It’s not clear what you are trying to say, but CC/CV charging is the standard way to charge Li-ion batteries, and the DPS supports this (modulo termination). There is nothing “old and outdated” about CC/CV charging. I suspect you have misunderstood something.
You might want to do some research on how a (good quality) hobby charger adjust the voltage and current when charging a lithium battery.
It is not “just send it x voltage and y current and wait until full”

My view is neither negative or positive. I have no excitement for it though.
The review link is not working.

If the final product is useful to him, then the cost is justified.
If it would not be useful to you then you are right, it would not be worth it to you
ImA4Wheelr knows me all too well. He zeroed in on that topic when he posted this:
He realizes that this build will cost me nothing other than the price of the DPS5015. The case is from an old battery charger and the power source, the yard tool battery, I already had and have other uses for it.
He knows that with all the stuff I am constantly buying, for example, Home Depot Deal Alerts & Discussion Thread I really gotta watch my spending.

Not everyone, e.g. I carry my tiny-cased DPS5015 in my jacket pocket and use it with whatever power supply happens to be convenient, which not only includes AC/DC SMPS, but also various batteries (laptop, vehicle, powertool, powerbank, etc). RD had a small case about twice the volume of mine but it seems they have sold out.
Btw, RD mentioned on youtube that he is trying his hand on a higher powered version of the buck+boost DPH unit. Hopefully he succeeds.
we have new case now , old case , we don’t produce this now

thank you for your support , about the input , in fact , it is easy to find switch power supply or second hand conmucation power supply, they are all cheap.
or you can use a battery to make a portable power supply.
I use DPS3005 to make a portable power supply.

That’s a cool take on the PS!
I also love how flexible the DPS is. If I don’t need high voltage or output for USB testing for example, I use a small battery pack to power it.
in fact , you can put the battery inside. it will be great, and you can add a charge circuit, you can see our work

When I first opened up this Ridgid dual bay charger and I saw this sweet power supply, it crossed my mind that I could possibly use it as is and connect 2 of the DPS5015’s. I did mention that I intended to check out that power supply, and while I am waiting for my shipment, I will do just that. I will post voltages and current capacities later.
Perhaps what I could do is use one half of the dual power supply and have both a plug in Bench supply AND a portable one.
I think it would be as simple as a DPDT switch on the input of the DPS5015 to make it work.
Of course it would all have to fit in the case and all.
I do know this, starting right now I will be scrounging around for another one of these Ridgid chargers.

I hope you didn’t misunderstand my last post.
What I was saying was that after I finish my portable supply using the DPS5015, I may order 2 more DPS5015’s to build another plug in supply if I can find another old Ridgid battery charger.
My AliExpress order# 83204400326397

I have this one already.
Is yours much different to this? I know yours has the front panel which looks real nice.
