Why has no one comes up with this idea before now? Brando is selling a solar power Bluetooth headset which claims to offer unlimited standby time, but which can also be charged via traditional methods. Love the idea and it also looks quite smart.
“Tiny size Bluetooth Headset with 2 Charging Ways: Solar Power or USB Charging via PC/Mac, notebook, AC power etc. The most convenient way to charge up the Headset using the unlimited Solar energy! Infinite Standby time under Sunlight! It supports Mutiple Pairing that Each Headset connects up to 2 bluetooth mobiles/devices at a time!”
Apologies for the usual sarcasm, but I suspect probably because someone held a patent on something.
I looked for this a while back but found nothing, and I’m far too dumb to be the first to think of anything
