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

Exactly what I needed to replace the 45W power supply used for Acer Aspire3 w: 3mmx1mm plug connector. Small in size and covers multiple voltages. In my case using the 20V output from a 45W or 65W usb-c power brick. Positives: - Comes with 10 adapters which allows for multiple devices - Voltage is selectable which is good if you know what voltage your device needs - Compact size - Works on any laptop with the compatible plug What you should know: 1- Note that this device is merely signaling the upstream USB-C port to provide the selected voltage. It is not up/downscaling the voltage itself so you do need a usb-c power brick that can take multiple voltages 2- since the selection is manual and it defaults to 5V, it’s probably good for travel but not for it to always be connected since it could unintentionally reset to an incorrect voltage 3- works on microusb and usb-c devices but again you need to set the correct voltage. it’s too bad it can’t auto detect

The USB to barrel adapters work great. With a USB A to C adapter, I was able to power up a 5V camera I frequently move around with a battery bank instead of a wall outlet. I didn't have a USB-C battery bank, so I used a Anker PD wall charger block to charge a 12V pump. I had adapters from another set and was about to use alligator clips to power up 9V devices. I was not any too test 15V or 20V devices. Would be nice if it included an adapter to reverse the polarity and USB C to A adapter.

TL;DR: Quality adapters with handy voltage display, user diligence required, laptop compatibility hiccup, successful diffuser test, future potential use. These adapters are like the trusty sidekicks in the world of gadget connectivity – they do their job and do it well. The standout feature? The built-in voltage display, which feels like having a mini tech genie telling you everything's in check. But, as with any tech tale, there's a twist. The mantra of "know what you're buying" rings truer than ever here. In my quest to power up my laptop via my battery bank, I stumbled. I overlooked my laptop's battery specs, leading to an anticlimactic non-starter when the cable and laptop first met. A classic case of user error, a reminder that in the tech world, it's always "measure twice, cut once." Not one to admit defeat, I tested these adapters on a small air diffuser, and voilà – success! They powered it up without a hitch. Sure, I don't need these adapters for my diffuser, but it's reassuring to know they work. So now, these adapters are like those extra buttons you get with a new coat – not needed right now, but potentially lifesavers down the road. They might be lying in wait for now, but I'm keeping them close – you never know when tech destiny might call.

got this to add to my electronics kit so I could test various devices to see if they are working without having to have a ton of different cables, first thing I used it on was a monitor my buddy found by the dumpster at his apartment, the thing had odd power requirements but this thing worked fantastic to power it up. the monitor was broken unfortunately but thanks to this guy we were able to see the original owner smashed the screen

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.

cumple con lo que promete.

I’ve been using this product for a few weeks now and I’m genuinely impressed with its performance and quality. The build is solid, it works exactly as advertised, and the setup was quick and hassle-free. The value for the price is outstanding, making it a smart choice for anyone looking to upgrade their toolkit or start a new project. I’ve tested it in multiple scenarios, and it consistently delivers great results. Whether for a hobby project or a more professional setup, it has earned a permanent spot in my collection. Highly recommend for its reliability, ease of use, and excellent value!

المنتج جيد ومطابق للوصف

This cable is awesome, many fitting, selectable voltage up to 20v.

This thing is really cool, It powers most of all my 6/12/14v devices often proving 12v @2amp consistently on such electronics like a raspberry pi to a network switch. Of course there's limitations but I run most of this from a high output battery bank and it's worked well for what I needed l, exceeding my expectations.
