Wow this interesting. Looks like a macbook charger.
Pros:

• I like how it available both for Android and iOS. For people with multiple devices this would be great. Just one cord for all.
• Ease of use. Plugging in to charge made so simple.

Cons:

• Not sure if it really necessary to buy it as a secondary charger. Not really solving a big problem. But an interesting idea. I would consider it if I had to a new charger.
