I need to use this on the job site. how strong of an inverter would i need. How many watts? and 15+ AMPS?

Ohms law says amps X Volts = Watts, So with the information provided the compressor runs on 120 volts at 15 amps will be 1800 watts. However when this compressor motor starts under a load I'll bet it spikes upwards of 20 amps probably around 30 amps so if your going to use a power inverter to run this compressor better be a good one ! At least 3600 watts at the minimum

I've used mine on job sites but you need a dedicated 29 Amp circuit for it.If your converting power and need an inverter I'd try to find a compressor that dies not draw so many amps cayse it will take quite a bit of start up amps from your power source

need 20 amps . Not sure on inverter . And you need a heavy.duty extension if you use one.

I promise you, this inverter cannot handle 200 Amps. It's output rating is around 4 Amps (400w/110v=3.6A) at 75% efficiency, the input current would be around 45 Amps (400w/12v=33.3A /0.75=45A).

ihave no idea how many watts are required to run your machine, but here's the math so you can determine this. Multiply the battery's "Amp Hour" rating by it's voltage (12 volts let's say). This will give you the "Watt Hours" available to run the machine, presuming a fully charged battery. I presume also that the machine draws less than 500 watts....the rating of the inverter. Amazon sells a nice 12 volt 35 Amp Hour battery for about $65.00. SO: 35 AH X 12volts = 420 Watt Hours available (call it 200 watt hours because you never want to deplete the battery by more than 50%). As an example, let's say the machine draws 25 watts (check the labels or paperwork). So you have 200 watt hours available, divided by 25 watts = 8...the number of hours you should be able to run the machine with this inverter and that battery. Just find out the actual watt consumption of the machine and do the same math. By the way...for safety...I would leave the battery outsise the tent, with the inverter inside. I hope all of this was helpful.

Should handle it easily. This inverter was good on power, but mine failed after a few months with no load attached at the time.

In the description it says 900 watts. It says on the back of my unit '660 watts'. You could use a 1000 watt continuous power inverter or higher for this product.

Ideally would be 24 watts, without considering conversion losses etc. Being a switching supply, it should be close to the that (basic formula is P=I*E, P is power, I is current, E is volts).

Regardless of the intention... You calculate Watts by multiplying Volts times Amps. In your case you are looking for an inverter that can handle a minimum of 588 watts; furthermore you must consider the initial spike in power draw when the oxygen concentration device is first activated. The answer is NO, THIS INVERTER IS NOT SUFFICIENT FOR YOUR APPLICATION.

That's what this is used for...outdoor lighting. And, I am not an electrician, but I think a 15 amp unit will support around 1500 watts of lighting needs.

The 175 watt inverter will max-out at 1.46 amps @ 120 volts. I don't understand the part of your question about "Do amps apply only to USB?" -Roger

I would not recommend this kit for a 5k watt inverter. Run on over to Home Depot or Lowes and buy the same terminal hook ups but buy the 1/0 gauge wire in bulk. Better copper wire quality. The kit has thin copper strands (100) and the big stores have the thicker copper strands (16) better for flow.

I purchased this same inverter with hope to use 4 Renogy 240 watt PV panels. It could work but you need to add up the total Amps output for each panel which was 7.7 x 4 =30.8 amps. you will need to have a circuit breaker that will handle this amount of Amps or your circuit will trip. I decided to use different technology. Good Luck with your project.

This does not have enough power for that usage. Plus mine died after limited use, right after the warranty expired. You will need an inverter of at least 1500 watts- continuous. You would also need a car battery to operate this and a battery charger to recharge it. I would think you would be far better off using a long extension cord rated to handle 1800 watts.

As long as you have a large enough battery bank feeding it there should be no problem. I have a series-parallel battery bank with 12 batteries with a 1,400 amp capacity & my inverter never misses a beat.

i would not recommend using this with an inverter, you would be creating a fire hazard.

115-230 VAC is a selection, not a range. So if you select 115 VAC then you have selected the correct output for this inverter as it is a nominal 120 VAC inverter. With a range between 7.5 amps and 15 amps being drawn by the compressor, the inverter is just a bit shy of what you require. Another big problem will be the stoutness of the battery you are using. From a static 12 VDC source (stand alone battery), converting it to 120 VAC, drawing 15 amps, the power used would be 1,800 watts. That is a little past the rated 1,500 watts, but not beyond the momentary peak of 3,000 watts. From an active 14.5 VDC source (a 12 Volt battery driven by a alternator), converting it to 120 VAC and drawing 15 amps, the power used would be 1,740 watts. Again, that is a little past the rated 1,500 watts, but not beyond the momentary peak of 3,000 watts. But here is the catch, an AC inverter is never 100% efficient, so the calculations stated above are actually worse. Could be 20% off or more 'off' due to inefficiency. Technically, you could run your compressor for a few moments without damage to the inverter, but this inverter would not be the proper selection for your work load. I would select something in the 2,400 watt range for the continuous power required that you seek. This would give you 20 amps minus 20% inefficiency giving you 16 amps of reliable current. So 2,500 watts, with the ability to surge to 5,000 watts momentarily (allowing a 100% overage of current drawn on start up for the motor of the compressor) should fit your bill. All units will be very happy with each other (provided you have a robust battery, or battery bank). An "8D" battery would serve you well (but pretty heavy at 161 lbs each). Do not forget "voltage drop" that happens, and make sure you use HEAVY cables to the battery; perhaps 2/0 pure copper (not copper clad) cables. This will keep your input high. It is worth the expense (and you only buy them once).

The pump unit needs about 550 watts....so whether 12 vdc or 24 vdc., your inverter must be able to deliver 550 watts.

I am not familiar with the inverter you are talking about, but I used this unit in a RV with inverter and generator with no problems. It pulls 1800 watts
