Can You Use A Higher Wattage Laptop Charger. It doesnt matter even if u use a lower power brick your components need enough voltage and guess what 6545 is not gonna help you can probably even break your laptop it. Charge Up to 40 Laptops.
I contacted HP support chat twice and was told this adapter is compatible with the laptop. It will actually charge your battery faster. For instance using a 45.
However one should try to use the original.
While the voltage and polarity should match with the original charger the amperage and wattage should exceed the required value or match it. Set it to the performance profile. If the system can accept the higher wattage then you will find that the battery charges faster -- and some systems will accept higher wattage. This is because the Laptop is designed in such a way as there is the maximum power that can be drawn by the system.
