To power your 5V DC devices from any powered USB port, all you need to do is check your device required 500mA or less, and it has a 5.5mm plug barrel socket!
Sick of all those big power transformers hogging a socket on your powerboard just to charge a phone dock or run a tiny video converter? Well, now you have the option to power those devices via USB! Any small electronic device which can accept a 5.5mm Barrel Plug and runs of 5V / 500mA power is suitable for connection to a USB socket using this cable.
On one end of the cable is a regular Type A USB plug, suitable for use in any powered USB socket on a wall charger, computer or even your TV. On the other, you have a hollod-pin power plug with an external diameter of 5.5mm, an internal diameter of 2.1mm and a contact length of 9mm.
A great option for installing small electronics in caravans where 240v power sockets aren't availble.
Voltage Compatibility: Many large and multi-output home theatre electronics require 12V or higher voltage to operate. This cable is only suitable for DC 5v electronics accepting the 5.5mm diameter plug. Check your device's power pack or manual to ensure it accepts 5 volt power.
USB Source Compatibility: Please note that many mobile devices - including laptops, tablets and smartphones - do not output the enough power over USB to power some devices due to their extreme power-saving measures. We recommend USB power sources including Desktop PCs, USB Wall Charging Outlets, and USB Ports found on TVs.
