Battery Charger with Magnetic Contacts

Battery Charger with Magnetic Contacts

First of all, I want to thank you for showing interest in my previous project of magnetic contacts , and also backer the work with like! Now I see that there is interest, and as promised, I will continue to develop this topic.

This time I want to present a small charger with the same magnetic contacts. Frankly, I like them myself. In principle, I do not do anything that I do not like myself...

Also, the previous publication generated relatively little interest in welding contacts with magnets. And they often asked the question: "why didn't I solder; and what could not be soldered, etc." ... I answer: you can solder, and this time I will tell and show in more detail how this is done ...

In order to solder the wire to the magnet, first of all, this operation must be performed quickly, since overheating of the magnet leads to a deterioration in the magnetic properties. Therefore, the soldering itself must be performed on a heat-absorbing surface of the object, which will quickly take away heat. I used a small vise on which I placed the magnets. I heat the tip of the soldering iron to 350 degrees Celsius, this allows you to heat up the surface of the magnet very quickly and the whole operation takes a minimum of time. And you also need a good flux and solder so that the tinning goes as quickly as possible. You will find both in the project link list. In general, I use this flux all the time and buy it in cans of 100 grams. And the solder is perhaps the best I've ever worked with. There are such solders that after them the soldering iron tip has to be restored. This is brief, in more detail in the video.

The basic parameters of the module can be read on the seller's page, and there are many reviews on YouTube.

Of course, if I had done this device not on camera, everything would have gone quickly and smoothly, and the whole process took half a night along with the editing of the same video. So if this topic is interesting,let me know with a like. When I see your interest - I have something to continue the topic, for example a mini powerbank with the same contacts, and besides, many more different modules can be used.
