If you’re a photojournalist, you need to have certain small things in your car at all times - and in an organized way. An inexpensive tackle box is best for keeping them available - and organized.
I keep all of the following in a rugged but rustproof plastic tackle box I got at Wal-Mart: nail clippers (shooting photos with a broken nail is tough!); a “clicker” that doubles as a dog whistle for posing pets; a Leatherman multitool; plenty of Band-Aids (you don’t want to bleed all over that dSLR or expensive lens!); cable ties; two Sharpies (one red, one black) for such things as writing my name on gear with or for potentially troublesome events writing a phone number on my arm - and the essential electronic stuff; and earplugs for covering noisy events..
The bottom of the tackle box is where all of the following stay: a roll of fluorescent-color duct tape; chargers for the dSLR and digicam batteries that run on either a wall outlet or 12V cigarette lighter; an adapter for using ordinary AA batteries to power the dSLR; chargers for the smartphone (both wall outlet and 12V).
One other thing I keep in the bottom of the tackle box is an eyeglass retainer - bright pink in case the glasses do get knocked off; it is floating - and I got it inexpensively at Wal-Mart.
Most all of this stuff I got inexpensively - either off eBay or at Wal-Mart - but it’s major brand and dependable. And it’s all in a tackle box the size of a shoe box - and organized.

Do you have a box like this in your car?
