YOJOCK USB C Tester USB Power Meter 2 in 1 Digital Multimeter 3.6-32V 0-8.0A Voltage and Current Tester Meter, Type C USB 3.0 Voltmeter Battery Capacity Volt Ammeter Power Bank Charger Detector

I've had a basic USB power meter for a while, but this one with the addition of USB-C makes it so much more useful with newer devices. The display has many functions and shows a lot of information relating to power consumption. Very handy for testing the charge & discharge capacity of things like mobile phones and power banks

Works nicely

Gives the voltage and current, as expected, but it's awkward to use. I wanted to test my desktop phone wireless charger, but the meter must be plugged into the charger, rather than USB cable coming from charger into meter and then into docking station. The problem is that you can't read the meter in that position. Even when I tried testing on the kitchen counter, it's still very difficult to actually read it because it's basically fixed to the plug socket and you're leaning over the counter trying to angle your head.

I did pay for this myself and it isn’t part of the Amazon Vine Program.I do have one of these under another brand but needed a 2nd one and this looked the best value at the time. These do seem to be generic, with some having a brand name on them and others don’t.As I test a lot of charger and cables, these are really great for seeing what is happening vs. the spec. Where this differs from similar products is that you can go from USB-A to USB-C and visa versa. I have another design that, if you plug one end into a USB-A port, then the other end must also be plugged into a USB-A port as well. Personally, I find that too restricting.You can change the display arrangements but some are tricky to read due to the amount of info it’s displaying, that is unless you’re up close. I tend to focus predominantly on a setting which shows me Volts, Amps and Watts at that time and ongoing.It is easy to use and the display is clear, if a bit small sometimes. You even get a Micro-USB adapter included and a simple plastic storage case. Pricing on this specific design does tend to fluctuate quite a lot depending on the brand, I paid £16.74 for this one, but have seen these (not this specific one) for £25 upwards. For the price, I thinks it is decent value and highly portable.I did run a comparison test compared to the other one I had, they are exactly the same device, and the readings were the same on both.I hope you found this review & photos interesting, informative, and useful. Thanks for reading.

Great item working fine

Good device easy to use does usb c micro usb etc

Great little tool for work to quickly check if a USB port is functioning ideal for the motor trade.

Bought it to help with multiple mini projects around the home involving diy power packs, cheap solar panels, and metering various other usb devices. Works well. Seems reasonably accurate. Knocked off 1 star because I have some difficulty metering my laptop power (perhaps the USB-C PD on it too powerful for the unit it doesnt recognise it) and I had to buy some USB adaptors separately to make it easier to use (female to female etc are useful). Those may or may not be a concern for you. But good product otherwise.
