What this adapter powers

The Graviton 20V 14A 280W AC adapter replaces HP chargers carrying part numbers TPN-CA26, M94073-002, M95376-001 and A280A011P. It delivers 20 volts at 14 amps for a total of 280 watts through a 4.5 by 3.0 millimetre barrel plug with a centre pin.

Input range and connector limits

The unit accepts 100 to 240 volts at 50 to 60 hertz, so it works on mains supplies worldwide when paired with the correct cord. Output is fixed at 20 volts and 14 amps; devices that require a different voltage, a higher current or a proprietary communication handshake will not charge from this adapter.

Installation and common issues

The package includes one adapter and one power cord with a choice of EU, US, UK or AU plug types. Installation is a simple cord swap and barrel insertion. Problems usually arise when the laptop expects a different pin diameter, a different centre-pin signal or a higher wattage than 280 watts.
