It offers selectable input voltages (110/120V or 220/240V) and simultaneous dual outputs (110V US standard and 220V universal), ensuring versatile compatibility with global appliances. Equipped with all-range fuse protection and spare fuses, plus an American plug adapter, it delivers reliable, safe voltage conversion for demanding power needs. ## Description Made by one of the leading manufacturers in the industry, the Topow ST Series step up / step down voltage transformers offer you a safe, reliable, affordable and convenient solution to converting voltages from 110-120 volts up to 220-240 volts, or from 220-240 volts down to 110-120 volts for both home use and industrial applications. The ST-3000 is rated at 3000 watts maximum. It features a heavy-duty cord with a standard round prong plug plus a free American Flat outlet plug adapter. There are a total of two outputs on the front panel. Two are grounded outputs, one designated for 110 volts with a US standard outlet, the other for 220 volts only with a universal outlet. Also uses a protective standard fuse for extra safety. The manufacturer recommends you purchase a transformer that is 25% higher then the wattage you need. You should know that you will never damage your appliance with a higher voltage transformer, however if you buy one that is nor powerful enough, it will not work. Remember to leave at least a 100% slack for the transformer. Using them to maximum capacity will eventually burn the transformer out after prolonged use. Some items, such as laser printers and power tools spike when you turn them on. For these types of situations you need to buy a transformer that is at least 3 times the items capacity. Review: good - Very good product. Review: This product is dangerous - II use my Tefal steamer form another country 220v and suddenly I started to smell burning smoke. There was smoke coming out of the outlet and the plug was melting. This product is dangerous and can set your house on fire. ## Features - Input Voltage: 110/120/220/240 V/AC Selectable - Output Voltage: 110 or 20 V/AC Selectable - Simultaneous 2-Mode Output 120V (Standard US Outlet) / 220V (Universal Outlet) - All Range Fuse Protection With Two Spare Fuses Included - American Plug Adapter Included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E9FCF0U | | Best Sellers Rank | #1,640,422 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #7,601 in Power Converters | | Brand | TOPOW | | Brand Name | TOPOW | | Customer Reviews | 4.3 out of 5 stars 8 Reviews | | Manufacturer | Ningbo Jinyuang (G.S) Electricity Co., Ltd. | | Model | ST-3000 | | Mounting Type | Wall Mount | | Part Number | ST-3000 | | Power Source | AC | | Specification Met | UL | | UPC | 798295517951 | ## Product Details - **Brand:** TOPOW - **Mounting Type:** Wall Mount - **Power Source:** AC - **Specification Met:** UL - **UPC:** 798295517951 ## Images ![3000 Watt Voltage Transformer 3000 Watt Step Up and Down Converter - Image 1](https://m.media-amazon.com/images/I/51Lzl6my0-L.jpg) ![3000 Watt Voltage Transformer 3000 Watt Step Up and Down Converter - Image 2](https://m.media-amazon.com/images/I/514cRxGPFsL.jpg) ![3000 Watt Voltage Transformer 3000 Watt Step Up and Down Converter - Image 3](https://m.media-amazon.com/images/I/51OJNFYuAKL.jpg) ![3000 Watt Voltage Transformer 3000 Watt Step Up and Down Converter - Image 4](https://m.media-amazon.com/images/I/51LfD0L9OHL.jpg) ![3000 Watt Voltage Transformer 3000 Watt Step Up and Down Converter - Image 5](https://m.media-amazon.com/images/I/41o0W0seMdL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good *by J***3 on February 1, 2020* Very good product. ### ⭐ This product is dangerous *by D***N on September 24, 2017* II use my Tefal steamer form another country 220v and suddenly I started to smell burning smoke.
