Pros:

• All-In-One, please imagine how a wallet can have a variety of interesting functions. In addition to functioning as a normal wallet, it has a function as a powerbank.
• The design is very elegant and strong.
• 3,000 mAh, enough for my Xiaomi Charging device :)

Cons:

• Its Perfect.

My Thought:

• One for all and all in one place. WOW, the concept is interesting. In fact you no longer need powerbank. LOL.

Perfect and Recommended
