Question: if I have dual voltage for my blow dryer and flat iron will this be safe to use in Ireland?
Document: I bought two of these. One for me and one for the other couple traveling with us. They were recommended to me by an expert traveler above the "cheapo" versions. I see why. Durable, fully functional and PURPLE :)! I like the fact that you get two outlets in one device. I charged my phone and my camera at the same time. I also used it with my dual voltage blow dryer and curling iron with no problems.
Quick warning is that anything that heats or has moving parts needs extra consideration when it comes to power conversions (hair dryers, flat irons, etc.) so you should buy dual voltage travel ones if possible! Then you just need only set the switch according to the power of your travel location. I used a dual voltage curling iron with this plug, too. For simple USA dual power devices, this plug adapter did the trick in Ireland
I purchased the Travel Adapter Plug for use on a recent trip to Ireland. It is a quality item, and worked at every hotel I visited. Being able to plug in 2 different items at the same time is a definite plus. Buyer should be aware that voltage in Ireland is 220 volts, and that the adapter does not reduce voltage to 110 volts. All of the items I used were dual voltage; 110-230 volts, so they worked fine.
The adapter worked great in England for computer, cell phone and curling iron. I believe you'll need an additional adapter if you are wanting to use a hair dryer.I agree with several others that it's important to get a higher quality adapter, especially for use with your computer.
Worked 100%  in Ireland and England for me. charged phones, iPad, hair dryer, straightener, and iron without difficulty. Brought 2 with me
I have owned many adapters for international travel and this is the best. I just got back from using it in Northern Ireland, the Republic of Ireland, Scotland and England and it was a joy to use. The dual plug is really handy because many older hotels have few power outlets, and I carry multiple chargers for cameras, cell phones, laptops. I really appreciate that this is grounded, making it especially useful if your device has a grounded three-pin plug (e.g. a laptop).
I used this in Scotland for 9 days. It worked very well with my curling iron which automatically adjusted to the voltage. In addition, I used it to charge my Motorola tablet. The tablet also adjusted to the change in voltage.
WONDERFUL LITTLE PLUG! it has two outlet plug ins, so you can have two things getting power at one time. be careful and make sure your appliances are dual voltage or else it will melt them! but this plug was a great size and very easy to just tuck into your purse!
I used this adaptor for various items, including a Kindle, MP-3 Player, hot rollers, hair dryer and iron and all worked perfectly! It appears to be well-made and yes, the color serves as a vivid reminder to pull it from the outlet when you're ready to go. I also appreciated the note with the adaptor explaining how it differs from a converter; where appropriate, I made sure to switch to 240v prior to our departure for Europe.
Ships FAST & works perfectly! You can even plug two things into it at the same time! Keep in mind, for hair dryers, you still need one that converts to 220. I brought along an extension cord with three plugs & was able to plug in all my charges for iPad, iPhone, etc, plus use my hair dryer! I love it!
Answer: Yes, I think so. If your device says 110/240 or something close to that, this adaptor will do the job. We did use it in Ireland. Also note, that all hotels we stayed in throughout United Kingdom provided hair dryers in each room, so you may not even need to take a blow dryer. We didn't and each hotel had one in the room.
