The RAVPOWER RP-PB04 -
The RAVPOWER RP-PB04 looks like most of the other portable batteries on the market. There is really not too much you can do with this type of product to be honest with you. Inside there is a 1000mAh rechargeable battery that should keep your phones and tablets running for a while.

In keeping with the trends going on in the market the RP-PB04 has multiple ports on it. You can charge two different 5V devices at the same time. The dual ports are also there to allow more greedy devices to charge. One port is 5V 1A (Amp) and the other can handle 2A devices. This is a nice touch although we would be interested in seeing if someone can swing two ports with 2A capability. To keep the RP-PB04 full and ready to go you use,… you guessed it a USB cable that is standard on one end and a mini USB on the other.

The top of the PB04 has a power button, although most of the time you will not need it. When you plug in a device the power will start to flow on most occasions. There are LEDs there to let you know the level of power remaining in the PB04. Overall the RP-PB04 is a nicely built product: now we get to see how it performs.
