Key Features to Look For:

1. Voltage and Current Rating:

   • Ensure it provides a stable 20V output.
   • Current capacity of at least 5A.

2. Adjustability:

   • Some power supplies allow fine-tuning of voltage and current, which can be helpful for testing or if your device operates within a range.

3. Input Voltage:

   • Check if it supports your region’s AC voltage (e.g., 110-120V for North America or 220-240V for Europe/Asia).

4. Safety Features:

   • Overcurrent, overvoltage, and thermal protection.
   • Short circuit protection.

5. Efficiency:

   • Look for high efficiency (80% or above) to reduce power loss and heating.

6. Form Factor:

   • Bench power supply for labs/testing environments.
   • Compact, wall-mount, or open-frame designs for permanent setups.

7. Connectors:

   • Verify compatibility with your device's power input (e.g., barrel connector, terminal blocks, or custom).
