How can I power my portable mini pc.

[dooms]

Hey guys thinking of building a mini pc . Watched some youtube video (Devyn Johnston chennel name) build itx build. So I will want to build something liked that . Currently I have a full tower case take to much space.So I will go aboard to study .And want a pc that will be portable .Dont like laptop much .The only problem is there any way to power the pc when I am outside.Like power staion that doesnt take much spaces and will give my pc power 2-3 hour +

What are the specs that you will build? That will determine how much battery you need.

If you going ITX build with DC-DC PSUs (Like PicoPSU), just hook it to 12V input power, but if you using regular ATX/SFX/FlexATX PSU, well, power station like Jackery 1000W one is the solution, refer to LTT gaming van built for reference/inspiration

You're going to have a problem with energy density. The two lithium batteries in my car can do that, but thats 20kg of battery.

 

dirty calculations lets say all in you're using average 550 watts, 3hrs thats 1650kw/h, so with a 12v battery you'll need a capacity of min 140ah@12v (of capacity, you cant flatten it every use, so you need about 30% higher again). 

 

No offence, but what you want is a laptop, or an itx build that you're going to plug into someones power. I am assuming you don't want to carry around basically a small generator, or power brick like a jackery.

Not going to happen. At least not in any portable form. If you want a small machine that can get a few hours, get a steamdeck.

Thanks for your suggestions.But normaly doesnt Only the browser use 100-150watt

My hugely inefficient old amd FX system has a total power draw of around 70 watts when streaming or doing random office work so yes. Modern hardware you can get down to about 30-60 watts for these types of workloads and if that's all you're doing them you can get away with a much smaller battery system, but the downside is if you need to do anything at a heavier load you're limiting runtime to 20-60 minutes. 

 

If i want to sit down and play a game it's going to be 350-400 watts, with my full overclock in place about 680 watts, might just be me but if i play a game i'm going to sit down for 1-2 hours at a time.

 

 It really just 'depends' on what you want to do.
