Electronics and technology blog    /    Materials for June 2023 year

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.

These are the third batch of transistors I've received. When I started testing them, I thought I'd give them a quick check and put together a short review, but things went completely differently from what I'd planned...

Along with the FDA59N30 transistors I recently showed, I ordered a couple of other types. Today I'm reviewing one of them: the relatively low-voltage HY3708.

This will be my last battery review for a while. I don't know when the next one will be, and today we're looking at 21700-size batteries from BAK.

At the beginning of March, I had three Tpcell product reviews: two types of batteries and a charger. I recently checked the product page and noticed that two more batteries had been added to the lineup. I decided to find out what they were like and tell you about them.

I recently reviewed some FDA59N30 transistors I bought on AliExpress. I mentioned then that I’d ordered a couple dozen more, and here they are.

Yes, batteries again, but this time from the popular Nkon store. In my opinion, these are the best batteries so far in terms of price and specs.

Yes, I’ve already reviewed these batteries, and to be honest, I didn’t really expect to see them in the package. But first, they’ve already been sent, and second, I have something to compare them with, so I’ll test them too. And yes, these are the last batteries from the six pairs I recently received.

Not long ago, I mentioned that some interesting batteries were coming, and now it’s time for what I think is the most interesting one: batteries with almost the highest capacity in the 21700 form factor.

Another interesting set of batteries, interesting above all for their high capacity.

About a month ago, I posted a preview of a new version of the electronic load from Atorch. I’d already reviewed a couple of their devices, and they’ve updated it a couple of times since then, but somehow I never got around to testing and reviewing it. Now I’ve got the latest version of their device, the DL24EW, in my hands.

Today's review will be relatively short, although I wouldn't say these batteries are uninteresting—quite the opposite, really. They just didn't involve any intrigue or mysteries.

As I wrote in my previous review, almost all the batteries I received have some feature that caught my interest. Here’s the second one I’m testing, and what caught my interest wasn’t so much its specs as the fact that there’s no information about it anywhere.

Recently, I unexpectedly received a new batch of batteries from my sponsors at Vapcell. At first, I expected a routine series of reviews, but things turned out to be much more interesting: all (or almost all) of the batteries have some unusual feature, and a few even left me stumped. But you can find out all about them in the review.

About a month and a half ago, I posted a preview of RuiDeng’s new adjustable converter, the RK6006. I finally got my hands on one recently, tested it, and today I’ll share my thoughts.

It's been quite a while since I last tested batteries. I needed some cells in the relatively uncommon 18350 size to repair a vape, so I bought some, tested them, and here are the results.
