Moore’s Law, smaller cheaper faster.
The question is exactly what when.
The video stated the obvious, what we know in general, better is coming sometime, what it didn’t tell us when is a smaller 60W, 85W, 100W charging coming.
Phones and laptops have different issues.
Phone batteries are so small, that a Powercore which can keep it charged twice over is around the $20 level and about the same size as the phone, so you don’t particularly need a dinky phone charger as you just carry your Powercore and the charger which never leaves home doesn’t need to be small.
Laptop batteries are so large, that a Powercore is very bulky to give 1-2 recharges, so you must carry a charger, these are coming down in cost for 60W but not yet particularly in size. Add a dongle hub for peripherals and you easily get to a need for a smaller 85W-100W. When exactly.
The 18W Nano charger can’t really get any smaller in any usefully meaningful way, but 60W-100W have a long way to improve and will benefit us.
