I have been playing with this mod for a while, and found it rather irritating to have to carry some form of massive power storage along with a charger wherever I go to charge up (like for instance, a TE power cell, or cyclic gps marker to mark the location of each of my preferred charging ports. I hereby humbly request for Thermal Series capacitors to be able to charge any power storage cyberware if set to 'Charge Equipment' mode. Honestly, solar skin combined with the metabolic gen and cardiovascular coupler doesn't really cut it if someone wants all four cyberlimbs with appropriate upgrades, especially if they want to combine it with cybereyes.

The balance of the mod relies, among other things, on the power usage and generators. Using a portable external charger defeats this balance, hence there's no reason to add such support 'as is'.
Generators aren't intended to cover a severely upgraded player. That player needs to choose/design their path : using more batteries and recharging periodically, switch off what they don't need to save power, consuming Neuropozyne, etc.

This usually isn't a huge issue. The ultradense capacitor upgrade provides a decent amount of power storage and if you need to charge on the go, consider installing REwired and using the consumables. They can recharge you.
