3000 W Step-Up/Down Inverter

The Rockstone Power RT3000W converts AC voltage between 110-120 V and 220-240 V for worldwide equipment use. It delivers a peak output of 3000 W and includes a 5 V USB port alongside 120 V and 220 V AC sockets. A built-in circuit breaker and full-range fuse protection guard connected devices.

Replaces Single-Voltage Supplies

This unit replaces the need for separate step-up and step-down transformers by handling both directions in one enclosure. The jump is worth it when appliances rated up to 1000 W require a safety margin of at least 50 % above their listed consumption. Metal casing and a hardwired grounded cord suit heavy-duty or industrial environments.

Suits Global Appliance Deployment

Buyers powering imported electronics, machinery or household items across voltage regions will find the simultaneous three-mode output practical. It is not for users needing continuous-watt ratings higher than the documented peak or those requiring DC input from batteries rather than AC mains.

Questions about this item

What input plug and voltage range does the RT3000W need on the wall side?

The hardwired cord ends in a USA grounded 3-prong plug and accepts 110 V to 120 V input for step-up operation.

Which step do installers most often miss when connecting the RT3000W?

They forget to verify the ON/OFF switch is off before plugging in, so the LED indicator lights only after the breaker is set.

What user-replaceable part protects the RT3000W if a connected appliance draws too much current?

An internal full-range fuse provides over-current protection and can be swapped when it blows.
