## Description

Buy UMI 300W 120V to 220V Step Up Voltage Converter, Step Up 110V to 220V, Work with 220-240V Appliance in US, Safe and Effective: Isolation Transformers - desertcart.com ✓ FREE DELIVERY possible on eligible purchases

## Features

- Space-saving & Non-slip Design: The 120V to 220V converter measures 8.46" x 6.02" x 1.97"(21.5 x 15.3 x 5 cm) including the base, which is about the size of an A5 sheet of paper. It can be easily placed on a shelf or tabletop, effectively saving space. The base is equipped with a non-slip silicone pad, ensuring the device grips the desktop firmly and preventing accidental falls, even if the cable is tugged
- Pure Copper Coil: Why does this step up converter weigh 5.5lbs(2.5kg)? This is attributed to its built-in high-performance toroidal transformer, which utilizes a toroidal iron core and pure copper coils rather than cheap aluminum. This sense of substantiality implies quiet and efficient operation. Please note: This is not a portable adapter
- Stable Conversion: The step up transformer is specifically designed for countries that use 110V (such as the United States, Canada, and Mexico), allowing you to use appliances from countries that use 220V (eg. Europe, China, South Korea,etc.). It is compatible with low-power appliances operating at 50/60 Hz, such as mobile phones, computers, audio, etc
- Dual-socket Output: The step up voltage converter is designed with two universal output sockets that can be used simultaneously. Please note that this transformer has a rated power of 300W. We recommend that the maximum power of your device not exceed 240W. Be sure to verify the total power consumption of all connected appliances to ensure it does not exceed the converter's capacity limits
- Multiple Functions: CE & CQC Certified. The 120 to 220 transformer features a built-in microcomputer control system that provides multiple layers of protection, including thermal, fuse, overload, and short-circuit protection. It also has a built-in spare fuse that you can replace if the fuse blows due to an overload
