I want to charge a solar light with my indoor lights, which are quite string. Will that work?
No, it will not work. The energy from indoor lights is a tiny fraction of solar energy, so you will not get any useful charging happening.
You will probably get about 5-10% of the sun's charge, so it will only last for a few minutes.
The answer is no.
I use Indoor solar lights which require energy from sunlight. They are energy-efficient, while some come with options of charging with the aid of a USB cable, indoor solar lights are also capable of charging efficiently under the sun’s direct heat.
So long as the battery is fully charged, you can rest assured that you can rely on long-lasting lighting.
Solar lights will work more reliably and efficiently if exposed under the sun’s direct heat. If fully-charged, they can last long and provide sufficient lighting and brightness that you require.
