JZK 12V To 9V 3A DC-DC Converter – Waterproof Step-Down Power Module For Car Audio, Radio, LED Displays & More

About This Product

This little JZK power converter is super handy if you need to drop 12V down to a steady 9V for your car gadgets.
It takes input from 11V all the way up to 22V and gives you a clean 9V output at 3 amps, which is plenty for car radios, monitors, LED displays, or even small fans.
The conversion efficiency is rated at 95%, so you're not wasting much power as heat.

It's got a sealed waterproof plastic cover, so it holds up fine in damp environments, and it runs cool even under load.

The whole thing is tiny—just 46x27x14mm—with a 13cm cable attached, and it weighs next to nothing at 30g.
Plus, it's packed with safety features: over-current, over-voltage, short-circuit, and over-temperature protection with auto-recovery.

So you don't have to worry about frying your gear.

Use it in your car, on solar panels, industrial equipment, or even kids' ride-on toys.

Simple to wire up, tough, and reliable.

Definitely a solid buy if you're doing any low-voltage DIY projects.
