use this formula V(volts) x A(amps) = W (watts)

so on the stickers of your gear look for the power info

as your american your volts will be 110v
then add up all the amps that your gear requires we shall say 10A amps for this example
then you multiply those together and that gives you the wattage requires and you want to give a bit of head room too so

110 x 10 = 1100 watts, so you'd want to give a bit more so you'd need a minimum generator of putting out 1500W @ 10A, just do that again with your values and you're set

the output is different from the consumption. the tag to look for is on the back of the gear it will tell you input volt range and watts or amps as consumed by the equipment. a powered speaker rating of “2000 watts” is what the speaker consumes from the amp driving it not what the amp consumes from the plug. your “2000 watt” powered speakers will consume no more than 8 amps. your laptop will consume .75 amp when the battery is dead and the controller is .5 amp. add your amperage 8+.75+.5 = 9.25 amp. 9.25 *120volt= 1080 watts. rule of thumb is operate at or below 80% of the generator rating. never use a generator rated at your consumption. a spike will trip the generator. if 1080 watt is your number use a generator rated at 1350 watt or above. as a reminder there is no tag on equipment that will give you a wattage rating at an amperage. 1500 watts is not equal to 10 amps

one correction i forgot to say both speakers will consume no more than 4 amp a piece 8 amp combined

Generator are not the best option for sensitive audio equipment, and generally bigger is better.

But first figuring out how much power you are using. Reading the stickers on the back of everything and adding them together is usually not true. I know the math gets hard so just skip the ohms law stuff and buy a Kill-o-Watt gauge. All home improvements stores sell them. Plug all your equipment you going to use and crank it up. Now the gauge will give you your true power consumption. I suggest this even if you are not using generators.

I suggest you to get a generator that is twice the wattage rating of what you get on that gauge. And all generator are not made the same, typically the more expensive one are better. Generator are know for under-voltage and bad quality of power output, so look for pure sine generators and consider using uniterupted power supplies unit.

Hi,

I got a generator specs :
220v
1.6 kva output rating
2 kva max output
Phase 1

DC 12v, 8A

I dont know how to find the wattage it gives. In DC it is 12 * 8 = 96W but how abbiut the kva.

I want to connect ir to 600W speaker, 800W mixer and other led lights as i learned all these work on AC except Led

Hello, how much power does your equipment need? Then can recommend suitable generator to you. From your description, small one will be enough to satisfy your needs. You can get one from this website: www.dieselgeneratortech.com
