Manufacturers often quote impossibly optimistic battery life for their products assuming that users don't want Wi-Fi or any form of connectivity or use their screens at their lowest brightness settings when in fact it is pretty much the opposite.

The main reason for such a product would be to offer a significantly higher battery life without adding any weight to the laptop itself.

Instead, the additional components would be combined with the existing power supply units and be a better option than buying higher capacity batteries.

These cannot be charged independently from the laptop and you still need to power off the computer to swap it.

To some extent, products like PowerTravellers' Power Gorilla, New Trent's TY1800 or Energizer's Portable emergency battery are laptop chargers with built-in power pack (or vice versa), offering up to 70Whr in a 500g enclosure.
