36W US Plug 12V 3A AC-DC Power Adapter Supply

Product Description

The 36W US Plug 12V 3A AC DC Power Adapter Supply is a compact, versatile power solution designed for North American users seeking a reliable 12V DC power source. Featuring a NEMA 1-15 standard US plug, it connects directly to outlets in the US, Canada, and Mexico, delivering a stable 36W output (12V, 3A) for a wide range of low to medium-power devices. The adapter balances portability with performance, making it suitable for home, travel, and light commercial use.

The adapter’s sleek design (88mm x 48mm x 72mm) and lightweight construction (150g) make it easy to carry in a bag or pocket. The outer shell is made of impact-resistant, flame-retardant ABS plastic, meeting UL94-V0 safety standards to prevent fire hazards. Internally, a high-frequency switching circuit ensures precise voltage regulation, minimizing ripple noise and protecting devices from harmful fluctuations. A 1.8-meter power cord with a molded strain relief provides durability and flexibility for positioning devices away from outlets.

Features

Universal Voltage Input: Accepts 100–240V AC, 50/60Hz, making it suitable for international travel when paired with a plug adapter (not included for US plug). This feature eliminates the need for multiple adapters, simplifying life for frequent travelers.

Triple-Layer Safety Protection: Equipped with over-voltage, over-current, and short-circuit protection, automatically cutting power to prevent damage during electrical faults. The adapter also features thermal shutdown protection, activating when internal temperatures exceed 70°C to ensure safe operation.

High Efficiency & Low Noise: Achieves up to 86% energy efficiency, reducing heat generation and standby power consumption (<0.5W). The passive cooling design operates silently, making it ideal for noise-sensitive environments like bedrooms or offices.

Wide Device Compatibility: Works with any 12V DC device requiring up to 3A, including Wi-Fi routers, IP cameras, LED light strips, small monitors, and portable audio systems. The standard 5.5mm x 2.1mm DC connector fits most industry-standard ports, though non-standard connectors may require an adapter (sold separately).

Application

Home Electronics: Powers essential home devices such as smart speakers (e.g., Amazon Echo, Google Nest), security cameras, and streaming media players, ensuring reliable connectivity and operation. Ideal for DIY projects like custom LED lighting setups or small-scale robotics.

Travel & Mobility: Perfect for charging tablets, e-readers, and portable game consoles while traveling. Its compact size fits into any travel kit, and the universal input means it works in hotels worldwide with a simple plug adapter.

Small Business & Office Use: Supports low-power office equipment like IP phones, network switches, and small printers. The adapter’s reliability makes it a cost-effective choice for maintaining uninterrupted operations in small workspaces.

FAQ

Q: Can I use this adapter with a 220V outlet in Europe?

A: Yes, the adapter supports 100–240V input. However, a European plug adapter (to convert the US plug to local sockets) is required. Do not use it without a compatible adapter, as the plug shape differs.

Q: What happens if my device requires more than 3A?

A: The adapter will not exceed its maximum 3A output. If your device needs more current, it may not operate correctly or could trigger the over-current protection, shutting down the adapter. Always check your device’s power requirements first.

Q: Is the DC connector polarity tip-positive or tip-negative?

A: The connector is tip-positive (center pin positive, outer sleeve negative), which is standard for most 12V devices. Verify your device’s polarity to avoid damage; reverse polarity may require a converter cable.

Q: How do I clean the adapter?

A: Unplug it from the outlet and wipe the casing with a dry, soft cloth. Do not use liquids or abrasive materials, as they may damage the surface or internal components.
