Do you want a USB charging port on your scooter? Do you have an under-seat battery, or a Battery Tender pig-tail tucked away in a storage area?
Deltran Battery Tender folks have a cheap and very easy solution to scoots without USB ports installed.
Attach this to your battery tending pig-tail and you will have a USB charging port!
Check out the specifics on their web site.
They also sell a Digital Battery Voltage Indicator with LCD display which can be plugged into the scooter's battery tender pig-tail.
Display range is 3 to 16 volts.....with green, yellow and red lights.
Piaggio sells a USB wiring accessory kit for $70 for my new Liberty - but I'd rather not drill holes & mess with my scoot's wiring. This Deltran solution is for me - cheaper, less complicated and foolproof.
