Is that impossible? I want a gadget that charges fast and battery life is slow to empty. It’s good idea for emergency, long trip, playing chargeable toys, playing games, and more! Laptops is better. For cellphone with high pixels in front and back cameras and auto-focus, it’s good for reporting, photographing, etc. For everything! So, if someone invented that, the commercial will show up and my dream comes true! And, good-night and happy new year!
