What Is A Solar Energy Bank?


Sharing is caring!

As its name suggests, the solar energy bank the-best-solar-power bank-for-mobile-phoneis an electrical energy storage device that charges via solar radiation. These devices are particularly useful when you go camping, or hiking and you can not always have the electrical energy sector at hand.

The solar energy bank is composed of an electric energy storage battery and one or more small solar panels. In addition, it has one or more charging ports for different mobile devices. Easy to take away the solar powerbank comes in foldable version or pocket version.

Who should buy a solar powerbank?

Anyone looking for an environmentally friendly solution to charge their mobile devices can get a solar powerbank. If you also want to stop using these electric energy banks that must be recharged every night, you can consider the purchase of a solar powerbank (solar powerbank test).

As it is portable, compact, suitable for many mobile devices, requiring only the sun’s rays to walk, the solar powerbank is particularly useful for people who travel. More specifically, it is a reloading device that can be used in the wild as soon as the sun is optimal.

So, we can all use the solar powerbank. However, people who do not have an electric power source at their fingertips are most encouraged to purchase this device.

How to choose the best solar powerbank?

Fans of outdoor activities these days are better off than those of yesterday. They have at their disposal various electronic gadgets that allow them to perfect their activities, including GPS. This tool is now available on our smartphones.

The only small problem in this story would be the intensive use of the device that may not be suitable for its battery. Fortunately, renewable energy professionals have invented the portable solar powerbank adapted to several nomadic devices. So how to choose a portable solar powerbank?

Intensity, voltage and watts

You must first understand the technical terms associated with your solar powerbank to be able to define your real needs. To find your way around, think about how the plumbing works.

Here is the little note of reference concerning: tension = pressure of the water; current measured in amperes = water flow and resistance (ohms) = size of the water inlet pipe. So, the electric current delivered by the device. Then, the current that is measured by ampere is equal to the voltage divided by the resistance. In addition, the watts correspond to the measurement of the electrical power which is defined as the voltage multiplied by the current. Watts and amps are the most common units you will use and need to understand to decipher the potential and performance of your solar panel. Again, this is electrical current and power .


A panel of 4 or 5 watts is enough for small nomadic devices. However, devices like smartphone and tablet are a little more energy consuming and require a power of 7 watts. If you plan to charge more than one device from your solar powerbank, you will need a minimum power of 15 watts. If you plan to charge a laptop, you will need an inverter and a battery. For charging AC peripherals, you will need a 25-watt solar panel, a battery and an inverter. However, whatever your type of consumption, we advise you to choose a solar powerbank (solar powerbank test) with the most powerful panel to enjoy a fast loading .

Output power

The output power of your solar powerbank must match the demand of the devices you are going to charge. If you take a device with two charging ports, make sure that the manufacturer tells you the output power of each port separately. Take the example of a device that indicates a combined output power of 2.1 A. In this case, you will get an output power of 2.1 A and another at 1 A only . With such powers, you will have to wait a long time before seeing the battery of your nomadic device full charged.

You must also consider your location point. If you are in a place where the sun is never quite present, take a very powerful device. Otherwise, if you find yourself in the desert for example, you could take a pretty average device. In addition, if you leave only the time of a weekend, a solar powerbank will suffice you. If you plan on going for a long-stay nature adventure, opt for devices with panels, and batteries for storing electrical energy.
