Not long ago, I posted a review of my new compact soldering station, and afterward someone recommended replacing the handle with something more comfortable. I found one of the fairly well-known options, ordered it, gave it a try, and here are my thoughts :)

Not long ago, one of my regular readers suggested in the comments that I review an unusual power supply. It caught my interest, so I thought, why not? It certainly stands out from the crowd of common power supplies.

BAK batteries have appeared at the well-known Nkon store, and I've already been asked several times to review batteries from this manufacturer. Well, as it happened, I had a few of them on hand.

Continuing our discussion of multi-component batteries, today I’m reviewing another model with a different form factor and noticeably higher capacity.

A couple of months ago, I published a review of a drill/driver and mentioned that I had originally ordered it as a brushless model. But, as sometimes happens, "something went wrong," and I ended up with a model with a conventional motor. Some time later, I decided to try my luck again, and it looks like I got lucky. Inspection, teardown, a few tests, and conclusions.

Another power supply someone sent me a link to, and one that I think could be interesting, especially for use in T12 soldering stations.

Over the years, battery manufacturers have come up with an enormous number of different form factors, yet they still manage to surprise us with something new. It seems like only recently that 21700 and 20700 sizes "went mainstream," and things appeared to have settled down. But then I got my hands on some cells that are not only a different size—26800—but are also described as multicomponent. Well, let's test them, heat them up, freeze them, and see what they're all about.

It's been quite a while since I last reviewed a power supply—one of those "feeders" that power all sorts of devices that need less than mains voltage but more than a battery can provide. So, at the suggestion of one of my regular readers, I ordered several models to test. Today I'll be looking at the first one.

The story behind this order is very simple: I spotted an interesting, inexpensive drill/driver and thought it might be worth a look. But, as sometimes happens, "something went wrong". Still, in reality, things turned out not so badly, but even so...

This is my third review of an active balancer and my second review of a capacitor-based one, also known as a capacitive balancer. Last time, I focused more on how it performs, but said almost nothing about how it works. Today, I’ll make up for that omission.

I got this battery mostly just out of curiosity for the review, though that doesn't rule out using it for its intended purpose. But, as often happens with products in certain categories, "something went wrong". Still, it's best to find out all about it in the review.

A year ago, I reviewed the LRS-350-24 power supply. Today, here's a brief look at a model from the same series, but with a 48 V output. Since these power supplies differ essentially only in output voltage and current, this review will be short, but I hope it will still be useful.

I recently bought a couple of types of silicone-insulated wire, in 8 and 12 AWG. I hadn't planned to write about them, but I liked the wire so much that I decided to put together a short review after all.

One of the readers sent me a link to a deal that I think is quite interesting price-wise.

Information about a new model of adjustable converter, the RD6018 from RuiDeng, has appeared online. I did a brief comparison and decided to share what I found.

I was recently looking for something on AliExpress, but got a bit carried away and started browsing all sorts of interesting products. Here are a few I’d like to show you today—maybe you’ll find them useful.

I came across an interesting soldering iron—or, more precisely, one model available in two versions.

I found a few coupons, possibly even useful ones, for several products
