I have a carry on luggage, but for some reason, it seems like it is a lot smaller than other carry on luggages I have a seen. I want a full sized carry because carry ons are already small and limited, I don't want one that is limiting me even more! The brand SwissTech has been around forever and is known to be reliable plus I have had a large luggage piece from them that I used for over 15 years before it finally broke and I think 15 years is quite a long time for a luggage that I have used many times. With the Swiss Tech Executive 20", 4-Wheel Spinner Luggage, I want to start off with talking about the feature that is my favorite part of the luggage, but was a bit confusing on how to use it when I first saw it. The USB port. It is a little confusing because there's no explanation on how to use it, so I hope I can help a little. The USB wire inside the luggage is for you to plug in a battery pack (Not included with the luggage.) and how you charge your devices is that you need another USB wire that you will connect to a USB port located on the outside of the luggage. Because the port site is black, it is camouflaged with the luggage and it took me a few minutes to find it, so I posted a photo that will hopefully help you find it easier. I have seen luggages with this feature, but is my first time owning one and I am super excited to have one. I tested it out and it works well! Yes, at the airport, there are plenty of places to charge devices, but what is more convenient than charging it through your luggage where ever and when ever you decide to, plus, you do not have to fight other people over charging stations. The wheels roll very smoothly. I like that the handle has multi-level telescoping so that different people in my family can use it. I was able to pack everything I need for a 3 day trip. It is spacious with lots of pockets, which I love! Makes organizing so much easier! On top of all this, there is a 2 inch zip around expansion feature which I can use if I need a little more room, or just zip it up if I don't need it. The size is perfect for a carry on, of course everyone wants something bigger, but keep in mind, any bigger will risk not being able to fit it in the overhead bins of the aircraft, so to me, it is perfect.
