500W Pure Sine Wave Voltage Converter US to Europe, AI 220V to 110V Converter 50Hz to 60Hz Transformer for European Travel, Power Converter Adapter Combo USB-C for CPAP Hair Straightener Laptop Phone

I bought this 500W Pure Sine Wave Voltage Converter for my trip to Europe, and it worked flawlessly. It converts 220V to 110V safely, so I was able to use my US devices like a CPAP machine, hair straightener, shaver, and laptop without any issues. The pure sine wave design gives me peace of mind since it’s much safer for sensitive electronics like cameras and phones. It also has multiple output options, including USB and PD ports, which made charging my phone and tablet super convenient while traveling. It’s compact, lightweight, and easy to pack, yet powerful enough to handle higher-wattage devices like a hair straightener. Overall, this converter is a must-have for anyone traveling from the US to Europe who needs a reliable power solution.

I'm glad I bought this unit! It is working well here in Ireland and keeping stuff charged up at hotels. I use it to charge the Vive mobility scooter and all our electronics simultaneously. I particularly like that it provides standard 110v outlets, as well use USB outlets, including two PD USB-C ports. Anyway, if you travel internationally, get one! This is a pure sine wave converter, so better for your expensive electronics than using a cheap plug adapter thing that depends on your device to do the voltage conversion, and avoids you having to wonder if your device will get fried when you plug it in directly to 220v. In my opinion, the extra volume and mass is worth the peace of mind. Minus one star because I do wish it had a better storage case though. Instead of a draw string bag, a plastic box with compartments/spaces for each adapter would be better. For many items, including this one, a proper storage case really adds a lot of useful value.

Needed for my Trip to Japan and Korea and works well. IT WAS NEEDED!

I use this to power and Oster 76 as it only works on 60hz or otherwise the motor can overheat. Only used it once so far, but so far so good

The product does not charge my Nikon Z9 battery without dropping out. The Nikon Z9 battery charger requires a PD supply source. I regularly charge my Nikon Z9 battery with two different wall plug in PD sources I bought on Amazon with no supply drop outs. I also regularly use my PD battery brick and car PD port to charge the Nikon battery reliably and consistently. At first, I thought the problem was only with port C1 on the product since I did not notice C2 having an issue. I initiated a return and placed a new order. Alas, I noticed both C1 and C2 both drop out on the replacement unit. Update June 12, 2024. The seller did contact me once and asked for information about the Nikon Battery and Nikon Charger that I use. I responded to the seller with the specific links to the Nikon Battery and Charger approximately on May 14, 2024. The seller never responded. My return window closed on June 9. I am very disappointed that the seller provided no further assistance or reason why the DOACE 350W does not reliable charge a PD device that can be charged normally with so many other PD rated chargers. Update July 12, 2924 About a week ago, I received a msg from DOACE that the original unit I received had a defective solder connection. I was sent a replacement device which arrived within 24 hours of being notified. I had several follow up questions that I submitted to the customer representative. Each response was very swift. Answers were extremely clear and included some very helpful details. In summary, yes, I was disappointed at first, but am now extremely satisfied with the excellent customer service and the solution. And, yes, I now recommend this very functional and versatile product.
