I usually carry a Micro-Start Antigravity Batteries XP-3 in my jacket pocket & iPhone with it’s own mophie charger case. Micro-Start can also charge any time phone with usb plug. I have yet to carry this but if I think about it and the bike has a bag with room, I guess I would add the plug and go tire plug kit and air compressor. But, I would call a tow truck or a friend to get my trailer for anything that needs tools because all the tools I need stay at the house.
