The Fantastic Fan, model Endless Breeze is the box fan that sits on a table. 12-volts of course and one of the most energy efficient fans ever made. Use a 4-amp (minimum) 12 volt power brick for plugging into an outlet. Over the course of a total power failure of 12 hours, the Endless Breeze on 3 (high) will consume a tad more than 30 ampere hours. A group 31 AGM battery will laugh this off.

Search for the 18 watt rectangular 6 chip lamp. Look for flood beam. It really uses ELEVEN WATTS which is less then one amp. And this little lamp puts out perhaps the most efficient lighting I have ever seen. With a power outage I dolly the battery to the kitchen, make a fruit salad, then to the bathroom for evening duties including that splendid shower, then off to the bedroom for a reading light. The intense light beam I point to the ceiling and even with my horrible weak eyes, I read just fine. I have a Kindle and a Nook both with back lighting. When it comes time to sleep I play the fan over the bed, strap on the Bi-Pap and it's Good Night Irene. What inconveniences...?
A genuine vacuum Thermos bottle rather than foam insulated will keep an ice rich cold drink really cold on the night table. Plus the insulation prevents water condensation rings.
If I am fortunate I wake up to the hammering of a night time downpour on the aluminum porch roofing. Then I go outside and wait for the inevitable micro burst downdrafts that bring chilly air. After the cell passes back to bed.
Never have a "porch light" next to a door or window, because that's just plain nuts. From short distance have a light play on the door. This keeps bugs at bay.
No need to get fancy with the lights just flop one down pointing straight up. I am one over the table then futz it around with my foot. Three of four feet of lamp cord and a couple of clips connect it to the battery. Connections reversed? Big deal, reverse them and the light will light up. I have a series of four, kitchen, bathroom, dining room and bedroom, the lamps are tiny.
A tad over five bucks each and they are waterproof and damned hard to break. No tax no shipping. These lamps are genuine CREE and the light never varies from 10 volts to 30 volts. Their light output is insane.
In an RV rig, a 20' tiny 20 gauge wire won't come close to being too small. This saves your batteries and you can stretch it outside. Place it FAR AWAY from where you are sitting and enjoy bug free relaxing.
