I’m happy with the ownership of my vehicle with ather 450. I would like to suggest you to give built-in Power Bank which would internally get powered when charging the vehicle and could be used for the mobile charging purpose which is fixed. inside the vehicle and nonremovable which would make more convenience for the rider to keep his mobile phone charge while his driving inside the the Dicky The vehicle should charge the power bank which is built in when it charges the vehicle. charging should disconnect when the vehicle is not charging So that the power which is there in the power bank is only used for mobile charging. Lithium ion battery is not used for mobile charging
