Electronics and technology blog    /    Stores    /    AliExpress    /    Interesting products on AliExpress

The traditional 11.11 sale is coming up, so I decided to put together a bunch of links to products I came across over the year since the last sale. Some are products I bought myself or added to my cart but never got around to ordering, while others are simply things I thought might be useful or interesting.

Once upon a time—or, to be more precise, 5 years ago—I posted a big roundup of various interesting products. Time went by, and I updated it a little, but now it’s time for a complete refresh, so I decided to start a new thread “on this topic.” As always, I won’t use the tired old phrases “top 100 products” or “how did I ever live without this,” but I will say that you might find something useful here after all :)

I've been meaning to start this topic for a long time. I could have called it something like "Top 100 Best Products," but I don't want to write another cookie-cutter list, so it'll simply be called Popular and Useful Products. I'll be posting links here to various products that may interest electronics enthusiasts (mostly) and blog visitors in general. Some of the products will be ones I've tested myself; the only difference may be the seller.

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.

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.

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.

Those who regularly read my reviews know that I’ve already reviewed several electronic loads from Atorch. In each one, I’ve predicted (or suggested) what the next models might include. But less than six months later, the company has released a new model with the rather strange name CL24. In this preview, I’ll try to figure out what it’s all about.

This is somewhat of a promotional post, but in my opinion, if a manufacturer sells a product with honest specs, I don't see anything wrong with showcasing it. Especially since quite a few people bought these batteries after my previous reviews, and I don't recall anyone complaining about them. Plus, there's a sale on right now, with coupons and so on.

With the widespread use of various mobile devices—and, consequently, power supplies and power banks—that use a standard USB connector, an entire class of electronic loads designed to test them has emerged. In fact, these loads have a lot in common with regular electronic loads, but their specific applications mean they may have features that regular loads lack. At the same time, they may not be able to do everything their “big brothers” can.

It hasn’t even been a couple of months since RuiDeng released a complete adjustable power supply based on the RK6006 module, which I reviewed not long ago. But it turns out they didn’t stop there. More in the article.

I’ve already reviewed two electronic loads made by Atorch. I can’t say they were all that great, but I can’t say they were bad either. That said, I’ve noticed that each new version of their products gets better. While I wait for mine to arrive for review, I thought I’d put together a short preview.

Many of you probably remember that I’ve had just about every converter model from Riden, or RuiDeng, pass through my hands. To this day, I’m still not sure which name is correct. After the RD6012P came out, I’d check from time to time to see what was new, but unfortunately, nothing had changed; the hybrid 6012 was still their latest model. Then, just today, I spotted a new product, and I’d like to share the announcement with you.

It's been quite a while since I last wrote about Vapcell batteries, but I recently received a package from them with four samples. So today, here's part one: 21700 batteries rated at 5200mAh.

Today's roundup is about materials and tools for assembling battery packs, though I may add a few other things as well.

Another roundup of assorted products—some I just came across, others I ordered, sometimes more than once.

Another roundup of assorted products. Some were bought recently, while others caught my eye while browsing AliExpress. They might come in handy.

It's been a while since I posted a roundup, and there's another sale on AliExpress. Anyway, I didn't spend long looking around; I just decided to share links to products I've ordered recently, in case they might be useful to someone else too. These are all products I actually ordered, and I've already received some of them, so the sellers have been tested.
