Product details

ROCKSTONE POWER stands for quality, technology, and innovation in power solutions. This 5000 Watt voltage converter transformer is built to handle diverse voltage requirements across the globe. Its rugged metal casing and thoughtful design bring practical, real-world versatility to travelers, remote workspaces, and hobbyists who rely on electronics in different countries. While it’s designed to support a broad range of devices, users should evaluate their specific wattage needs and startup surges to ensure proper compatibility.

Key capabilities

  • 5000 Watts heavy-duty step up / step down transformer for 110–120V to 220–240V and vice versa
  • Patented simultaneous 3-mode output: 110V USA socket, 220V universal socket, and a 5V USB port
  • Durable metal casing with an ON/OFF switch and LED indicator for clear status
  • Hardwired insulated power cord with a grounded 3-prong plug for safe connection
  • CE certified with full-range fuse protection and over-current protection

Practical scenarios

Use cases span international travel, home workshops, and small offices where devices require different voltages. The 3-mode outputs let you power compatible devices without multiple adapters, while the USB port enables convenient charging on the go.

  • Power laptops, cameras, drones, or hobby gear that need voltage conversion
  • Support for tools or equipment in countries with 110–120V or 220–240V mains
  • Flexible charging for mobile devices via the built-in 5V USB port

Safety and setup tips

Choose a transformer with headroom: pick a unit whose max wattage is at least 50% higher than your appliance’s rated watts. Heaters and motors may have higher startup requirements, so plan accordingly.

  • Verify appliance wattage and potential startup surges
  • Place the transformer in a ventilated, dry area away from moisture
  • Use the grounded plug and ensure proper, secure connections

What’s in the box
