Another very similar one but higher price.

Ez lite chair

That does look interesting. I will have dh critique it. He can always see the good features as well as the drawbacks to these kinds of things. I have a Hoveround that dh bought used for me really cheap a few years ago. He calls it overpriced, poor quality and poorly designed. It needed a lot of fixing and t l c, which he gave it just for me to play around with it. It is more compact than my 3 wheel scooter, but I am not comfortable with using it in public places. Hard to transition from the handlebar steering to the joystick type of steering, and the lift in my van for the scooter would not work for it.

It weighs 50 lbs. Is that considered lightweight for this sort of chair? The guy lifts it out of the vehicle with ease, but I'm sure my experience would be quite different. :-)

I wonder if Medicare would pay for this like it does for a Scooter...

Be very cautious with some of the lighter weight chairs. Make sure you have local service and repair. Several of them require shipping at your cost back to the factory. They had a whole collection of them at the nursing facility ,where my son was a resident, all because of the service issues. Also besides weight, the clumsiness for lack of a better term, can keep you from being handled. A larger person with more arm length has better control at lifting.

Its tough to critique the chair without actually handling it. My impressions from viewing the video:

1. It is light for a power chair and seems built strong enough for occasional use. It may not be adequate for someone weighing 200 lb or more.
   
2. It is foldable and stows in a reasonable space - a plus.
   
3. It may not have enough stored energy in the batteries for extended use. Nothing was said about how much energy it stores, or better still, how much output energy is available.
   
4. Motor power and efficiency was not mentioned.
   
5. Operating speed and speed range not mentioned. From what I saw, it was mostly operated at one speed.
   
   6. Is seat width? A person with a wide bottom might not fit in it.
   
6. Can it be manually operated like a standard chair? Important if the battery pack runs down and you are not at your vehicle or station.
   
7. What's the recharge time?
   
8. Can is be recharged from a vehicle's electric system while the vehicle is underway? Important for travelers.
   
   10. Does it use standard cells? In other words, can a user replace cells. Important for travelers.
   
9. Someone mentioned small front wheels. I, too, think the front wheels are too small and the footprint may be too small for operating on soft surfaces. The wheels will sink in. The small wheels will stub on small chips and depressions.
   
10. Seat comfort: Can a person endure sitting in the chair for several hours?
    
11. Accessories: Are trays available that can be used for eating, writing, or operating electronic gear such as tablets and computers?
    

Some of that information is available on the site like the weight limit, it's I believe 265 for the regular and over 300 for the HD version which also has a bigger seat size. The batteries are shown, they are long and slide in on each side, are lithium ion, it said time of about 15 hours I believe and speed is also given but I don't remember I know it was less than mine but mine goes very fast..

The batteries are specifically made to fit so having back up would be a good idea. They would be same as any other lithium ion battery. And I am sure has a charger specific for it which comes with it.

I did see a list of available accessories.

There's not any electric wheelchair that I know of that can be manually used as a regular chair but they have a free wheeling lever that allows them to be pushed same with most scooters, mine does.

It for me would be fine for an additional method of mobility aid, I don't think anyone who is full time and unable to walk at all would be a good fit for this type of light weight. The second link model does have bigger better front tires but overall I think the first one is better made. You might be able to get different front wheels for them no idea.

I think this is an area of mobility options that is growing rapidly and the technology is improving with it all very good things because there's a lot of boomers that are needing assistance!

oh wow here is another one very very similar it comes with a lot of free stuff including a free car charger so you can charge it from the cigarette lighter. AND it comes in lots of colors.

Thanks to NTT for this link.

Foldable and yet another

Now for those wanting a more standard type wheel chair that still has the hand rails and wheels this one could be a good option for a powered one. However it weighs in at 90lbs. But it has very nice tires and rails.
