A weekly roundup of things I came across on AliExpress this week that might be useful to other readers too.

The new RD6018 adjustable converter is now available from the official RuiDeng store

Not long ago, one of my readers got in touch and offered to let me test some batteries I hadn't handled before. But in this case, we're not talking about a different chemistry—that part is familiar enough—but about the form factor and capacity. As usual, though, it's best to read the review for all the details.

Not long ago, I published a review of a step-down converter module rated for up to 20 A. As I mentioned then, though, it was already the second one I’d ordered from AliExpress. Today I’m reviewing the one I received about a year ago instead, with my first order.

Another weekly roundup of useful and interesting products from AliExpress.

A micro-, or perhaps even nano-review of little gadgets for radio amateurs, designed simply to make your DIY devices look a bit neater.

Information about a new model of adjustable converter, the RD6018 from RuiDeng, has appeared online. I did a brief comparison and decided to share what I found.

In the spring, I ran a capacity test on a pair of batteries and mentioned that they had arrived along with three LG HG2 cells. I finally found the time to post a short review of those three batteries.

I’ve reviewed an LRS-series power supply before, but it was a higher-power model with active cooling. This time, I got my hands on its little “brother,” so today I’ll introduce it to you. Inspection, tests, conclusions—as usual.

I decided to get an inexpensive switch for home use—mainly for configuring various PoE Ethernet devices—and figured I’d take the opportunity to see what PowerLink’s budget PoE switch is like.

Another Friday (or maybe Saturday) roundup of interesting products I came across on AliExpress.

No, friends, this isn't actually a coupon or a sale. I was just browsing AliExpress and happened to stumble across a model of adjustable converter I hadn't seen before.

When I ordered a multichannel battery tester, I also picked up ten thermal switches from the same store, ZKEtech. I needed them to control the cooling fans in high-power electronic loads and power supplies. I meant to review them right away, but then forgot about it, so today I decided to make up for that oversight.

Since I occasionally test camera batteries, when I saw these special alligator clips for connecting to them on Taobao, I decided to buy a couple for myself. But as it turned out, it wasn't that simple.

While putting together one of my Taobao orders, I came across some interesting converter boards. After reading the customer reviews, I decided to pick up a few for myself. Since someone else might come across them too, I thought I’d put together a short review.

In today's installment of my VapCell battery review, there won't be a variety of form factors: the whole review is devoted to one size, probably the most popular one, 18650. Even so, I think it'll still be useful.

I needed a powerful step-down voltage converter for one of my projects, so I decided to give it a quick test before putting it to use. A quick look, some tests, and my conclusions.

Today I'm writing about how a friend of mine ordered batteries for Makita on AliExpress, and how it all turned out.
