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.)
