Pros:

• This is a very innovative design. The charger is lightweight and is more organized than the conventional ones.
• You can really save a lot of time while charging to devices at a time. Not to mention that this is a fast charger

Cons:

• I believe 5000mAh battery isnt enough to cater two devices. It is just too small for one device, how much more for two devices
• This is the first time I encountered this kindnof charger. So I still have issues in terms of power circuit. This may be an issue of short circuit occurence
