If you want to use electricity for a long time in nature, you can use solar paper.
Solar power generation paper is a portable and foldable solar power generation product manufactured using thin film solar power generation technology. This product is suitable for outdoor emergency power generation, rescue and exploration, and provides electricity wherever there is light.
Can generate electricity outdoors under sunlight to charge mobile phones, iPads, digital cameras, power banks and other devices. Its shape resembles that of paper, hence its name: energy production paper. Its power is 8-97W, of which 8W can charge an iPhone 6 in 3 hours, and 97W can be used for outdoor rescue, yurt power generation, etc.

I think what everyone said above is too irresponsible. Also keep wasps away. . There are no more bees, but aren't the wasps more powerful?
Bee repellent: Benzaldehyde and propionic acid or carbolic acid can be used. Benzaldehyde and propionic acid repel bees. First nail the wooden frame with wooden boards, nail 6-8 layers of black cloth on top (sprinkle 1:1 water and benzaldehyde or 1:1 water and propionic acid on the fabric), then nail a layer of iron sheet and paint. surface black paint (used to absorb heat, the principle is similar to solar energy, to evaporate pharmaceutical agents) to increase the absorption of heat from the sun andevaporate the repellent, which can effectively drive away bees. Or use vinegar instead. The effect is not as good as the above, but it can still achieve the effect of eliminating bees.
