Not long ago, I posted a review of triple frames for assembling battery packs, and now I’ve finally received the single frames. There’s not much new to say, so this review will be minimalist.

I often see people measuring the capacity of smartphone batteries, power banks, and the like with USB testers in forum comments and reviews. I once tried to explain why measuring them this way makes no sense, but today I’ll approach it from another angle and test the testers themselves.

Last fall, I posted a review of the interesting Vorke V1 mini PC. It’s a pretty good machine: fast, doesn’t overheat, and lets you install a hard drive. Not long ago, an updated version with an Apollo Lake J3455 processor appeared on the market. I got interested, ordered one, and wrote a review. Of course, the review includes a look at the device, tests, a teardown, and a comparison with the previous version.

Back in winter, I posted a review of 64x32-pixel RGB LED panels, which gave me a 192x32-pixel scrolling display. But, as I found out once again, the more you have, the more you want, so I decided to double the resolution—not by making it longer, but by making it taller. Anyway, if you're interested in this topic, come on in.

Special offer: Vernee Thor-E smartphone for $99.99. See the description for details.

Today I have a short review of a compact espresso maker. It’s an interesting little device, and in some situations it can even be useful. I’ll tell you all about it in the review, so if you’re curious, read on.

Just recently, I posted a couple of reviews of chargers, but as it happened, another one accidentally came my way. Unfortunately, it’s also a 12.6 V charger (for a 3S lithium battery pack), but I decided the review might be useful because of its low price. Alas, it’s not quite what I’d hoped for, but more on that in the review.

Another review of another small charger for 3S (12.6 V) battery packs. Not long ago, I published a review of the 3 A version; today, it’s a simpler 1 A model. Unfortunately, things didn’t go as planned, but I won’t get ahead of myself—the details are in the review.

This review is barely even a micro-review; it's more of a nano-review, it's so short. Still, I thought it might be useful to someone.

Another mini-review of various useful little things. This time, it’s holders for one or two 18650 batteries.

Today I have not just a mini review, but a micro review. It’s about some very inexpensive but useful “helpers” for anyone who often uses battery packs made from 18500, 18650, and similar cells.

I decided to make a video version of my review of this unusual multimeter-oscilloscope, since some things are easier to show than explain in writing.

Some time ago, I read a review of this multimeter, and recently I got exactly the same one. Since it was sent to me for testing, I had to write about it, so I’ll simply try to describe the device in my own words. Maybe someone will find something new here.

Not long ago, I published a review of the iLife A4 vacuum cleaner. I also mentioned then that it was already an outdated model that had been sent to me by mistake, since the A4S had replaced it. This time, though, I'm reviewing a genuinely new model, albeit one in a slightly higher class: the iLife A6.

Not long ago, I was asked to write a little review of an IRULU product. I decided to give it a try out of curiosity. A quick heads-up: this is a very basic tablet, but I’ll test it just like all the others. And of course, there’ll be a teardown.

Almost exactly a year ago, I published a review of the debut model from a manufacturer that was still unknown at the time, Vernee. You can say a lot and criticize its shortcomings, but in any case, the Thor model they released first turned out not to be so bad after all, and one of these “firstborns” has been under my watch for more than a year now. So today I’ll tell you about the next phone in the Thor lineup, show it, and compare it with the previous model, sometimes “face to face.” And, of course, there’ll be the obligatory teardown.

I was offered the chance to try out a product that was unusual for me: a robot vacuum. Since I really like all kinds of automated devices, I couldn't turn it down, so here you are reading this review. A vacuum cleaner is certainly useful, but in this case I was more interested in it as an automated device. Still, as always, although the main focus today will be taking it apart.

Today's mini-review is about four different camera batteries. They look different, but their specifications are remarkably similar. Still, it's better to see for yourself.
