I found that smaller, lightweight models were easier to handle, especially when working in tight spaces. However, I also had to balance size with capacity to ensure I had enough power for my needs.

Durability and Weather Resistance

Since I often use my 12V power supply outdoors, durability became a priority. I looked for models that were rugged and weather-resistant. A good power supply should withstand the elements, including rain, dust, and extreme temperatures. This consideration has saved me from potential issues during outdoor projects.

Safety Features

Safety is always a top concern for me. I looked for features like over-voltage protection, short-circuit protection, and thermal shutdown. These features provide peace of mind, knowing that I am protected against potential hazards while using the power supply.

Ease of Use and Connectivity

I prefer power supplies that offer multiple output options. Having various ports allows me to connect different devices simultaneously. I also appreciate simple controls and clear indicators, which make it easy to monitor the power supply’s status.

Price and Warranty

Budget is always a consideration for me. I found that prices can vary widely based on features and quality. I aimed to find a balance between cost and functionality. Additionally, I always checked for warranties, as they indicate the manufacturer’s confidence in their product.
