It is a special item. It requires certain knowledge to buy an electric wheelchair, but the fact is that consumers are not aware of enough and afraid of losing money, so it is easy to choose a cheaper one. Sellers are not professional enough and rely on prices and sales to fool consumers; in order to cater to consumers’ pursuit of low prices and frivolity, manufacturers either cut corners or burned advertisements, no one said clearly. The whole format is messy! In addition, due to the low turnover rate of wheelchairs, the pricing is much higher than that of motorcycles, and replacement is slow. Looking at foreign countries, the price is so expensive that you can buy a car, which may not be suitable for national conditions. Most of them are behemoths weighing nearly 200 kilograms, and there are few portable electric wheelchairs.
If you buy an electric wheelchair for temporary travel, the user has the ability to walk independently, or someone is with you when traveling, then the price must be considered, and whoever buys it is cheap, the quality of domestic wheelchairs is similar, so lucky!
Motor: Domestic motor, with loud running sound, long time of use, obvious power drop, and easy to slip; currently Taiwan recommends imported motors, no matter how good they are, there are basically none in the market, or the price is too high. Motors are divided into brush motors and brushless motors. The advantage of the brushless motor is that it is quiet, but the brush is more durable than the brushless, the power is greater, and the maintenance cost is low. The former was broken and only a few dollars of brushes were replaced, while the latter was broken and completely replaced, and it is easily affected by the electromagnetic environment. Turbine worm is better than gear motor, with smooth transmission, low noise and long service life. In the case of climbing or complicated road conditions, it is recommended to equip with a motor of 500w or more, so that the high-wattage capacity will be better.
Controller: domestic controller, response is too fast, low safety factor, easy to break; imported, represented by British PG, mostly used in mid-end wheelchairs, obviously better to use than domestic ones, smoother and smoother! There is a delayed response setting, which is very important for the elderly! Due to old age and slow response, delayed response greatly increases safety. At present, many manufacturers have the name pg, but in fact, some PG accessories are synthetic, and the weight is lighter than the original manufacturer. For unconscious users, it is recommended that the controller be installed and operated by someone behind.
Battery: Lithium battery has the advantage of light weight, can be customized with high mileage, and the price is higher; lead-acid battery is too heavy, but the safety factor and cruising range are high, the price is low, and the heavier the more durable. Now it is basically the domestically produced battery in the world, and the kilometers are all falsely reported, so you can directly get a 60-80% discount. Even if the imported batteries are marked, they are probably only imported chips. The batteries are still made in China. The price of 20Ah capacity is 1.5-2k; the original imported batteries are only used for wheelchairs, which are durable but expensive.
