Smart sensors watch both the inside and outside of the unit, reading temperatures every second. If things get too hot, the charger either slows down or beeps, so there are no burned wires or melted cases. Green Oceans design adds fins and vents, letting the unit run from -30 to +60 C without breaking a sweat. This temperature smarts protect the electronics, stretch their lifespan, and keep performance high in ice, heat, or anything between.
