I ride a scooter around my city for fun and often find people having car struggles. I'm skilled with automotive work, so I figured I'd fill a "go bag" with stuff to bring anytime I'm riding for pleasure and have extra space. My goal is to cover as many common issues as possible while fitting everything inside a 30 liter top box.

My current list is:

• Jumper cables or small jump back (interesting edit at bottom)
• Common wrenches (10, 12, 14, 17mm)
• Common screw drivers
• Maybe common fluids (5w-30 oil, distilled water or coolant, etc.)
• Tire plug kit
• zipties
• duct tape

Suggestions from this thread I will add:

• OBD-II Diag tool
• Telescoping magnet
• cig lighter charged air compressor
• Pliers
• wire stripper/crimper combo tool
• crimp terminals/splices
• multimeter
• fuses
• SNACKS!!!!!!!!
• gloves
• air-freshener/momento type of thing :)

Are there other super useful things I might have left out, or niche stuff small enough that it'd cost nothing to bring on the off chance it helps? Common spec bolts/o-ring sizes, or something like that?

I want to make sure when I stop to help someone I can actually help, and not narrowly miss an opportunity because of an oversight.

Thanks for the help with this :)

Edits:

• formatting list
• adding "?" to title
• added zipties and duct tape to list, added o-ring example
• added suggestions from thread list

Interesting edit at bottom: TL;DR is supercapacitors. Main story: My concern was the longevity and cost associated with jump packs; lithium batteries don't like to be stored at high charge and also don't do great in varying temperatures. Enter the TIL: supercapacitor jump packs, which seems absolutely perfect for my use-case. They're designed to be stored with no charge, and are super happy with offloading all their charge at once. The intended use is to be charged off of the dead battery just enough to breath life into the starter long enough to get it running, but they can usually be charged quickly by other methods like an outlet (plentiful in the city) or a working vehicle.

I'm wondering how I could make a good, privacy respecting public sign up system for an event that protects both the person signing up and myself. I'm hoping for something user friendly, but ultimately my safety is important. I'm not sure what's out there or if I'll need to roll my own, but I'd love some community brainstorming here!

TL;DR: What are some ways I can have a privacy-respecting public sign up for an event I want to host that protects me and the people signing up?

While thinking of ways I can enrich my local community, I figured I should host cookouts/potlucks as a venue to share some useful stuff with the world. I want to cover things like degoogling, basic computer skills, etc. as that's where my skill set is primarily, but I plan to host guest "host's" to cover a wider breadth of knowledge.

If you were one of my neighbors, what would you like to see covered or cover yourself?
