Answer
A G.P.S. for the jeep. Hiking boots. A backpack. Portable D.V.D. player. Survival kit for jeep. Camping equipment. Go to any good outdoor sporting supplier and ask a salesperson. Preferable a guy.

Im going camping and its quite hot, is there a battery powered outlet i can plug a fan into?
By that i mean is there a battery powered outlet I can buy at a store.
Answer
Many manufacturers make portable 12V power packs you can recharge at home or in your vehicle and then run small items like a fan, lighting, laptop, satellite phone, etc for several days before recharging. They feature a 12V accessory outlet like the cigarette lighter outlet in a vehicle, and a built-in, rechargeable battery. Many also include a 120V or 240V AC outlet (depending on the standard in your country) with the necessary inverter circuit to convert DC to AC power. Xantrex, Wagan, Duracell, Diehard, and RoadPro are some of the name brands to consider.
The key to selecting a power pack is to know how much power you need for how long. For example, if you are going to run a fan for 8 hours per day that draws 0.5 Amps you will need 4 Amp/Hours per day (0.5 x 8), or 20 Amp/Hours for a 5-day stay (8 x 5 = 40). Likewise, running a laptop that needs 1 Amp for 4 hours a day during a 5-day trip will need 1 x 4 x 5 = 20 Amp/Hours.
Smaller power packs are rated in mAh (milli-Amp hours), so you need to divide by 100 to convert to Amp Hours (e.g., 2500mA/hr = 2.5A/hr); these units are usually only good for recharging cell phones or MP3 players. Some power packs are rated in Watts instead of Amps; to convert you divide by the voltage, in this case 12 for 12 volt units, so a 600 Watt unit would yield 50 Amps (600/12=50). Likewise, some appliances are rated in Watts, and you use the same formula (Watts/voltage) to convert to Amps.
While the units that can run 120V or 240V AC appliances might cause you to consider bringing a standard household fan, understand that the conversion from DC to AC will eat some power due to circuit inefficiency, as much as 40%. So sticking with 12V DC appliances would provide better run times.
12V portable power packs are available at Sears, WalMart, and many other local retail stores, as well as on-line on Amazon and many other ecommerce sites. They range in price from $40 and up, depending on the brand name, capacity and features. Understand that these units are very heavy due to the weight of the batteries needed to provide the capacity, so this isn't something that would be usable for backpacking. Making one yourself from a 12V deep-cycle battery (aka "marine battery"), clip-on cigarette lighter outlets and a suitable container is not difficult.
12V DC Fans are also widely available at auto-parts stores and truck stops, as well as on-line.
I have a small 12V power pack I bought on close-out at Walmart for $25. I use it to run a 12V refrigerator at camp while off driving during 4WD trips, simply recharging it from the Jeep when I return to camp.
