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)

They do exactly what there intended to do and there acurate. Difficult to see outside in the sunlight as there not very bright. However they do the job and seem sturdy.

The USB C wattage meter in this USB C add on plug delivers accurate wattage transfer speeds. in a convenient, reliable form that confirms (or exposes) marketing claims about straightforward Watt transfer speeds for any usb cable. The wellmade usb female to male extension plug offers nothing more or less when verifying speeds up tp 100 watts.For $10, it is a great bargain and recommended.

the adapters work great and show the correct charge info. they are of good build quality and haven't had any issues yet.had one unit stop working but the company refunded for the unit and took care of any issues.would buy again when needed and recommend.

-----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.

Interesting to know how my device is pulling power, how much, and what protocol. They are small and easily connect to my cable and the device.To the manufacturer... on my laptop with the USB-C port on the left side, the display is reversed. It would be a great upgrade to this to somehow flipping the display around for left hand connections. Also, the display could be a smidge brighter but it is otherwise very readable.

Two power meters adapters that are USB C female to USB C male, allowing you to put them on an existing USB C cable to add the power meter function. The adapters have a metal shell and are relatively small (although they still may be large enough to cause some problems when plugging into a phone that is in a case.) Pretty simple to use, just attach to a USB C connector on a cable and you get a display of wattage draw. They came with no instructions or specifications, but do seem to work well.

These USB-C power indicators simply plug in line with a USB-C power cable. There is no set up or programming. Just read the indicated charge wattage on the digital display. The displayed power digits are very small and very dim, making reading the wattage value challenging. I have only tested them on typical small, less than 15W loads so far.

Easy to read and very useful. 4 out of 5 only because they are rather cheaply made and kinda flimsy feeling. Having said that, they haven't broken yet! So far so good

USB C Adapter, 2Pack 100W USB C Female to USB C Male Extension Adapter Type C Power Meter.These little items are very handy to have on hand when you are charging items. They let you know that there is power getting to your charging items, and when they are charged. HAPPY CUSTOMER.

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

All good. Works as described.

I used this to try and see how much power my charging bank could take. When I plugged this into the power bank using a known good cable, it fried the power bank and caused it to smoke. Power bank was a good Aukey pb-wl03 20000mah.. Very frustrated that something like this could cause so much damage immediately. Am sure they won't honour any sort of warranty on this so I am going to return it and at least recoop my costs on this sketchy power meter.

The male end has little plastic covers that need to be removed before using. When not in use, re-cover the male end to keep dust and dirt out !These are a lot smaller than the seller pics would imply. Each is 1.5" long and .5" wide. Inserting them into my cell requires a bit more force than is used when inserting the charging plug. Once in, they are in there firmly.My test cell phone is rated at 15W (up to 25W quick charging, depending on the adapter used). As you can see, it is only charging at 8W but that might be because this cell is 5 yr old so the battery may be/is degrading.Charging rate will also vary depending on current status of battery you are charging- - for example when nearly empty your charger charges at full power. As it nears completion, your appliance (cell phone for example) reduces the wattage to protect the battery. My nearly depleted tablet battery charged at 14w fast charge (limited to 15w) but when it got to ~90% it was being charged at 2w per this measuring device. Perfect !Both of the units work straight out of the box. No instructions provided OR needed.I measured my slightly newer tablet and it is also rated at 15W. It measures 13-14w .I tried to measure the W while charging a portable battery pack. It did not work. Maybe it's not supposed to be able to. I thought it should. I am not deducting any * because I don't have an answer for this test result.I find both of these function properly and measure like they are supposed to.Upped to 5 * .
