Every boondocker is different in terms of what they use their power for. Some have laptops or other e-devices that they "just gotta have." Others can't do without a bit of television. Some find it important to fire up the furnace (and associated electric fan) to take the chill off. But there is a common denominator – most everybody needs to run the lights at night.
They aren't big – standing only about 7" in height, with a "lamp" area about 3" in diameter. But as a 'task light' you can sit the device down where you need it, then point the light where the light is required. Great for reading, cooking, caring for 'personal needs' by night. And at about $16 each, they're pretty easy on the pocketbook.
Now, we've had "experience" with some budget solar lights, those you see folks lining the garden path or the border of the sidewalk with. Those $1 cheapies are just that – they last a couple months, maybe a couple of weeks, and they're done for. We were concerned that this might be the same here, but customer reviews of this particular light are favorable, and the design itself was originally put together to help folks in impoverished lands have lighting that didn't require batteries or liquid fuels to run, so some thoughtfulness was put into this product.
According to users, running time on these lights works out like this: Brilliant light for the first three or four hours of operation. Dimming down from then on, but still usable after seven hours of operation, after a full charge by day. A "glow in the dark" power switch makes it easy to flip the light on or off, and of course, without continuous use, the battery storage on these should make your light last longer.
Pick up a couple, or a few, try them out. See how you like boondocking, then consider making the jump to solar panels up roof-top. This may be a way to help make the transition.
