SZRMCC USB C Type-C to DC 5.5x2.5mm 12V PD Trigger Power Cable for KiPRO LCD Monitors cine Broadcast Radio Any 12V Device

Last summer, we had a major storm. And and thousands of other customers lost power. I was out of 5 days.I work 100% remote now. So I wanted a way to power my cable modem / router, in the event of a power outage.I used this cable with a plug in style USB C power bank made by a company that rhymes with banker. The power bank has a 10,000 milliamp battery. I tested the draw of my router, and it was no more than 200 miliamps. This would give me about 50 hours of run time.Of course, my laptop battery wouldn't last that long. And this also assumes that my ISP is still up. But I dig it.Last caveat, the battery bank doesn't instantaneously switch from wall power to battery power. It takes about 1 second. Which means, your cable modem / router will reboot. Which means it will take a minute or 2 to get back up. And your VPN tunnel will have been severed. You'll have to reconnect. But you're only looking at a few minutes down time.

The cable is advertised as having a 12v PD trigger, which is only true if your source battery or power supply supports the deprecated USB-PD 1.0 profiles. Most modern power packs will only support USB-PD 2.0, 3.0, and possibly 3.1. This cable will trigger a 9V profile on a USB-PD 2.0-3.1 compliant source; if you need 12v, you need to make very sure you have a compatible legacy source.Otherwise, you will need to find a cable that has a power inverter in it that will regulate either the 15v or 20v profiles from a USB-PD 2.0-3.1 device. There may also be a buck/boost version somewhere that will give you 12v from the 9v profile as well, but this is not recommended.To confuse all this, the cable is labeled as USB-PD 3.0, which again does not support a 12v power delivery profile.

I purchased this cable to extract 12v from a pd battery pack for use with my Einscan 3D scanner. It outputs a tiny bit over 12v, so this is working as advertised. I'm using a battery pack that's able to output 12v and if yours is outputting a different voltage then it's because your supply does not support the 12v trigger. In terms of the build quality, it's very good and the connectors do not feel flimsy. One thing I appreciate is that it arrived in a coil vs folded up like some other cables.

This is one of the most solid build options for a USB-C to DC 12v. Other ones are noticeably cheaply made which is not what you want when powering expensive equipment. I've used this for everything from routers to a Celeron N5105 powered mini PC.One things to know is that NOT ALL USB-C CHARGERS SUPPORT 12v outputs!! Check your charger first as they will list all the output voltages such as 5v, 9v, 12v, 15v, and 20v. Many many chargers will support 5v, 9v, and 15v only so you may damage your device by supplying the incorrect voltage so check the charger first!
