If your having trouble identifying a detected device or just curious about something, here’s a tip.
On electric devices there is a tag, sticker or stamp that states either the wattage or the amperage of said device. I’ve taken a couple pictures for reference; the first shown from a Rowenta clothing iron and it shows it’s wattage of 1800.
The second is a power adapter for a router and instead of wattage, it shows amps. This is how most are displayed.
Take your amps which for this device is .8
And multiply by the known current which is 120 volts
.8x120=96 watts ( a lot more than I expected for this device)
The reverse is true and you can take that 1800 watt iron and divide the watts by volts for amperage.
This may help with identifying a mystery device or adding devices together that are on the same circuit.
If my house was wired with 15 amp breakers like most are and I plugged the iron in while anything else was plugged in somewhere on that circuit, I’d trip a breaker.
This has helped me with the showing half the wattage problem. I’ve been able to go read the label and I’ve use the kill-a-watt to verify.
