Really cool Outlet
. Great Outlet it’s built well has USB and C ports regular 110 ports as well. I think I got a special deal on it so it was a good value it would fit in your travel bag if you want to use it for that to plug in your phone or watch. Or any devices it’s really easy to use and it fits in a nice spot out of the way. And yes you could definitely use it for traveling and on the go.

Good buy.
Used it in hotel that had few outlets. This cord was long enough and work perfectly. It accommodated all electronic needs. I pack it in my suitcase everywhere I go.

Quality product
2 things I really like about these: 1) They are smaller than a power strip. 2) The 110v outlets are on separate faces, so wall-wart power supplies don’t interfere with other outlets.The USB-C chargers are a bonus. Very nice product.

Cord
Works great for what I needed, easy to carry in my bag, just wish it was 6 feet rather than 5 feet.

A good quality buy.
I ordered this to throw in my backpack with my laptop so I could set up shop for my Thesis writing whenever I had a chance. This fits perfectly and has a long enough cord to keep me off cold floors and away from the hustle and bustle of the world around when Iâm in the road, at a conference or in the boardroom. I love the multi ports they come in handy for my other devices and I have yet to experience any issues.

Great design and length
Iâm usually looking for a longer-length extension cord, but this length was perfect to put next to our couch for our grands when they visit. Design looks neater. Perfect for their phone/device charging as well as any regular plug-in. There is no extra gaudy cord.

Great search protector
This search protector is really nice but, it’s a big cube I thought for some reason it was going to be smaller but seems to work pretty good, very sturdy though
