A charger the size of an AirPods case raised €591,000 on Kickstarter.
The goal was €20,000. It hit 2,900% funded.
Here's what Rolling Square actually did:
→ Took a 100W USB-C charger that powers a MacBook Pro
→ Made it 65% smaller than Apple's version
→ Weighed it at 100 grams
→ Made it fold flat
That's it. No new technology. GaN chips have existed for years. They just packaged them smaller.
This is their 10th Kickstarter. They've sold 2.2 million products worldwide.
The lesson isn't about chargers.
The best businesses don't invent new demand. They remove friction from products people already use.
