If the standard iPhone 10 is just not enough for you, luxury gadgets manufacturer Caviar has released a modified version, complete with a solar panel to charge the battery. It is not so sunny on the bank balance though – the phone starts at $4,400. The solar panel on the Tesla iPhone X charges the battery in around 30 hours. And yes, it was named as a tribute to Elon Musk’s electric car company. However, the phone apparently got rather hot when it was charged the normal way. It may be out of budget for most of us, but the Tesla iPhone X certainly catches the eye. MacRumours got their hands on one.
