Review on HP 230W Laptop Charger Power Adapter Cord for EliteBook 8460W 8540P 8560P 8570W 8740W 8760W 8770W, ProBook 6360B 6465B 6545B 6560B - 19.5V, Model: AT895AA 535592-001 609946-001 613159-001 693706-001 693714-001 by James Vilchez

The AC adapter works great, looks solid and is an original HP charger. For people not expecting it, that's huge. The weight is at least 2 or 3 pounds and the PSU is about 8 x 4 x 1.5 inches. There's also a very faint green light to indicate when the power supply is plugged into an always-on power supply, which I know can be annoying depending on where and how you're using it. But it works great, charges fast and feels very durable.
