Plug Adaptor England, UK, Hong Kong 2-In-1 Universal Type G - 4 Pack Travel Adapter - United Kingdom, Ireland, Great Britian, Scotland, London, Dublin

For nine bucks this is a no-brainer purchase. The Type G UK set is sturdy and well-made and worked perfectly to connect our US devices while traveling in the Republic of Ireland for eight days. We stayed at a different hotel or B&B every night so having this set of four adapters gave me the peace of mind that I could plug in all our devices no matter what the outlet situation was at each place. I chose the white set over black for better visibility and therefore less likely to be left behind when packing up. We seldom needed more than two adapters at any stop (see my power strip tip below), but did use all four at one place. The extra socket on the top is a great bonus and was very handy at one of our stops where the the adapter was in a tight spot sandwiched between the wall outlet and the bed mattress.Here's another neat trick about these adapters: If there are no open outlets in your room, because one of the socket options on the front is the same UK type as what you are plugging into, you can insert an adapter between the wall outlet and whatever device is already plugged in, giving you access to at least the one 2-prong US-style outlet on top. The UK socket opening also means you can nest these together for packing if you prefer.I have read on some reviews for these UK outlet adapters that they are hard to push in. It seemed to me that the spring tension in UK outlets is stiffer than what we are used to here in the US. Don't worry, just wiggle the adapter and keep pushing, it'll go in all the way.Travel tip -- Power strip and extension cord:My wife and I traveled with these adapters plus a low-profile 6-outlet power strip with a 2-foot cord (bought at Big Lots for $4, UL certified -- their SKU 250007845, http://www.biglots.com/p/6-outlet-power-strip) and one of those common lamp extension cords with the molded 3-way socket head on the end (also cheap at Big Lots). This gave us plenty of US-style outlets to recharge two phones, two camera batteries in bulky chargers, a laptop, and power the Bluetooth speaker that we use with a white noise app on my phone. The 3-prong grounded plug on the power strip plugs into the socket on the front of the adapter; the lamp cord can plug into either the front or the bonus port on top, or even the power strip if necessary (although the fire marshal wouldn't like that!). Besides providing additional outlets, the extension cord allowed us to place the white noise speaker where needed in the room at night, and let my wife use her hair dryer in front of the most convenient mirror in the morning. It seems Irish bathrooms aren't equipped with standard wall outlets -- this was true even in a modern Dublin hotel room. I keep a lamp cord in my carry on bag when traveling anyway -- often comes in handy to let you plug in to a distant outlet at a business meeting or the airport, or share an outlet with another traveler. The power strip was especially useful at one B&B that had NO outlets in the room other than the one for the TV which was high up on the wall.To reiterate other reviewers, most any modern electronics power supply is designed to work at either the US voltage of 110 or the European standard of 220 volts, so just get these plug adapters and you're good to go. Just check the voltage range on your device labels to be certain. Anything with a motor and/or heating element, like a hair dryer, will need to be one that has a dual-voltage switch. Flip the switch while you're packing to leave in case you forget when you get overseas!

Note that these are NOT converters that allow you to adjust international electrical current to lower USA levels; they are adapters that correct for the fact that plugs have different shapes in different countries. If your appliance isn't rated for the higher international voltage level, then you're going to have a serious problem no matter what adapter you buy. (Many newer appliances and electronics have dual voltage capacity--check the label.)During vacation in the United Kingdom (mostly Scotland), we used these for a variety of purposes from powering our laptop and a hair dryer to recharging Kindles and camera batteries overnight, and they performed well. Because we took all four adapters with us, I didn't need to plug in two things at one time, but I did use both the grounded and ungrounded receptacles with appropriate appliance types and they were both fine.I initially thought that the receptacles didn't fit the plugs on some appliances, but they loosened up just fine with a bit of use. Just push firmly and make sure that the plug is completely in the adapter.Don't let the low price fool you--these adapters worked just fine.

First let me say that some of the negative reviews I see here are not about this Type C adapter, they are for the Type G. I find no problem with inserting a US two prong plug into either outlet on one of these plugs. Many vendors confuse the Type C with the Type F, but this vendor has them correctly labeled. Note that a Type C plug will fit a Type F outlet, but not vice versa because the Type F pins are slightly larger. Also, the top side outlet on the adapter has polarity like US type A outlets, but the front side does not have polarity. It will take the neutral blade on either side. It is nice that two Type A plugs can share one of these adapters. The front side will also take a Type G or a Type B plug. As always, passive plug adapters do not change voltage or AC frequency.

I live between the two countries. I have dozens of these.I am always careful about giving out this advice - but if you read your plug It will say input voltage. It usually gives a range. if it is a US device, you can plug into the UK if it says 240 (or 250 V) is listed and 50hz is also listed. If you do not see do not attempt to plug in a device directly it will break. Start with your laptop. Most laptops can handle both the US voltages. It will save you from converting from 240V down to 120V

These worked great in England and Scotland. Our phone chargers (phones did not work over there), tablet pc, hearing aid charger, and CPAP breathing device all had chargers that worked on 110 AND 220 volts, so these adapters handeled them fine. Each adapter can hold TWO 110 plugs at a time, one in the face, and one on the top -- so, it all depends on the shape of your wall-wart whether you can plug in two devices at once. -- We also carried a regular 110 volt extension cord, that we only needed to use once on the trip to get the power where we needed it in the room.These don't change the voltage, just the plug configuration. We never needed to change the voltage on our trip, although we did not take a curling iron, or night light -- which would have needed the lower voltage.
