Fast wireless charging on the cheap
As it has been already pointed out, wireless charging has a number of drawbacks, e.g. it's a misnomer, not being wireless at all, as it still needs a wire from the wall wart.
But what most people concentrated on the iPhone lost, is that "instant wireless" charging is already a reality.
It's simple as having a second charged battery, and even better it's mobile, you can take it with you.
The only things you need are:
- a phone with user changeable battery.
- a second battery.
- an external charger for the battery.
The battery and charger will set you back roughly $50, so it's cheap. It's not so elegant as a wireless charger, but it does not waste electricity and it's instant charging.
