How to choose an electric wheelchair?
frame
At present, the frame of electric wheelchairs is mainly made of aluminum alloy and carbon steel. Many brands are also trying to use lighter magnesium alloy materials, and there are also carbon fiber materials that are very popular in medical devices in the past two years.

Friends around me will struggle when buying electric wheelchairs, so come and ask me.
: “Electric wheelchair, aluminum alloy or carbon steel, which one is better?”
As soon as he heard it, he knew that what he wanted to ask was not which one was better, but which one was the most suitable for him to start buying. Carbon steel, as we all know, or iron in other words, is heavy and not that strong. Don’t think about it, aluminum alloy is definitely better.

What are the benefits of a carbon steel frame? Iron! It’s cheaper! Aluminum alloys are lighter and more expensive.
The same applies to magnesium alloy and carbon fiber.
In terms of weight, carbon steel > aluminum alloy > magnesium alloy > carbon fiber.
In terms of quality and price, they are sorted in reverse.
Battery
There are two types of batteries in electric wheelchairs: lithium batteries and lead-acid batteries.
Lithium batteries last longer, are lighter and more expensive than lead-acid batteries.
Lead-acid batteries are the batteries commonly used in battery cars. It takes a long time to charge and is mainly too heavy. Therefore, electric wheelchairs are used as a scooter for the elderly. I do not recommend that you choose lead-acid batteries in order to save hundreds of dollars.
In addition, electric wheelchairs can be used on high-speed rail, subway, and bus.
However, there are special rules for getting on the plane.
Therefore, electric wheelchairs generally have two 6.6 A or one 12 A batteries.
If the elderly in the family need to fly, be sure to pay attention to the capacity of the battery when purchasing an electric wheelchair, otherwise it cannot be checked.
