The problem is with the powerful lithium ion battery. Theaverage scooter takes two hours for a scooter to charge, and a fullycharged scooter is able to travel up to 10 miles. According the US ConsumerProduct and Safety Commission, there have been at least 10 reports of fires causedby the scooters,although executives from companies selling the most expensive versions of thescooters argue that it's the cheap knock-offs that pose the real danger. Infact, Swagway scooters were just banned by Amazon after criticism involving the company's safety standards.
