Please can you create a product/power bank that can charge a laptop and other devices without being plugged into the wall.
You can make it like a powerbrick that has a battery in it.
So it can be plugged into a wall and used without it as well.
This way everybody will have to carry just 1 charger that can charge everything, with AND without being plugged into the wall.
It is the ultimate charger.
The One Charger to Rule Them All.
Hope to see this product soon, I am fed up of carrying different power bricks for all of my devices.
