A few years ago I was lucky enough to buy a few cans big enough to fit a 5,000 watt power inverter wrapped in cardboard. I also picked up an over-sized steel drum from Sportsman's Guide that fit a 2200 watt inverter generator in its cardboard box. Popcorn tins have various items used for solar power as well.
