Best Power Bank, High Capacity Portable Phone Charger 13000mAh, Unique High Speed Technology and Dual USB Port, Exclusive Warranty!

Power "flickers" -- doesn't deliver continuous charge. Didn't realize until I tried to charge my Kindle, which "dings" (for lack of a better word) when you plug it in. A few seconds after plugging it in, I started hearing a constant "ding ding ding ding ding...." as thought it was being repeatedly plugged and unplugged. Tried it on the totally dead iPad next and the battery icon would just flash on the otherwise black screen, rather than holding constant. I charged it up slightly via the wall outlet, and then put it back on this charger while we used it. It appeared to be charging (charge icon was present) but the battery still ran out while we used it. I would love to find one of these things that lasts for more than 2 weeks!

Would be hard to carry in my pocket but I usually throw it in my backpack most the time anyway. Lights are convenient. Charges like a beast! Beast from X Men was bulky but very dependable. What a coincidence...

The power cable stopped working so I can no longer use it.

Really upset about this purchase. It worked great for about a month, but after that it would die out after being fully charged. Charge time also became slower. And if charging more than one device at a time it would be even slower.

I was skeptical at first I mean how much could a a portable power bank actually hold? Well I will say atleast 2 Samsung s5 charges and 2 kindle fire charges! My wife and I both have Samsung s5's and my 2 oldest kids have kindle fires and just to put this power bank to the test we charge all of them with the N7D. We also sent it along with our daughters to stay the night at their grandparents. They take their kindle to play in the morning and sometimes need a charge and we found this power bank easier and safer than sending them a plug in wall charger to use when they need charged.We go camping every year and although we enjoy not using our electronics while we do so we do like to keep our phones charged while their for emergencies. I know this power bank will be great to use rather than having to plug into the car chargers and worry about it draining the car battery.Now to the unit itself. It does come with a usb cord to charge with power bank or to use from the power bank to charge android devices. If you own an apple product you will have to use a cord of your own to power your devices but the power bank will work perfectly with any device. To charge the bank you simple plug the cord to a usb power port and let it charge. You do not have to worry about it over charging so it will stop when the power bank is completely full. The 4 led blue lights indicate the amount of charge the device has. If all 4 are lit the power bank is full and if they are not lighting at all it is completely empty, can't be easier than that.I did receive this product at a discounted price in exchange for a honest review, but I'm glad I did as I have found many uses already for it.

This is a brilliant item if you wish to charge any electronic device in an emergency. It is a little bigger than the size of a pack of cards but heavier due to its large charge holding capacity. It comes with a handy charging cable. It also has two USB slots and a bright light. Highly recommended for those who constantly are on the move and hate carrying cables and chargers for phones and other electronic devices. The low price and great performance make it perfect. I even would carry it around in my suit pocket as I charged my phone. The sense of freedom gained by having it make it something I will carry with me when I am away from home for long periods of time. It is a brilliant device and easy to use, it takes quite a while to charge up fully but once it is charged it just seams to keep on going forever. There are other charge packs available - but they don't have the 'oomph' that this one does.I received this product for free/or at a discount price in exchange for an honest, unbiased review. However the opinions are my own.

We have a couple of power banks currently but this one has a really big capacity compared to the others we have. I love that you can get up to 5 charges from it for your phone. I will say I was surprised because it is a bit heavy. But my husband explained to me that it was a normal weight for a product like this :) Another thing that is a big plus is that it can charge 2 devices at a time. Which I know in our household it is a must with the amount of devices we now have. I like buying from companies that offer a 100% satisfaction guarantee as it makes me feel better about my purchase. Overall this product is great for people on the go and in need of portable charging. We tend to use these the most when traveling and flying.

I got this portable charger because i need to be always in contact with my clients. I am constantly on the go so i have no where to recharge my cellphone. This product is amazing!! I love it, it has charge my phone 4 times and still has enough juice to make another round!! is smaller than my cellphone and charge my phone super fast; fits perfect in my purse. If you are looking for a value product, I will recommend you 100% the N7D. :)
