How to Choose a Solar Powered Backpack – 3 Key Features to Look For
Solar Panel Specs
The wattage of the solar panel will tell you how long the PV module will take to charge your devices. A higher wattage solar cell (between 7-10 watts) should be enough to charge bigger electronic devices in a faster period of time.
The other factor is the efficiency of the cell. If you own an RV and you are considering going solar, you might be able to choose larger solar panels for RV’s with lower efficiencies.
However, for solar backpack purposes, you will need at least 18% efficiency.
The second factor that should be taken into account is the battery pack included inside the backpack.
The capacity of the power bank will be crucial to give you an idea of how many charges you will have for your electronic appliances. Also, you must look into the number of USB ports, charging possibilities (from solar and AC) and speed charging times as well based in the technology of the battery.
Finally, the last factor that you should take into account is the number of compartments that you will have available for storage. The capacity of storage also gives you an idea of how big is the solar powered backpack.
Check to see if there is a laptop/tablet sleeve and side pockets for water bottles or umbrellas.
Why You Should Buy a Solar Panel Backpack for Your Next Hiking or Camping Trip
To have the best time in your hiking or camping experience, you must also think about gear and equipment.

Therefore, having a solar panel backpack that combines high-quality gear and equipment storage with electricity production is a great resource for any hiking, camping, or school experience.
