Questions about this item

Does my laptop need a 7.4 mm barrel connector to use this adapter?

Yes, the tip measures 7.4 mm so the laptop must accept that size for a secure fit.

Can I keep using my existing HP charger rated below 280 W while this one is connected?

Only one power source should supply the laptop at a time; mixing a lower-wattage charger with this 280 W unit is not recommended.
