Understanding the Basics of a 50W mA Outdoor Power Supply

If you're planning to power outdoor devices like security cameras, LED lights, or IoT sensors, a 50W mA outdoor power supply is a popular choice. But how long can it actually last? Let's break it down.

Key Factors That Determine Runtime

• Battery Capacity: Measured in milliampere-hours (mAh), this defines total energy storage.
• Power Consumption: The device's wattage (e.g., 10W vs. 30W) directly impacts runtime.
• Environmental Conditions: Extreme temperatures reduce efficiency.
• Energy Loss: Cables, connectors, and inverters can drain power.

Calculating Runtime: A Simple Formula

To estimate how long your 50W power supply will last, use this formula:

Runtime (hours) = (Battery Capacity × Voltage) ÷ Device Wattage

Example Calculation

Assume you have a 50W power supply with a 12V, 20Ah battery:

• Total energy = 12V × 20Ah = 240Wh
• Runtime = 240Wh ÷ 50W = 4.8 hours

Real-World Applications and Case Studies

Here's how a 50W outdoor power supply performs in common scenarios:

1. Outdoor Security Cameras

Most cameras consume 5–10W. With a 240Wh battery:

• Low Power Mode (5W): 48 hours
• High Power Mode (10W): 24 hours

2. Solar-Powered LED Lights

LEDs typically use 5–15W. Pairing the power supply with solar panels can extend runtime indefinitely during sunny days.

3. Agricultural Sensors

Low-power IoT devices (2–3W) can run for 80–120 hours on a single charge.
