The battery sounds small, since it's only 2 or 3x that of my phone. Other than that, what incredible specs for only $200!

- baybal2 7y ago10Ah * 3.7V = 37Wh
- krastanov 7y agoI am pretty sure you mean "Ah" (i.e. current * time, i.e. charge, not "A/h", which is rate of change of current or second derivative of charge). Similarly it is "Wh" (i.e. energy, i.e. "power * time", not "W/h" which is the second derivative of energy).
- baybal2 7y agoThanks
- sigstoat 7y agoignoring the issue of units, that's overly optimistic for batteries. the voltage drops as charge is depleted.
- krastanov 7y agoIndeed it varies between 4.2V and 3.1V, but the value op chose (3.7V) is not an unreasonable average number. But 3.5V probably is a better guesstimate.

- solarkraft 7y agoThis is not unusual for a laptop, although on the lower side. What's the power draw?
- noobermin 7y agoIt's a SBC so its power draw isn't that high. The question of course is mainly what the power requirements of the screen is.
