        Pros:
        This power bank is small and good looking. Comes with a very nice package. The price is very good for such an item. You can put inside up to 4 18650 batteries, so the real capacity could be over 12 000mAh. This 18650 batteries could be easy replaced, could be charged inside too. This TOMO power bank has display showing capacity level for each battery.
        Cons:
        I put inside 4 batteries of about 2000mA each and I charged my mobile from 20% to 100%. My phone acu is about 4000 mAh. I think I could easily charge it from 0% twice. The display show voltage and each batterry level. The best thing is that I can put new 18650 battery when those inside is discharged.

        Pros:
        Pretended to be the universal device 2 in 1 - charger and power bank. Has an additional lightning charging input socket.
        Cons:
        Very slow as a charger. Doesn\'t use all available energy from inserted batteries (stops to use an inserted battery when it has 3.26-3.28V). Has a big self discharging current. Will be significantly discharged within couple months.

        quite good stuff
        Pros:
        Good price
        Quite good quality
        You can use different cells

        Cons:
        It\'s a bit noisy - it\'s whistling while charging
        When you\'ve got about 20% level of power you cannot charge devices. Tomo t4 is switching off after few minutes. I think it\'s because of cell protection.
        It\'s better to have cells with the same capacity and the same level of power.
