For USB port connections, you can use either the standard USB port or a Type C port to connect your charger to the panel. The USB is located on the outside of the bag with a water-resistant cover for ease of access. 

In fact, the whole bag is water-repellent thanks to its polyester makeup. What’s more, the bag is made from recycled plastic. Ultimately, the XD Design Bobby Tech Solar Backpack is designed to ensure your items will stay dry and protected.

“ECEEN

Specifications

On the days where there is no sun out, you may want a battery pack to store extra power. Jauch suggests using a battery intermediate when using this bag.

Buying Guide – How to Choose the Best Solar-Powered Backpack

There is a lot to think about when you are looking for the best solar backpack. You need the pack to do everything a standard bag would do. You want it to store your items, keep them safe, and be easy to carry. Aside from this, the solar panel aspect has a whole list of criteria in itself. 

Here’s a list of the most important things to consider before buying one of the best solar backpacks of this year. We’ll break them down in more detail below.

  • Material 
  • Solar panel wattage
  • Type of USB
  • Weight
  • Pocket sizes and configuration

Solar Backpack Material 

Material plays a big part in your backpack. Both the interior and exterior materials matter, though often they will be the same. Finding the right material will help make the bag more durable, lighter, and more comfortable. 

Here is a list of the most common materials to look out for, and why:

Polyester: is durable and lightweight. It’s also usually water-resistant, so it’s great for longer trips or outdoor adventures. If you can find polyester made from recycled plastic, then that’s also a big bonus for the environment.

Nylon: is tough and durable. It’s more than effective on its own, but sometimes it’s blended with poly fabric to make it extra water and tear-resistant.

PVC fabric: is lightweight, as well as water, and tear-resistant. This is a great option for those who are serious about comfort.

As you’ve probably noticed, all of these materials are water-resistant. Waterproof solar backpacks can help you keep your stuff dry, even if you’re walking in the rain. Most bags are at least water safe, but some do a better job in the elements than others. Make sure you know the difference between waterproof and water-resistant (or water-repellant).

Water-resistant fibers are coated with a hydrophobic compound to repel water. This helps to keep your items safe in harsh weather (2).

Solar Panel Wattage 

Theoretically, more energy from sunlight hits Earth in a mere 1.5 hours than the entire world consumes in a whole year (3). Any walk you take on a sunny day can indeed power your devices if you can collect that energy.

The best solar-powered backpack should be able to charge your devices whenever you need it to. For phones and tablets, anything over five watts should be fine. 

Before you even start looking for a bag, you have to consider what you want to charge with it. Not every device requires a backpack with the highest wattage. Here is a small run-through of what wattages can do for you:

  • 1 watt – 5 watts: This is great for smaller devices like phones and digital cameras
  • 5 watts – 10 watts: This is great for charging phones fully or partially charging tablets and laptops

To power more wattage intensive equipment, you can look into portable solar panels, extra batteries, and grid-tie inverters (for residential use).

Type of USB on the Best Solar Panel Backpack 

When you’re using your bag, you want to make sure that your charger can plug into it without adapters or other pieces. Some bags offer standard USB and some offer the USB C style (4). 

The best solar panel backpack offers results for both USB styles on their bags. This feature could be helpful if you use multiple chargers, or if more than one person will be using the pack. 

Weight of the Solar Backpack System

Being able to carry your pack comfortably is essential. Your backpack will be following you everywhere you go, hauling around all your items. Whether at school, the office, or even out on the trail, weight is a crucial factor to consider when buying a backpack.

Ergonomics and weight management are core qualifiers of what makes a good pack, including those with solar charging capabilities. Even the best solar backpacks can be uncomfortable to carry for long distances if they’re too heavy.

Experts suggest that your backpack weighs no more than 10% of your body weight (5).

A standard bag, when it’s empty, will weigh one to six pounds. You can use this as a baseline and make sure that your solar backpack doesn’t weigh much more than that. 

Pocket Size and Configuration for a Solar Backpack

Finding space to bring everything you need is essential. When you’re looking to buy one of the best solar backpacks, you want to make sure it is big enough to carry your items and all your items have a spot.

A bag that you can customize allows you to make the space you might need. It also helps if the bag has pockets and storage features for specific items. 

It may not be the most flashy feature, but a bag has to hold your items, or it won’t be an excellent option for you.   

FAQs

 Yes, solar backpacks can be very safe. As written in Dr. Sean White’s Solar Photovoltaic Basics: A Study Guide for the NABCEP Entry Level Exam,

“Solar power is a safe form of nuclear energy. We are using fusion reactions that are 93 million miles away to make light that we then convert to electricity with photovoltaic modules.” (6)

However, some packs have batteries, which could be slightly hazardous (7). With the backpack, you will want to make sure that there are no exposed wires. You will also want to make sure the bag doesn’t get too hot while in use.

Of course, you can make your own solar backpack. If you decide to undertake that mission, you are going to want to find a guide or instructions (8). You will also want to pick the right materials and install them correctly. 

Be careful if you try to build the backpack yourself. You don’t want to make hazardous wiring mistakes or assemble incompatible electrical components.

Generally speaking, solar backpacks work by utilizing small, lightweight, and portable solar panels that are attached to the outside of the bag where they can receive light (9). With these solar panels, they absorb the sun’s energy to help power your devices.

In most solar panel backpacks, the panel is able to bend to make it easier to use on the pack. Also, it can be placed in a clear but waterproof pouch that can keep it safe and dry.

The amount of power you need will depend on what equipment you’re looking to power.

Many of the backpacks don’t come with a built-in battery, so you will want to make sure that the solar panel gives a high enough wattage to charge your phone or device directly. To charge many phones, it only requires five watts.

More wattage may be useful for charging other devices like power stations. In addition, higher wattage panels will work in a broader range of situations.

In our books, yes, solar backpacks are worth it. Solar backpacks allow you to use the free and abundant power source, sunlight, and charge batteries, phones, and other devices.

The peace of mind you get knowing that you will have a charged phone on every trip is critical. It will also let you keep your device on so you can use it when you need it. This means you won’t have to ask to plug in somewhere or be stuck with dead batteries when you need them.
