    My powerbank arrived in minimal packaging (which i always like)
    Once opened you are met with a rather good looking device in brushed metal with blue accents at each end

    As per instruction the first thing you should do is to fully charge the unit, lets face it you do not want to run out of power when you are out and about
    Charging can take a while as this is a large capacity powerbank

    I have tested the device on a xperia z ultra which is a massive phone, also on a standard sized phone like the htc one

    Initial charge rates are about 600 plus mah for the majority of the charge at least until around the 90% rate

    I have found that with the size of my phone that some chargers will not work however no such problem here, so basically if it charges mine it should charge yours

    Now the benefit here is that you can cherge two devices at once which is a boon when camping or some other adventurous outdoor pursuit

    My son likes it that much he keeps trying to pinch it from me, so there you are it has son approval too

    So how would i rate this out of 10 well it has to be at least a 9 it is a must have for keeping you going
