The Portasol is an item that can be crafted and used only by Winona with the Founder's Keepers II skill. Winona can get the recipe if using the Calibrated Perceiver on one of the Unstable Transmissions. It will lose energy after every teleport (7%) and while equipped in hand. The Portasol will not break when its charge drop to 0. When dropped near Winona's Generator or Winona's G.E.M.erator, it will slowly recharge. It takes 1 in-game day to fully recharge, or 0.5 days if the generator is made by a Winona with the Quick Charge skill.
Although only Winona with the Founder's Keepers II skill can teleport with it, any character can equip the Portasol for its 35% Wetness and Lightning protection.
Winona players with Founder's Keepers II skill can use Portasol to teleport to the nearest powered Teletransport Station. If there is more than one Teletransport Station, using the Portasol while standing on one of Teletransport Stations will teleport to the other nearest Teletransport Station. Unlike Wanda's Backtrek Watch, Winona cannot teleport between shards (i.e. across Surface World and Caves).
When a player is teleporting, it can also teleport dropped items and mobs (that can be put in the player's inventory) that are very close to them. This includes heavy items, such as the Suspicious Marbles or Giant Crops. The player can also teleport while sitting on a Beefalo.
Tips
Unlike its equivalent in the Hamlet DLC, the Telebrella, the Portasol has infinite range.
When there is no powered Teletransport Station in the world, teleporting with Portasol will make Winona disappear and reappear at the same spot. This can be used to dodge some attacks.
