Great product. Small and light perfect to be taking on a trip. It charges 2 devices at once and it will give you about 45 hours of power without needing to be recharged.

I purchased this portable power bank to cover the moments when I am not in the car to charge my phone or at the home/office to charge it. I am a heavy user of my Galaxy Note and it is a power hog. This power bank is great and holds a high charge amount to keep my phone going. I like the simple feature of shaking the power bank lightly to activate to charge level meter to see how much power is left in the power bank storage. The two USB output ports is great as well and a great feature when needing to charge two devices at the same time. The aluminum case gives it a solid and sturdy build feel while still maintaining a stylish appearance. A really good power bank that does not cost an arm and a leg like many other brands.

This unit is lightweight and not much larger than my cell phone but it packs plenty of juice to keep my cell phone going all day with heavy use.

I bought an back-up battery that plugs into the wall and has lighting and micro usb cables so that it was self contained. I hated it. This is way better. Not only does it charge way faster but using a cable allows you to have room to actually use your device while you are charging it. With the other cables you need to hold the phone and battery at the same time to use. I use this one to charge my iPad all the time. Can charge my iPhone completely 3 times and almost a 4th.

A big fan of this Battery. What sets it apart is the dual charging ports that allow you an a friend to get out of the danger zones of below 15% battery. You can also shake it to see the percentage left in the charge, which is also helpful. Fits in the pocket and is just compact enough although there is some heft. It is super helpful and seems very durable.

The pros: lightweight with enough battery to charge my iPhone 6 two to three times. The power bank has two USB ports which allows for the opportunity to charge two separate electronic devises. Nice aluminium finish.
Cons: The power bank takes awhile to recharge. In order for the user to view the battery percentage remaining in the power bank it needs to be "shaken" which displays the LED dots.

I'm so glad I found this little gadget. I have bought 4 Mophies for my 12 year old's Iphone, that he's had for almost 2 years and for some reason they kept giving out on me. I bought this little gadget and so far it's been charging his phone fast it's slim enough to where he can put in his pocket and the price was a plus. Very Affordable!

I needed a portable charger before a last minute trip and didnt have much time to review.
I must say that overall, this is a great product. Charges up my phone really quickly. Has 4 led lights to indicate how much power it still has. Very sleek and durable. Fits nicely in pocket for traveling so that you can charge the phone if you like taking lots of pictures.

The product worked great, I used it to charge a Samsung Note 5, and although the battery doesn’t support fast charging, it was able to charge my phone from 1% to 60% during the course of a meal. The battery is light and the metal finish gives it a good look. Because the battery has a capacity of 6,000 MAH it can charge two devices at the same time. It doesn’t have an on/off button, so just plug your device and it will start charging it. If you want to know how many charge the battery has left, just shake it and a light indicator will appear. So the battery is light and slim, but unfortunately mine stopped working after one week of use. Overall I was really happy with the battery and tried a store exchange, but unfortunately it was out of stock. Despite my experience I still will recommend the product.

this power bank does a good job. I have charged both my iPhone 5 and iPad Air 2 at the same time, and it brought both from about 25% to a full charge in about the same amount of time that it takes with a wall charger. I only gave it 4 stars, because a meter would be better than the 3 dots to indicate how much power is left. It does seem to hold its power for a long time. I would purchase again.

This is a very good charger. It is small and portable. It charges my iPhone 6 about two times before i have to charge it again. The LEDs that display battery life also work very good. I also like that you can charge two devices at once with it.

Appears to hold full charge for 2-3 weeks or more. Charges phone and tablet. May want to buy another USB connector for another phone so you can charge two phones. Overall happy with charger. Does what I expected. Also great for taking on trips (appears air plane friendly) and fits well in a purse or coat pocket with a zipper. Wouldn't want anyone to lose it.

Holds a charge better than others and charges quickly. Slim fit and can charge two devices at once. The only funkie thing about battery is that you shake it to turn it on.
