Overall, a nice and compact power bank with good capacity that can give a full charge to big devices (September 29, 2017)

Simple, easy to use, and compact. The power bank has a really good build quality, fits in the pocket, and and does not feel cheap in the hand without any flimsiness. 3400mah enough for big devices such as Galaxy Note 8 for a single charge (0 to 100%) and will probably fully charge the regular iPhone 2 times. Also, it charges fast enough even though it is 1A which I though would be much slower compared to 2A chargers that I always use.

Packaging:

• The power bank came in a branded box
• There was documentation (manual/warranty) .
• There was a Micro USB charging cable.

Pros:

• compact, light, and easy to use.
• 3400mAh in a compact form factor
• Charges fast enough even though it is 1A
• Solid build quality without any flimsiness or creaking noises.

Cons:

• Only 1A output instead of 2A. (might not be a con due to small capacity)

Comments and/or Suggestions:

• Definitely cannot charge a Tesla.

Bottom line:

Overall, a nice and compact power bank with good capacity that can give a full charge to big devices (Galaxy Note 8)
