Wefomey Universal Adjustable 3–24V DC Power Supply 3A (72W) with LCD and Multiple Tips

Wefomey Universal Power Supply is a compact adjustable AC→DC adapter that delivers 3V–24V up to 3A (72W) with multiple connector tips for powering a wide range of small electronics.

This versatile adapter replaces stacks of single-voltage bricks by letting you set the exact DC output using a clear LCD readout. Designed for hobbyists, home electronics, security cameras and small appliances, the unit comes with a full set of interchangeable tips, protection features, and helpful accessories like polarity-reverse and splitter cables so you can power several devices from one reliable source.

How do I set the right voltage for my device?

Use the built-in controls and LCD screen to choose any output between 3V and 24V. The display shows the real-time voltage so you can confirm the setting before connecting your device. Voltage tolerance is within ±5% of the chosen value, which is typical for regulated adapters.

• Adjustable range: 3.0V to 24.0V in common steps (3V, 4V, 4.5V, 5V, 6V, 9V, 12V, 19V, 24V, etc.)
• Real-time LCD confirms output voltage while powering devices
• Expect small variation (example: 12V ≈ 11.4–12.6V) — normal for regulated supplies

Which connectors and accessories are included?

The kit ships with a broad selection of DC tips plus modern ports so you can match most consumer electronics without buying extra adapters. Also included are practical cables for splitting power, reversing polarity and connecting to bare wires for DIY projects.

• Multiple DC tips: 5.5×2.1mm, 5.5×3.0mm, 5.0×2.5mm, 6.3×3.0mm, 3.5×1.35mm, 3.0×1.1mm, and others
• Micro-USB and USB-C tips for contemporary devices
• Polarity reverse cable and alligator-clip adapter for breadboards and repairs
• DC 1→4 splitter cable for powering multiple devices from one adapter

Is it safe and reliable for continuous use?

Wefomey built the adapter with multiple safety layers and international certifications so it’s suited for indoor electronics and moderate continuous loads. Over-current, over-voltage, thermal and short-circuit protections reduce risk of damage to connected devices, and the 6 ft power cord gives flexibility in placement.

• Protections: over-current, over-voltage, over-temperature, short-circuit, anti-interference
• Certifications include FCC, UKCA, CE, and ROHS for safer operation
• Low noise operation and stable output when operated within recommended limits

How do I avoid overloading or damaging my devices?

Choose the correct voltage setting and ensure the total current draw does not exceed 3A. For split outputs, keep each branch under the advised per-connector limit and prefer using no more than 80% of the adapter’s total rated load for longer life.

• Max output: 3A (72W). Recommended sustained use below 80% of max load
• If using the 4-way splitter, total current must not exceed 3A; individual ports ideally ≤0.75A each
• Confirm connector size and polarity before plugging in to prevent damage

Who this is for: The Wefomey Universal Power Supply is aimed at electronics enthusiasts, DIYers, security camera installers, and anyone who needs a flexible single adapter to run multiple small DC devices. It’s a practical choice if you want one regulated supply for LED strips, routers, TV boxes, USB hubs, 3D printer peripherals and many other 3–24V gadgets without buying different chargers for each item.
