ISELECTOR Voltage Converter 220V to 110V, Travel Converter US to Europe with 4 USB Ports, 3 AC Sockets 4-in-1 Adapter Suitable for UK/AU/US/EU

My wife and I used this on a trip to Spain and Ghana. Loved that we could plug in multiple devices to the converter so only had to take one for the both of us. Were able to charge 2 phones, 2 headlamps, and a battery back up overnight on the one unit. The supplied adapters worked for the 2 different types of plug-ins that we encountered. And it is a Voltage Converter. Many of the devices out there only change the outlet and don't convert from 220V to 110V. This one does. Only negatives are that there is not a USB-C plug in but so had to bring the USB-C blocks for plug in rather than a direct plug in like it has for the USB-A(standard) and it is a bit bulkier than some so if you only need to charge one device, might be more than you want to pack.

Versatile in many countries, compact, and many outlets. Great value. This is a power voltage converter, not a rechargeable battery.

Due to weight & space restrictions on my luggage, I opted out of carrying the cord & power strip with additional charging ports -- I regretted that decision and should have left something else behind. I used the small adapter at every hotel I stayed at in Peru. In Peru, there were multiple outlet types and the converter worked with every outlet -- had to find and use the hidden adapter. I would definitely travel with the whole kit so that I could charge multiple items (camera battery, AirPods, iPhone, etc.). I have only used the converter for one trip, but I would recommend it. It never let me down and was essential for my trip.

This has turned out to be perfect for my trip to Europe. It turns out that not only are the outlets different in Europe, but there are very few of them and thus far, no USB outlets to use. The outlets in Britain and France are completely different from each other too. The fact that this converter has a 4 ft cord and 3 outlets plus 4 USB slots is great. Green light on the box tells you it’s on, as you often need to turn room outlets on and off with a switch here.

We were a group of 5 traveling to Australia and used the converter daily for a month and were totally amazed to be able to charge our phones, watch and even computers through this small converter... it worked as a harm.... totally saved us ease and functionality..... Excellent!

Bought 2 different voltage converters, the first one did not work with most of the devices that we tried to connect to it. This converter is very reliable and worked with everything we needed to connect to it, especially my CPAP machine. Excellent device (this was in the Phillipines). Threw the one converter away and buying another one of these for next trip to Europe.

We visit countries that have 220 and can blow computers and cellphones. I always use a converter indwell again this year on out trips. This one was the best I ever bought. get one plug for the country and the plug this in and you have multiple USB and US plugs.

This power converter was really helpful during my overseas travel. During my two week get away, I had no problem with this portable device until about 10 days in. After about two hours of use, a red light flashes on and a "whir" sound kicks in within the plastic encasement. Not sure if it was because of a voltage spike, but I quickly turned it off, waited a few seconds and put it on again. The sound had stopped. Unfortunately, this would repeat itself about three more times throughout that day. On other occasions it might happen once in a day until I returned from my trip. Maybe the adapter saved my electronics from frying. Who knows? I give this a 4 out of 5 stars.
