5VDC USB Input to 12 VDC 1A Max Adaptor Cable with 2.5x5.5mm Output Connector
This neat cable adaptor allows you to power your 12VDC devices from a standard USB connector. Basically, it takes the 5VDC input from any USB connector and steps it up to 12VDC. The amperage supply varies depending on the USB output source. Note that a regular USB 1.0 and 2.0 connectors from a computer supplise 500 mA whereas a charging brick can go up to 2.5A depending on the model. The higher amperage input the cable takes, the higher it can supply but with a limit of 1A maximum.
