Comparison of four charging methods of portable power supply
1. Mains charging (household socket)
Speed: the fastest, usually 2-6 hours full.
Convenience:
Cost: lowest
Application: daily household use, power supply before camping, and indoor emergency.
Conclusion: It is the most stable, common and practical.
2. Car charging (cigarette lighter)
Speed: slow, usually 8-15 hours.
Convenience:
Cost: low
Application: charging while walking on the road, short-distance emergency
Conclusion: supplementary charging is ok, but it is not suitable for being the main force
3. Solar charging
Speed: It is greatly influenced by the weather, with 6-12 hours on sunny days and slower on cloudy days.
Convenience:
Cost: medium (solar panels are needed)
Application: outdoor long-term camping, no electricity environment, emergency power supply.
Conclusion: The outdoor scene is the most practical, and the home is average.
4. Generator charging
Speed: fast, close to the mains.
Convenience:
Cost: high (oil+noise+maintenance)
Application: extreme power-free environment, high power and long-term power consumption.
Conclusion: Ordinary people basically don't need it.
Final conclusion (one sentence summary)
Daily household/emergency: mains charging is the most practical
Outdoor camping/no power grid: solar energy is the most practical
Charging on the road: car charging is the most convenient.
There is absolutely no need for ordinary users to use generators.
