Accessories are generally categorized into Protection (cases, screen protectors), Power (chargers, power banks), and Audio/Connectivity (TWS earbuds, adapters). For retail markets, aesthetic design and retail-ready packaging are vital. For corporate or promotional use, focus on custom branding (OEM/ODM) capabilities and cost-effective bulk pricing. High-demand features currently include MagSafe compatibility for iPhones and GaN (Gallium Nitride) technology for ultra-compact, high-wattage chargers.
