Eco Power Bank
It can power buildings via Large Dischargers or Compact Dischargers.
Duplicants can produce new Eco Power Banks at the Soldering Station.
Must be kept dry.
A Power Bank holds a small amount of energy and can power Bionic Duplicants, Flydos, Compact Discharger or Large Discharger. All Power Banks have a capacity of 120 kJ.
Eco Power Banks are made in the Soldering Station with 200kg of Abyssalite, and start out as Empty Eco Power Banks. To fill or refill Empty Eco Power Banks, a Power Bank Charger is used.
Power Bank chargers consume 480 W of power, but only delivers 400 W into the Eco Power Bank (a -80 W inefficiency). As Eco Power Bank has a capacity of 120 kJ, charging one will take 300 seconds.
When reaching 0 kJ, an Eco Power Bank will be replaced by an Empty Eco Power Bank. Eco Power Banks weigh 20 kg.
In contact with water-based liquids, charged Eco Power Banks rapidly take damage, exploding on death. On death, it drops Power Bank Scrap, which can be recycled into Abyssalite at the Rock Crusher. Empty power banks do not take damage.
Strategy
Each Power Bank Charger can fill 2 power banks every cycle, as bionic duplicants consume one power bank every cycle or 200 W continuously it is best to put one charger for every 2 duplicants.
Eco Power banks are typically the preferred method of charging bionic dupes or flydos, the other applicable power banks will drain a lot of your metal supplies.
