DOACE 220v to 110v Voltage Converter for European Travel: Max 500W Pure Sine Wave Voltage Converter US to Europe - 220 to 110 International Power Adapter Plug Combo Step Down Transformer Black

My son was going on a school trip with the band abroad and needed a voltage converter. He wanted to use his laptop and of course his cell phone while over seas, so we wanted one that we knew would offer the best protection possible. We really liked this converter because of its pure sine wave power output, which ensures a smoother, cleaner power supply. This type of power is critical for sensitive electronics, such as my sons laptop and his smartphone. The built-in safety features are impressive, offering protection against over-voltage, under-voltage, over-temperature, overload, and short circuits. The converter also automatically shuts off if overloaded, with an alert system that blinks to warn you, allowing the device to cool down before resetting. This converter includes 7 charging ports, making it incredibly convenient for my son to plug in multiple devices or share with his friends. It features 3 standard AC outlets and 4 USB ports, including 2 USB-C PD 20W fast-charging ports and 2 QC 18W USB-A fast-charging ports. He said it worked great on his trip and he had no issues.

I purchased this voltage converter to use when I am traveling for business internationally. This converter is a compact device that allows me to use my electronic devices from home no matter what country I am in. It has compatibility for over 200 countries. It operates from a pure sine wave power conversion allows a stable power output. This is very crucial to maintaining proper operation in electronics as they are very sensitive.The device is equipped with three ac sockets, two usb-c ports, and two usb-a ports. I am able to charge multiple devices simultaneously without any kind of problems. It also is equipped with a universal power plug adapter. This is so convenient, allowing me to use it in the UK, US, AU, EU, IT, and many other countries without needing multiple adapters.In terms of performance the converter delivers consistent power output without any voltage fluctuations or overheating issues. I have used it to charge my laptop, phone, camera, and other devices without any problems. The build quality is solid and so far durable withstaining through my travels.I am happy with my purchase of this voltage converter overall. It has been a reliable power essential for my travels.

This product worked the way it was supposed to on a recent trip through parts of Africa.Just two things you should know:1) it has an internal fan that comes on as the unit needs to cool down. This may wake you up at night.2) If the power goes out, this unit does not come back on upon the restoration of power. So, if you are charging batteries while you are gone and there is a glitch in the power, it will not come back on until you arrive to push the button.

I took this on a 2-month journey through New Zealand and Fiji. It worked flawlessly and it was priceless! I never had to worry about frying any of my electronics.

I travel a lot to Asian and European countries and i struggle most of the times to charge my devices in transit as well as while being there. I end up most of the time relying on power banks for a short while an purchase a local adapter , which is only useful if the charges can do 220 V to 110V. Most laptop chargers can downgrade but other items can get burnt if there is no stepdown transformer. This is awesome in the sense that it can do to support till 500W. I used it on coffee machine and rice cooker which operate under 500W. This is compact , sturdy and easy to throw into cabin bags. Best part is it comes with multiple plug types and various USB ports. Love the product !

For years I've been carrying around one of those universal converter / transformer "cubes" you plug into a wall, but honestly the build quality on most I've used has been crap and after a year or two I'm throwing away because their connections on any ports seem to become more intermittent as the cheap plastic parts loosen up over time. So I decided to try something more like a "power-strip" configuration for a last-minute trip to Dubai, and the "DOACE" was the one available with overnight shipping. I was a little concerned given the relatively random brand name, and that this is a little bigger to pack, and having the cord and plug converters at first I didn't think would be ideal... but after completing my first trip I'm extremely happy with this purchase and this will easily see hundreds of thousands of miles of travel with me in the years ahead!It takes up a little more space in your bag - that's unavoidable - but the execution is so much better than those little cubes. First, since I knew what country I was flying to I just took the single plug converter for that country. The unit itself comes with an EU default plug so if I were traveling there I wouldn't have to carry any converter at all. But the transformer and multiple outlets is what really makes it. 2 USB-C, 2 USB-A, and 3 regular US electrical outlets, and the ability to plug in high-draw things like hair dryers and curling irons? Awesome! Now it seemed like the power output on the USB outlets wasn't huge - maybe 15W? - so it's not going to be a fast charger on its own for your USB gadgets. But if you have a normal fast-charging adapter for your USB devices you just plug those into the US plugs. I was using this with two Anker battery packs which have digital readouts and it worked great, and I was able to pull 60W out via the normal 120v plugs and push that into my laptop.Some people in reviews complained it's "noisy" - and honestly, I think it's a positive. So my experience was, if you're doing low-draw items the internal fan won't kick on at all and in that case it's totally silent. But once I was drawing 60W out through the normal plugs and charging up my watch or my tablet ... sometimes a fan would kick on. In my opinion, this is a GOOD thing because it would be cheaper for them to make without a temperature sensor and a fan, right? That would be a safety hazard. Or, they could just limit the maximum output so that a fan would never be required but also not create a safety issue. So, from time to time a small fan might kick on. It's not loud. It sounds like a laptop fan when it does need to kick on. You'll only hear it when you're drawing a lot of power through the unit. I did not find it off-putting. Others might I guess based on some of the reviews here, but honestly it's no biggie.Very happy with my purchase here.

I took this convertor on a trip to Africa. It worked perfectly and even exceeded my expectation. I feel like I made a great investment by buying this device.

Horrible. I've had it on for less than an hour (new, out of the box) and it keeps restarting. Complete loss of power while it cycles back. Do not buy.
