I bought this inverter at you-know-where. I will be calling the tech

support number given in the manual, but I thought I'd run my questions by

you folks also.

1 -When I power it on, the fan starts, runs for about a second and then

stops. Is this normal? Will the fan start again if required?



2 - When I plug in a lamp with a 72W bulb, it works fine. When I plug in a

air mattress pump (120V, 1.0A) the pump may or may not start and the

inverter chirps its alarm. Sometimes the pump seems to run fine, other

times, not so much. The chirping is more evident and consistent when the

pump is running at what appears to be full speed.



Shouldn't even a cheap 1000W inverter be able to handle the pump without

breaking a sweat?



(I'd return it and try another inverter, but both of my local stores are

out of stock right now.)

It sounds defective to me. It's rated 1000W continous, 2000 peak.
That should certainly be able to handle a small 1A motor. In the
reviews a guy said he used it to power his impact wrench to change a
tire......
