12 and 24 Volt USB PCIe

[MartoenHamster]

Normally you expect 5V with USB, but recently I found a site who's claiming to sell a PCIe USB 12v and 24v card.

These cards allow USB speeds up to 480 Mbps and include over-current protection.

 

They designed their own connectors, but I feel like they are not safe, you can easily remove one of the small squares and you'll be able to plug it into the wrong connector.

 

 

Is this card even useful?

Who would want to buy such cards?

480 MBps is slow, there is 10 gigabit usb already so 1100 MBps

I know, just for reference.

It tells you in the article "Furthermore, with the help of appropriate cables, devices which require a power supply of 12 V or 24 V, e.g. barcode scanner or POS systems, can be connected and need no additional power supply."

It seems pretty pointless to me tbh

It's a nice concept. Basically they're trying to do PoE but over USB instead. PoU or PoUSB so to speak.

Although the idea is nice I don't see a large market for this. Most USB devices are near the user and so is an appropriate electrical socket.

 

If we're going to toy with an easily mistakable adapter that we shouldn't for the sake of elongating a power source to a USB adapter why not use a Ethernet cable? it'd have enough wires for power/data provided the data wires can handle the distance.

That thing is ancient. Used for POS.
