Even indoor light will charge the internal batteries, but daylight is best.
And that battery pack holds 50 hours of charge anyway.
So, why arent all gadgets solar-powered?

“Consider solar panels on a house.
They have a massive surface area compared to your phone, and your home runs quite efficiently.
Your phone requires a huge power commitment that can’t currently be converted from solar energy.”

Size Matters
Headphones sip energy.
The same has been true for smaller deviceswatches, pocket calculatorsfor decades.
But when it comes to phones, things get tricky.

First, you need more power, and therefore more light, which translates to bigger solar panels.
On a phone, where would you put them?
Headphones natural habitat is the open air.
They sit on your head, always in the best spot for gathering photons.
And because theyre on your head, you never leave them in a dangerous environment.
“The simple answer is cost,“weed reviewerand solar panel installer Caleb Chen told Lifewire via email.
“It isn’t as simple as taking a solar panel and taping it onto an existing product.
The panels, themselves, and their wiring need to be integrated into the product body, itself.”
Urbanista’s headphones use a material called Powerfoyle, whichcan be screen-printed onto fabric.
That means overcast days or indoor lighting.
Its also less picky about the angle of the light falling on it.
Convenient, Not Green
The main point of solar gadgets is convenience.
But what a great boon it is.
Imagine never having to charge your headphones again.

So, should we expect solar charging for other gadgets?
It also costs more to make a self-charging gadget, all else being equal.
Planet-wise, it makes more sense to focus on renewable energy, in general.
That means that any electrical devices are, environmentally speaking, free to use.
There is, of course, an environmental cost to building out the infrastructure, but thats fixed.
In other words, solar headphones will make no difference to the climate crisis.
But that doesnt make them any less cool.
