eWINNER USB 2.0 to DC 5.5 x 2.1 mm Step-Up Power Cable with Right-Angle Barrel Plug and Built-In Short Circuit, Over Current and Reverse Polarity Protection - TQ-WFVQ-TMNS

Run DC-powered gadgets straight from a USB port with this eWINNER step-up power cable. A USB 2.0 Type-A plug draws 5 V from a USB power source, and the built-in converter steps it up for devices with a 5.5 x 2.1 mm barrel input, ending in a centre-positive right-angle plug that sits neatly against the device. The smart circuit adds reverse polarity, over current, over temperature and short circuit protection to help keep your equipment safe. It is handy for fans, table lamps, Bluetooth audio, wireless routers and speakers, especially when travelling or working away from a wall socket, so you can leave the bulky AC adapter at home. Simply plug in and power up. Please check that your device uses a 5.5 x 2.1 mm DC jack and matches the output before use.
