Tips for Choosing and Using AC Adapters
1. To find ac adapters for your laptop, you have to know what is the brand and model of your laptop first. For example, if you have a Dell Inspiron 1525 laptop, 'Dell' is the laptop brand and 'Inspiron 1525' is the model.
2. Some lower watts adapters can be replaced by higher watts adapters if they are the same in voltage and tip size. Such as Dell PA12(65W) can be replaced by Dell PA10(90W). Attention: NOT ALL adapters can be replaced by higher watts adapters. We strongly recommend you ask professionals for suggestions before doing so.
3. Using the laptop power adapter outdoors or in harsh environments should be avoided in case the power adapter is exposed to sunlight or becomes damp.

4. Unplug the power adapter when you do not use the laptop. Because, prolonged charging keeps the power adapter in work status, which will negatively affect the power adapter's ultimate lifespan.

5. Although the power adapter can work within the voltage from 100V to 240V, if the voltage is very unstable, it will also cause damage to the power adapter.
