Since you can input only one line voltage, will you get erroneous power consumption displayed since most houses have items that run off of 110V and others off of 220V? Power(watts) = current times voltage.

The unit attaches to both legs of the incoming power so it reads 110 and 220 draws.

Voltage is not measured in Watts.....5 volts. It draws 0.4 amp or 400 mili Amp most likely. (it also makes sense). But why are you concern about power input??

Yes. wattage has nothing to do with a standard 120v system. Its all about the amps.
1379809
Double check the amp rating on the appliance and multiply that times the voltage to get the actual watts. Just be careful with appliances that have a high starting current...... like anything with motors. They may over load the transformer and trip the breaker(s).

Watts = Power = Voltage x Current (per standard electrical engineering texts) and is independent of time or cost units.The power rating (watts) is usually given in the back label of appliances. This is a description of the engineering consumer rated capability of the system. For appliances, in general, it assumes either 110 or 240 V as appropriate.The energy cost rate (cents/kw-hr) can be found in the electricity bill. This is useful for estimating energy cost and also for making sense of your electricity bill. It varies as a function of the cost the utility company charges for a given amount of electricity.

Probably not since Power (watts) = Voltage (volts) * Current (amps); 120 V * 4.5 A = 540 W

In the USA 110v is 110-120v residential voltage. We only use 220 for appliances.

It can be either be the 110 or 220 volt. If you are living in the US. Voltage in your home will be fine if have 220 volt it just more house power for the breaker in your home that all.

Yes, with a converter. Amazon has two converters in the $13 TO $14 range. You need to convert from 220 VOLTS to 110 VOLTS (not watts). Search for "110V to" let it fill out the rest.

That depends. Appliances with motors can take extra current (or watts) at startup that might be 2 or 3 times the running current. The Kill-a-watts does not really detect that peak turn-on wattage. But you can watch the display and it will update in a second or two and you can roughly how much current (wattage) the appliance takes. But you will need to watch it at startup. For appliances without motors, you can just look at the typical wattage and get a pretty good feel for how much electricity it will require.

Should have no trouble with 110. that's what I used it for; tracing standard 110/120 power outlets around the house. I labeled the outlets to my circuit breaker box, so now I know which outlet goes to what breaker switch. Hope this helps

I think the question was... will this unit use 44 watts of power no matter the load? ie... will this unit still consume 44 wats if you only have a 5 watt load...My best guess is it will only use what it delivers to the load plus some wasted power in the 120 to 12 volt conversion process as there are no 100% efficient methods of conversion.

You have to calculate the total needed power for your appliances. This converter has 100 Watt capacity. Add the watts (power consumption) of each device you going to connect at the same time. They should not exceed the 100 watt.Volt x Ampere = Watt

Equipment uses standard 110 house current. Using 220 volts would fry the delicate electronics.

Because of the difference in wiring, using this switch for a 220 volt circuit would be very dangerous. A 120 volt circuit consists of one line with power and one without power. A 120 volt switch breaks the line with power leaving the circuit dead. A 220 volt circuit has power in both lines. Breaking the power in one line would leave power in the other line. A 220 volt line switch must be used as a 220 volt switch will break the power in both lines.

Voltage is 110, don't buy this product, it is not a high quality product. Dont' waste your oney on it. I only used it once and never used it again.

A regular outlet in my kitchen works fine, so 110 works. I use a circuit where I am not running other things (dedicated), just to make sure I will not trip a breaker.
