500W Pure Sine Wave Voltage Converter US to Europe, 220V to 110V Converter for European Travel, Power Converter Adapter Combo PD for CPAP Hair Straightener Cruler Shaver Toothbrush Laptop Camera Phone

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.

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.

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.

Not great instructions, but once figured out, these worked. We bought 4 of these for our large family trip abroad.

Worked perfectly. I used during my trip across Europe.

UK USER: the adapter does exactly what it says on the box. I wanted the 60hz functionality in particular because I want to use it with some frequency sensitive equipment in the UK and most voltage reducers work at 50hz when plugged into UK mains. Runs cool, fan rarely comes on and is quiet when it does. Added bonus was 4x multi adapters that I wasn’t expecting but tbh may never use. All-in-all well pleased.

I recently took the converter with me on a trip to Europe, and it was an absolute game-changer! I burned multiple devices in the past since overseas have 220V and not all devices can take the difference. I needed something reliable to handle a range of devices: my CPAP machine, laptop, phone, and various electronics. This converted saved me a lot of many. I did some research and 100% pure sine wave output ensured everything ran smoothly without risking my more sensitive devices. It's surprisingly compact and didn’t take up much space in my luggage. I also loved that it includes both adapter plugs and USB ports, making it a convenient all-in-one solution. If you're planning to travel and want to be safe I highly recommend the this converter. Don't be cheap or you will pay much more in the long run. It performed flawlessly and saved me so much worry!

New Details. I was outside the return window for returning the product through Amazon. Team Doace reached out to me and initiated a return. Once they received it a PROMPT refund was ISSUED. Thank you Doace for standing behind your product 100%. You are an honorable company and a pleasure to business with. If anyone is considering buying this product I recommend it. Anyone can receive an electronic item that malfunctions. It just happens. I am giving them 5 stars as a review because they earned it. I bought it for our upcoming trip to Europe. The USB C ports do not work. iPhone flashes too much voltage so they are useless. I bought it to give my CPAP a 120V supply which it did. I am hoping that the rest of the converter keeps working to do just that for the remainder of the trip. Even though it was purchased on 4/11 and my trip started on May 15 it is only been used for 6 days of use. I am out of my return window. To make this right I want either a return or a replacement.

Finish is average ... But gets ur job done.
