Customer Reviews (4.8 / 5 · 5 reviews)

Chloe ★★★★★

I was pleasantly surprised this little cable actually delivers a steady 12V—my old webcam that kept dropping out is now working perfectly. The step-up converter is neatly built into the cable itself, so there's no bulky extra box to hide behind the desk.

James ★★★★★

I've been using this to power a small LED strip that needs 12V, and it works perfectly straight from my laptop's USB port. The built-in step-up converter is impressively compact and doesn't get hot at all.

Claire D. ★★★★★

Plugged this into a USB power bank to run an old router during a power cut, and it worked perfectly. The 12V output is stable and the built-in converter means no extra bulky adapter needed. Really handy for powering small devices away from a wall outlet.
