Buying Guide

Watts

Most solar backpacks are equipped with 5W to 12W solar panels. Finding a bag with a solar panel of higher capacity than 12W is rare, and any panel of less than 5W is relatively useless as charging your devices will take too long. Ultimately, the higher the watts, the quicker the rate of charging.

Battery Power

Many solar backpacks will come with a built-in battery others will only have a USB port. The size of this battery also varies; some may be able to charge your smartphone once while others may be able to charge a laptop.

Size

The bulk of standard solar backpacks are about 20-25L. This is enough space to hold your charging tools and the necessities. Be conscious that the larger the bag and panel the greater the weight on your back. A lightweight solar backpack is good for normal everyday commute and for quick day hikes. But if you’re going to do some extreme trekking, what you need is a bigger solar backpack.

Durability

Also critical is the overall quality of the backpack and the solar panel. Poorly built bags will not hold up when used every day, putting your expensive electronic devices at risk. Likewise, exposed or poorly-made solar panels can be easily damaged and will most likely fail. During emergency situations, this inconvenience can become more serious.

Budget

Price is always an important factor in the outdoor gear decision-making process. Between the cheapest and the most costly solar backpacks, there is a significant price gap. This requires weighing the pros against the benefits. Usually, a higher price corresponds to better quality, higher longevity and often lower weight.

Frequently Ask Questions

Can you charge a laptop with a solar backpack?

Few solar backpacks are capable of charging laptops but not all of them. It just depends on your battery system and whether it can handle a laptop charger. Some backpacks come with battery banks, but only Voltaic Systems Array Rapid Solar Backpack Charger can accommodate a laptop. Alternatively, you should buy an external laptop battery and connect it up to your solar panel with high wattage.

Is it safe to wear your solar backpack in the rain?

Typically light rain on an ordinary backpack does not harm the solar panels. Many solar backpacks come with some sort of weatherproofing, but not all are waterproof at 100%. Although the brand may suggest that the backpack is waterproof, it is always safer to be careful than regret it later. A rain cover on the backpack is inexpensive and can conveniently fit over your bag, shielding your delicate electronics fast.

How long do solar backpacks last?

Construction efficiency and amount of usage decide a solar backpack’s life span. Backpacks you wear for a regular basis won’t last as well as many you take for casual excursions. Naturally, solar panels decay per year too, but typically at a very small pace. Many solar panels last for years unless otherwise damaged. Some solar backpack companies provide warranties for their bags which will make your mind feel relaxed. Typically, such guarantees are 1 year, which will cover production defects, corrosion, or other specific solar problems.
