Arcenet AL400 4000mAh Portable Battery Pack Phone Charger Power Bank Batteries Ultra Light Slim Pocket Size Backup for iPhone 6S 6Plus iPad Samsung Galaxy Nexus LG HTC Motorola Black

Love the sleek design and it is easy to fit inside a female skinny jean pocket. I have an iPhone 6 so I have to use my own cord but it's not an issue at all. Charging LED blue lights are probably this products highlighting feature, and that way I KNOW how much battery is available.

Big help when battery is low, and you want to continue to play pokemon go!

The In port is a little loose and when jiggled would stop charging the bank, but otherwise works as expected

This is a review of the Arcenet AL400 Power Bank. The packaging was a bit bland, it has a white outer sleeve, with black writing displaying "ARCENET." Inside of the white slip cover is a tan inner box that held the power bank. Once you remove the white slip cover and open the box you will find the Arcenet AL400 Power Bank, USB to micro cable and the instructions. The instructions were easy to read and follow. The diagrams were helpful as well.The Arcenet AL400 Power Bank has a power switch along its right side about a ½ inch from the top, when you press it you will get up to 4 lights depending on the Arcenet AL400 Power Bank’s charge at that time. I thought this was a nice feature since it takes the guess work out of the unit’s charge. Upon turning it on, I noticed that it was at approximately 75% charge. I attached my Kindle Fire 8, that only had a 7% charge, to the power bank.With the Kindle Fire attached, I wanted to run a timed test, to see how long it would take to charge and how much battery it would use. It took 2 hours to charge the Kindle to 90% and it drained the power bank completely. I then put the Arcenet AL400 Power Bank, with a flashing single light, on charge. It took 4.5 hours to get a full 4 light (100%) charge. Lastly, I attached my IPhone 6S Plus, with a 29% charge, to the Arcenet AL400 Power Bank and it took 3 hours to give me a 100% charge.I found this to be a nice battery, and would recommend it to anyone looking for an emergency charging option. The device will give you the ability to keep your phone charged. It’s small, lightweight and inexpensive, it would be easy to carry anywhere you go from hiking, camping or even a day at the beach.Pro: Inexpensive, small size, light weight.Con: Only has a limited charge.

The battery pack I ordered/received is black (the picture now shows a different battery pack). So my review is of the black version with the USB ports in different spots (USB, micro, USB) and the power lights are smaller and in the middle of the pack.I like it. It charges my phone incredibly fast! Even the small cable that came with it charges my phone super fast (if I use that directly instead of with the battery pack). It actually charges my phone (Samsung galaxy s6) faster than my plain old charger. The only downside is the battery pack's weight. When you're out you don't really want to carry a lot of extra weight with you, and this pack is somewhat heavy.

Thanks
