This is typical of any electronics with a well filtered power supply. Some of the older devices that used a lot more total power, including tube filaments, would use a series thermistor (with negative temperature coefficient of resistance) to limit the initial surge to a reasonable value. It also increased the life of the tube filaments, like soft starting an incandescent light bulb.
Modern devices with far lower total power consumption apparently do not feel the need to mitigate the surge.

When my psw inverter and the kill-a-watt are delivered I will send a complete list of watt usage, I've noticed changes in my cable box (which stopped working), and my stereo records speed was slowing down, so I stopped using the system until my new equipment arrives.

Yep - that happens with msw inverters. Battery chargers if they don't fail outright may *seem* to work, but their algorithm timing is totally thrown off, and you end up killing the little tool battery you are attempting to charge.

That being said, about the only thing I'm running from an MSW inverter without any seeming problems is modern LED bulb lighting (like GE, Sylvania, etc...)

I finally got figures.
AMPS. WATTS
T.V. .58. 67
CABLE BOX. .67. 42
CD. .04. 2.5
ALL UNITS ON. 1.38. 150
Then I lowered the lighting on the T.V. AS SUGGESTED.
FINAL READINGS. 1.19. 142

I WILL GET THE FIRE PLACE FIGURES WHEN IT GETS COOLER, I THANK YOU GUYS FOR ALL THE HELP...

My fireplace start-up is .01amps and 8watts
Blower.--high--.65 amps.--45watts
Blower--med--.49 amps--30.3watts
Blower--low---.44 amps--25.6watts
The fire place will run alone.

I am a little confused how you are calculating the wattage for that blower.

W = Amps x Voltage. or W / Amp = Volt

45w / .65amp = 69v
30.3w / .49amp = 62v
25.6w / .44amp = 58v

So what is the voltage rating of that blower?

All amps and watt figures were taken with a kill-a-watt meter.

Ok. What is the voltage reading when you got the amp and watt measurement?

Also are the "Watts" really watt hours over a period of time. Otherwise the W = V x A calculation doesn't work.
