This solar-charging iPhone X case might take a while to pay for itself

A new iPhone X case from Caviar that’s able to turn the sun’s rays into phone battery has just been released, but you’re going to have to catch quite a lot of sun if you want to generate enough free electricity for the case to pay for itself.

Specifically, you’ll need to generate close to $3600-worth of power to justify the cost of the ‘Tesla’ case, which comes complete with a 64GB iPhone X for $4600.

Let’s do the maths on how much electricity the case would have to generate before it pays for itself.

$3600 translates to roughly £2670. The Energy Saving Trust calculates that the average cost of electricity in the UK is 14.37p per kWh, so the case would have to generate 18,580 kWh to become a net game.

Without accurate numbers from manufacturer Caviar, it’s tough to know exactly how quickly this could happen, but it’s probably not a stretch to say you’re unlikely to hit that point anytime soon. (Insert joke about the British summer).

But then again, who can put a price on doing your bit for the environment?

So it’s not the safest financial decision, but the 24K gold accenting will at least add a touch of class to your £1000 device. It’ll need to as well, since the case will add a fair bit of bulk to your handset.
