FARSENSE USB C to DC Adapter,Barrel PD Trigger Cable(3.3ft) with 10 Connector Tips,USB to DC Power Cable can Switch Voltage by Pressing The Key,Support LED Display Voltage

This is a handy little cable that allowed me to replace a cumbersome wall adapter for a 12V 5.5mm plug with this, which just plugs into my existing USB-C adapter.Since this cable uses the PD standard to access voltages, you do have to be careful about which adapter you use it with. If your USB adapter doesn't support the 12V PD, then this cable won't be able to output 12V. This is especially frustrating as many charger bricks for sale online can be a bit ambiguous about whether or not they do, or on what precise ports they support 12V PD. So be careful with that.

This is likely the best cable I have ever owned, like seriously, it works just for about everything, I have not encountered a thing it would not work on, I needed this a lot back in 2016-2019 when USB C was becoming mainstream but this didn't exist exactly like this, nowadays it's a wonder, I can use my high power rated Power Bank to turn on most things.Thank you!

This adapter works great! I'm using a Ugreen 65W brick on it, and it cycles easily through all the available voltages. I was able to confirm them all with my multimeter as well.If I have one gripe, it's that there's no marking for what polarity the barrel plug is. It's positive tip, for the record. It would be nice if they included a polarity reversing adapter in the package since not every device is wired for positive tip. Depending on the device, you could damage something if you plug a postive tip barrel into a negative tip jack.There are plenty of these available on Amazon, so getting one isn't a huge issue, but it would be nice as a pack-in.Rating this four stars. It loses a star for the lack of polarity markings and not having a way to reverse it.

This thing is absolutely incredible. I lost my charger for an Acer Aspire 5 that came with a 65 watt charger. I purchased a replacement and the thing wouldn't fit even though it said it was compatible. So I decided to try this even though it's so tiny. I am blown away that it is literally charging my laptop as we speak with this tiny little device set at 20v. The laptop requires 19v to charge but 20v is not a huge difference or I would be concerned. Plus a lot of times you can have some voltage drop anyways. It is constantly charging at 45w which seems okay considering I can use the laptop and the percentage does not ever drop and continues to go up. I have used this to power a router, a laptop, a battery charger, a Sony PSP, my Pixel 6 phone and it just works. It's not the ideal charger for a phone because it won't detect that and I believe the other cables lets the phone acknowledge the fast charging. It's still charges at over 14w and actually close to a powerful cable I have which is surprising considering the phone does not display nor know of its capabilities. That to me is not a big deal because I don't use this to charge my phone and just did it as a test. I believe it just pulls the power from two cables or maybe I'm wrong but it seems to be a simple DC boost converter in a way. I am actually feeling the thing right now and it's not even that warm and definitely not hot even with it pulling 2.1A at 20v for the laptop. I just thought it would get hot because it's so small. I want to try and see if I can power even more powerful things, but my next powerful unit would be a laptop that requires way too much power at 230w so that would certainly destroy it or maybe it has a protection circuit because I did see it has error codes. I highly recommend you buy one of these for those emergency situations or just because you need something like this in your arsenal of tech goodies. I am going to buy another but it is listed in another place on Amazon for a couple dollars less so that's good. I am highly satisfied and I believe you will be too. You just got to get used to how it functions and the directions were well written enough where I could understand it very easily. This is one of the only cables I have seen like this ever. All the other ones are much larger or are straight usb cables with barrel adapters but those do not have any protection nor do they do any boost. It doesn't matter how this works as long as it works and it does. Just buy it and you won't regret it!

This is the worst product I have ever received on Amazon. The USB C connector was loose in all of my battery banks. It throws error codes when you use usb a adapter. I immediately returned.

This basically does what it’s supposed to, but the main problem with it is that you can’t get it to retain its power setting. This can be a problem in any case where the usb power supply might shut off and come back on.I got this primarily to test USB chargers and power banks with an electronic load tester. It’s not very good for this purpose because of the fact that power can get interrupted (by overcurrent protection in the supply during testing, for example) and having it reset to 5V every single time is extremely annoying.Switching voltages is also just not implemented too well. For example, you hold the button down and nothing happens until you release it. So initially you wonder just how long you need to hold it down. Errors are not very descriptive and only indicate that it failed to negotiate a specific voltage but not anything about why.I was also not able to get more than 70W through this cable at 20V, and it does seem a bit too thin to be a USB PD 5A (5 amp x 20V = 100W) cable. USB PD SPR (“Standard Power Range”) cables need to be able to handle 5A, rather than just over 3A like the 60-65W cables (3A x 20V = 60W). The fact that I can only get 70W max through this makes me think it’s supposed to be a 65W cable.But I can’t get an e-mark tag response from the cable so it isn’t even claiming to support anything like it should be if it’s USB-C compliant.I suppose there will eventually be competing products and this one will probably get improved, but for now this one is kind of half implemented and I’d recommend using a more reliable trigger module for anything important.

Cool device, allows you to run pure dc out if your powerbank to power dc devices, effectively replacing their powerbricks w/ this. Everyone needs one of these in their gear bag at the very least.

Super cool to power 12v stuff with my USB-C power bank!
