General Requirements: < Br /> < Br /> Input Voltage: AC 100-240V 50/60Hz (suitable for worldwide use)< Br /> Output Rating: At least 20W (to enable fast charging for iPhones and iPads)< Br /> Plug Type: EU plug< Br /> Connector: Type-C to Lightin, Type C to Type C< Br /> Safety Certifications: CE marking (for compliance with European safety standards), relevant safety certifications for your target market< Br /> For Minimal Heat Generation: < Br /> < Br /> Look for chargers with Gallium Nitride (GaN) technology. These are known to generate less heat than traditional silicon-based chargers. < Br /> For Fast Charging: < Br /> < Br /> USB Power Delivery (USB PD) is a fast charging protocol supported by most iPhones and iPads. Make sure the charger supports USB PD. < Br /> The output rating of the charger should be at least 20W for fast charging iPhones and iPads. Higher wattage ratings will also work but won't necessarily charge your devices any faster. < Br /> Additional Considerations: < Br /> < Br /> Material: Look for chargers made with fire-resistant materials. < Br /> Brand: While not always the case, well-known brands may offer better quality and safety features.
