Solar phone banks vs. solar panels

Later, you can use USB cables to transfer the energy to your phone or other devices like flashlights and others. Or, you can store the energy in the solar bank for later use. On the other hand, solar panels are devices that offer an instant transfer of energy. The energy from sunlight gets transferred in the solar cells and reaches your device directly. Thus, there is no intermediate storage.

Solar banks sound more convenient but are bulky for your travel backpack. And, if the day turns out to be too cloudy, your panels are almost useless. Solar banks are quite slow in charging, especially when you are not in a sunny destination. Since the solar power is stored in the cells of the power bank, the output will be consistent. On the other hand, the panel’s output can fluctuate based on the sunlight availability. Moreover, in a solar bank, you are storing energy in a cell and then to your phone, which leads to a little energy wastage.

Which is the best option? Avid campers carry both solar panels and solar bank. Whenever there is direct sunlight, they would use the panel to charge their devices and the bank. On darker days, the bank would be a good companion.
