myCOOLMAN Pure Sine Wave Inverter Charger 12V · 3000W / 125A

Description

The myCOOLMAN Energy Inverter Charger Pure Sinewave 3000W powers appliances and sensitive electronics from a 12 V battery bank in caravans and other recreational vehicles. It delivers stable 220/230 V AC pure sine wave power, with 3000 W continuous output and time-limited boost output for higher-demand loads.

When mains power is connected, its integrated adjustable 1500 W multi-stage charger recharges the battery bank. The manual specifies 125 A continuous charging, with the advertised 150 A rating applying at 10 V. An automatic changeover switch transfers the AC supply between mains and inverter power. The lightweight aluminium housing weighs 7.2 kg, helping manage payload in caravan installations.

Bluetooth connectivity allows remote monitoring and control through a smart device. Built-in protections guard against common electrical faults, and the operating temperature range is -25 °C to +55 °C. An optional digital display is available separately for enhanced visibility and control.

This is a hardwired inverter charger, not a portable power station with plug-in appliance sockets. Install it indoors with unobstructed ventilation, and set the battery selector to match the connected battery type before use.

Our Comments

The manufacturer's stated maximum charging power (1500 W at 150 A @ 10 V) represents ideal conditions and theoretical maximum values. This would only apply to a fully depleted battery. Realistically, actual charging current at typical battery voltages (~12 V) will be lower — around 125 A — to remain within the charger's 1500 W power limit. Charging current naturally reduces as battery voltage increases during charging.
