Hiking, traveling, and going on an adventure off-grid is exciting, but it poses a challenge: how will you charge your device, phone, or laptop?
Without a power station, your devices can go off when taking important photos of important scenes! Your phone can also shut down in the middle of nowhere, leaving you stranded in the jungle.
While you can carry a power bank, it also needs charging. So, no guarantee with a power bank. What about solar battery backpacks? Are they worth buying, and can they help you off-grid? And what are the top solar-powered backpacks on the market?
These and other questions are answered in this article. Let’s dive in.
You might also wonder whether you can charge a power bank with a solar panel; I wrote a whole article that I encourage you to read.
What Is a Solar-Powered Backpack?
We all know a backpack for travelers, hikers, and business persons. Now, you can imagine a mini solar panel mounted in front of the pack, making it a solar-powered backpack.
Solar-powered backpack allows you to charge your devices anytime, anywhere. You don’t have to carry a separate solar charger or a solar power bank on the side. You can connect your phone to your backpack and charge it as you walk, hike, or camp off-grid.
Here are the solar-powered backpack’s components
- Flexible solar panels
- Solar battery
- Charge controller
- DC-DC voltage converter
- Emergency bulbs
What Does a Solar-Powered Backpack Do?
Thin-layered solar panels are counted in front of the backpack, and when exposed to sunlight, the panels absorb the energy and convert it to electricity. The electricity is given a DC voltage output supplied directly to your device or stored in a battery for future use. The batter is built-in into the backpack, but the charge controller controls the storage process.
The solar backpack battery is lithium-ion, which means that a full 10-hour charge can store the energy you will use for up to 55 hours.
When you want to charge your device, the panel or storage battery power goes through a DC-DC converter to step down the voltage to meet your device’s needs.
You can use solar bags to charge your mobile phones, iPad, digital camera, and other electronic products. Besides traveling and mountaineering, you can use solar-powered backpacks on a business trip.
A solar-powered backup without a battery or charge controller means that the generated electricity should be used immediately. During cloudy days or at night, you cannot use your backpack to generate electricity.
They are convenient to carry, integrated with the luggage, safe to use, and simple to operate.
Advantages Of Solar-Powered Backpack
As we have already pre-empted, solar bags have several advantages, including
- The batteries and the bag are integrated; hence no need to carry power banks or backup batteries. You don’t need to sweat over extra space on your travel bag to carry chargers.
- You can charge your device wherever you go. No need for power stations to charge your devices.
- You can go off-grid without going offline; hence suitable for wildlife photographers, hikers, and travelers.
- Solar-powered backpacks are environmentally friendly since it does not release greenhouse gases to the environment when generating electricity.

Disadvantages Of Solar-Powered Backups
All is not rosy with solar-powered backpacks. Here are some challenges for solar bags.
- Solar-powered backpacks are more expensive than regular solar chargers, power banks, and backup batteries.
- Solar-powered backpacks rely on sunlight to function optimally. With high-intensity sunlight, your solar-powered backpack will not operate efficiently, providing less electricity during cloudy days.
- The design does not suit everyone, with some complaining that the backpack designs are uncomfortable.
