Just returned from China/Hong Kong/Singapore. My TravelScoot now has 20,000 miles on it. I've learned that the new Lithium battery will last going through the Phoenix airport (a big airport), Singapore (another big airport) without a charge. However when you run it on carpet it runs down faster. I've seen the yellow on the meter.
The learning curve for my driver in Hong Kong was fast; he was assembling it very quickly. My scooter allowed me to get around the grocery stores I was looking at and that helped a lot. Everyone I met was impressed with it. It does have its limitations: it doesn't do big hills very well when it is running low on charge. Luckily people pushed me. I didn't take it on the Red Star Ferry this time...will next trip.
If I had a magic wand I'd install a charger input off of the handle so you could plug it in easily without removing the battery. Should be able to be done. I'd also install a 'plug' that could be used to power your cell phone or GPS unit. Maybe I'll do this myself when I get a chance and let you all see it.
Next month I'm doing another 20,000 miles so I'll keep you in the loop. By the way the captain on the plane from San Francisco yesterday told me he saw one of these units at the Seattle aiport; perhaps it was Hardy? ha ha
