Key Power 230-Watt Step Down 220V to 110V Voltage Converter

This was perfect! Easy to use and had more than enough slots for all the devices that I needed to charge. I hope it will last. Design was great and the travel pouch made it easy to carry and pull out of my carry on bag for quick use at the various oversees airports I was at during my trip.

I used this voltage power converter on a 4 week trip to Europe. I used it in Iceland, Denmark and Germany. It worked great for all of our 110v US electronics. It powered up a curling iron in the outlet port and at the same time, it also charged 2 mobile phones, an ipad, and a power brick via the USB ports. It charged everything quickly and we didn't have to worry about devices overcharging or things overheating. The red/green light indicator is great so you know whether your device is charging or powering up correctly. I've also used this on a cruise ship. It's great because all cruise lines forbid surge protectors on board. Most power strips these days have built in surge protectors whether you want it or not. We were able to use this converter as a big power strip on the ship! The best part is that most cruise ship cabins have 2 US 110v outlets and 2 European 220v outlets. We were able to plug this into the European outlet which gave us more US 110v outlets for all our devices. YAY! There is a small fan inside the converter that runs when it's in use. It was so quiet that it just faded into the background like white noise. If nothing is being charged, you simple unplug the converter or turn the power switch to the off position. The entire unit comes in a small mesh bag to keep the unit, plugs, and power cord organized. It found it a bit heavy to lug around in a carry on bag for a day of airline travel, so I put it in my checked bag. UPDATE: 5 years after purchase and 2 years of not being used due to the pandemic, this device stopped working properly. The fan started making a high pitched sound that was so loud you couldn’t carry on a conversation.

EDIT: Seller refunded me after seeing my review. I appreciate the time they took to email me and ask more specifics about how the product didn't meet my expectations. We just returned from a 2 week trip to New Zealand. I specifically bought this product as it advertised being able to use in NZ and being able to convert the voltage so I could use my curling iron. Thought it was able to be used for electronics such as hearing aid charger and phone chargers, it did NOT work for my curling iron. It continually tripped the converter switch. The one time I got it going for a few sections, it heated so quickly I thought I'd either break the curler, the voltage converter, or damage the lodge's electrical system so I quickly turned it off and did not use the curler for the entire trip (it was a bad hair day for 2 weeks!). Too late to return of course. I didn't mind the price if it has worked, but there were cheaper adapters that would have worked fine without the converter (in fact, i also had two of those for by the bedsides and they did work fine). Disappointed.

Was able to charge 4 phones at once. Default plug without adapter worked in EU and on plane. Sadly it did not provide enough power for my hair straightener is only reason I am giving it only 4 stars. From the pictures it looked like that should work, but didn't.

Versatile. Used on a trip to Portugal with no issues. Great for those with a CPAP machine

Tried to use it on a trip to the UK and was very disappointed. A common ground is not used and if you plug more than 2 items into the unit it shuts down. For the price I would expect more.

This is a brilliant, easy to use, nicely package product that works great. The step down is great.

This power converter is great! It comes with every type of plug you could possibly need, plus a nice carrying bag to keep everything together. While it's plugged in, it gives you 3 outlets, 3 USB-A ports, and 1 USB-C port, which is more connectivity than many other similar converters offer. It only has one dim LED on the front to indicate whether it's on, and it's bright enough to tell if it's working but not enough to be distracting in a dark room. It seems really well-built overall, with a solid heft to it. If you plan to take it in a carry-on though, be aware that it might add some unwanted weight to a bag. It's also on the bigger side, nothing unmanageable but it's thick and can take up a fair bit of room. I'd compare it to the size of a paperback book, if you only pack the cable and the specific adapters you'll need. It's also completely silent - I know that some of the cheaper converters have a tendency to let out a quiet whine, but I stuck my ear right next to it and couldn't hear a thing while it was converting UK 220v power. I purchased this specific one since it was a bit more expensive and better reviewed than some of the cheaper options, since I intend to take it on multiple international trips. While there's currently only one week-long trip abroad under its belt, I hope that it'll last a while and continue to work on future trips. Overall I highly recommend this converter, and if you're on the fence about saving a few bucks to get a cheaper one, I would just spring for the added quality of this one.

EXCELENTE PRODUCTO me sirvio en mi viaje a Europa, es una maravilla ya que pude usar sin problema mi plancha CHI digital 410°F, conectaba 3 celulares iphone y un power bank definitivamente vale la pena comprarlo es de gran utilidad y adicional tiene enchufes por lo que si no se conectaba el cargador para iphone lo podiamos conectar directo de la LUz con el enchufe ya que ese no necesitaba transformador de energia, la idea principal fue para utilizar con confianza mi plancha de cabello!! estuve Feliz todo el viaje con mi convertidor de energia.
