Almost everyone have mobile phones and tablets these days. They help to run our chaotic lives and store photos, videos, and documents now just as our PCs do. However, with more powerful devices and larger media and document files comes the need for more battery power and capacity. Typically when one buys a phone or tablet, there usually is no upgrade path for capacity or larger batteries such as laptops. Most devices do not include any ports for expansion.

Don't you hate it when you are jamming out to your favorite song or browsing the web and you see your battery is low and you are unable to charge it because you are on the go? Or want to record a video but your storage capacity is almost full?
