Camping doesn’t mean you have to give up the comfort and safety at home. The use of portable solar panels to charge mobile phone batteries and power electric equipment is a safer and more environmentally friendly camping charging method so far.
So first of all, what size of solar folding bag is suitable? The answer still depends on what kind of camper you are and what charging equipment you plan to use during your trip. If you are a backpacker, you just need something to keep your mobile phone charged and power the LED lights at night, then a small folding bag (about 30W) is enough. One is that Backpackers need to ensure the function and lightness at the same time.
On the other hand, if you are an RV camper, like to take home electrical equipment and do not mind building a solar panel system in the camp, fixed or folding solar panels are a better choice. These solar panels have a high wattage (100-200W) and can provide power for charging equipment for a long time.
If you need a solar folding bag with accurate wattage, you can use the formula to calculate it. First, you will use each electrical device within 24 hours. This will give you the total ampere hours required per day (ampere hours = ah). If you need to supply power to the 12V 5Ah camping lamp, the camping time is 6h. Therefore, through calculation, 12 * 5 = 60 wh, 60 / 6 = 10watt. However, due to uncertainty, the general power will exceed 20% of the calculated power, that is, 12W. If it is a larger electric appliance, remember to use it with the converter to ensure the safe and stable output.
