The adjustment range of the input voltage of the power adapter is the maximum change value of the allowable input mains voltage, generally 90~264V AC, corresponding to 90V~132V AC under 110V voltage, and 176V~264V AC under 220V voltage..
1. It must be recognized that the power adapter is a high-frequency, long-term electronic product, such as a mobile phone charger, which is basically used every day.
2. The power adapter is a product that requires safety certification, and there may be a short circuit or burning during use.
In short, users must consider quality issues when purchasing power adapters, and the quality is reliable before they can be used safely. 24V power adapter
The materials used for the internal electronic components of the power adapter are roughly divided into three types, the lowest level is the old material or the fake material; the middle level is the inferior material; the highest level is the good material. Generally, shanzhai will use old materials and fake materials to make up the number, non-brand manufacturers will use better inferior materials, and only first-tier brands will use the best quality real materials and good materials. Therefore, the two 36W power adapters of the same level, the products with an average price of 30 yuan are better than the cheap ones with only 15 yuan.
