The jamstik can be charged by connecting the included micro-USB to USB cable from the jamstik to a power source.
a) Connect the micro USB end to your jamstik, then Plug the USB end into a computer
b) Connect the micro USB end to your jamstik, then Plug the USB end into a USB power block which is plugged into the wall - such as the one included with your iPhone or iPad (Recommended)
It should be clarified; that while the jamstik will charge from your laptop or USB hub, it will charge faster with a dedicated wall outlet, while powered OFF.
If you are unsure about the charge of your jamstik, please refer to the "Battery Status" article.
