A similar question was recently asked in one of the Facebook groups is browse.

From what I can determine, the PRX818XLFW is rated to draw 300-watts of power, as is the PRX815.

JBL doesn't appear to publish thermal or power specs under various loads, so let's just assume that each speaker draws 300-watts at around the clipping level.

4 speaker cabinets @ 300-watts draw each = 1200-watts

Your Pioneer DJ DDJ-SX3 appears to be powered by a 5-volt AC adapter... so, conservatively, let's say it draws 100 watts. Same with your laptop adapter.

Your entire set-up appears to draw around 1400-watts of power. As others have said, the number can vary based on the type of music - EDM will draw power for longer periods of time (instead of "bursts" found in typical rock music).

I would think that a Honda EU2200i generator would work well for this application. The Honda EU series are well-known for their reliability and quality. It's slightly larger than a lunch box and is very quiet. "Buy once, cry once."

I went back and forth trying to get the best inverter generator I could for the money and all roads led to Honda or Yamaha. 
I looked at all those you have mentioned and some of them have very good reviews. Thing is if you use a generator for tail gating or for back up to run power in a travel trailer or something then no biggie if it stops running... If running sound with a paying audience relying on you to keep the music going and the genny craps out - different story.
I chose Yamaha over the Honda because I got a great price - no other reason - I have a Yamaha  EF3000 and 2 Yamaha EF2000's. This way I stay modular. It also means I can move them around myself quite easily- the EF3000 has wheels and the other 2 are only around 50lbs each.
I have used all of them at one time or another when my power has gone out at the house ( recently during hurricane season) and plenty of times with my PA.
I can run full stage - SRX828p, 2 x SRX818p, 2x SRX815p plus monitors and all backline including LED Pars off them by splitting half the stage from the EF3000 and the other half off the 2 smaller ones wired in parallel. Works like a charm and never misses a beat....

With your rig I suggest you get at least either an EF3000 or the equivalent Honda EU3000. You will need some headroom as you never mentioned lights which I presume you will be using.

Thank you i appreciate your shared knowledge. As i have researched all night, Honda and Yamaha look like its the way to go.

Thank you lights and stuff will definitely come into play as well and these inverters can be hooked up in parallel which is also great.

Hello my name is Steven and im new to the mobile DJ world. I have purchased 2 JBL PRX 818XFL,s (1500 w each), 2 PRX 815w,s (1500 each). Im using a Pioneer DDJ-SX3 and a laptop. Im going to start DJing at events and outdoor events.
I was wondering if anyone can give me some tips and what exactly is the best way to power these bad boys. Iv been looking into 6000 watt inverters so far but have read that they can have issues with high power low frequency subwoofers. Any tips and recommendations would be greatly appreciated.
Thanks!

I do one of the larger tailgates near Mercedes Benz stadium in ATL. My typical setup is:
2 - Crown Itech 8000
2 - JBL SRX718
2 - JBL SRX715
2 - generic 50" TV (~100 watts each)
2 - CDJ 1000MK3
1 - Allen Heath 9:2
1 - Laptop
2 - Shure ULXP
4 - SlimPar 56 (lights up the tent nice for night games)
1 - analog mixer sometimes (A&H mixwiz16 or smaller)
I RMS limit the 718 channels only. There are times during the peak of the party where I have to watch myself to keep from overloading the generator. At times when I'm only playing the TVs I can move the generator into Economode no problem.

I use the Honda EU3000i. This is the right choice for me not only because of the power I need but also the size of the gas tank enables me to go all day without having to shut down to refuel.

I play old school R&B and Hip Hop and sometimes do track acts.

Also, I prefer passive systems outside at tailgates because I dont have AC cable all over the place and dust clogging up amps and powered speakers. I try to keep my amps inside the van playing outside.

Tracy hits on a good point I forgot that is worth mentioning again. You have to pay attention to the gas tank size. The Honda and Yamaha will go for many more hours than some of the cheaper versions like the ones you mentioned. This makes a HUGE difference if you don't want to have to power everything down to refuel or invest in extended fueling systems.
My run time starts a good hour or more before the show because it has to include system test, sound check and sometimes background music so there is at least an extra hour on top of show times PLUS if I need to keep lights on at the end of the show if outside ( to be able to see) and maybe music to play out the night. I'd be really limited if I could only run my generator for 4 hours or less.
