This version, model number HAC-001(-01), has the same battery as the original Switch, but the CPU is now more efficient. This is why battery life is around double of what the original system offered.
In the box you will get:
* Nintendo Switch tablet
* Joy-Con Controllers
* Joy-Con straps
* Nintendo Switch Dock
* AC Power Adapter (with type C connection)
* Nintendo-branded HDMI cable
Apart from the new model number being displayed in the back, this new version looks identical to the original. As such, it will work with all original Nintendo controllers, cases, screen protectors, and other accessories.
I've played the Switch a lot at my friend's house. It's a great system. You can play on the move, with friends on a train, or on your television using the docking station. This makes it a better option than the lite in my opinion, particularly as battery life is longer.
