The charger with a temperature alarm packs smart sensors that watch both inside and outside heat, sounding an alert if things get too hot. That extra eye on heat stops overheating and keeps charging safe. Green Oceans temp-guard design, found in its portable EV unit, also tweaks the charge speed or cuts power completely when needed. It teams up with built-in heat vents so the charger runs from -30C to 60C without missing a beat. These layers of protection boost the units trustworthiness and life span in harsh weather.
