    There probably is no LED to show it's charged. I wouldn't be leaving this power bank charging unattended...

    Dealz have 1,200MAh ones for €1.50 / £1 with lights.
    Red for charging flashing / steady , Blue for discharge.

    Cheap and cheerful, but not enough capacity to fully charge your phone.

    I find them perfect for powering Arduino projects :)
    Good for powering any other devices low external power supply requirements as well.


    Has anyone seen one with an adjustable voltage level - Ive seen them a while back that can output 3v to 19v with a range of plugs - but dont seem available anymore.

    Just hack one...add a boost regulator module.

    Here's one I made earlier. Hacked inspection light (4.5V alkaline) and 5v fan. Making a rechargeable ultra-bright (over-driven) head torch. Complete with fan for cooling either the current limiting resistor or yerself and a range extender.

    Cool devices but marketing w@nk epitomised; I wouldn't need one most of the time if I could buy a phone with an adequately sized battery for my needs. Seems slim is more of a priority than longevity in that department.
    They're not a bank of anything they are a cell and a charging/driver circuit.
    1,200mAh is 1.2Ah.
    Sounds larger by abuse of SI units.

    My car does 200, 000, 000mm an hour. :rolleyes:
