        TOMO S4 - Very good power bank
        Pros:
        This power bank is compact and quality feels good. The lid closes very good and tight, so it won´t come off accidentally. The display is very informative, and shows all the information needed. Comes with a short cable, but it´s not really a problem since most of us have multiple cables laying around.
        Cons:
        None
