Packaging
The main box is a quite flat one. It contains two smaller packages—one for the laptop and its 280 W charger. The less powerful configurations come with 200 W chargers. It's unclear whether these are GaN models, which offer higher efficiency and are thus smaller and lighter. Razer does offer these GaN units on it's store, so it's certainly a possibility.
By the way, the charger may look big (18 x 8.2 x 2.4 cm), but it's not exactly huge. Still, it weighs 696 grams which isn't light at all, but I've seen heftier chargers too.
