Handy to check how much power a USB device is consuming, but when combined with a wall adapter, this little thing can even be used to see if a wall outlet is able to pump out at least enough proper power for standard USB power (5V === 1A) if not more (since USB-C supports higher amounts of power) as well as just see how much power something like a power bank or my iPad can output. Really, it's just fun to test it out with different stuff to see what readings you get.

This has proved to be insightful in monitoring both problematic USB devices, and interesting to watch whilst using/charging other USB devices. I haven’t found anything it doesn’t work with yet.

Absolutely inaccurate. iPhone 15 Pro Max shows charging at 4.18 Watts. Laptop capable of charging through USB-C at up to 100W - shows charging at 5.35 Watts.

Very cool little device lets you know how your chargers ACTUALLY perform, nevermind the claims on the box. It also shows you how well your device is taking a charge. I absolutely love this thing.

TL; DR: well built unit good to look at charging processes only. cannot be used inline with a data device.The unit is a well-built small dongle with a bright screen that is very legible. The typeface used is small, but this is inevitable due to the small screen size. It does what the listing shows.However, when connected, data does not seem to flow in either directions, or if it does, something is preventing establishing a reliable connection. This means that you cannot monitor USB SSD drives, or check how the PD function of USB docking station really works, because the laptop cannot access any of the devices connected to the dock -- and therefore cannot be monitored while using such devices.I did not expect the device to provide any information regarding data flows; such functions are not in the specs after all. However, I did not expect that the unit would interfere with data communications.Bottom line: great unit to monitor the charging function of a device... but that's it.

This is about as simple as it gets. Plug the monitor inline with your device and see how much power you're using in watts, amps, and volts upto 240 watts (the current maximum). Cumulative energy delivered in watt hours is also displayed. This information can be used to verify that your cell phone is charging at its maximum rate, or that your power supply is providing enough power for your computer to charge. If the display is off, no power is present. Did you plug in your power supply? Is it broken? Is the cable good? These questions can be answered with this simple device. It comes in a nice tin box for easy storage and protection.

I REALLY like this little meter. Accurate enough for what I want, which is to just generally see what's going on with my devices/cables. This is plug-and-play - no settings to adjust but rather a simple power monitor. Form factor and cosmetics are great - but note this is a SMALL device, and along with it a small (but really nice) display.Build quality and fitment are excellent. Has a solid feel and some weight to it. The IPS display is bright with excellent color and resolution. My only concern is that the screen display does not come covered with a protective peel-off film to protect from scratches. It really should, but mine came in perfectly fine though...

This meter works well and is easy to read. Handy to tell if your device and charger are really fast charging. It is kinda expensive though. It does seem to pass data between my iPhone and the charger as I can watch the current ramp up over time.

The device is well made with a bright display. But the biggest con is that it doesn’t allow the charging device to pull as many amps as possible and keeps it throttled down to about 0.7-0.8 amps. I compared it with a different USB C tester and the other one showed the same voltage and watts but higher amperes. It allowed my iPad to charge at 1.8 A which would mean faster charging.
