An AC-DC Adapter is a versatile device designed to convert alternating current (AC) from the power grid into direct current (DC) needed by most electronic devices. This conversion is essential because while our homes and offices are supplied with AC power, most electronics, such as laptops, smartphones, and other gadgets, operate on DC power.
Boasting four output specifications—9V 4A, 12V 3A, 18V 2A, and 24V 1.5A—with a stable total power of 36W, this adapter eliminates the need for multiple chargers for different devices. It effortlessly adapts to diverse voltage requirements, such as 12V 3A for routers and switches, or 24V 1.5A for small DC motors.
With a wide input voltage range of AC100-240V and compatibility with 50/60Hz frequencies, it meets the power grid standards of most countries and regions worldwide, enabling hassle-free use during business trips or cross-border applications without additional converters. Featuring an efficiency rating of ≥80%, it minimizes energy loss during conversion, reducing long-term electricity costs while aligning with energy-saving initiatives.
Equipped with four-layer protection—overvoltage protection, short-circuit protection, overload protection, and temperature protection—it ensures maximum safety for both devices and users. For instance, it automatically cuts off power in case of short circuits to prevent device damage, and activates temperature protection to avoid overheating during prolonged operation, significantly lowering safety risks.
Operating within a temperature range of -20℃ to +50℃ and a storage temperature range of -20℃ to +80℃, it performs reliably in 10%-90% RH humidity. Whether in the cold winters of northern regions or the humid rainy seasons of southern areas, it maintains stable performance, making it suitable for global deployment.
Certified by CE and ROHS, the adapter adheres to EU safety, health, and environmental standards, ensuring smooth market access in the EU. These certifications also validate its compliance with eco-friendly material requirements and electrical safety norms, guaranteeing low levels of harmful substances.
Ideal for corporate clients, it offers OEM customization options tailored to specific needs, such as appearance design, interface specifications, and brand logos. This makes it a perfect fit for batch production in industries like 3C and smart home.

Suitable for portable media players, small game consoles, and legacy digital devices—e.g., powering 9V portable voice recorders or 18V handheld digital gadgets.
Compatible with backup power for smart door locks, small security cameras, and drive motors for smart curtains, with voltage selection based on device requirements.
Beyond routers and switches, it can power small LED strips (e.g., 24V strips), mini water pumps, small relay modules, and low-power industrial control modules.
It offers four stable output specifications to meet diverse device needs: 9V 4A, 12V 3A, 18V 2A, and 24V 1.5A, with a consistent total output power of 36W.
To ensure maximum safety for both devices and users, it is equipped with four comprehensive protection functions: overvoltage protection, short-circuit protection, overload protection, and temperature protection. These features automatically trigger to prevent damage in abnormal operating conditions.
Yes, the adapter has obtained CE and ROHS certifications, meeting strict EU safety, health, and environmental requirements. It can be legally sold and used in the EU market and other regions that recognize these certifications.
Absolutely. We support OEM customization to cater to your specific business needs, including adjustments to appearance design, interface types, brand logos, and even output parameters (within technical feasibility). Our 15+ years of manufacturing experience ensures high-quality customization and on-time delivery.
It operates reliably within a temperature range of -20℃ to +50℃ and can be stored in environments ranging from -20℃ to +80℃. It also performs well in humidity levels of 10%-90% RH, adapting to various climatic conditions.
This versatile adapter is widely applicable to 3C products (e.g., portable media players, small game consoles), smart home devices (e.g., smart door locks, security cameras, smart curtain motors), routers, switches, small DC motors, mini water pumps, LED strips, and low-power industrial control modules.
While the adapter itself is not fully waterproof, its wide operating temperature and humidity range allow it to be used in covered outdoor environments (e.g., under eaves or in waterproof device enclosures). For fully outdoor applications, we recommend confirming the device’s waterproof rating and using additional protective measures.
