Multiple appliances can be used with the same transformer, as long as wattage capacity is not exceeded Works for virtually any plug from anywhere in the world, with the exception of US 220/240 volt outlets (usually found on commercial products like washers and dryers) Five year limited manufacturer warranty HOW DO YOU KNOW WHICH CONVERTER YOU NEED? Check the total wattage consumed by your electrical devices and multiply that number by 3. You need a converter at least 3x the watts of the devices to leave enough room for surges in power they may utilize. To determine the correct wattage allowance of the voltage converter/transformer you need, first identify the wattage of the electronic devices or appliances you plan to use. This information can be found on the manufacturer's label located on the back or bottom of the device or appliance, or in the specifications section of the appliances' owner’s manual. Note: Watts may be listed as “W” on your appliance. If you can't find “Watts” or “W” on the label, you may find “Amps,” also known as “amperage” or “A”. If only the amperage is shown, multiply the input voltage by the amperage to find the wattage. Use the following example as a guide: Volts x Amps = Watts or 110V x 1.5 A = 165W. After totaling the watts of all the devices for use with the transformer, add up the total watts and multiply that number by 3. Review: Works Great - Moved from the U.S. to Europe and decided to bring some great kitchen electronics we had with us. This allows us to use things like rice cookers, mixers, etc. it works great and is able to handle the voltage difference here. It’s large and heavy, but so are some the appliance we plug into it. Makes no noise while operating. Review: Stabilizer - It works in Nigeria. Thank you. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FTAXJA8 | | Best Sellers Rank | #281,043 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,171 in Power Converters | | Customer Reviews | 4.4 4.4 out of 5 stars (437) | | Date First Available | May 17, 2016 | | EU Spare Part Availability Duration | 5 Years | | Is Discontinued By Manufacturer | No | | Item Weight | 16.5 pounds | | Item model number | DS-3500 | | Manufacturer | International Diamond Series | | Package Dimensions | 11.46 x 8.78 x 7.36 inches | | UPC | 076998135000 | ## Product Details - **Brand:** International Diamond Series - **Current Rating:** 1.5 Amps - **Mounting Type:** Floor Mount - **Power Source:** Corded Electric - **Specification Met:** certified frustration-free ## Images ![Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Lifetime Coil, 5-Year-Warranty, 3500 Watts - Image 1](https://m.media-amazon.com/images/I/61w4l3Tb3SL.jpg) ![Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Lifetime Coil, 5-Year-Warranty, 3500 Watts - Image 2](https://m.media-amazon.com/images/I/61HuwIpZW-L.jpg) ![Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Lifetime Coil, 5-Year-Warranty, 3500 Watts - Image 3](https://m.media-amazon.com/images/I/615Aa3+aISL.jpg) ![Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Lifetime Coil, 5-Year-Warranty, 3500 Watts - Image 4](https://m.media-amazon.com/images/I/61SMhITU70L.jpg) ![Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Lifetime Coil, 5-Year-Warranty, 3500 Watts - Image 5](https://m.media-amazon.com/images/I/618QByCDumL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great *by D***. on July 8, 2024* Moved from the U.S. to Europe and decided to bring some great kitchen electronics we had with us. This allows us to use things like rice cookers, mixers, etc. it works great and is able to handle the voltage difference here. It’s large and heavy, but so are some the appliance we plug into it.

Thank you. ### ⭐⭐⭐⭐⭐ Voltage converter- extremely heavy otherwise great product *by R***D on July 24, 2025* Great product. Needed to buy after purchasing an iron that came from Germany that had voltage of 220 rather than the 100 voltage common in the US. The more wattage you need the more expensive so it was a bit pricey. I like that you can switch from 110 to 220 & vice versa. The one drawback is it is extremly heavy, too heavy to travel internationally with & the carring handle is a strap on top that I can barely get my hand under it so I need to pick it up & carry it as I would carry a hevy box. ## Frequently Bought Together - Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Lifetime Coil, 5-Year-Warranty, 3500 Watts - Yinleader 1500W Step Up & Step Down Voltage Transformer Converter 110V to 220V or 220V/230V/240V to 110V/120V Power Converter w/US Power Cord,Circuit Breaker Protection --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/31677518-dynastar-step-up-and-step-down-voltage-converter-and-transformer](https://www.desertcart.co.uk/products/31677518-dynastar-step-up-and-step-down-voltage-converter-and-transformer) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
