  • The small size and compactness comes handy for carrying the power bank anywhere.
  • The three interchangeable connectors widen the use of the product for charging different USB based products.
  • Great customer service.


  • The confinement of the components to a small volume in the power pack may result in heat production on long time usage, and the small size of the power bank and aluminum casing could restrict effective heat dissipation.
