How to Choose the Right Solar Laptop Bag
Solar Panel Wattage & Efficiency
The wattage of the solar panel is arguably the most important factor. Higher wattage (like the 40W option) means faster charging, especially for larger devices or in less-than-ideal sunlight. However, wattage isn’t everything; efficiency matters too. Look for panels using monocrystalline silicon (as seen in some models) as they generally have higher efficiency rates (23%-25% is good) than other types. A higher efficiency means more of the sunlight hitting the panel is converted into usable electricity. Lower wattage panels (5W-14W) are sufficient for small devices like phones, but may take significantly longer to charge a laptop or power bank. Consider your typical charging needs and how often you’ll be relying on solar power.
