Why Do People Need Solar Phone Charger?

Mobile phone with solar energy charger

A solar-powered phone charger is a gadget that charges batteries without using a power source using sunlight. These are simple to use and therefore do not require much care. 

Solar cells capture the sun’s energy and convert it to electrical energy in this device. The primary benefit of using such a photovoltaic battery pack is that it can collect energy for future use when the sunlight is not accessible due to rain or clouds. 

You may charge your cell phone’s battery without exposing it to the sun. During the day, you can store solar energy in the solar charger and then utilize it at nighttime.

A solar charger is easy to carry, allowing you to charge your device’s battery anywhere. 

The primary advantage of utilizing this charger is that it allows you to charge your device without using an external power source. 

It comes in handy when doing outdoor adventures. You can take it with you when you go out for picnics or a gathering with your pals. 

Using this unusual charger, you may stay connected with your friends and family members when you are away from home and do not have access to a power source to charge your gadgets.

Buyer’s Guide: What To Look For In A Good Solar Powered Charger

What To Look For In A Good Solar Powered Charger

All the features and characteristics are discussed below to be looked at whenever selecting a Solar Power Charger.

Size And Portability

The first consideration is how you will move the photovoltaic power. 

Metal clips that can connect the gadget to a backpack or hang it on a camp are provided on certain devices, but some do not support this.

The size of the USB solar charger is the second consideration. 

Uncovered proportions are necessary to understand how much surface area is required to charge numerous devices. 

On the other hand, Folded measurements are critical because they provide a reference for how much space you’ll need in a backpack or tent.


The gadget’s weight is one of the most significant factors to consider when selecting a portable solar smartphone charger.

The weight will become less or more relevant depending on the outdoor activity you wish to conduct. 

If you’re looking for a solar phone charger for camping, for example, a lightweight device isn’t as important.

Safeguarding And Protection

Considering the type of hobbies and the area in which the mobile adapters will be used, 

Possessing a weather-resistant solar energy-based charger is an essential critical feature to consider.

Many models feature a PET polymer-based coating that ensures the solar chargers are protected from any possible wet or drop in harsh environments. 

Take a peek at the following feature. Also, if you plan to go kayaking, fishing, or sailing, make sure the goods you purchase are waterproof.

Efficiency Or Output Power From The Charger

The specs are the next thing you should look at. Portable solar panels must be highly efficient. 

It is a factor where you cannot cut costs because doing so will always result in underperformance.

Effective efficiency should be between 19 and 25 percent. 

In this scenario, buying brands that employ solar panels made by even the most effective product in the market,

(SunPower) is usually a good choice because you’ll get more power.

Accessory And Functionality

The accessories that come with the solar cellphone chargers are another vital feature. 

Is there a singular USB port on it? 

Or how about two USB ports? 

Is there any kind of connector included? 

Is there a built-in LED light or any other built-in features?

Cigarette burners, overcharged or short-circuited safety or a solar energy bank are all common extras or features that customers love.
