Half Life 2: Episode 2 Easter Egg - Old Hev Charger

You can find that model in room, where Alyx brings a cup of tea to Eli. When Eli sits on couch, on the right there is small storage (some boxes and wood fenced) in there, behind the boxes it sits and waits for you to pass it. Just shoot the boxes or use cheats and get it. This 3D model of front panel of hev suit charger can be also found in original Half Life 2 in black mesa scrapyard, when you get the gravity gun. That type of hev suit charger was first seen in old Half Life 1 on the wall(usually next to medical station or health charger), giving you free energy for your suit.
