It works well and looks high quality. My only suggestion is to keep it turned off when you’re not using it to avoid unnecessary electricity consumption. Overall, I’m very happy with this purchase. Review: Great converter. Exceeded expectations after several months of usage. - We have several step ups. The ones we have caused our DeLonghi coffee maker to hum, but this UMI got rid of the sound. Our cofee maker is not made for 110v so the trick is to power off the converter each time and allow the coffee maker to discharge.. This is not a defect of the converter but rather the components in our coffee maker. We have another DeLonghi cofee maker but the coffee is better on the one connected to the UMI and worth the extra step. We would clearly buy this product again. ## Features - 【FULL POWER】Intermittent rating of 4600W - duty cycle 5mins on/15mins off. Continuous Rating 2400W. Unlike other compact converters or bulky voltage converter that stated 2000W can only work with 1600W appliance. Or stated 3000W, but can only work with 2400W. We say 2400W, then the power rating is 2400 watts, you can run your 2400W device continuously. - 【PREMIUM QUALITY】 Built-in high-performance toroidal transformer, which uses toroid core and pure copper coils. The 2400W 110v to 220v converter weighs 8.4kg, which is compact and functional, quiet and efficient. With high quality transformer, the voltage converter has stable output and low consumption. - 【MULTI-FUNCTION】UMI Power Converter 110v to 220v works with kinds of 220v or 230v electric appliances, devices and equipment. Such as hair dryer, coffee maker, rice cooker, blender, mixer, air fryer, toaster, robot vacuum and so on. - 【SAFETY】ETL and CE Certified! Multiple Protections. Our UMI voltage converter has surge protection, over power protection, over-current protection, thermal protection, overload protection, short circuit protection, anti-leakage protection, anti-trip protection, anti-fall protection.

Most US house circuits are not rated at even 20AMPS (this is why US kettles take so long to boil water by comparison with European kettles). Use at full rated power for short periods is OK but I would strongly advise running long periods at full rated power - especially if the house has older wiring - unless you know the circuit is wired for 20 AMPS. **Q: If the input voltage is 220v/50hz, will it be able to produce 110v/60hz?** A: No, we have another item 220V to 110V step down voltage converter to produce 110V, you could check on Amazon. **Q: Can it transform frequency from 60hz to 50hz in US? or transform voltage only ?Can i use it for 220v 50hz tube amplifier?** A: All most all converters in this price range do NOT convert the frequency, i.e. USA 60 Hz to EURO 50 Hz. However, for many electronic devices such as TVs, monitors, (radios, computers, etc., and for "non-inductive" loads (lamps, small heaters, etc) these converters work fine. For "Inductive" loads - things which have transformers or motors such as sewing machines, fans, motorized small kitchen appliances - the devices may buzz and / or fail prematurely because the wire windings in the transformer or motor were designed to work with 50Hz not 60Hz. In the specific case of a tube amplifier, it depends on the amplifier's power supply - most of these have transformers - so it might act as mentioned. Usually wrong frequencies into a transformer will cause them to produce more heat than normal - make sure you supplie ample cooling, e.g. add a fan. (Electrical Engineer here) **Q: is this device like a power bank or do you have to have it plugged in while using it** A: yes, you need.to plugged in while using it. is not a power bank. in china is 220v in U.S 110v i need that input 110v and output 220v ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Quality and Stylish *by H***D on July 22, 2026* This is a really great and stylish voltage converter.

Unfortunately it didn't, and I was stuck with a 220v only 1500w rated device that had a Chinese Type I plug. A great deal suddenly was not looking so great. I was determined though, I was going to make my Xiaomi work, so research I did, and half a day later, I decided on this beauty of a transformer. I found out all the things like needing a step up transformer rated for more than the max wattage of my device, so I went with the 2400 watt model, which handles everything with ease. Also looks nice and fits into the decor well. Also found out that 220v American devices like our electric stoves and washing machines are not the same kind of 220v European and Asian devices, so adding an american 220v outlet would be incompatible. I decided not to worry about the 50/60hz difference, hopefully that's okay, but this device converts my 110v outlet to the kind of 220v outlet that Euro/Asian devices need. I could have got an ugly one for $90 instead of $120, but I'm glad I spent the extra. This thing is wonderful, and I may find more uses in the future. ## Frequently Bought Together - UMI 2400W Step Up Voltage Converter, Heavy Duty Power Transformer for Large Capacity Devices, Europe Appliance 110v to 220v - UMI 2000W Step Up Voltage 110v to 220v Converter, Voltage Converter 110v to 220v for Large Capacity Device Up to 4000W, Step Up Converter 110v to 220v with Pure Copper Coils- Transformer 110v to 220v - UMI 110V to 220V Step Up Voltage Converter LX-300C Toroidal Transformer for 220V Appliances to Be Used in US, Simple White Plastic Shell, Safe and Effective --- ## 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.za/products/47237519-umi-2400w-step-up-voltage-converter](https://www.desertcart.co.za/products/47237519-umi-2400w-step-up-voltage-converter) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-22*
