It is inevitable that power adapter ought to be so big size for such high power consuming notebook. Mind you the adapter is churning out 240W of power, or 4 times of your regular credit card sized notebook 60W adapter, all under noiseless, passive heat conduction. It ought to have massive heatsink inside to do all that. Whereas SFF desktop PSU of such power capacity usually generate turbojet fan noise from its tiny internal fan to cool them adequately.
Then again, the chunk of 240W adapter may look big in size but it is actually rather thin as per image below:
And it is definitely not as big as 4x 60W adapter placed side by side together.
And it is also rated with Efficiency V, which is already the highest energy star rating possible. Quite a big feat for such high capacity PSU, as it is usually tougher for PSU to reach higher efficiency with increasing capacity. This is same for desktop PSUs.
Here's the energy efficiency rating chart from Energy Star PDF:
