Mobile is the preferred mode these days and the Mini Lumio+ takes this on. Resembling a hard-cover notebook (it reminds us of a Moleskin), it's actually a compact portable LED light plus a battery pack for mobile phones, all in one. Rechargeable lithium polymer battery for up to 10 hours of continuous light and 4 times more battery power for devices (via an embedded micro-USB charger.) Lumio opens up 360 degrees and gives off a light that's slightly brighter than a 20-watt bulb. Super-strong magnets in the "book" cover handily adhere to metal surfaces. In town or on a campground, do it by the book!
