What can i run with a 500 watt stanley converter


Assuming the output is 120VAC, you can only run items pulling about 4 amps. If the voltage output is 220 VAC, you can only run items pulling about 2.25 amps. Read the labels on the devices you want to use, they should list either watts or amps used.

To convert amps to watts: Current times voltage
To convert watts to amps: Watts divided by voltage

How can I connect PS3 to ACER X110P Projector


does the projector have an HDMI port?
i would buy the cable that is HDMI from the PS3 (unless it has HDMI already)
HDMI converter (HDMI to DVI or VGA) typically don't work well because you are changing the signal from digital to analog through a cable. you want to use a cable that is the same on both ends.

I have recently replaced the wiring in my utility trailer and mechanic has tested lights when in the shop and says they're all working fine. Hooked it up to my pathfinder and lights were not working. ...


lights on the trailer are supposed to only work when the vehicle has its lights turned on. brake light problems is easy to figure out. it should run off a yellow wire for driver and a green for passenger. see if you have power with brake on. if so check the bulb. if not then check your 4 way flashers which run off the same general circuit. if 4 ways work but no brake lights double check your converter connections.

I recently purchased a schumacher 410w inverter, while it came on right away and powered my electrical device the cooling fan never came on. Is the fan supposed to run all the time, once its connected.


I recently purchased a Schumaker 410/820 watt inverter. I immediately hooked it up to a brand new deep cell batery I had purchased just prior to receiving this inverter.
I plugged in several devices to make sure the inverter worked and to get some idea of what devices I can expect this unit to handle.
I noticed that the fan only ran when I plugged in a device that drew a certain amount of power from the unit. I also plugged in a CPAP unit to make sure the inverter would operate the unit properly, and noticed that the CPAP only drew 38 to 40 watts of power and the cooling fan on the converter never came on. When I plugged in an oscillating fan it drew around 128 watts from the converter and the cooling fan immediately came on when I turned the fan on. Based on that, I would assume that the cooling fan in the converter only runs when there is enough power being drawn through the inverter to cause the inverter to heat up enough to cause possible damage to or failure of the inverter. I haven't taken the time to find out the power draw at which the cooling fan will run. Hope this helps.

Bought a new vector maxxsst 1200 watt inverter


Inverter run on batteries sir, and if these batteries are not charged, the run time {the number of hours it will work} reduces.
S0, you will need to connect the inverter to a power source.Theses will allow your batteries to be charged and enable it to run for a long period of time.
Make sure your batteries are still OK.i.e working properly

I have a 39 ford 6 volt battery operated car. I


you need a voltage doubler circuit which feeds from your 6V DC system and converts it to AC and steps it up and converts it to 12V DC. This device might be difficult to find. OR use a 6Vdc power inverter and just use a 120volt AC fan if much easier to source out in your area.
You might want to try a 12VDC high speed fan and see if the 50% reduced speed is already sufficient for you.

It is called an inverter, and it may not be hooked up, u will have to trace the source power for the outlets and at the source add an inverter to change 12 volts DC to 110 volts AC.
