AliExpress is having a sale right now, and I spotted a good price on the DL24MP load. People often ask me about it, but I haven't reviewed it yet, so I decided to kill two birds with one stone: share the good price, give it a quick review, and compare it with the DL24EW along the way.

Of course, cables like these are often better and cheaper to make yourself, but in this case I just couldn't resist the sale prices and ordered two sets right away :) In any case, I think the information will be useful.

While testing various electronic loads, I ran into a problem: I needed a high-power adjustable power supply—well, relatively high-power, of course :) I already have an adjustable supply based on an RD6024 converter, and everything would be fine, except it had only an 800 W power supply, while I needed at least 1200 W. So, during the November sale, I picked up a 1500 W unit for an upgrade.

I was sent this interesting little device. Well, calling it a device might be a bit generous; for the most part, it’s probably more of a display gadget. But it all depends on what you need it for, and for some tasks—especially the kind beginners in amateur radio tend to have—it’s perfectly adequate.

Those who regularly read my reviews know that I’ve already reviewed several electronic loads from Atorch. In each one, I’ve predicted (or suggested) what the next models might include. But less than six months later, the company has released a new model with the rather strange name CL24. In this preview, I’ll try to figure out what it’s all about.

I've been using thermal imaging cameras for a long time. My first one was a very basic model with a resolution of 60x60. I later replaced it with an HT-A2 with a resolution of 320x240, and today I'm reviewing a model with a resolution of 256x192. It might look like a downgrade, but is it really?

Almost a year after this model came out, I finally got my hands on one. It was inevitable—I enjoy tinkering with this kind of thing. There are already tons of reviews of this model, so I decided to look at it as a measuring instrument and, more simply, check its measurement accuracy.

An interesting little device has landed in my hands: a clamp meter with 1 mA resolution and Bluetooth connectivity. As usual, I’ll take a look, run some tests, take it apart, and share my conclusions.

A small addendum to my review of the Vapcell N40 batteries in the 18650 size, with a capacity of 4000 mAh. Since these batteries are quite unusual, I decided to test their self-discharge, and today I can share some results.

This is somewhat of a promotional post, but in my opinion, if a manufacturer sells a product with honest specs, I don't see anything wrong with showcasing it. Especially since quite a few people bought these batteries after my previous reviews, and I don't recall anyone complaining about them. Plus, there's a sale on right now, with coupons and so on.

With the widespread use of various mobile devices—and, consequently, power supplies and power banks—that use a standard USB connector, an entire class of electronic loads designed to test them has emerged. In fact, these loads have a lot in common with regular electronic loads, but their specific applications mean they may have features that regular loads lack. At the same time, they may not be able to do everything their “big brothers” can.

Some time ago, I announced a new product from RuiDeng: an enclosure with a power supply. The kit I ordered has finally arrived, and that’s what I want to tell you about today.

Last time I showed the lead-acid battery that “couldn’t cut it.” I said there would be a second part, so today I’ll tell you what I ended up having to do to get something that works.

Recently, one of my regular readers gave me a rather interesting converter, and I’m very grateful to him for it. Naturally, I decided to review it.

A small package arrived recently with four batteries inside. To be honest, I wasn't expecting it, but the batteries inside were an even bigger surprise.

This is the second product from Baseus sent in for review, and it's a car charger. The idea is interesting, and the specs are great, but "something went wrong," and we'll try to figure out exactly what.

Another product that was sent to me for review some time ago. It arrived at the end of February 2022 and had to be put on the back burner. As for the product itself, it's a three-port "charger" rated at 30 W.

I happened to notice that RuiDeng's store has a discount on the RK6006 converter, and thought it might be useful to share.
