A UV flashlight will charge up glow in the dark in record time. I actually carry a small rechargeable UV light in my work kit so I can charge up the glow in the dark markers I used to identify equipment or as administrative lights. I use them a lot on zipper pulls.
I usually don't need it, sunlight exposure is usually pretty effective, but it can still be handy if a marker was in a pouch all day. The UV flashlight is also incredibly small, keychain sized, and topping up a glow marker uses a minimal amount of power. It's much less disruptive and more power efficient then to using one of my high candela or high lumen lights for the same purpose.
