    Can build variable power supply relatively easy for low voltage & current. Check radios shack projects for more details.

    I like how it 'looks' and I like the functions, but I am always weary when the price seems to good.
    I don't have experience with that name-brand.

    Ok and what kind of a multimeter do you have if you owe one?

    I've got a basic little Fluke meter. (Can't remember the model)
    It does not have the extra functions. I can do Resistance, Voltage, and Current.

    So its orobably similar to my brothers/mine UNI-T ut33d
    (http://www.uni-trend.com/en/product/2014_0729_811.html)

    Years ago, I saw a "Power Pump" in a CB magazine and the plans to make one. It was a 'plug-in' that converted 110 VAC to 12-13 VDC with a rock solid output. There was an option to see just how many amps was being used when the CB was being used. The specific voltage could be controlled by a specific resistor. The whole thing fit inside a 3" x 3" x 4" box. I built one and used a mobile CB, in the house as my base station. It could also have been used as a 12V battery charger. Slight research, may find the answer to your project.

    looks respectable, for $30 if you get several years out of it ( you may get much longer) before you have to replace it ... it's a great deal, has a good range of test modes :)

    those things are shocking compared to FLUKE which are the industry standard. My FLUKE is over 30 yrs old and still chugging along

    I only made the UNI-T comments out of personal experience
    the previous company I worked for the boss bought 5 of them one for each of the workshop and on-road techs
    none of them lasted more than 2 years, 2 of them died within 6 months !!

    one would hope their quality has improved over the last few years ... but regardless, I wont touch that brand again ;)
