Solar Chargers worth spending money?I was checking the powerbanks while I came across the solar chargers. However I am unsure if they are worth using. I mean in case of solar chargers they need to be around very clear source for light to charge up. It'd be good for the train or bus journey. But I can't think of using them for the regular usage. Also summer may not be the biggest most of the time. I wonder how the solar charger fairs in case of low light months such as rainy season and winter.
There are some youtube videos in favor but still not convinced if they are still viable in terms of investment. I think it'd take time for those chargers to improve and be usable to reach regular level of use.
Have you used solar chargers for say mobile or powerbank? Are they worth buying?
