Hong Kong hosts the Hong Kong Electronics Fair every spring and autumn. In scale, it is comparable to Germany’s IFA and even the US Consumer Electronics Show. In September, the exhibition takes place alongside electronicAsia, a trade fair for information technology and communications. Both events are organized by the Hong Kong Trade Development Council (HKTDC) and MMI Asia Pte Ltd.

This is my third power supply review, and this time it’s a 240 W, 12 V model. It’s very similar to the previous one: low-profile, budget-friendly, and another invitation to play roulette. Still, it’s best to read the review to find out all about it, roulette included.

These batteries are high-current models, but they’re also budget-friendly, with a capacity of just 1500 mAh and a lower price than higher-capacity cells like the VTC5, HE4, and so on. Unfortunately, they’re no longer available for sale, although this may only be temporary. I think you may be able to find them in other stores, too.

Hello everyone! Today I’m sharing my thoughts on using my very first TWS earbud—yes, an earbud, not a pair. It’s one that I’ve really enjoyed using.

The second power supply sent by Banggood for review, and accordingly more powerful than the previous one. The only thing they probably have in common is that both power supplies are low-profile. As always, the review goes into more detail, with an inspection, teardown, tests, and of course, conclusions..

One of the readers tipped me off about some pretty good prices on useful little items, as well as a couple of popular multimeters. Thought they might come in handy for someone. As more useful items turn up, they may be added to this post.

Another battery in the high-current category, with a rated continuous discharge current of 20 A. It is essentially a competitor to the well-known Murata VTC5, although it falls slightly behind in terms of load performance. Still, it's best to check out the full review, which includes tests and a comparison chart.

I don't think I'm far off the mark if I say that many people who use multimeters have had to buy probes for one sooner or later. Sometimes it's to replace old ones, sometimes to improve performance, and sometimes to make measurements more convenient. I wanted to make my main UT181A a little more convenient to use too, so today I'm reviewing a set of probes and tips.

Not long ago, I reviewed some fake batteries, including what was supposedly a genuine Samsung ICR18650-22P, but it had an old production date and arrived almost completely discharged. Today I'm reviewing new, genuine batteries of the same type, so there will be comparisons as well as measurements.

Not long ago, Banggood sent me several different power supplies. They differ in almost every way: voltage, power, and manufacturer. I decided to test them and publish reviews in order of increasing power, so today I'm reviewing the first one. This power supply isn't very powerful, and it's compact, but I hope it's interesting. Of course, it's best to read the full review for all the details.

Not long ago, Beelink released another new product: a compact computer with a Core i3 processor. Though, in my opinion, it’s hard to call a fifth-generation processor new, since it was developed quite a while ago. Still, this computer turned out to be pretty good in its own way. But you can read all about it in the review, which covers the inspection, teardown, tests, and conclusions, along with a summary table.

Not long ago, I ordered an interesting little gadget from AliExpress. I didn’t have any specific use in mind; I just bought it because it was inexpensive and had some unusual features. But as usual, you’re better off reading all about it in the review. I hope you find it interesting.

Another battery review, but this time we'll see what's going on "on the dark side"—that is, among Chinese battery manufacturers and rewrappers. In this case, we're looking at Liitokala, a company known not only for its batteries and chargers, but also for how deftly it can turn one battery into another simply by changing the wrapper :)

The last battery from my test order at nkon, and I saved it for "dessert" because it’s not only a high-current battery, but also comes in the relatively new 21700 form factor, with a capacity of 4000 mAh. What’s more, today I’ll be testing it at currents above 30 A.

Hello everyone! I’d like to share my thoughts on a gaming mouse from Xiaomi that has left me with mixed feelings. I’ve been using it since April this year.

Well, friends, judging by the claimed capacity, these could be considered record-breakers in the 18650 form factor. I mean, 3600 mAh—is that really what they deliver? A review, tests, and conclusions, as usual.

Looking for an alternative to the well-known Panasonic 18650B and Samsung 35E, I decided to see how LG, another well-known manufacturer, was doing with high-capacity batteries. So I ordered two types, and today I’ll be talking about the first one.

So, I’m done reviewing batteries I already knew pretty well, and I’m moving on to models I’ve never tested before. I’ll start with the relatively new VTC5D series batteries. I hope this will be useful.
