Perfect tool to see how usb devices perform
I received 2 of these for Christmas 5 months ago. I am in no way associated with the company, I just found a good product and would like others to know. Features: you can turn off the screen, change between °C and °F, it records how much power was used, you can access multiple records of power usage, data transfer is unaffected. It reads between 3.6V to 5.4V (so far), however the screen turns black when usb-c fast charge exceeds ~6V, though it is very temporary and limits 9V to 5v usb-c. In general, the amps (blue) read between .001 to 2.8, yet to see 3+. The higher the amps are, the faster the charger. I use it to determine how much power many different chargers use, both in amperage and watt-hours of capacity. I also use it to find the best angle to place my usb solar panel, which is often straight up on a cloudy day. It is seated well in the housing, not wiggling or sliding around like my green thumb drive(hence the glue). It also comes with a usb plastic cap for the male end, and a folding plastic case, though it’s durable and I carry it without the case to save space. This is accurate, i tested it with a 22Ω+ 10Ω resistor in series to make a higher wattage 32Ω resistor, along with an ohms law calculator to compare. The meter read 32.2-32.4 ohms, which is very respectable (usb cable has a little resistance) and the other math checks out as well. I read how some have inaccurate meters, but I guess it’s been fixed since then. Overall, if you want to check how fast something charges, what voltage your charger is at(safety shut-off), how much power is consumed, and even the resistance of your charger+battery, then this is the meter for you. (Yes, that does seem kinda staged like an ad, but it is a good product)

Muy bueno
Me gustó para verificar el consumo de mis dispositivos USB. También lo he usado para verificar la carga de las pilas de mi drone.
