Advantages of Solar Chargers
Emergency essential: As long as the sun is shining, you can charge your or other devices without a power source.
Clean Energy: Solar panels use solar energy to generate electricity and are the cleanest and greenest form of energy on the market. You don't need any type of fuel and they don't have any impact on the environment.
FREE ENERGY: Besides being green, they also save us money. Once you pay for the equipment, you don't have to spend a dime to generate your own energy.
shortcoming
Climate impact: Solar chargers rely entirely on solar energy, and of course, they can also work on cloudy days, but their efficiency is greatly reduced. It depends on the part of the country you live or travel to, cloudy, foggy, and the same problem at night.
Slower: Despite advances in technology, charging with a solar charger is often slower than charging with a traditional outlet. Relatively speaking, a charger with high power charges faster.
Space size: Solar chargers are collapsible, but they still take up room in your backpack.
Fragility: When traveling outdoors, the surrounding environment is complex and changeable. The single crystal silicon used in the charger is very thin and easy to break.
