I was sent the RavPower Deluxe External Battery Charger 8400mAh Power Bank Pack to do an 100% honest and fair evaluation on this product, and in my opinion you cannot go wrong with this product. It is a great little power house!

Upon receiving this I opened the box and took out the instructions and immediately read them. They were easy to read and understand. This RavPower Charger 8400mAh power bank is a nice looking little unit, it has two USB output ports. Output 1 provides 5V/1A while, Output 2 provides 5V/2A. This allows for more than one device to charge at a time. You would use the output 2 for tablets, like the iPad, that can take advantage of the 2A output. Devices that require less power can be charged on either output port, you can then use both simultaneously to charge or one at a time.

When the product arrived it was only charged approximately 50%, there were only 3 red LED lights that were lit up. It has a battery indicator that lets you know how much power your device has. It has an auto shut off to conserve power and has over current as well as short-circuit protection. It also has a flashlight built-in.
