This is a strange invention that demonstrates outside-of-the-box thinking. A startup called Swippitt has developed this Instant Power System, a way to fully charge your smartphone in just two seconds. The system requires you sheathe your phone in their Swippitt Link, a phone case with a built-in battery. To recharge, you place your phone into the slot of their Swippitt Hub, which looks like the offspring of an Atari 2600 and a toaster. After two seconds, you pull it out, and it's fully charged.What's happening inside the Hub is that it's swapping the case's battery:The Hub can store and charge up to five extra batteries. I would think that this system would be aimed at businesses with employees that rely heavily on smartphones to do their work, but this appears aimed at the consumer sector. It's also only compatible with iPhone models 14, 15 and 16. Whether people will pony up $120 per phone case and $450 for the Hub (plus whatever the extra batteries cost, they don't say) remains to be seen.The system is expected to launch in June, with Android compatibility to be added later.
