A university student came up with a new business idea during a night out and in six weeks has made more than $100,000 (£55,000).
Bailey Page, from Queensland, Australia, invented a new wireless phone charger after his mobile ran out of battery while he was ordering an Uber home from a nightclub.
The 22-year-old looked online for a cable-free charger that could fit in his pocket the next day but couldn't find one.
He then put his savings into developing the Zip Zap charger during his final year of study.
It clips onto the device and charges it in two hours.
Bailey sold out his initial stock of 200 within a fortnight in 2021 then sold another 1,500 across his homeland the next month.
Within six weeks he'd hit his goal of selling 2,000 chargers in a year.
He told local news outlet the Courier Mail about coming up with the idea: "My third year essentially, I just had to focus on getting uni complete while I did my studies.
"It was just a lot of late nights and weekend work to really cover up on what I couldn't do through the week when I was at uni. I thought to myself, you know what, if I failed, I at least had a go."
Bailey added: "I always encourage young people just to have a go. You have to put a plan on paper. It's always good to get outside eyes looking in and giving you feedback. You can never fail with starting and the biggest hurdle is actually just starting."
He has now sold 6,500 chargers to date.
