Powering Mini PC

Looking for suggestions on powering on mini PC on a battery. Trying to keep it light weight. Would a 12V lead acid battery with a buck converter work? PC is 12V 1.5a draw

If the pc requires 12v and the battery is 12v, why do you need a buck converter? Also, the battery amps will matter. Because if the PC is 1.2 amp draw, a 2 amp battery will only last little over an hour.

Ideally the battery should be 8 or more amps. You can find many mini PC's that use +5 and draw an amp or less on gearbest.com
