This executive-style backpack looks sleek and can hold a 17-inch laptop in its main compartment. Flexible solar panel holds up better to pressure or drops than older, more rigid panels.

Powerbank output is not high enough to charge a laptop.
Roomy backpack fits up to two 15-inch laptops and has room for even more stuff. Solar panel is securely attached to the outside front. Style-wise, the pack’s OD green color makes it a good choice for hunters and preppers looking for a decent bug-out bag.
Fabric and zippers are a bit flimsy and may not hold up to rugged outdoor activities.
Solar backpacks come in very handy when traveling, especially when a power outlet isn’t readily available. A flat solar panel array installed on the front of the backpack absorbs sunlight and converts it into electricity, which is stored either in a battery pack or another device with a lithium-ion battery, such as a smartphone. Solar panels in general don’t convert light into wattage very quickly; most average 6 to 7 watts. Therefore, the most effective way to make use of a solar backpack is to charge all devices at an outlet before leaving on a journey and then to plug them into the solar panel to top up their charge during the trip. Look for a sturdy backpack that holds the solar panel securely in place so it doesn’t fall off.
