Some time ago, I posted a long list of interesting products for radio amateurs. At the time, I also mentioned that I planned to put together a similar list of products I had already bought, so I could share a few thoughts about the products and sellers, even if only briefly.

This is already the third review of RuiDeng products that I’ve posted, but there are actually quite a few reviews of their products out there, so today I’ll try to add a little to the previous ones—especially since this converter is interesting in its own right. As always, I’ll take a look at it, run some tests, cover a little theory, and share my conclusions.

Another batch of holders for 18650 batteries arrived recently, so I decided to put together a short review in case it comes in handy for someone. I've reviewed similar holders several times before, so this one is more of a follow-up to the previous reviews.

I’ve already posted a review of a very similar device once before—the title was almost the same, too. This time, though, the little meter is a bit cheaper, and its quality is definitely no worse than the previous one. So, here’s a quick review of a useful little gadget for electronics hobbyists.

Power banks are pretty rare subjects in my reviews. Somehow, I hardly ever use them in everyday life, but when I was offered the chance to review one, I decided not to turn it down. As usual, this review covers the exterior, teardown, tests, and conclusions.

I sometimes order small meters for battery packs, and I finally got around to testing them and writing a mini-review. A look at the device, a few tests, and some conclusions. I hope you find it useful.

I ordered this meter quite a while ago from a different store, but after browsing AliExpress I found a listing for a device that looks exactly the same. Since I'm almost certain they all come from the same basement large factory, here's a link to another store.

I've had this display lying around for quite a while, but I've only just gotten around to writing a review. I probably won't have much that's new to say, since this type of display is so common that it's hard to find a radio hobbyist who hasn't heard of it. The only difference from the popular 1602 and 2004 models is that this one has 16 characters across four lines.

Not long ago, I posted a review of a somewhat unusual electronic cigarette from Wismec, and mentioned that I’d ordered some atomizers for it. I liked a particular type of heating element, and I also found out that they’re hard to find in local stores, so I decided to order a few as spares from AliExpress. Anyway, here’s a short review with plenty of photos.

For some reason, there are very few reviews of power supplies like this. That’s understandable: buyers are usually more interested in high-power models than in little units rated at just 3 W. But compact models are sometimes exactly what you need for various low-power devices, especially when they’re highly reliable. Today I’m taking a look at just such a power supply, made by Hi-Link.

I already reviewed a small voltmeter about three years ago, and now another similar little gadget has landed in my hands. The previous one was more expensive, but it had a separate measurement input and could measure up to 99.9 V. This one is much simpler, but I figured these little meters might still be useful to someone.

For a few reasons, I needed an mSATA SSD. I first looked at local stores, then at stores on AliExpress. I came across various brands, but noticed that many sellers offered drives from a brand I hadn't heard of before: Zheino. There were quite a lot of them, and the prices were pretty reasonable. I found a seller with a large number of sales, bought one, received it, and decided to share it with everyone. An inspection, some tests, and a few conclusions.

I've already seen many reviews of this company's measuring instruments, so mine will be more of an addendum and another look at Sndway's products. I haven't come across a review of this particular model, though, and it has a few distinctive features. As usual, I'll take a look at the device, take it apart, run a few tests, compare it with another instrument, and share my conclusions.

Today on my workbench I have an adjustable voltage converter with an output voltage of up to 50 V and a current of up to 20 A. As far as I know, this is the most powerful converter in RuiDeng's product lineup. What's more, its specifications are very similar to those of the ZXY-6020, which I reviewed earlier and will be comparing it with today. While I'm at it, I'd like to say a big thank-you to one of my regular readers, without whom this review probably wouldn't have happened.

Not long ago, I was asked to buy a number of batteries for some radios. It was a pretty straightforward job: I found a suitable listing on AliExpress, placed an order, and a while later picked them up at the post office. But is everything really as good as it seems? Today’s review is a “micro” one; I’ll try to keep it short and stick to the facts.

A brief review of NCR18650B batteries with the LiitoKala logo, bought on AliExpress. In appearance and specifications, these batteries are very similar to the well-known Panasonic NCR18650B, but cost a little less. As usual, the review includes an inspection and thorough testing.

Not long ago, I posted a review of a relatively expensive 8-megapixel camera. Today I'm reviewing a somewhat simpler model, both in resolution and features. Its key advantages are its 4 MP resolution, low price, and well-known manufacturer. As always, read on for the rest of the review.

I've reviewed and tested various batteries, from camera batteries to cylindrical cells in all sorts of sizes, but this is the first time I've had 21700 batteries in my hands. Technically, they're ordinary batteries, just a little larger, but I was still curious to find out what they can do.
