It's good design with 4 cords, convenient. But very slow to charge conpare to my other charger. Using other charger takes way faster to get full charged. This one is really "just incase" needed items. Not to recommend to busy businessman. Wish it was Charger code for Base. It can save someone else without code but can not charge itself if you don't have your charger code. So not so convenient. I know there's another model has it's own outlet built-in...but I already ordered this one when I found the other one. So after while I'm using this, I will recommend the other one with own outlet to charge itself...
