What is a solar power bank?
A solar bank integrates a solar panel directly into a battery. The panel captures the sun’s energy; the battery stores it. Most solar banks can be plugged into a wall outlet in the event that you need to charge the battery when there is little sunlight.
Solar power banks are vastly different from rooftop solar arrays and solar generators. Solar power banks are generally much smaller and more portable.
They can be used to power small appliances such as phones, tablet computers, PlayStations, boom boxes, calculators, and other electronics.
In general, something that can run on just one or two batteries can be charged with a solar power bank.

How does a solar power bank differ from a solar phone?
The technology to power a wireless phone with solar has been around since 2009. However, the first solar phones did not meet the needs of the many. They took too long to charge and provided far too little time to talk.
Today, people rely on their mobile phones to do a wide variety of things. Phones need to give us a solid connection to the internet while also being cameras and flashlights.
Solar phone technology was sidelined in favor of solar power banks that can charge faster and provide longer use of the phone. They are especially useful in that they can charge more than one phone at a time.
Solar phones may still be useful as emergency backups. But for camping and rural living, a solar power bank is more useful and versatile.
Another way to keep your phone battery full is to use a solar-powered phone case. Check our round-up review of solar phones cases to learn about the best options on the market.
Who needs a solar power bank?
People who are often or always on the move often need solar power banks. Hikers and bicyclists can hang them from their backpacks and charge them while on foot.
At night they can call friends and check for local amenities on the solar-charged devices.
People who live in very rural conditions, miles away from another house or business, will want to own solar power banks. Hurricanes and avalanches can knock out power, leaving someone alone without a way to call for help.
Long road trippers may also benefit from solar power banks. With one of these lightweight appliances, you don’t have to drain your car’s battery to charge your phone.
And solar power banks can even be used to jump-start a dead car!
Campers may benefit the most from the simplicity of the solar power bank. You camp to get away from it all.
But you still need your phone’s GPS and the ability to call for help, no matter how far into the wilderness you wander.
How do you use a solar power bank?
Most solar power banks are extremely lightweight and weigh less than a pound. That makes them easy to travel with.
These solar power banks can be charged from inside a building if you leave them in a window that gets a lot of sunlight. However, you are unlikely to get the fullest charge that way.
They work best when charged outdoors and on sunny days. Many of these solar power banks fold out into a sort of pentagon or hexagon. Need to know how solar works with the weather? Read our guide on how solar panels work in weather conditions.
You unfold the panels into a semi-circle and lay the structure on the ground, with one panel touching the floor on one end and another touching the floor on the other end.
You can also lay your solar power bank across your pack and just let the panels fall on either side.
Arranging the panels in a pentagon or hexagon allows them to absorb as much sun as possible from several different angles.
You will have to be careful about what surface you place your solar panel bank on. Some of them cannot be safely charged on a concrete surface or a car dashboard.
Under certain circumstances, solar power banks can overheat. That damages the apparatus.

What should you look for in a solar power bank?
As you are shopping for a solar power bank, carefully consider what you need it to do. Do you need it to power your phone for more than ten days away from all electrical power sources? If so, you will need a solar power bank with a large battery and heavier panels.
Do you need your solar power bank to serve as an emergency flashlight or beacon? Check for that feature.
How many devices will you need to plug in at one time? Most portable solar power banks are good for charging one or two devices simultaneously. But others can charge as many as four devices.
Are you going to have periodic use of traditional electricity? Many campers and hikers move between primitive and full-service campgrounds.
If that is the case, consider a solar power bank that can also be recharged by plugging it into a wall outlet.
You may only need solar power when you are at a primitive campground with no electrical outlets.
Then, when you rent a cabin, you can recharge the device with regular electricity.
Also, check the warranty and return policy for your solar power bank.
If the first one you get does not meet your needs, you can often return it for a full refund and try another.
