What is Reddit's opinion of DC-DC 12V to 5V 3A Micro USB Converter Voltage Step Down Regulator Waterproof Power Converters for Car Smartphone?

From 3.5 billion Reddit comments

I don't see why not. You have ground (black) and 12V (red). Take a multimeter and assure that you are getting power, and that it is indeed DC (AC should measure 0, and DC should measure 12).

Next you will need a 12V to 5V adapter (you don't want to power your iPad with 12V):

So, with the adapter, an iPad charging cable, and a bit of wiring and luck, you should be all set.

I used something like this on my Classic. I just went to the fuse box and found the one that came on with the ignition. It's plenty long enough to reach from the fusebox to the handlebars.

Something like this maybe?

Thats just an example but they make them for various input voltages, and its pretty simple to make your own as well. You could do 24v to 5v for example since you already have 24v.

It would be handy for making charging points for your tablets powered fromthe utility room.

Recently used a buck converter and tested /wired a Pi 3 / 4 8GB to a car battery. My gosh, between the pi’s very specific power requirements and the cheap buck converters out there it took me a while to fine a working converter. Here’s the one I used. When adding to the Pi 4, it actually went to a PiJuice (so not usb-c).

I appreciate your help, and yes, I actually bought 2 12v to 5.5v micro USB modules (https://www.amazon.com/gp/product/B07H7X37T6/ref=crt\_ewc\_title\_huc\_1?ie=UTF8&psc=1&smid=A36ZH2MCHPKXUA) so that I can step the power down to the Pico. I am going to read the voltage coming out to the lights, because that's a good point, the Pico may not have enough output wattage to cover what's needed to make them as bright as they should be. Do you know how much output voltage you can get from the pin from the Pico?

Also, I fancy a 3D printer myself, but I can only print PLA right now, which may be enough to create a nice box for it, but I may need to add some kind of epoxy to the box to make it not leak with water, etc. Unless you can print ABS, then I would take you up on that offer.

I have mine hardwired into power circuits that come on when the key is on. So my front cam is hardwired to the power feed for my auto-dimming mirror, and my rear cam is wired to the power feed for my rear wiper motor. I use small 12V-5V DCDC converters (These ones from Amazon) and just run the cable out from under the headliner to the cam!

​

Edit to add: You only need a power source in the rear if you use two separate cams like me. If you use a dual cam it gets its power from the front.

Hello! I've recently started making myself a small hobby budget laptop with a raspberry pie. Thus far I have a keyboard, mouse, housing, and Raspberry Pi 3B+. I'm in Canada.
I'm now looking for a display that I can simply plug into my 3B+ and hook along my housing to finish my build. The issue is, I want to make sure that my display and pi are running through only a single power cord. That means when I plug it into an outlet, the laptop AND monitor will turn on.
This has lead to a crazy headache. I don't want touch screen, as I'd never use it and it bumps the cost of the official 7" display up to a whopping $100 with shipping, literally quadrupling my initial costs.
So naturally I decided I'd find a simple HDMI Display and buy a splitter that steps the voltage of the power supply down and splits it between the two units. The issue with this, and what's giving me the BIGGEST HEADACHE OF ALL TIME is the fact that the resources on how to do this are weighed down so thoroughly with meaningless nomenclature that I am totally lost in figuring out what to buy.
Do I buy a 12v power supply and a DC-DC 12V to 5V 3A splitter and fuck around and find out with a thrift shop monitor?
Is there no budget option display that I can literally just plug into my pi without spending $100??
If not, will the below links work for my needs??

Please help, I have a headache.

12v to USB 5v is one of the easiest things to find.
