Please kindly note that it's very slow for the solar charger to recharge itself via solar power and may take several days subject to intensity of sunlight and panel positioning, due to the limited surface of the solar panel. But much quicker via Electricity.
Charging your power bank using the solar panel is very slow due to small surface area of solar panel and may take several days with the right conditions. IT is important to note the factors that can affect the performance of the solar panel such as brightness of the sun, direct exposure to the sun and angle of contact, size or surface area of the solar panels, temperature, battery size and frequency of usage. The implication is that it can take several days to charge a solar power bank strictly using the solar panels. The larger the solar PV, the faster it can charge and the shorter the time taken. It is ideal in emergency situations as backup power source in the absence of regular electricity supply. For best results, the user should:
Solar: Find a safe and bright spot outside with strong direct sunlight
Solar: Position your solar power bank in a way that ensures the solar panel is facing up directly toward the sun
Solar: Ensure there is adequate ventilation to avoid overheat
Solar: Monitor the LED light bulbs that indicate the level of power stored in the power bank
Test of Quality and Originality
Beware of similar power banks claiming to offer 20k, 30k, 50k, 60k mAh, etc.
It is impossible to pack such capacity into this size. Below are some tips to bear in mind
Think! Your standard smart phone battery is typically 2500 mAh on average.
20,000 mAh is equivalent to 8 smart phone batteries.
However, weight isn't a guaranty of quality. Bags of sand and other rubbish have been found in some of them.
Top brands don’t offer these unusual and strange capacities for similar size of power banks. Think of the reason why.
Ask yourself, can 8 ,24, 40, etc batteries be of the same weight & fit into the power bank case?
Beware and do these basic checks before you buy. Buy quality.
