I've noticed the readings seem a bit slow and not always accurate. When I compared it to my phone's app, the app showed 16 watts initially, dropping to 12 watts due to temperature, while this device consistently displayed a different value. This suggests it doesn't always reflect the most current power draw. Even with a slower charger, my voltage-based calculation indicated around 1 watt difference, which further highlights the discrepancy. While I wasn't expecting lab-level precision, I was hoping for readings that were closer to the actual power measurements.

Works well. Fits well. Please know that only Watts are displayed. This unit does not indicate voltage or amperage. The readings I observed were consistent with other test equipment. USB-C requires that both the input and output must be connected for the device to display a reading. If the display is blank when power and load are applied, flip the input cable upside-down.

You plug this thing between your charger and and you device (mine is USB-C to USB-C) and you read the power being transferred up to 100 watts. So easy and good quick check. Th units are small and you need to keep track of them.

This is a USB-C inline extension adapter that shows the wattage passing through it. That's what it does and it seems to be accurate. I have put them onto the ends of some of our charging cables just to see how much our equipment draws (or how much is being provided by the adapter) and it seems correct. Simple to use and do the job.

I don't believe you can place too much credence in the number you're given. But it will absolutely help you figure out how good cables and chargers are.Just find out how many watts your phone can take then you can check the watts with different combinations. I had cables that will only deliver 5 watts to my phone and some will do 15+. Old chargers can do only 5 watts.I recommend this with no reservations.

Know I can notice if a charger really stopped when battery fully charged or not. This shows me if any watt is being consumed.

My testing (see the attached pics) shows these little watt meters are reasonably accurate. and they cost less than 6 bucks apiece. I don't know how they can deliver these for that.

I got four of these, two of them bought more than six months ago and they are going strong. Recommended.

You can buy cables with a display like this already built into them. You can also get more fully featured devices that track total power delivered, track volts and amps as well as wattage, or have built-in adapters for the various flavors of USB.So why buy this instead? Basically, two reasons - most of the time you don't need to know or care how much power is going through your USB-C cable and bringing a cable that has this display built into it everywhere just means it is going to eventually break or fail. You can disconnect this little meter and leave it in a drawer until you actually need it. Second, if you ever do need this info when traveling, it is much smaller and lighter than a larger USB tester.Most of the world is happily oblivious of the wattage their USB devices pull 100% of the time. Unless you are an engineer or electronics hobbyist, you will only use a device like this (1) to test whether a cable is capable of handling higher wattage/charge speeds, or (2) see the rate at which your device is sucking down power. Neither of those things require knowing volts, amps or total power delivered over some period of time.It does have an indication for "PD" or the power delivery USB protocol that lights up when you are running higher wattage devices through it.I tested it against another meter and the wattage shown seemed basically accurate. This isn't a piece of scientific equipment, but it seems accurate enough for the intended purpose. I also connected it to a USB-A device using an adapter plug and it worked, so you can use it to measure the power draw from older devices if you already have an appropriate adapter (it does not come with one).I have not owned it long enough to comment on durability. I'd expect it will eventually die if you carry it around everywhere, but it seems adequate for the occasional use it is designed for.

-----toocki USB C Adapter, 2Pack 100W USB C Female to USB C Male Extension Adapter-----I can say, I am not dissatisfied with your product. You have a happy customer. I have used it to test various cables and chargers and a mixture and combination of.... it's interesting how the different combinations will change the charge rate of devices.I can match and pair my chargers , cables, and devices for what works best for each. With one cable and one charger when used with one device, I can get 15W, but if I use that same cable, same charger, on a different device, it may only get 3W, change the cable, get 8 watts. different charger, 12W . Explains a lot of the issues I was having with a tablet. I have one dedicated to my vehicle and use it daily, gets plugged in and unplugged quite often as I'm in and out of the vehicle. So the durability seems quite well. I've been able to read the screen in most daylight conditions, in the vehicle. No issues with the screen. We've had a few warm days, but we will see if it can survive a summer inside the vehicle, as it gets pretty warm here. I think y'all have done a decent job with these. If I have a use for more, or lose one of these, as they are small, but that is a GOOD thing...lol. I like the size, it's not obtrusive or difficult to handle, I would absolutely purchase again.

This one is a great product, what can I say. I gave it 4 because it doesn't display 100W, my portable charger will charge up to 100W maybe because of some electrical losses
