USB C to DC 5.5mm x 2.1mm Power Cord, USB Type C Input to DC 12V Out Charging Cable, Work with PD Charger and PD Power Bank.Output DC 12V 3A Max. Portable for Outdoor Test, Studio and Travel.

I enjoy using my Masterbuilt 560 gravity smoker, but don't enjoy dragging out an extension cord every time I want to cook. It's unsightly, a trip hazard, and just an extra step from finished food. Additionally, the strain relief for the controller's power cable is non-existent. This can cause the cable to be damaged over time. This adapter can be used to power the smoker using portable charger instead. You want one that supports USB-PD12V 1.5A for it to work properly. This setup works great and addresses all the issues I had with plugging the smoker into the wall. If you don't use a battery than supports 12V, it'll output 9V instead. Also, try flipping the USB-C end of the cable. My battery supports 12V but only in one orientation apparently. Annoying but manageable.

After trying 2 other similar cables this one finally worked as advertised. Ensure your power source is USB-C PD and capable of 12V DC output. The cable has a chip that requests 12V from the source via PD protocol and seems to work great so far. It's about 3ft in length so a good size. Would have been nice to see 2ft versions as well tho for more versatility.

This was purchased to put another Power Bank to a USB C connection of a SBC. It worked well and it still works.

I get so tired of buying and returning products when they don't even meet the most basic claims. It seems all these products just put whatever together and let you deal with it, hoping you're too lazy to return. This product, specifically says it has a 5521 or 5.5mm outside diameter with a 2.1mm pin diameter connector on it. It doesn't. It has a 5525 or a 2.5mm pin diameter connector. While it may physically fit because 2.5mm is bigger than 2.1mm, it isn't 5521. Unlike many 5525 products which I've used which will work reliably with both because they use bendy pin contacts which will actually fit both, this one doesn't. I was going crazy thinking my devices were going bad with random restarts/turning off when it's just the horrible connection of this product. In sharp contrast, I've bought about ten of the GINTOOYUN version of this (https://amzn.to/48ntP3F) which comes in 9V, 12V, 15V, and 20V versions. Those are real 5521 connectors, and they work flawlessly. They solved all the flaky problems that I was having with this Tpenod cable. Finally, note that almost all of these types of products say they are limited to 3A. The reality is that the E-marker chips they use advertise 5A. So, you really should not use USB PD chargers over 60W. The reality is that (check the manufacturer specs) you can use about any USB PD charger for any voltage except 20V since that is typically the only PD voltage node that USB chargers put out 5A. For example, I've never seen a 15V 5A USB PD output. Or, make sure that the device you're using doesn't draw more than 3A. Another final caveat is that not all USB chargers support 12V PD output which is a holdover from PD1.0. Sadly, newer products from Anker do NOT. Most others do, although I recommend a quality USB charger since I've run across a lot of garbage USB chargers over the last few months. I am currently using a lot of these OTAO 200W USB chargers with a wonderful display: https://amzn.to/42I8lNP and a lot of these AOHi 65W single-port cube USB chargers: https://amzn.to/4bINrlB which also come with a USB cable with an LED display in them. Yah, I don't trust anything anymore. 80% of products don't work.

I use this cable in reverse to the way described. I have a 12v supply with barrel jack on my Mini UPS, and I use it to supply 12V into my travel router via USB-C. It works just fine.
