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: It works in Nigeria. Thank you.

Thank you. ### ⭐⭐⭐⭐⭐ Review *by K***Y on 15 August 2021* Works great with my airfryer ### ⭐⭐⭐⭐⭐ Review *by R***D on 24 July 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. --- ## 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.sn/products/586070237-dynastar-step-up-and-step-down-voltage-converter-and-transformer](https://www.desertcart.sn/products/586070237-dynastar-step-up-and-step-down-voltage-converter-and-transformer) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-14*
