Full disclosure &#8211; it was sent to free for this review.  That said, I&#8217;m transparent about my views on things and don&#8217;t sugarcoat.  The below review is my first impression of this unit doing some basic validation of it&#8217;s functions. In the coming months I&#8217;ll drop back in and update as I get more experience with this PS.  The review is broken into 2 parts:  1) Showing voltage \/ current features with a LED strip, Digital MultiMeter and my high precision CurrentRanger low current measurement tool.  2) A quick teardown with a look at the guts of the unit &#8211; because I like to take things apart!    <\/p>\n\n\n\n<p>In summary,  for $70CAD, it&#8217;s a suitable power supply that provides accurate voltage and current. However, it does suffer from an issue related to current limiting at low values (see video).  What I haven&#8217;t yet checked is if it has this same issue at higher current ranges (i.e. &gt; 1 Amp).  If you want to pick one up, click the link at the top (coupon in product listing).
