    Product Description

    An excellent solution for power hungry chargers.
    The A20S can supply a constant 20A at two 12v ports, making it perfect for chargers using alot of power to charge big packs fast, or you can hook up 2 smaller chargers to charge up to 5 or 6S packs each.
    The unit also displays the draw current and it will automatically turn off if the draw current is over 20A which makes your charger and even the whole setup more safe. Even if you dont charge at high rates, having a solid power supply like this will ensure the charger is supplied with a good constant current, helping it to balance cells and operate better.

    This PSU has a selectable mains input switch and will suit 100-240v 50-60Hz home power points.

    Spec.
    Input: 100~240v
    Output: 12v @ 20A

    Purchased unit and within 24 hours it stopped working. Fuse was not blown but display read nothing. Took apart the unit and something really burned up. See pic https://www.dropbox.com/s/c5o0i2wmmcnkusi/burnout.jpg. Wish it had worked longer. If anyone can help me identify the burnt out part maybe I can fix it.

    This specification is wrong. A power supply does not produce constant current to a charger, it produces constant volts. There is no spec for the change of voltage with load and it is not displayed. I'll get the Propeak power supply. I haven't bought this item, but I am a qualified engineer unlike whoever wrote the spec.

    I used mine about 12 times before it started to smoke and then just quit. I have a 20 amp charger, and it would only ever charge at 16 Amps before it tripped the automatic cut out, so I never charged it above 10 Amps so the product would be sure to last a good while. It did not, and customer service is a joke. No working phone number that I know of, and live chat never gets through for me. The wagon wheel spins for hours and nothing happens, and it takes more than a week to get a half assed response from an agent off of the hobby king support center. Cheap products at cheap prices, but God help you if you need support, at least that's my experience, so far
