[NSRCA-discussion] Curmudgeon's Rant

[John Ferrell]

Pricey is when you buy a piece of equipment that don't work. 

This supply is probably overkill. I bought it especially to power a ham radio transciever. It is only rated at 20 Amps but a SSB or CW transciever presents a very erratic load.

  A bit pricey for charging receiver packs, ain't it?

  FWIW, I smoked the very first one I had on the 4th or 5th use. I didn't over load it. Something was wrong, but they promptly replaced it with a new one that's been a trooper ever since.
  With the cigarette lighter type jack on the front it makes a nice device for powering all sorts of 12V devices. I like the ability to adjust the voltage and the meters too. It's a great device for $200.

    I have been using the MFJ-4245MV to run my Ham Radio Transciever for about 5 years now. It is solid!

      I've use this 45 amp unit from MFJ for the past two years.
      http://www.mfjenterprises.com/products.php?prodid=MFJ-4245MV
      I've been very happy with it.

      My next purchase will be a Rig Runner to use with it.

      This will let me tidy up things when running all my chargers.
      I like running several chargers at once, because lets me get all my charging done in a reasonable time.

Ya I have a bunch of them, the ones I have wont handle 1 10s pack.

They all claim 25A as well but none of them will actually output it for 
any length of time without significant voltage drop (which only drives 
up the required input current).

    Is this a hypothetical question, or do you have a link to the said

      It's real.

    Pardon the rant of a curmudgeon of the subject of power supplies for
    electrics. As the son of a mother who was born in Scotland, I am
    always looking for value. I often see products being bought and used
    because a person or group with "credentials" uses them. As a group,
    we are a bunch of lemmings and whatever the anointed individual or
    group uses, we buy and use. Logic regarding value doesn't seem to
    enter the discussion. For example, a current "must have" for the
    electric-powered Pattern airplane guys is an Iota power supply. Will
    someone please tell me what this very fine power supply will do that
    a switching computer power supply from Geeks.com, with a 12 volt, 25
    amp output and costing less than $20, won't do?

    I could go on regarding motors, ESCs, chargers and batteries, but
    I'll save those for other rants.
