    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.

    A small noise is present, if 2 or more accumulators are inserted, even if PB is turned off.

    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.

    Pros:
    - functionality, as a 18650 battery charger and also a power bank - charging using microusb (included) or lightning cable - display with charge level and output current
    Cons:
    - size (but probably couldn't be smaller ;)) - noise from device, even when powered off

    Pros:
    Good priceQuite good qualityYou can use different cells
    Cons:
    It's a bit noisy - it's whistling while chargingWhen 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.
