Selecting the Right Solar Panel Backpack

Considering the following factors will help you pick the right model of solar backpack for your particular needs. Once you have considered these things, it will be easier to choose the right product.

Device voltage and usage

Not all solar-powered backpacks have the same specifications. Some of them will have a specific voltage that might be higher or lower than that of your devices. The best way to know if it has the right voltage is to first check the devices you always use like your smartphone or tablet. Then, see if the battery pack included in the backpack meets their requirements. If your gadgets are USB-powered, then they require a 5V charger.

Are you going to use the bag daily? Then you should take note that most battery packs are not capable of charging and discharging.

If your device needs immediate charging, make sure that you have stored enough power in the battery pack or the solar-powered backpack allows direct charging, which means you can connect a cable directly to the solar panel. This is especially useful when the battery pack runs out of power and your only option is to directly charge from the solar panel as it collects and converts solar power. The best way to avoid this is to find a solar backpack that allows direct DC charging of gadgets with a proper connector.

Battery pack power capacity

Solar-powered backpacks were originally meant to recharge devices rather than fully charge them, but that doesn’t mean you can’t fully charge them. You just have to make sure that the battery pack has a large storage capacity to provide enough power for one or two of your gadgets. Experts say that the battery pack should have 5% to 10% more power capacity. Aside from this, you also have to make sure that the battery pack is fully charged first to ensure that it can fully charge other devices.

Solar panel adjustability

Sometimes the backpack’s position does not allow the solar panel to catch the sunlight, especially while you are walking. If you want to maximize the amount of power produced by your solar panel, make sure it is detachable. This way, you can adjust the position of your panel so that it is exposed to as much sun as possible.

What to Look for in a Solar Panel Backpack

Can Charge Laptops

There is no guarantee that a heavy-duty solar-powered backpack can fully charge a laptop, but if it offers 3 hours of power that should be enough. Not all backpacks can do this, so if your solar-powered backpack has this capacity, it means it will also function better overall and be a better source of energy for smaller devices.

However, backpacks that can charge laptops will be more expensive than others. Another thing to check is that your laptop can receive power from an external source rather than a power outlet.

Tough and Rugged Design

If you are going to explore the wilderness or the mountains, then your backpack should be tough and rugged. It should be able to withstand outdoor conditions whatever the season. Aside from that, it should have the ability to handle heavy loads, especially if you are going to be out for days or weeks.

Lightweight and Comfortable

Not only should your solar-powered backpack be tough and rugged, it should also be lightweight and comfortable. The overall design should be ergonomic so that you will feel supported while carrying a heavy load. It should also have straps with padding to make your shoulders and back feel more ease.
