    The charger is light weight with an easy operation. "Charging the charger"does require an additional connection to the power source. The dial on the charger gives a picture of the capacity. Having the net case makes it very easy to travel with. Charging the cell phone is an easy and efficient operation. I highly recommend this piece of equipment.

    I use my I Pad literally 8-10 hours a day, and its battery won’t last that long. I bought the Anker III to help it last. It’s AWESOME!! Not only will it charge my I Pad twice (yes 2 times!), it charges my I Pad while I use it! So I plug it in, do my work for 45-60 minutes, and I Pad is 75-80 % charged! I love it! And now it’s $15 dollars cheaper!

    I love this power pack I bought it so I can charge my phone and flash light when hiking and rock climbing it has withstood a few drops from cliffs has gotten covered in mud when if fell out of my hydration pack while MTB on a new trail I was riding I cleaned it off and still works great. I can recharge my phone 2 times and a flashlight 1 time before it needs to be plugged in.
