When evaluating Foshan wheelchairs, prioritize frame material (lightweight aluminum alloy for portability or carbon steel for heavy-duty durability). Ensure the load capacity meets your target market needs, typically ranging from 100kg to 150kg. For electric models, verify battery type (Lithium-ion is preferred for international shipping and longevity) and motor power (typically 250W dual motors). Additionally, check for breathable, flame-retardant upholstery and puncture-proof tires (solid PU or honeycomb) to reduce maintenance costs.
