hi I'm new to this hope it's in the correct spot.
I'm after some advice I'm thinking about a PS4 game console mod that I'd like to do that involves powering from a battery pack, however I want to figure out how to determine the battery size to power console I was thinking of maybe replacing the internal power supply with rechargeable batteries any idea of size I would need and mAh?

Just get a car battery (12V) and an efficient 12v DC to 120V A/C inverter (30 to $60). It won't last 2-3 hours if you use it full time but you'll be close.

137 watts = 11.5 A at 12 v (round up to 12 or 13 because of inefficiencies in the inverter).

13A for 3 hours is 39000 mAh
12A for 2 hours is 24000 mAh

So, 24000 to 39000 mAh will be a good target.

Good luck.

What if I removed the power supply altogether would it be possible to power the PS4 from a battery ?

Yes, it is possible. It makes your project more difficult because the power supply is supplying 3.3v, 5v and 12v to various parts of the PS4. The power supply is likely 80% or 85% efficient at converting AC power to the voltages needed. The BEST you can hope is 112Watts to power the unit basic unit.

Unfortunately, if you use lithium batteries, the 3.7 v cells, you'll have some losses converting that to 3.3V, using lithium batteries to power the 5V will also have losses because two lithium cells in series gives 7.4 volts, and similar problems for 12v. Typically, you'll need voltage regulation within 5% of target (no matter the state of charge or discharge of batteries.

In other words, a good sized lead acid battery will still be needed to supply 110 to 140 watts for 2-3 hours.
