DC 12V/24V to 5V USB C Step Down Converter Type-C Interface 5A 25W Waterproof Buck Module Power Adapter Compatible with Raspberry Pi 4, Cell Phones 1-Pack

I had put a USB port in my truck. Then I plugged my windshield camera into it. It lasted a day and stopped working. I realized that the camera didn't take 12V DC it was supposed to run on 5V DC and burned up. I got this and wired it into my fuse box (with another connector I got off Amazon) and run it straight to my new camera. Then you can run the cables cleanly into headliner seeing how it doesn't connect to a USB port in front where everyone can see. Highly recommend!

Been very reliable so far. Seems to be a quality item.

These work great for powering USB-C devices in the context of amateur radio: I can run them off the 12v power supply in my shack or from a 12v battery when I'm in the field.

Wired into my Harley. Works awesome and charge much faster they the battery drain

Item arrived new. I will use it with a small motorbike battery and drip-charger for power-out use. :)

Installation is easy - just provide a positive and ground from your rig's fuse box or nearby wiring harness, and you've immediately got a 5v USB-C source that you can use to power a phone or display of some kind (I'm using mine to power my wireless trailer camera that required a power port adapter - now my power port is free to use for something else). Great value, and feels rock solid - if any issues in the future, I'll update this review, but am really happy with the functionality so far!Has two mounting 'ears' that come in handy when wanting to secure this to the underside of the dash or other similar location.

This buck converter is not for Raspberry Pi 5 but it might work on Pi 4 if you set for low power mode in Raspi-config. Not sure how to find out if this converter can really do 25 watts but probably not. Pi 5 chokes on boot immediately. Connecting up the Pi 5 official power supply works fine. I want back and forth 10 times between the official Pi power supply and this one: official power supply boots every time, this power supply chokes every time.

Your locked to USB-C as the output but i see it as a plus, dont have to solder that bit on.Just bear that in mind when you buy this.Also this wont tell the RaspberryPi5 that it can use "big power mode". But you can safely tell the pi in raspi-config to ignore the limits and just pull what it can. I can power a touchscreen, usb3 stick and the pi5 with an active cooler all on this thing with no issue.Don't really feel any heat coming from it, and its an epoxy build so its going to have good water resistance and strength. Of course don't submerge.. the way the cables come out the epoxy means its not 100% water tight.12v-24v input means car usage is solid.still going strong 3 months now. Powering pi5 with active cooler, a usb wifi adapter, usb soundcard, and usb rca camera dongle, & usb touch screen.

It’s a 3A not 5A. Not good for Raspberry Pi

I bought 5 of these to use with Raspberry Pi 5 and they work well.

Je l'utilise pour alimenter un petit travel router, fonctionne bien
