-----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.

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.

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)

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.
