Keeping a Fresh Fade During Long EV Road Trips – Any Tips?

Road-tripping in my EV has been amazing, but I’ve noticed my fade tends to lose its sharpness after hours on the road. Between charging stops and scenic detours, I’m not always near a barber. Anyone else deal with this? How do you keep your fade looking crisp when you’re miles from the nearest trim? I’ve tried portable trimmers, but battery life can be hit or miss. Would love to hear what’s worked for others especially if you’ve found a way to balance grooming with keeping the ride eco-friendly!
