Absolute genius! This adaptor provides you with 12V output from a common USB socket (usually 5V output). Useful for powering all sorts of 12V devices direct from a computer or other USB charging source such as a battery bank. 12V @ 1A rated output when connected to a high power USB outlet. Includes 7 standard DC tips to suit your device.
 
Note: Your USB port must be equipped for high current (2.1A or greater). Some USB ports (particularly those on some computers) are 500mA rated. The device will work perfectly, but will not be able to provide the full 1A current at 12V if connected to a low power USB socket.

Great product

ChihuahuaJuly 2025

It’s a great little dongle I use it to power my 12v lights when the 12v socket in the car is oqupied but something funny is that in the discription it says that the cable lanth is 500m

Works great, but...

Bought this to run a 120mm 12V 380mA computer fan. It does the job well, however the USB itself gets extremely hot during operation, hot enough to where I'm concerned if somethings wrong with it. I dunno if there's some sort of short inside but it still runs the 12v fan just fine.
