MotorMachineMercenar wonders: "I just took a roadtrip over a long weekend and noticed that I need to lug around too many chargers. I have a charger for my cell phone, Nintendo DS Lite, my two digital cameras and an iPod. Sometimes I will have one for a portable HDD and laptop. In addition I have to carry a plug converter as some of them have been bought overseas. That's up to eight gadgets just to give juice my power-hungry devices, and they take precious space and weight in my bags. Is there any way to limit the number of chargers without gimping my roadwarrior gear? Most devices have more or less fixed batteries, 'smart' chargers and proprietary plugs, but is it possible as DIY, or is there an existing product? I'd like to see a universal charger for which plugs for any current device with the flexibility to add more in the future. What are the limitations and caveats with 240 vs 120, wattage, cutting and connecting cables, and so forth?"
