I'm looking for a lightweight and affordable electric wheelchair that can provide easy mobility for users. It should be compact for storage and transportation, yet durable enough for daily use. Additionally, I'd like to know about the available features such as battery life, charging time, and weight capacity. If there are any options for customization or upgrades, please provide details as well. Looking forward to your response!
