When choosing a portable generator for camping, it's important to consider your power requirements. Determine the wattage of the appliances and devices you plan to use and add them up to get the total wattage needed. Choose a generator that can handle at least 20% more than your total wattage requirement to ensure it can handle any surges or fluctuations in power demand. Additionally, consider the weight and portability of the generator, as well as the noise level, to ensure it's suitable for camping.
