USB C to DC 5.5mm x 2.1mm Power Cable Cord, USB C Input to DC 12V Out Charging Cable, Work with PD Charger and PD Power Bank, Output DC 12V 3A MAX 36W

Works good. And arrive fast

I thought I was buying this on a whim, for "old stuff" to go on my desk, but during setup I found that a desk-lamp I was planning to use wouldn't turn on. Quickly debugged it to a dead power-supply, and this cable allowed me to just plug it into a USB-C charger instead. Works great, my desk-lamp is fine, and I trust the charger's safety more than the old outlet which came with my lamp. These cables are a great idea and mine seems to be working well, albeit only a day old. Get rid of your old AC/DC adapters, use modern GaN converters with better safety margins _and_ reduce cables to your desktop, use a cable like this to fit older kit into modern power delivery.

I ordered one of these cables and when it came, it wouldn’t power up my RV backup camera which requires 12V so I measured the output from the new cable and it was only 9V. I returned that cable because I thought maybe it was just defective and ordered a direct replacement which came and I tried it today, with the exact same results. The cable is only putting out 9V not 12V like it says in the description and like the label directly attached to the cable says.

Perfect! I got this for my little LZSIG audio mixer to eliminate the power brick and reduce audio noise (the mixer's supplied brick doesn't the best filter). It works perfectly, and the clean power from my USB power center has eliminated the buzz. The cable is short, which is just right for my needs as it isn't dangling all over the place. A note for if you're comparison-shopping: USB-C power supplies can provide 12V power as part of the USB-C spec; no conversion circuit should be necessary in this type of adapter! This particular adapter gets it right, so it's up to your power brick to deliver a good 12V output.

This device will give you 12V DC from an appropriate power supply... sometimes. I had a devil of a time getting this to work. When I left this power cable cord attached, and turned on the power supply, it refused to negotiate 12V. 5VDC would be what I got, which is native to the power bank I was using. It turned out I needed to turn on the power supply FIRST, then plug in this power cable cord. Even then it would not always negotiate 12VDC - I quite often got 5VDC. I bought this as a backup for a cable I already use, because I can't afford to be without one when I'm using it. This power cable cord isn't dependable enough to me for me to recommend it.

12V Out charging cable reviewed here : Cable seems to be well constructed, and yes, the wire length is short, just over 3 feet. I have tested the unit on several batteries and PD chargers, and found that the on-board chip will negotiate UP TO 12V and provide that voltage to the barrel connector. This means that if your PD Source supports 5V and 9V, the unit will provide 9 Volts. If your PD Source only supports 5V, you will get 5 Volts. You could end up Under Voltaging your devices. This may not be a problem for some devices, but can cause others to overheat - yes, under-voltaging causes overheating. Lower voltage causes higher current draw, which can damage your electronics. The manufacturer should have either made the unit ONLY send 12V, or noted clearly on the documentation that it will provide UP TO 12V (Oh, wait, no docs came with the unit) Please use this with care with untested PD Sources, you might end up frying your equipment! Stay safe.

My goal in purchasing this was to power an amateur radio off the Anker power Bank I already have. Maybe this thing's 9v and the 9v needed are just slightly too different but that's my problem not this cable's. My power Bank says it will output 9-12 V and at the business end of this cable I was measuring 9.1v with a multimeter. I'm absolutely keeping this around tho because this could be real useful with something that is less picky with how it's power gets fed.

I purchased two of these to run my wireless routers. Both cables worked perfectly with PD capable wall chargers and battery packs. The standard connection fit perfectly. I did not get to test the adapters since I did not need them. For what I needed these are good quality USB C (PD) to 12 volt and worth the price.
