Giantz 2500W Pure Sine Wave Inverter – Heavy-Duty 12V to 240V Power for Off-Grid Living, Touring and Backup Use

The Giantz 2500W Pure Sine Wave Inverter delivers clean, stable 240V power straight from your 12V battery, making it an ideal solution for off-grid setups, caravans, mobile workstations or home emergency backup.

With a 2500W continuous output and 5000W peak surge capacity, it handles larger loads while keeping sensitive electronics like laptops, phones, fridges and TVs running safely.

The pure sine wave output means no flickering, buzzing or risk to your equipment—just reliable, home-grade power wherever you are.

Engineered with IGBT inverter technology and quality Japanese components, this inverter runs at up to 90% efficiency, so you get more usable power from your battery without unnecessary draw.

It features dual Australian-standard 240V sockets, a 2.1A USB port, and an LED display to monitor status at a glance.

You can operate it manually or use the wireless remote control, giving you flexibility when it’s mounted out of reach.

It’s packed with smart protections too—guarding against overload, over-voltage, overheating, low battery and short circuits—so your system stays safe under pressure.

Giantz 12V/240V Pure Sine Wave 2500W (5000W Peak) Power Inverter Reviews

Frequently Asked Questions

Can the Giantz 12V/240V Pure Sine Wave 2500W Power Inverter run all types of appliances?

The Giantz Power Inverter is ideal for powering sensitive electronics and 240V devices such as computers, TVs, and smartphones. However, it is not suitable for inductive devices that contain motors or transformers, such as air conditioners or compressors, as these can overload the inverter and potentially cause damage to the motor and electronic boards.

How do I know if the inverter is safe to use with my battery?

This inverter is compatible with 12V batteries and has multiple safety features, including low battery alarm and shutdown, over-voltage protection, and short circuit protection. It is designed to prevent damage to both the inverter and connected devices by automatically shutting down in cases of low or excessive voltage, overheating, or short circuits, ensuring safe operation.

How efficient is this inverter, and does it drain the battery when not in use?

The Giantz 2500W Power Inverter operates at approximately 90% efficiency, maximising power output while minimising energy loss. When not in use, it draws a minimal standby current of 0.5-1A, which has a negligible impact on battery life, though it’s recommended to disconnect the inverter if it won’t be used for an extended period to conserve battery power.
