A one of a kind USB Power Bank. Great work @htliao on your hunt.
Now for my personal review below:

Pros :

• You will never be having a problem with power supply on your gadgets when you are traveling since it has enough capacity to support 60W-100W and has 2 USB ports wherein you can do charging simultaneously two devices.
• This storage has a much bigger storage capacity with 20,100 mAh and what's make it ahead of other power banks is that it can be fully charge up to 3 hours only with such a huge power storage capacity.
• It has features that fully protects the battery life of your devices during charging process makes it less worry when you charge them.
• This power bank supports also file transfers aside from its primary usage. It does supports also fast charging making it less than for gadgets to be fully charge. A good way to do charging when you are always in a hurry especially when you are on travel.

Cons :

• Since it is electronics still there are possibility that it will get damage so make sure always that this power bank is secured on liquid and static areas.
• It has only two USB ports which i think should have at least four slots to make it much better and reliable power bank.
