Compatible HP Models

This 19V 4.74A AC adapter replaces the original charger for HP G70, G71, G72, 2170p, 2540p, 2560p, 2570p, 2740p, 2760p, 6930p, 8440p, 8440w, 8460p and 9470m laptops. It delivers 100 percent OEM compatible power for daily office work and mobile use. The unit ships new with a 10 ft power cord included.

Sustained Load Behaviour

Over current protection, over voltage protection, short circuit protection and total power protection engage automatically during continuous operation. The smart chip manages overheating while isolation materials reduce interference. World wide input voltage of 100-240VAC at 50 or 60Hz maintains stable output across varying mains conditions.

Installation And Common Issues

Connection is straightforward: plug the mains lead into a wall socket and the barrel tip into the laptop. The 10 ft cord reaches distant outlets without strain. Buyers who need a higher wattage unit for larger workstations or a USB-C power delivery adapter for modern ultrabooks will find this model unsuitable.

Questions about this item

Does the 19V 4.74A adapter run hot or draw extra power when left plugged in all day?

The unit includes over-current, over-voltage and short-circuit protection plus a smart chip for overheating protection, so it regulates temperature and power draw during continuous use.

What must I already own to use this 10 ft mains cable with my HP laptop?

You need a wall socket that accepts the supplied AC plug and one of the listed HP models such as the G70, 2540p or 8440w; the adapter connects directly to the laptop's DC jack.

Will this 100-240VAC charger work reliably with an older HP 6930p that still uses the original barrel connector?

Yes, the adapter is 100% compatible with the 6930p and other listed legacy models, matching the original voltage and connector specifications.
