My son asked me to install a USB outlet in his scoot.
After some research I settled on these.
Twin USB rated at 2.1A on both plugs.
Mostly his trips are quite short (HKG) so the extra rating
will be good for both the phone and extra battery.
Relay fuse replaced with 5A (Orig 30A although 3A would probably do)
Will wire directly to battery and trigger relay via low beam.
Need to replace the rear brake cable so ideal time to add the wiring when the panels come off.
