    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    It's a very small and cheap charger, perfect for travels and for all those old Li-Ion cells in the back of the drawer missing the original charger.
    Charges from USB power, standard PC port is enough (500mA).
    Automatic polarity detection.

    Cons:

    Only charges cells to around 4.15V.
    Charger pins seems a bit fragile.
    Some cells are hard to get connected correctly, specially if the terminals is placed on the edge of the cell.
    Works best with a USB extension cable.

    OtherThoughts:

    It charges with up to 500mA at Vbat=3V, and gradually drops down to 100mA at Vbat=4.15V before stopping.

    Bottomline:

    A nice handy charger, but be careful when connecting it to the cells.
