Maybe it's the only thing that stuck with me from my brief stint as a boy scout, but I have the need to have the right tools with me at all times. I almost always have my backpack with me and I make sure it contains the stuff I need on a regular basis or may urgently need from time to time.
This assortment works for me, and may provide some inspiration for others.
My compact kit contains these essentials:
- Eagle Creek Travel Gear Pack-It Quarter Cube - to hold all the stuff. It has a zipper for 3/4 of the circumference, opens flat and has a handle. What more could you ask for?
- Samsung OEM 2.0 Amp Travel Charger - You should always have a spare on you and you should ALWAYS make sure it's 2A so it can quick-charge a phone or charge a tablet
- Cisco-Linksys UTP510 Network Cable, Cat 5, 10 Feet - this has come in equally handy in client boardrooms and hotel rooms
- RJ45 8-pin Modular Inline Coupler Straight Through - if I'm in a hotel room that already has a short network cable, I can use this to add my own and get much longer reach
- Targus Laser Presentation Remote (AMP13US)
- Nexxtech 43-in-1 USB Card reader - sadly discontinued by very versatile
- Spudz lens cleaning cloth in a handy pouch (18% Gray) - this is handy for cleaning phone and computer screens and fragile lenses
- About ten feed of duct tape, rolled - if any of the other tools don't fix it, this might!
- Roll of electrical tape (red) - doesn't take up much space, can be used for small repairs and because it's red it can be used to mark things
- A bunch o' mini Sharpies on a split-ring keychain
- Measuring tape
- An 8Gb USB thumb drive containing only (a) the full PortableApps suite and (b) a Windows7 recovery image
- A 4Gb USB thumb drive containing only a recovery image for my Chromebook
- An EMPTY 4Gb USB thumb drive - if you want to know why it's EMPTY, read here
- An assortment of plastic collar stays - to keep unruly collars under control
- Spare cufflinks
- Replacement earbuds for my Motorola S10-HD Bluetooth Stereo Headphones
I also have a travel kit (which is red, to easily distinguish at the bottom of my bag) that isn't always with me but has the essentials to keep presentable on the road. A separate Altoids tin contains band-aids, ibuprofen, vitamins and earplugs.
