6000 Watt Voltage Converter Transformer Heavy Duty Step Up/Down Power Converter 220V to 110V, 110V to 220V with 3 US Outlets, 3 Universal Outlets, LCD Display, Circuit Breaker ProtectionCarbonfree Certified

Moved to Europe and wanted to bring my Breville espresso machine. Settled on this 4000W converter because of it automatically setting the correct conversion based on input, and thus no switches to flip, and no risk of getting it wrong. No annoying noise or smell, does not get warm. Sure, takes up space and is heavy, but that comes with the territory and actually looks better than many of its competitor. Havde used it daily to make 4-6 lattes for two weeks and continues to work silently and reliably. I do switch it off between use: switch off espresso machine, then the converter, than the outlet - reverse when starting using it.NOTE: I gave this transformer 5 stars, but during the posting it somehow reverted back to 1 star. I have tried to correct it sevel times with edits (including this one) - This is a great product - I am so sorry to the manufacturer/seller

I recently purchased the OLTEANP 4000W Auto Voltage Transformer, and I couldn't be more satisfied with its performance. This heavy-duty step up and down power converter is exactly what I needed for my international appliances.The automatic voltage identification feature is incredibly convenient. It detects the input voltage power source automatically and adjusts to provide the correct output power. This ensures that all my devices run smoothly without any risk of damage.One of the standout features is the LCD screen display, which not only shows the output voltage but also displays trouble codes. This makes troubleshooting a breeze, giving me peace of mind that my devices are protected.With 3 US sockets and 3 universal sockets, this transformer can handle a variety of appliances, from rice cookers to blenders, within the converter's rated power. The 4000VA capacity is perfect for my needs, allowing me to use it in both 110V and 220V countries without any issues.The premium fuse protection adds an extra layer of safety by cutting off the current if the transformer is overloaded. This reliable circuit ensures stable performance and simple operation. I also appreciate the silent working feature; it operates without any annoying buzzing noise, making it even more convenient to use.The high-quality metal casing and stable coil make this transformer a durable and reliable solution for converting voltages. Just remember to choose a transformer with a capacity 1.25 times the power of your appliance to avoid any issues.Overall, the OLTEANP 4000W Auto Voltage Transformer has exceeded my expectations in every way. It's a high-quality, reliable, and convenient solution for anyone needing a versatile power converter. Highly recommended!

This converter is a very great product. I use it for my home to convert from 110to 220. It works very greatly. I even recommend for my family and friends most of us have the same product that’s needs to convert it 220 so everyone loves is a thank me to introduce them this converter. I also thanks this converter company behalf of my family and friends. Great converter. I recommend for anyone who needs to convert from 110 to 220.

I bought this and had it shipped to the Philippines however it never worked so I contacted the seller and had a new unit shipped after verification that the first unit was shipped back. The second step up/down converter arrived and didn't work. Neither turned on or showed any lights on the LED screen. I tried several wall plugs but no luck so I sent that one back for refund. I can not recommend this converter.

Be careful. Not a toy, it works read directions make sure your 110 electrical product good quality. I have been using converters for over 8 years. i live international. Love my American mixers, ovens countertop etc..

I purchased 3 sewing machines from China, the motors of which need 220V AC in my tailor store. But my store only has 110V AC, so I cannot drive the machines. My friend refers the OLTEANP 4000 Watt Voltage Converter resolved my issues. OLTEANP voltage converter is a high-quality inverter that makes you worry-free. It can auto-magically fit your power, whether it's 110V AC or 220V AC, and provides a powerful, stable output with 3 outlets in 110V AC and 3 outlets in 220V AC.An easy-to-read LED display screen lets me know the current power status. This feature makes the converter reliable and user-friendly and 4000 Watt convert provides heavy-duty output for my sewing machines.It's the best investment for my tailor store, but it's not just for my sewing machines, after I found the convert is working, my wife also purchased a rice cooker and some other appliances from the online store , which also need 220V AC as power. With an OLTEANP voltage converter, I never worry about my wife's purchased appliances that cannot work with different power requirements.

Works!!! I tried 4 other transformers to power a 3000w outdoor commercial infrared heater. The others either started to smoke and almost caught fire - or blew the 20 amp breaker in the first two minutes. This transformer is high quality. It’s only 7 inches wide, has a digital display for the voltage - and has had zero issues powering this heater. The heater draws 15 amps at 60Hz. This is the only upconverter that’s been flawless. The value for the money I saved as opposed to $1000 in electrical work was a huge bonus as well.

Purchased one 6-mo ago. It worked well. Purchased a second, but have not tested it. BE AWARE the input plug is designed for 120VAC x 15Amp (common US residential outlet). That means it can supply only 1800W before tripping typical residential circuit breaker. HOWEVER, when used on 240VAC circuit (Europe and much of world), it performs as a step-down transformer and outputs 120VAC, and it has the potential to output up to 3600W (240V x 15Amp), but you'll need a plug converter to adapt common US plug (2 vert spade + grd) to Euro plug (2-pin + gnd or similar).
