This may just be my FAVORITE product ever purchased on Amazon! I love products that serve more than one purpose. The scale feature works perfectly so I never have to worry about my luggage exceeding the airline weight limits. (I tend to cut it close. lol) Then, once my bags are packed, I toss this into the small bag I'm taking on the plane. On long flights, it's easy to drain the battery on my phone while listening to music or surfing the web. This baby is always ready to recharge it for me. Even when I haven't plugged it in for a while, or think I have drained the battery, it still charges my phone. There is also a nice LED flashlight feature that may come in handy in a pinch. Of all of the luggage scales out there, this one is by far my favorite.
