For my HP laptop, can I use a HP 65W Smart AC Adapter instead of a HP 45W Smart AC Adapter

[Geoff_L]

I have an HP 65W Smart AC Adapter H6Y89AA. Can I use it with my HP 15s-eq1013ni Ryzen 5 Laptop (SKU: 2C7G7EA), which normally uses the HP 45W Smart AC Adapter H6Y88AA?

Hi@Geoff_L,

Welcome to the HP Support Community! I'd like to help!

I see you want to know if can use the 65W adapter instead of a 45W adapter on the HP Laptop PC.

I have a few recommendations 

• As long as it is the same voltage and connector type you can use a higher watt adapter. It will charge the battery a bit faster but other than and the size of the brick you will see no difference. The laptop will only draw the current it needs while running.
• On the condition of same voltage, laptops and other devices will never overpowered. 
• Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won't damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.

Hope this helps! Keep me posted.

Thank you - your answer confirmed my understanding regarding the use of different adapters/chargers.

I assume that all HP adapters/chargers are designed with the same polarity (+ve). Out of interest, do you know if any of the main laptop/notebook manufacturers employ negative polarities for their adapters/chargers?

Hi@Geoff_L,

Thank you for responding, I appreciate your time and effort.

HP Laptop chargers are usually center positive, outside negative.

Most manufacturers use the center pin for positive voltage and the outer shield for negative voltage. Some manufacturers use the opposite convention. This manufacturing standard uses the center pin for the negative voltage. Connecting an adapter with the wrong polarity could cause damage to your electronic device.

Please feel free to contact us here anytime you need any further assistance.

Have a great day!
