Is there any way to find out how much power the unit itself is drawing? Every time I plug it in, it trips the breaker in my flat.

it is proportional to the power your drawing. for instance if you have some thing plugged into the load side and it is 120V at 1000W it draws 8.33 amps. but that same 1000W on the line side (230V) is only drawing 4.35 amp. this is not accounting for powerfactor or other losses but gives you a ballpark idea.when you first plug it in make sure it is off and nothing is on the load side. if its tripping a breaker try a different outlet. if it continues something is probably shorted internal to the converter.

I can't answer the question as asked, but this is how i solved the same problem (I have the LF3000 connected to a standard UK power circuit with a 30A breaker. I operate a 1700W 110V toaster with it). Effectively there are two switches involved, one on the LF itself and the other the 110V item being powered. I got the device to work as follows 1. Plug the 110v item into the FS in a switched OFF state 2. Plug the FS into the main and switch on....Actually, I leave mine on all the time. I never switch it off 3. Then switch the 110V device on. With luck all will be well If you you have multiple 110V devices, follow a similar approach The reason this method works is that by turning on the FS without any output loading first, the voltage spikes are reduced Good luck

Can this unit be used to find out the max wattage an appliance uses? I just purchased a portable generator, and would like to see what some of my appliance pull in watts. Thanks

I don't know, the unit stopped operating. No light, no fan, circuit breaker is not popped so I am perplexed.

If the previous answer does not solve the problem, imo you must return it. But also try something else in the outlet you are using to ensure there is voltage.

I'm not sure but I would highly recommend looking for a different brand. I bought two of the exact same model thinking the first was a fluke, but both had the same problem of tripping the circuit breakers every other time I used it despite having used it on an outlet/ 20 amp circuit breaker specifically designated to it alone. Then I read the reviews. lots of people having the same problem. I know it doesn't answer your question, just trying to save you the aggravation I went through.

Honestly I would just give up and run to an airport or train station and buy a new one from another company. As I said in my review, even when mine was in converter mode, if didn't limit the power like it should. It fried one device, but luckily everything else was dual voltage. If your things are dual voltage, my next question would be are you using it worn an extension cord or power strip, because it doesn't like those. Just make SURE your stuff is rated for the higher volts and plug them straight in.

Not sure, mine never does that. If you just bought it I would swap for a new one. Or make sure your connection to the outlet is not loose maybe? Hope you figure it out!

my unit works fine off wall power-- no battery's in unit even---use a meter to see if power is cumming out of the wall adapter.

Probably not. It sounds like it may be defective and needs to be returned (hopefully this is still an option). Before you do so, try plugging it in to another outlet, just to be sure!

It's electric.110, but a pain cause it's own breaker keeps popping, keep looking

I agree with the previous response. If you know the outlet is good and its fully plugged in and you push the on button and nothing happens most likely the power supply in the unit is bad. Time to return it.....

You should be able to reset it right away, if it doesn't reset grounding out(something shorting out) or breaker itself is bad

So I'm not gonna sugar coat....the breaker opened at 4800w surge on test. Meaning 20a @ 240v. Might be the cheap Chinese breaker on the unit, might be a realistic shock load for it to bear.

I have the same problem it concerns me that it may blow the circuit out! Don't know if its normal or not! My solution is to leave it plugged in and to try not to have to plug it in again.

Sounds like the GFI inside is getting tripped? You could replace it with a standard GFI from the box hardware stores to see if you got a faulty one - or check all your electrical connections to make sure they're not getting wet or shorting. I have installed dozens of these and rarely see the GFI trip (usually only after power issues).

I have mine plugged into a gfci outlet in my kitchen. If the outlet does trip you will have to pull the unit off to reset it

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).
