For the gearhead on the go, a solar backpack is an absolute must! With the ability to hike in the beautiful sunshine while creating electric power for your phones, tablets, and laptops, you can enjoy nature without giving up your devices.
Even a camping purist, who wishes to escape from the constant beeping of their cell phone may find it hard to resist this eco-friendly product. The ability to charge up GPS devices, and electric lights, is just one of the many benefits of carrying a backpack.
Like most backpacks on the market today there are quite a few options for you to choose from and each solar backpack has its own special features. In this article, we will cover how to select the best solar backpack and discuss a few necessary requirements the back you choose should have!
Output Power, Amps, Watts, Etc
When you are out to buy a new backpack with solar charging abilities, you first want to do a little research into how the bag charges, and more importantly what it charges. Devices require different outputs, different efficiencies, and even different ports to plug into.
Make sure that the solar backpack you choose will charge your desired electronic, whether it’s a smartphone, tablet or handheld GPS device. Below we will walk through some of the specs, and what they mean.
The spec to look for when you are shopping for the output power is the total amperage of all the ports combined. Output power is the maximum output, and certain phones, especially our beloved smartphones require more output than others.
When you are looking at the output power you are determining if it’s enough for your device to charge, and how long it will take for your device to charge.
When you buy your solar backpack a good rule of thumb is to get a backpack rated with 1 amp for a phone or 2.1 amps for a tablet. Backpacks are normally equipped with USB ports that you can plug your device directly into, however, you may be wishing to charge your camera’s batteries on the go, or even a full laptop, that requires you to have a wall port.
Purchasing an inverter can help, however, the adapters convert the power, and so there is a significant loss of power to the device with a solar backpack. Meaning it will charge slower.
Most bags will have 5V USB ports for you to charge your devices with, what you want to keep on the look out for is voltage stabilizers. Sunlight and the power it provides can be very unstable and fluctuates throughout the day.
Whether you are directly connecting your device to the solar panel or using a battery as a middle man, you will still want to purchase a backpack with a built-in stabilizer.
When you go to purchase a solar backpack keep in mind what type of product you plan to charge on the go to pick the right pack. Some will be more expensive because they produce a higher output power, so if you are looking to charge a camera or larger device, this might be the way to do it.
When you are studying the specs, keep in mind where you plan on taking the backpack, is it in the bright sunny desert? Or are you headed to a cold mountain, with minimal sun? These devices may not generate as much energy as you need for large devices, so at the end of the day, consider your budget, but also your devices and the location of your next trip.

Safety for your Shoulders and Back
A solar backpack is still a backpack, and with that, you are not going to want to skip comfort and safety when selecting a backpack. After you have determined if the solar strip has enough output power, amps, and watts, you are going to want to see if the backpack is worth carrying.
If this is the first time you are bringing your devices along for the camping trip, then you are going to want to factor in the extra weight. A good backpack is going to give you two main features: Support and Comfort.
When you are looking at the backpack to determine if there is enough support to be bringing along heavy devices and an additional solar panel, you want to make sure your shoulders and lower back are protected. The simplest way to tell is if there is adjustability for the full backpack.
Does it have should straps that you can let out, or pull in depending on weight? Does the backpack feature hip straps that take any additional weight of your shoulders and lower back? Pick a backpack that will best accommodate the load you plan on hauling, and has the most customizable options.
Support is not the only necessity, when you are traveling for long periods of time, being comfortable with your backpack is going to be a necessity not a luxury.
Make sure there is an appropriate amount of padding along the straps and back of your pack. Try the backpack on to make sure it is the right size, and then if possible find fabric that wicks away sweat from your back and shoulders, especially if you are going on sunny hikes!
Fast and Easy Use
The point of a solar backpack is to create an easy way to charge up your devices while out on the trail, it would defeat its own purpose if it was difficult to use. The last thing you want to be doing is messing with controls, charging ports, and the functionality of the solar backpack.
When you look through the gear reviews make sure that it both user-friendly and effective. Ideally, the solar panel on the backpack should be self-operating, and not constantly pulling your attention away from your surroundings.
The solar backpack allows for you to charge on the go more efficiently than if you were to bring a solar strip that you need to set up. By having the panels and necessary USB ports directly on the backpack itself, it saves you the time and effort of making sure that your position is right, and the charger is working.
It also saves you backpack space. Rather than dragging strips along to power your phone, and carrying the whole set up inside the bag, a solar backpack gives you the same roominess and storage in the pack while still protecting and charging you gadgets.
