Solar chargers today, few people are surprised. If earlier they were quite expensive and even fashion devices, now it is a mass product. They can afford almost any user. The main advantages of solar charging are autonomy and operation even in ambient light. An important advantage is its versatility. Such devices can be connected to various types of phones, tablets, navigators, laptop players, and other devices.
To do this, manufacturers include a substantial set of adapters. At the same time, you need to understand that some solar charging on its power simply cannot pull charging devices with large battery capacity. That is, solar charging for the phone will not be able to overpower the laptop charging. The point here is both in the battery capacity and in different output parameters (charging current and voltage). In this article, we will try these and other parameters of solar battery chargers.
The principle of solar charging
The solar battery charger is completely self-contained and does not need an outlet. That is, such charges can be used away from the city, where there are no power grids. Nothing complicated in their use. To charge the mobile gadget you need a cable with a suitable adapter to connect it to the charger. And then find a position for the solar panel so that the sun’s rays fall on it. Of course, the charging speed leaves much to be desired.
Manufacturers of such devices talk about high charging speed, but most often it’s just advertising slogans. However, in field conditions, you may urgently need to make a call, and this does not require a full charge of the phone battery.
How to choose a solar battery charger?
When choosing a solar charger, you should take into account its capacity, output current, and voltage, charging methods, a set of interfaces, equipment, design, and materials. Below these characteristics are divided into two large groups and discussed in more detail.
The main characteristics of solar charging are the power of the solar panel, which determines the charging time of the battery. And also important are the capacity, voltage and charge current. Power panels in such chargers are small. As mentioned above, it takes a long time to charge the battery.
Capacity determines the amount of electricity that accumulates in the charge. It is measured in ampere-hour or milliampere-hour. The amount of capacity depends on how many times the charger will be able to charge a particular mobile gadget.
