2-Pack 12V 24V DC to Dual 5V USB Female DC Converter Adapter Step-Down Buck Module

Who doesn’t like a solid performing power supply? These are sold as a pair and work exactly as described. I keep a security panel on back up power and feed that power with one of these. USB is snug and fits perfect. I recommend this product.

I use these to connect my phone chargers and Bluetooth adapters under the dash of my car. It cleans the dash up nicely.

I have a coat closet that needed lights but no electricity anywhere near it. It did have a landline phone connection for outside the closet. I cut in a connection into the closet, connected one of these, put in a motion activated LED strip light and Presto I now have lights in the closet...

Use these to power USB items, for example a GPS, on both cars and motorcycles. They have served well over the hears.

If you are expecting 3amp at 5v on your vehicle, it does not output that. I used to for wiring on a wireless charger and found that the output amperage is not high enough to keep the phone charging while using navigation. At least not with the wireless charger. Upon checking the other open USB port, I see ~1.8amp. Seems like this would be a decent current for charging but it appears the wireless charger needs more juice. Everyone should be aware before purchasing.

Runs my pi 4 on my 3d printer just fine. Just make sure dont plug it in backwards or it will send 24v to you 5v line and crispy everything plugged into it. It's nice there are two.

I bought the 2-pack, figuring I'd have a spare if I ever needed it. Well, the first unit broke after 5 weeks. This was just one week after the return period was over. So, I put in the one I had bought as a spare. This one turned out to be DOA...dead on arrival. I would recommend trying another vendor as these are just junk.

Going camping and need a USB to charge things? This works great!
