ZZHXSM 12V To 5V Converter – DC-DC Step-Down Module With Micro USB Plug, 8-20V Input, 5V 3A 15W Output, Epoxy-Sealed Waterproof, For Ring Alarm Keypad And USB Devices

About This Product

If you need to power a Micro USB device – like a phone, tablet, or specifically a Ring Alarm keypad – from a 12V source, this little converter module is exactly what you're looking for.
It takes DC voltage from 8 to 20 volts (so 12V systems are perfect) and steps it down to a steady 5V at 3 amps, which gives you 15 watts of power.

It's got a built-in Micro USB straight plug, so you can just plug it directly into your device without needing a separate cable.

This thing is built tough – it's epoxy-potted and fully enclosed in a waterproof housing, so it's protected against dust, moisture, shocks, and vibration.

It also comes with built-in overload, over-current, over-voltage, low-voltage, and overheat protection.
So you don't have to worry about frying your device or starting a fire if something goes wrong.

Whether you're wiring up a security keypad, powering a USB device in your car, or working on a custom electronics project, this converter is a small, affordable, and robust solution.
