Would a smaller inverter last longer?

Interesting question...

my gut says "probably not worth it"

Yes a larger inverter "can" use more power simply because it can handle more watts but I don't know if you are only running 100 watts through it if there would be more overhead on the total consumption or not ...

Anyone here with a degree in EE might have some insight. Or just get one and play until the batteries are dead... and then compare... LOL

 

You big inverter will only pull from the batteries the power it consumes. If your uses pull 120 watts, that's all it pulls from the batteries, no matter how much more it could pull. Think of it as dipping your coffee cup into a small pan of water or dipping it into a swimming pool. Either way, you are only pulling a coffee cup amount of water out of the "water supply" or battery.

 

You want an inverter that can handle double what your normal use is. Mainly for those times where you might peak out on your draw. So if all your normal usage is 150 watts, you want at a minimum of 300. And from what I recall a ps4 uses a lot more than 45 watts.

 

@TROOPER to TRUCKER would probably know...

 

Actually I had a APU so can't help much here

 

I meant regarding the PS4 power usage.

 

I run a Xbox one lol

 

It is really a pc so should be about the same

 

Well, I tried. I used to know the answer, but it's been years since I did any solar power calculations..
