All health chargers were originally inspired by Half-Life 2's wall charger. The original description for the Portable Health Charger was something along the lines of "Half-Life 2's health charger. Now portable! Restores all HP."
The plan in Codename: Video Game Caper is for these items to be a rarity, so they will probably do the same thing that they do in Origins.
