toocki USB C Adapter, 2-Pack 100W Female to Male Extension with Power Meter Tester & Digital Display for iPad Pro, iPhone 16/15 Pro Max, MacBook Pro, Laptop (Grey)

-----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 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.

Very neat little devices. Let's me see at a glance just how much it is pulling from the battery without the need of a high powered USB diagnostic setup. LED is surprisingly bright and you will not want to sleep with it on the charging cable. Only caveat is that the construction makes it easy to pull too hard and the cover will slide off. When this happens the transparent plate for the LED comes off completely. You will to carefully epoxy it back together. For your money though, you will be hard pressed to find a better device to tell you how fast your device is charging. Very satisfied with the performance.

Let's be honest, you almost surely do not need this. I have been going through my cables to get rid of the ones that have lower charging capacity and before this came I was testing it with my laptop and making pretty quick work of it. That said, I enjoyed having this item. I was a bit bummed that it seems to max out at 100 watts, but my computer did detect it was charging at 140 watts despite it only reading 100 watts. One thing that I do like is I think this gives a more real-time measurement, and honestly more accurate, estimate of the charging rate than my laptop was showing. The laptop would show the maximum speed it was able to get, but it did not account for charging rate slowing down as the battery filled up, which this device was able to detect. It is small and easy to include in your backpack without any problem and feels like it is of high quality. The screen on it is clear and easy to read. Overall, I am very glad to have it, I just wish it read above 100 watts, but for the price I think it is a solid value.

Works as expected

My initial purchase was idle curiosity. Here was a way to see the charge rate of various devices. But I quickly discovered that when my tablet was fully charged, the display would turn off. Not having an LED on the tablet that showed status, the only way to know if it was finished was to open the cover and tap the screen then wait for it to show a display of charge state. With this adapter plugged in I can easily see if the display is on or off from across the room. Very handy when you have multiple devices rotating on and off various chargers around the house.

I like knowing how fast a device is charging, and these allow you to use any usb-c cable to do so. My only complaint is that the display is not bright enough to see easily in daylight, and I use this in my car. I have cables with the display built in that are much brighter. If you only plan to use these indoors it shouldn't be a problem.

Great product to test chargers and cables. I recommend it.

EDIT: Customer service reached out to me to make sure everything was taken care of. So I had to give 5 stars for integrity. Regardless here were my test results. Using a test bench of 100W Power block, 100W and 15W Power Bank, 15W and 18W Power hub. Performance is as follows: 100W Power block to Device - Worst offender, will often cause the device to stop charging, but when it does work it jumps around a lot but will give you accurate max. 100W Power Bank to Device - Same problem but with a 10 second delay. 100W Power block to 100W Power Bank - Same issues but much less prevalent (every few minutes) 15W USB Hub: Accurate works but struggles to post lows when reaching 1-5 Watts. 18W USB Hub: Same issue as 15W Hub. 15W Power Bank: Consistent. Stays accurate and never powers off. In summary what is this used for? Testing for underperforming cables (Yes) Confirming Adapter Power Range (Yes) Low wattage devices functionality (Yes but above 15W) For Fun (Yes) Testing High Power Devices for consistency (No) Testing low power Devices for consistency (No) For 24/7 display (No)

Cumplen su función, si miden bien o no es muy complicado confirmar, pero trabajan bien, recomendado!!!

Useful to confirm power draw and the amount. Doesn’t work with the OnePlus fast charger, it just flickers or goes dark and the phone doesn’t charge.

I love these. You can see how your recharging is (or isn't) going, Wlee made and well designed. I have bought a few

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.
