Sure Mex, PM me your email address, and I'll send you some non compressed photos that will be in the 8 to 10Mb range. Hope you can open such size files and can zoom in. Lots of the photos I post here are very cropped and adjusted for best contrast, then reduced in size, saved as a smaller file and then Photobucket further compresses them when uploaded there.
I find it is easier to take a good photo then blow it up on my laptop and zoom in, rather than try and use a magnifying glass.
I am curious how different this clone is internally than the Meanwell or Megawatt.
So hard to say what goes on in China. It seems that Everything designed on this side of the PAcific, and then fabricated over there, basically has its design stolen, cheapened further and then comes back to compete with the original designer who could not viably produce the product here for the multitudes of reasons that exist.
Is it like the johnson controls battery. One made for wally world and sold cheap, one made for interstate and much pricier. Are they made the same, or is the more expensive battery made to a different standard? The WW battery owner needs to believe the WW battery is just as good as the higher dollar option, the interstate owner refusing to believe the cheaper battery is exactly the same internally, just in a different color case. An internet forum provides a medium by which both sides try to get others to agree thus validating their feelings, or working them up into a tizzy if it goes against what they need to believe.
With this Meanwell, megawatt and Etopzinger clone, we can remove six screws, and have the answer. IS anybody going to open up their Meanwell/Megawatt and compare internal components to what I will post in this thread?
But how much variability exists from day to day production and will any answer be definitive if we are comparing a MW made 3 years ago and a clone make 4 months ago?
But who knows when either was made, where, what parts were taken from the assembly bin, and whether the assembler had some good nookie the night before, or was nagged to infuriation by some bickering chinese princess and then bicycled to work in a smoggy rainstorm and started inhaling soldering fumes first thing in the morning wishing for a quick end to a $lave wage existence.
For 23$, I was not concerned about breaking the seal, but I could have easily kept it intact. I tested it, it performed beyond its rating, beyond my expectations, then I opened it up to have a look inside. Poof goes the warranty, wait a minute, there is no warranty! There was no instructions, nothing on the box, just a box within a padded box, no documentation of any kind, just the knowledge that if it was DOA, Amazon would take it back easily.
This Etopzinger supplier has at least 3 different listings for what appears to be the same product on Amazon, all in the 23 to 26 dollar range, and the reviews range from it was a DOA POS or failed in 2 days to it has been going strong for 2 years continuously and is a wonderful product. One of these listings shows that the openings for the fan are much larger than on my model. They've been out for a while, there are obviously variations and some changes since they were first cloned.
Within seconds of ordering mine there was a new review by somebody whose clone had parts rattling inside right out of the box. Made poorly or kicked to the doorstep by some irritated delivery person who was annoyed to infuriation by some self declared American princess the night before?
Too many variables to say.
I get a bit annoyed when people attribute motivations to my actions.
I wanted the options of choosing my charging voltage, and these power supplies are the only thing out there which allows me to do that. This product does what I want. Perhaps I got lucky with this cheapo clone, perhaps it will fail tomorrow. Do I want to believe it is made just as well as the Meanwell, sure. Do i believe it? No, but perhaps the only difference is the graphics over the screws.
To make this product Ideal for me, a finger turn pot, to make it easier dial in desired voltage is, desirable. I could likely never 'need' it. I already own a better fan I can swap into/onto this, and if this fan keeps the unit cooler, and makes it quieter, which is highly desirable to me, perhaps it will last longer than it would otherwise. I've no issues modifying something like a fan location or opening to reduce restriction. I know from many other products that the fan location, orientation and design are all compromises and that way better options exist that were not economically viable for the manufacturer.
For years I've been educating myself on charging sources, trying to figure out which overpriced converter was the best compromise for my batteries, and this MW clone came along and allows me the option of no compromise for a fraction of the price. I'm impressed with it and hope it lasts. Keeping it cooler is the best way i know how to achieve this, but it only gets warm making 15 or more amps. Not sure how often I'll be asking more from it than that.
Only if the converter makers would allow easy ABSV changes, durations and a programmable float voltage would I think their products are worth the asking prices, but their one size fits all charging algorithm is insulting. Their marketing and sometimes their fan boys are insulting too.
