Perfect for a small desk

This power strip fits perfectly on the corner of my small home office desk. The fact that you can rest your phone on the built in shelf while it charges is very convenient. This is much better than the power strips that sit on the floor.


Diseo inteligente y carga r¡pida

Me encant una gran compra, es muy frecuente que no puedas ocupar todos los contactos porque se estorban fue una manera muy inteligente de disear este contactony feliz porque carga muy r¡pido los USB.

Bigger than I thought. My own fault for not actually measuring. It works exactly as advertised.

Easy to access, Fits in a small space I do wish the phone caddy was in front of the USB ports and not a plug. Thats the only design flaw



It is awesome the cord could be a little longer but I dont mind I have an extension cord is perfect for where Im doing studying and I need to have everything plugged in at the same time if you are a student or somebody who uses a lot of electronics in one place this is the product for you
