250 Watt Travel Voltage Converter, 100V-220V Travel Voltage Converter for Curlers, Hair Straighteners, Chargers with 4 USB Charging Ports and 3 AC Plugs, Includes A, C, D, G, I, L Plugs (Black)

Had a very low wattage electric toothbrush and it charged just fine from A/C.

This voltage converter does what it says it does, within the (margin of error). It claims to to support an INPUT of 100 to 240 volts and OUTPUTs 100 to 120 volts at 250W max. So I thought I would put it to the test. I took it on my trip to Hong Kong where I brought several plug adapters so I can plug my stuff in but they don't convert voltage.I brought my multimeter to perform the tests. I tested the voltage before using the converter and I got 224 volts. I then tested the output of the converter and got 111.5 volts. Then I plugged in and turned on my Andis T-Outliners that are only rated for 110 volts. As soon as I turned on the liners, the voltage dropped to 99.3V, which is in the margin of error for the rated 100-120V after conversion.MOST portable electronics these days support 100 to 240 volts for charging and powering, so most people will NOT need a converter. Just look at your power brick to see what it supports. However, I learned the hard way that not all surge protectors support up to 240 volts and will need a converter. Based on my testing, this adapter does exactly what it says it does.I previously brought these same liners with me to Jamaica, which is SUPPOSED to have 120v power like the US, but in some places it's still 220 volts. It worked but made a horrible noise when I tried to use them. Basically the motor inside was spinning way too fast. Which can't be good for it. It worked just fine using this converter, even though the voltage dropped.So I would say, if you need to plug in a few SMALL electronics that NEED 100 to 120 volts, then this is a good converter for you. Based on the 250W limit, I don't believe this will work for a hair dryer as they generally pull over 1000W. It has 4 USB ports, but they are slow for today's standards so I wouldn't get them for this. If you just need the plug to be adapted, just buy the adapter for where you are going. You can even get a universal adapter that works for all the countries, but they are a bit bulkier.TLDR: This is a good inverter, that does what it says it does. Most people will be just fine with an adapter that doesn't convert voltage, but allows you to plug in your US plug since most devices accept 100 to 240 volts. Don't buy this for USB charging, although it does work, it would be slower than today's standard. Limit is 250W output so will only work for smaller electronics. Will NOT work for a hair dryer.

During my recent international travels, I depended on this travel adapter to keep my electronic devices charged across various destinations. It proved to be quite versatile, accommodating different socket types without any hassle and keeping my laptop powered up. However, an unexpected issue surfaced: my laptop began to give off small electric shocks when in use while connected to the adapter. Though the adapter was effective in its main function, the unintended electrification of my laptop's casing was both surprising and unsettling. Despite its overall usefulness, this shocking drawback has me thinking twice about its safety for future trips.

It has a solid feel and heft to it. I plugged it into US house 110 and the USB ports worked for charging, not fast or superfast. I won't be able to further test it until my Europe trip later this year.

First, the good: This is an excellent universal USB charging block that will work, as far as I can tell, anywhere in the world that has electrical outlets. It has various settings to extrude the different plug connector types used in various parts of the world, so it can be plugged in. On the other side, it has a variety of sockets corresponding to those plug connector types, as well as 2 USB-A and 3 USB-C charging ports - enough for even those most electronically addicted.I plugged it into a standard US outlet. The USB-A ports provide an OK 850 mA to charge my phone, and, the USB-C ports a much better 1200 mA. There's even a handy zippered case to protect the block from damage, and a couple of spare fuses.The UK prong configuration includes a third plastic stabilizing prong that serves no electrical purpose - normally it would be a ground, as with US-style three-prong outlets. That's fine if your UK outlet has this third hole, but as in the US, older ones may not, and this won't fit those even though no ground is electrically required. I suppose you could cut or snap off the useless third plastic prong to make it work, but that's not ideal.There is one odd quirk with the prongs for US usage - you twist them sideways to make them fit Australian outlets. That should work fine, just perhaps a long-term weakness.Unfortunately, the instructions and description warn multiple times that this adapter only adapts plugs, it does not adapt voltage. This means that the regular plug sockets, which cover pretty much all the standard possible connectors, won't actually work the way you expect them to. Most foreign locations which use different plug configurations, also have a different voltage, and you need to adapt between both for the adapter to be any use.I think this is likely a good and useful international power adapter for USB port powered charging devices. But I'd be very reluctant to use the sockets for non-USB devices, as I have no idea what the output voltage might end up being or if I might fry something. And, I'm not sure I'll bring my multimeter with me on my next foreign trip to find out for sure.Compared to other similar options, this device is a bit on the pricey side, so shop around. But, it does have 5 USB ports, more than most, and claims it can handle much more wattage, so if you have a lot of hungry USB decides this might be a good choice. Thus I'd give this a qualified recommendation for that purpose. I just wouldn't recommend plugging anything into it other than to the USB ports, unless you are 100% certain you know what you are doing as far as voltages.

This is a nice compact adapter, but I don't trust it as a voltage converter. There is conflicting information in the description and user manual that isn't very clear to me, so I'd rather not risk it. And I'm not sure why there is a 3 prong uk plug. In my experience, I have needed 2 prong, so thus, I would need an adapter for my adapter. All that said, I like the amount of plugs and overall design. As a travel adapter, I would use it often. Since I need a converter, I am going to find a different one that I have more confidence in for my upcoming trip.
