On the other hand, most quality solar power banks are built with smart protective technology that prevents overcharging. Charging your solar power bank involves two main methods: solar and electrical charging. Here’s the deal: solar charging is simple, eco-friendly, and entirely free. Simply place your solar power bank under direct sunlight.
The charging capacity of a solar power bank refers to the amount of energy it can store and the amount of devices it can charge. Solar power banks come in different capacities, ranging from 5,000mAh to 20,000mAh or more. The higher the capacity, the more devices you can charge and the longer the power bank will last.
While a solar power bank is designed to harness sunlight, you can still charge it electrically using a wall charger. Just connect your bank with a suitable wall charger using a USB cable, then plug the charger into an outlet. Wall charging is just another fancy term for charging your power bank using a wall adapter.
How long a solar power bank needs to charge up depends on the size of the solar panel and the amount of sunlight. As sunlight is not reliably available and the solar panel surface of most power banks is relatively small, it can even take several days before a usable charging level is reached.
So, now your mobile device and power bank have no charge! To avoid this situation from recurring again in the future, you have the option of using a solar panel in conjunction with the power bank to effectively create your own mobile solar power system.
Most solar power banks have small LED indicators that notify the user of the battery’s status. Usually, continuous light signals a full charge, while intermittent blinks signify an ongoing charge. Different manufacturers may have different ways of displaying charge level indicators.
