You might be asking which external batteries work with Solo PRO, and can you use any USB-C output battery with the unit? The USB-C power input to Solo PRO supports the PDO-2 and PDO-3 power profile configurations of USB-C.
Minimum voltage is 12V.
Maximum voltage is 20V.
USB-C power must be above 45W.
The exact unit behavior for power is:
- When you plug the USB-C power adapter/battery. The unit detect the external power supply and start communication with the power supply.
- Always start with PDO-3; if it supported; unit have power and you will see the LED turn red.
- If PDO-3 is not supported on the battery or power supply, move to PDO-2 dynamic mode. This looks for the relevant option that will support power of 45W above 12V. If the controller finds that support on the input device, the unit will have power and the LED will turn red.
- If the input device supports neither PDO-3 or PDO-2; unit will not accept the external USB-C power source and thus will not charge, and there is no LED indication.
Does the Solo PRO Support Fast Charging?
No, the Solo PRO uses a steady power charge similar to laptops, unlike some phone handsets that now support pulse charging or fast charging. While powered off, the Solo PRO takes approximately 2 hours to reach a full charge from completely discharged.
