Congratulations to all who read / writeNew Year. I wish you health and well! Well, as for the charging power supply, then everything is simple: I mock him electrically and mechanically, I’ll take a picture of it + some text.
The packaging did its job and the blocks came to me unscathed. Each is a Soviet plug without grounding contact with the counterpart. On the side faces of which there are arched notches for the convenience of grip and switching.
And at the end - USB ports (2.1A and 1A from left to right, respectively) with a signal LED between them. Each port is signed with a counter-relief. This is not to say that the inscription is easy to read, after all, the text matches the background, however, with a certain knack, each port can be identified.
On one side at the base of the plug there is a nameplate indicating the model (S3) and technical specifications. I got a little twisted, but still a typo of DV 5V? 2.1A smiled.
The power supply (excluding plug contacts) has a relatively small size - 62x45x22 mm. So, most likely, it will not become an obstacle to the use of neighboring outlets.
When power is supplied, the hellish LED lights up in blue, which, by the way, does not react to the load, i.e. just indicates the presence of voltage at the input.
Well, photos of how things are going with voltage and I’ll hide it under the spoilers. The logic of measurements in each of them will remain unchanged - this is work without load, as well as in the mode of 1 and 2 amps.

A certain discrepancy in the output currents is, of course, evident. Although this is partly offset by a deliberately high voltage and the “loss” of power is not so large.
For a real test, I recharged my onda v891w tablet. Charging was 5.12V? 0.61A
As the tablet’s batteryrecharged by more than 500mAh, the characteristics of the output current did not change, and the outer surface of the unit was not hotter than ordinary electrical equipment under voltage, overheating, and even more so there was no smell / smoke.
Parts of the body are simply glued together. And although the design is very strong, but collapsible, which means it is maintainable.
The board is double-sided, in the case it is held on rails. The assembly of parts is electrically reliable, but untidy. I do not understand anything in circuitry, so I will leave the following photos without comment.
The block case has not yet been glued after assembly. So if anyone needs more detailed photos - write.
Uncompressed photo boards are available at reference
The results. Briefly:
+ compact size
+ two ports
+ in work does not overheat
+ reliable installation (both inside and outside)
± approximately corresponds to the declared characteristics
± very bright LED
± indication only for power
± the body is a glossy gloss. Fans of purity will be difficult
- typo on the nameplate
