    Working as advertised. Control pots are a bit finicky. Just the way they are. Higher end pots have no residual variation when changing direction on the screw. These pots, when going ccw to lower the output voltage, actually go up a bit before starting to go back down. When going cw to increase the output voltage, it is steady as a rock. So, for anyone else buying one, start from a lower output & then increase & you should be fine. These are obviously meant to be "set it & forget it". O.K.

    I just hope short circuit current limiting is fast enough to not blow main supply fuse. Sorry not tested yet. Beware because some dc-dc's just shut down all together or have current surge. I do see soft start switch with hope I don't have to add external circuit to avert above problem.

    This seller sent out 4 of these units and was quick to respond to my needs to replace or refund for the 2 D.O.A.s that arrived. It happens to us all and we don't like it happening to us but, S..T happens. I was grateful to know that he was understanding enough to respond to this issue befalling this multiple order of items. All of the other items checked out fine. I will be returning to this seller for future orders needing to be filled.

    You will need an adjustable to set your current and voltage limits at the same time. It's $9 it works, could it have been made better yes. But for intended purpose of driving a 60 rechargeable work light.... Perfect!!!

  • Works well, good price

    Works in my application, though haven't tried maxing out its power output. Only gripe is would be better if had larger terminal posts.

  • Does what it says

    I got this for a particular project, it works perfect for what I'm using for. I have stress tested it using 24v feed at 7-10 amps, it kept the voltage right where I adjusted it to be (12.5). I can' judge longevity since I've only had it a few weeks.

    It works well though stepping up for the output regulation at 300w isn’t steady enough.
