Hi all.

Recently I'd like to purchase a portable battery to supply the power of my arduino mega2560 board.  I'm not familiar with the area and would like to ask for your suggestions.  I found this product online and wonder if this can work as the power supply of my board.  Its original feature is to charge the smartphone devices.  Thanks a lot.

Some spec:
- 10000mAh of capacity. Charges all iPhone four to five times, a Galaxy S3 thrice, or an iPad / iPad 2 once.
- Charges one device at maximum speed or two at 3A total. (Apple and Android phones charge at full speed.)
- A lightweight, unassuming solution to life's daily power needs (0.59in thick). LEDs display just how much juice you've got left. Reliable lithium polymer core ensures quality, supplying you with more than 500 charge cycles during the course of its life.
- Input: 5V / 1.5A; Charge time 8 hours. Use a 1.5A adapter for fastest charge times. Output: one 5V /2A port; One 5V / 1A port. Total charge output: 5V / 3A.

If you connect the 5V to the 5V pin of an Arduino, you bypass the voltage regulator.
That is not recommended, because in some rare cases the voltage regulator can be blown. This seems to happen on a Mega board more often than on other boards. I have added a protecton diode over the voltage regulator (from output to input) and I use 5V to power my Mega board.

I have one of these: http://www.thegreenshop.co.za/pPMMG/Mini-Gorilla.aspx which works quite well on the Arduino. Use the USB connected on the Arduino to ensure you have regulated power.
