USB-C on the mobile 12,800 is primarily plug and play. Just make sure that the Omnicharge is switched on before connecting the USB-C cable. First, connect the USB-C cable to the Omnicharge, before plugging it into your device. If the device does not start charging within 10 seconds, pull the USB-C cable in and out of your device. If you are still having trouble, try using a different cable.
Note: On PixelBooks and Chromebooks, you will receive a prompt at the bottom right of your screen, asking if you want to charge from this source. The laptop will not start charging until you accept this prompt.
Charging from the USB-C port
Recharging the Omnicharge from the USB-C port is also plug and play. If you plug in a regular USB-C charger, the Omnicharge should detect this as a power source, and accept the power input. In some cases, if you want to recharge the Omnicharge from for example your laptop, the Omnicharge might have trouble negotiating which direction the power should go. In this case, first turn off your Omnicharge, before connecting the cable. If you wish to utilize pass-through charging, wait 15 seconds before turning the Omnicharge back on.
