Sometime ago, I bought an Onion Omega2 Pro and flashed it with OpenWrt 18.06. I plan to take my Omega on the road, so I installed a Li-Po battery on the device, so that it does not need to depend on USB power input. One big question is: what's the remaining power level?
power-dock2 to View Battery Voltage
The standalone Power Dock has a set of battery indicator LEDs that visually tells how much juice is left.
