Another power supply for my collection of Mean Wells, this one from the fairly well-known LRS series, rated at 350 W. Inspection, schematic, tests, conclusions—the usual :)

With Intel releasing newer and newer processor models, I was a little surprised to find that mini PCs are still being made with older chips, such as the X5-Z8500. But since I’ve reviewed quite a few computers based on Atom processors, I decided to take a look and see whether anything had changed since my previous review.

Today I’m reviewing a rather unusual power supply. Though, to be more precise, the power supply itself isn’t so much unusual as relatively rare “around here,” partly because of its price. One of my regular readers sent it to add to my collection, and I’d like to thank him for that.

When I started writing this review, I spent a while wondering whether to classify this device as an SSD or a flash drive. In the end, I decided it was more like an external SSD than a flash drive. You'll find out why in the review, which also includes a look at the device and some testing.

The new product from Rui Deng has finally made its way to me: an adjustable voltage converter for building a bench power supply. I originally planned a more extensive review, but one of the suppliers let me down badly and shipped the power supply much later than I’d hoped, so I had to split the review into two parts: a main part and a follow-up. The follow-up will also answer questions that came up after reading the main part.

I came across a couple of coupons for new users and thought they might be useful.

Although there’s very little time left before the sale ends, I got an email from RDtech—or RuiDeng, whichever you prefer—today. It included links to discounted products, so I decided to share them almost as soon as I got the email.

The third type of battery sent to me by one of my blog’s regular readers. I’d originally planned a fairly routine review, since what new is there to say about such well-known batteries as the LG HG2? But, quite unexpectedly, an ordinary review of ordinary batteries turned into an interesting experiment. As always, more after the jump.

The second battery—or rather, batteries—sent to me by one of my regular readers, whom I’d like to thank. There’s nothing particularly remarkable about them, except for the large number of models that are barely distinguishable from one another.

I've reviewed a lot of batteries, including high-capacity ones, but one interesting "fellow" had never been tested. Thanks to one of my regular readers, I now have it in my hands, and today I'll be taking a look at the Sanyo NCR18650GA.

Some time ago, the ambitious Beelink GT-King Pro TV box was unveiled. Essentially, it’s an updated version of the Beelink GT1-K, and today I’ll take a look at this new model. As usual, I’ll inspect it, take it apart, run some tests, and share my conclusions.

The latest model of adjustable power supply—or, more precisely, a converter for building one—has appeared in the well-known RD official store. This post is something of a preview, since I don't have one in hand yet. But I'll have a question about that at the end of the post.

I came across a faulty power supply and decided to jot down a note about repairing it, and while I was at it, answer a few questions people ask me, using a real example, so to speak.

This is the second part of the saga, “a battery tester for a friend,” and today I’ll be talking about changing the output voltage of the power supplies and connecting them in series.

After reviewing so many batteries, I decided to bring them all together in one big article. No unnecessary information here—just inspections, tests, comparisons, and brief comments on any noteworthy features observed during testing. Warning: this page uses a lot of data!

As the “repair” project gradually winds down, I’m slowly finding time to get back to my other projects. I’ve started with the multichannel tester for lithium battery packs, which I first wrote about last year. There will be several stages, but the first is the most challenging one: the power module.
