What Watts are What?

It's a little bit ambiguous because it also says "Voltage Display Range 0V - 9999V"

Yes well since it's a 3 pin US plug I would think that is what it is designed for?

There is a universal version made:

One would hope (foolish I know) that this is the model that would be shipped.

Or buy the minimum order of 50 from the manufacturer and give one to each of one's friends

It seems that these meters are not as easy to find the right one as it looks at first sight.

Most of the world that uses 220V (or close to it) seems to use 50 hz.  Here we use 220V with 60 hz.  I would imagine that makes a difference.  The universal version you mentioned says: 1.Operating voltage: 230V 50Hz

I did find one from Germany that says 270 V 60 Hz but I will search locally to see if I can find exactly the right item. Still searching . .

Maybe this.

I am looking for the specs on that item.  Every site I look at has this type of plug in Watt Meter but they are always for 220 -240 Volts 50Hz Like Aus, EU, China, or UK or they are 110-120 Volts 60Hz like Canada and US.  Philippines is really screwed up being one of the few countries that uses 220 volts with 60 Hz.  Obviously they build electronics for this market as my aircon has that rating.  But perhaps these plug in watt meters have not yet been standardized for Philippine V/Hz.  I say that because there are a ton of them for sale in Philippines but all are 50Hz and I do not know if that will screw up my aircon.

It appears to have a universal plug in part and it's here in the Philippines so one would think it would work.

Seems like you should get the unit service like Jake suggested. You mentioned it is a older unit. The motor use in the unit is a single phase motor. (two wire) single phase motors have a starting  and a running winding. (coils) Most single phase motors have a capacitor (extra power) connected to the starting winding, most likely the capacitor is shot. (No good) would not be surprise if that is the problem. Capacitor hold a charge just like a battery does and do have a life period. 

When the motor starts both windings are energised, when the motor reach about 90 % of rated speed the starting winding disengage and the running winding takes over. Inside the motor there is a centrifugal switch which operates on centrifugal force and there is a starting winding electrical contact which this switch operates (open and close.). Could be a dirty starting switch also which would render the starting winding useless. If the capacitor is not good the starting winding will eventually burnt out. Could be a number of different things. The starting current is about three times the running current of the motor.

Most likely the problem is with the motor in the unit and not the generator.

Whenever I'm buying a new Aircon,  I always need to convert the HP amount into BTU's first... since determining the strength of any Aircon solely on the HP number  just rolls over my head... but the number of BTU's gives me a clear idea of the power of an Aircon unit.

If you divide BTUs by 3412 it should give you the KW.

Thanks.  I was looking at a few "universals" like that, but when I look close they usually say 50 Hz when operating at 220+ Volts and 60 Hz when operating at 110 -120 volts.  That seems to be the standard.  But I will look more closely at that one.  

But for now I will give it a rest and look in the local hardware stores tomorrow.  Oh that's right, may be closed tomorrow because of some kind of strike.  Well we shall see.
