USB C OTG 18W

This item works perfectly on my Samsung S25 Ultra. I can power an RTL-SDR and charge my phone at the same time!

AWESOME IT WORKED WELL WITH MY SAMSUNG S22 ULTRA TO BACK UP ALL MY DATA GREAT PRODUCT

I purchased this for the PiKVM. The quality is great, works as expected, plus the soft material makes it a bit nicer, and price point is also good. Definitely recommend. If you are running into an issue where you are not getting any data flowing through, you need to make sure you are not using one of those in between power buttons. It's the extension piece that typically comes with the CanaKit that the power plugs into with the button. I spent hours trying to figure this out.

It works exactly as it should, enabling me to record audio directly to my phone's video through the connection with a usb mixer, and allowing me to keep it charged during longer recording sessions.

This cable does function and do what it claims to do...sort of. I can successfully plug it into a phone with a USB-C port on it, plug USB-PD power into the power-only USB-C socket, and plug a USB-A device into the USB-A socket, and actually have the phone charge while it's simultaneously talking to whatever the USB-A device happens to be (phone is in "OTG" / host role mode, but is sinking power). Which is exactly what I needed. BUT, as far as I can tell, this cable does NOT contain any kind of power regulation circuitry within it in order to keep the feed of power going to the USB-A device that's plugged into it at 5V. Several times I would try to use this, and the USB device (keyboard, disk, audio DAC, etc.) would work for a little bit and then suddenly stop, but the phone would keep charging. So I pulled out a USB power tester, plugged it into the USB-A socket in between it and the device in question, and discovered that the USB-A devices would stop working because the voltage would suddenly jump from 5V to 9V!!! Whenever the phone went into fast-charging mode, the USB-A device was getting directly exposed to the higher voltage & nothing seems to be stepping the power down to 5V! I'm extremely lucky that nothing of mine that I tested with ended up getting fried!! On top of that, the connector that plugs into the phone is itself flaky on mine. If I wiggle or bump that connection at all while it's in use even the slightest bit, the USB-A port loses power. I tried it with more than one phone/host and it did the same thing, so it wasn't the USB-C port on the phone itself. Straight trash; don't waste your time OR expose your equipment to this product.

Work very well but problem is that if you leave it plugged into the charger it burns itself out.

I am working on a Raspberry Pi project and needed to be able to use the USB functionality while still being able to power the device. I bought this so that I could connect it directly to my phone as well. It does the job. The power feeds just fine, the USB-C port fits nice and snug on all ends, I've been able to use this on all the devices with no issues with compatibility, and even the strength/toughness of the materials and braided lines are a huge plus, as it doesn't feel like a cheap plastic like others I've bought. Will definitely get this again if I need more or make it a standard of my project.

Port where charging power comes in gets HOT!
