    I have a Dell Inspiron n5110 and their power supply quality control must be horrible since I'm on my 3rd one and they all have made crackling sounds. The first 2 did it right away and this started a few weeks back and is getting worse. So I'm trying to find an alternative to just getting another one of them and looking online one of the 3rd party replacements had the same specs as a previous Dell laptop's charger I own. I tried it out and it charges but I want to make sure it's safe before making it my main charger. Also for the load the laptop drives one of those USB fan bases.

    The n5110 charger's output is: 19.5V 6.7A 65W

    The old laptop's output is: 19.5V 4.62A 90W

    The first one isn't 65W, it's 130W (19.5V*6.7A=130W) unless you read the amperage wrong. I wouldn't use a power adapter with less wattage than the original and most important of all the voltage has to be the same.

    Also, the USB cooler does not count. It is not connected as an additional load to your charger - it is part of the laptop. So if you had a scenario where your charger split into two and one went to the laptop and the other to a cooler, that would be an extra drain. In this case, you needn't take that into consideration while purchasing a charger. Just make sure you stick to the guidelines tijo outlined in his post above.
