As a frequent traveler, I have struggled with bulky adapters that constantly fall out of sockets (image shows one of the adapters that I currently own against the DOACE Voltage Converter). This travel converter has been a game-changer! It’s compact, lightweight, and easy to pack, making it perfect for travel.I like the idea of the converter-adapter combo, which covers all my destinations without needing multiple devices. Plugging in my devices is effortless, and they work seamlessly without any issues.Overall, this voltage converter is a reliable travel essential, offering both convenience and peace of mind. Highly recommended for hassle-free international travel!

TL;DR:I have done a lot of research and HIGHLY recommend the DOACE 350W Voltage Converter, sold on Amazon. It is a voltage converter that will ALWAYS output ~120V. I have been testing a lot of other cube-type adapters/converters, and even other converters that look like this one.None of the others have been consistent or have output a safe voltage in my opinion, and those others were all returned back to Amazon. Also, the cord on this device is European but it does come with 4 adapter plugs and a carry pouch!TESTING:I used a Fluke 115 TRMS meter for measurement testing. All testing was done here in the USA with a selectable AC bench power supply. The power supply was 120V 60Hz input and could output 200V, 220V, 230V, or 240V AC in either 50Hz or 60Hz at all voltages mentioned.My testing of this device was consistently 118V output regardless of the input voltage (tested with 120V USA Mains power from the wall, as well as 200V, 220V, 230V, & 240V inputs from the selectable power supply).The DOACE 350W Voltage Converter will ALSO convert frequency. My testing was consistently 60.1Hz output regardless of the input frequency (tested with 50Hz & 60Hz inputs).As advertised, this device can be used with 100V to 240V 50Hz or 60Hz input and always outputs ~120V 60Hz. (I have not yet tested with 100V (Japan) input yet - hopefully I can update this review later once I have a different bench power supply.)NOTE ON LOAD:Load is listed as 350W max on the device (which I have NOT tested loads yet either). This device should be fine for travel with small devices like electric toothbrushes, beard trimmers, etc. but make sure you know how much load (Watts) your electrical device will draw BEFORE you leave for vacation. **This will likely NOT power a hair dryer or curling iron/hair straightener.**>>DOACE 350W Voltage Converter, Ai 220V to 110V Converter and 50Hz to 60Hz Transformer, Power Converter Adapter Combo US to AU, UK, European Travel Plug Adapter for Hair Straightener Laptop Cell PhoneLINK: out of 5 Stars

This is great to charge all my devices when I’m traveling to different countries. It comes with different plug outlets for different countries outlets. It is easy to take on flights and great for countries with electricity with high voltage. Highly recommend for those traveling internationally.

I’ve been using it now for several weeks during an overseas trip and it’s the best I’ve bought. It has both USB-A and USB-C sockets and 3 regular plugs for your devices. Works great.
