  • Unlike batteries or other power sources, solar chargers are much more environmentally friendly since they are using a renewable energy source.

Cons of Solar Chargers

  • Unlike a power bank, most solar chargers are much larger in size making them a less portable option.
  • Solar chargers will not work at night, on a rainy day, or in areas which do not get a lot of sunlight.

Similarly, a 9 inch x 4 inch x 6 inch power bank will be more portable than a 12 inch x 5 inch x 9 inch one.
  • Charge Capacity: Unlike a solar charger, all power banks will have a specific charge capacity which tells you about the maximum amount of charge or electrical energy they can store inside. For the same, you can find charge capacity ratings like up to 10000 mAh, 20000 mAh, 30000 mAh, and even higher where a higher charge capacity will allow you to easily charge your mobile device multiple times.
