This feature request is not for 450 but something to consider for next product other than the long requested Center stand, better mirror, better seat and better tyres etc.
If the charger can be integrated into the vehicle itself it would make things hassle free as one would not need to worry about DOT installation or carrying portable charger separately and not worry about theft or protection from rain if these are integrated. All that would be needed will be a wire with 5A plug so that it can be used almost anywhere. Placement wise it can be probably integrated right under the seat where there is colored metal bar (just a suggestion) but engineers at Ather would definitely be able to find the best area for placement. The existing charging socket can still remain to charge at grids.
