Klnuoxj 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

Powering a Raspberry Pi 5, from a 12v battery in a emcomm box. Works as expected.

This is great! I use this to essentially hard-wire a Raspberry Pi into a 12V camera system. It's current appears to be stable, and the USB-C plug works perfectly to power a Pi.

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.

Perfect solution when you only have 12V DC and need to power a USB 5V device. I have bought a few for projects and have been working almost a year without issues 24/7.

So far so good. I mounted them in my sailboat in parallel with some lights that were in place already. Nice addition to have usb c connector for phones ,tablets etc.

This adapter appears to be well made and carefully labeled, but the specifications say "25 watts" and "5 amps max" and I'm not getting anywhere that if I can believe the little USB tester I have (see photo). Granted, the output current is more than double what I got from a standard USB adapter (0.8 amps at 5 volts), but it's not nearly as much as claimed. To be fair, USB C PD is complicated and both devices must talk to each other and agree on voltage and current levels. My other charger will switch to 9 volts which results in considerably faster charging- this one does not. And not all cables will support this. I tried 3 different ones including a known high power cable. Test conditions: the load was a OnePlus 9g phone at 70% charge level and room temperature. The charger itself was cold (50 degrees F) because it had been installed on my motorcycle which was sitting outside.

Needed a drop down voltage from 12v to 5v 5a to run a RPi for a robot project. many converters do not have enough power to run an Rpi and the Pi will alert you that it does not have sufficient power. This converter never tripped the alert on the Pi. Bought two of them as they are heap and handy + they work.

Used for wiring in a phone charger on a permanent basis for a Jeep. Worked perfect

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
