Enerdrive 12v 400w PSW Inverter delivers reliable, clean AC power from your 12V battery, tailored for life on the move. Whether you’re at home, on a boat, in a caravan, or behind the wheel of a 4WD or commercial vehicle, this compact unit makes it easy to run essential appliances with confidence.

  • True sine wave output (230 VAC, 50 Hz) that is gentle on motors and electronics, reducing stress on surge protection circuitry and potentially extending the life of connected devices.
  • 1x Australian-style GPO outlet plus USB 5V 1A for convenient charging of phones, tablets, and small peripherals.
  • High surge capability—handles start-up surges for demanding loads by delivering up to 2x the continuous power when needed.
  • Automatic shutdown protects the inverter and your battery from overload, overheating, and incorrect battery conditions.
  • Ignition Start terminal enables turning the unit on/off with a +12V signal, integrating neatly with vehicle wiring and other control systems.
  • Durable, installation-ready design with mounting brackets, heavy-duty DC battery stud connectors, and included high-quality DC cables (HD alligator clips & 12V socket cable).
  • Efficient power conversion maximizing the amount of battery power that becomes usable AC power, so you can run more devices longer.
  • Safety at a glance built-in indicators and warning/error codes help you monitor inverter health before any fault triggers an shutdown.

Why this Enerdrive ePOWER 400W Inverter is different

Designed for real-world use, the Enerdrive ePOWER 400W inverter combines compact size with robust performance. Its true sine wave output ensures compatibility with sensitive electronics and motor-driven loads, while a high surge capacity keeps your gear starting reliably—an edge over basic modified-sine alternatives. The automatic protection features prevent battery drain and equipment damage, giving you peace of mind during off-grid adventures or on-site work setups.

Ideal use cases

Perfect for campers, boat owners, caravan travelers, and professionals who need dependable AC power where mains aren’t available. Use it to run a compact fridge, laptop, TV, power tools, or a small kettle—anything within the 400W continuous rating. The 5V USB port adds convenient charging for your mobile devices, while the unit’s compact footprint makes it easy to mount in vehicles or utility spaces.
