Re: most battery efficent way to tether?
I agree with Schettj; this even works when you don't have a 1A supply coming in from the laptop. Using NuePower, I noticed that it was discharging at around 450mA while the computer was giving me about 480mA. It was charging, but not at a rate that would be useful (unless you want to wait 45 hours for it to charge a depleted 1340mAh battery).
Has anyone tried using the dual USB adapter to charge from an AC outlet while tethering?
