Hi, I was surpised to see the PC handhelds with an untethered TDP of 25 Watts (~30 Watts for the whole device) going different routes to get the needed power.

  • the ROG Ally has a higher voltage but lower current (30 Watts / 15.48 volts would need a current of 1.94 Amps)
  • the Legion Go has a lower voltage but higher current (30 Watts / 7.76 volts would need a current of 3.86 Amps)
  • the MSI Claw has a medium voltage and medium current (30 Watts / 11.61 volts would need a current of 2.58 Amps)

Are there advantages or disadvantages to the different solutions (for a mobile device) or doesn't it matter, if the needed/delivered power is the same?
