Small solar cell high amperage

  1. Mar 27, 2012 #1
    dear experts

    i saw a solar charger the size of an iphone that has high amperage rating of over 1000mA to 2000mA.

    Based on the solar cell size i estimate it to produce at most 250mA at around 5 volts.

    I like to know how the high amperageis derived.

    is it using super capacitors ?
    if so , is it charging up the sc and them discharging to battery at high amperage like 1000mA?

    Thanks for reading.

    best regards

    It may be slowly charging some cells inside its box. You can quickly charge your phone battery by connecting to these cells.
