As part of a promotional campaign, Fnirsi recently offered me a chance to review one of two devices, letting me choose between a measuring tweezer and a clamp meter. As it happens, the clamp meter caught my interest both in its own right and for a very practical use I had in mind. So today, I’m reviewing the DMC-100 clamp meter.

Sometimes, when looking at tool batteries, I wondered why no one had combined one with a power bank. Yes, I’d come across adapters that offered a similar feature, though only in one direction: discharging. But recently I saw something in the TPcell store that really caught my interest: a battery with a built-in power bank.

Back in the spring, I bought a pair of tweezers on sale (three items for next to nothing), tried them out, and ended up tossing them in my desk drawer. Now I’ve finally found a little time to tell you what they’re like, why I don’t use them, and how they compare with my main pair of tweezers, which I bought quite a while ago.

Not long ago, I spotted a new product from Atorch, got interested, contacted the manager, negotiated a discount (unfortunately, not a very big one), ordered it for review, received it, and now I’m sharing it with you.

A quick look at a handy little gadget. I bought a few to have on hand, and maybe I’ll include one with one of the new loads.

As I mentioned recently, I needed to build a powerful charger for one of my custom electronic loads. I’ve already shown you the converter, so now it’s time for the power supply. I’ve reviewed a similar SMPS before, which makes this all the more interesting—we’ll compare them.

A quick look at an inexpensive adjustable 60 V, 20 A voltage converter. It’s not exactly great, but I wouldn’t say it’s terrible either. Overall, you get what you pay for.

Na-ion batteries based on a relatively new chemistry (though that depends on how you look at it) have finally made their way to me. I bought them specifically for a review and to satisfy my own curiosity, and now I can share the results of some tests with you. I think you'll find them interesting.

Some time ago, I published a roundup of various products and included a nice-looking multimeter that can measure inductance. I also decided to buy one to review and test it, thinking it might be useful. Well, I received it yesterday, tested it, and decided to write a review while it was still fresh in my mind.

While putting together a list of products for the 11.11 sale, I spotted some interesting gadgets: bumpers for Riden power supplies. Yes, they’re highly specialized and somewhat controversial, but this time, along with the work-related orders, I wanted to buy something “just for fun”—and I think I made the right call.

I hadn't kept up with the latest additions to the range of converters on AliExpress for a while, but then the app showed me something new. I got curious, started looking into it, and it turned out there were some interesting new products. And as a bonus, here's a few other little things that might come in handy too.

We all know that sellers often pull a fast one during sales, but sometimes there are genuine discounts. Since I know the prices of some products pretty well, I can tell right away whether a discount is real. Anyway, if you’ve been looking for a DL24MP electronic load at a good price, this is the place to go.

Yesterday, a package with Fnirsi's new battery impedance tester finally arrived. I spent most of today exploring its features, running a few tests, and writing this review. I'll say right away: I have a lot of work on at the moment and not much time, so I'll keep this relatively brief.

I was asked to share information about a sale on Fnirsi’s new milliohm meter. It looks like an interesting little device, so I thought it might be useful to you.

A couple of months ago, one of my readers sent me a RuiDeng power supply to test. Well, it’s sold under that brand, although as far as I understand, it has nothing to do with the company itself. He sent it to me because he’d seen my review of the same power supply, bought from the same store, but it turns out quite a few changes have been made since then.

Recently I announced a new product from RuiDeng: the RD6030 converter, with an output current of up to 30 A. It’s definitely an interesting new model, so I ordered one right away. Today I’m ready to take a closer look at it.

Quite unexpectedly, RuiDeng has released a new converter model. I really wasn’t expecting this from them after the RD6024 came out. Here’s a quick look at what they’re offering.

At last, I’ve found the time and opportunity to review a relatively new model of electronic load from Atorch. Is it any good, and what has changed? Let’s find out.
