be out hunting all day. Another is going to our State Fair where you are on you phone looking at the stat fair app or taking pictures all day, continually moving, and never near an outlet. If you are hiking all day. I have used it every time that I fly since from the time I leave the vehicle to the time I get to my destination I don't have time to plug my phone in unless I want to stand at one of those stations at the airport to charge my phone. With this battery pack you just charge it in the morning or the night before and when your phone battery starts to die you plug your phones USB cable into the battery pack and into your phone and put them both in your pocket, jacket, purse, or backpack and your phone will be charging. This battery pack has enough power to charge your phone twice. I would recommend everyone have one of these. You don't know that you need one until you have it.

I bought the PNY Powerpack 4400 because it was a name brand that I could trust and because it was much cheaper than the overpriced Mophie. My wife has used it a couple of times already and enjoys the added piece of mind of knowing she won't be without her phone for emergencies. Very nice looking and small enough to be unobtrusive. we love it.

works great. Easy to use and small enough to travel

Nice backup battery power for phone when it's almost dead and I am out and about - I keep it in the car since my car chargers never seem to work. Other than that, I haven't used it for anything else but it may come in handy when my camera battery is dying and I have more pix to snap!

I run through a lot of charge on my phone and I'm not able to charge my phone while I'm working. If I run low on battery, I just hook this up and I can recharge my phone twice. I don't have to worry about losing my phone because the battery died.

Purchased for boyfriend. He commutes and enjoys watching netflix while on the train/bus. Gives you two charges, doesn't take too long to recharge either. great for traveling/camping!

Purchased to charge my phone while traveling. It's not always easy to find outlets in the airport. This device can charge my phone twice on one charge. Recommended.

Charges my devices 1+ times. Small enough to keep in my pocket. Recharge time a little long, but worth the wait.

This product is a life saver when you are not able to plug in your device. Was very affordable and neat. Met all of my needs. I am still enjoying its many benefits. Glad I got it.

This battery pack is a wonderful addition to my other packs that I have and use to keep tablets and phones recharged.

i found its not charging my phone for twice. verifying this product , i think its better to have more powerful battery.
