Quick review of the Wsken Lite 2 Micro USB magnetic cable

Loose micro USB connector casing in a cheaptablet, and got the idea to buy a magnetic cable, so as not to bring the situation to repair. I read reviews, reviews and the choice fell on Wsken Lite 2. In short - the cable is suitable, it does not heat up much, you can charge it with 1A current. Overview, resistance measurement and comparison of it with a conventional Ugreen cable under the cat.

Additional Information



Bought for blood $ 4.43, now costs more expensive - $ 4.99, but the price is lower than mine - I saw $ 4.37 a couple of days ago. The product arrived in less than a month, the seller issued a track of the type ZAnnnnnnnnHK, which is tracked only in China and then immediately at the destination post office. It was packed in the usual yellow Chinese bag with a pimply film inside. Mail on the way could not damage anything (however, there is nothing special to break).
Inside an unremarkable bag of thick paper.

Rear sticker with those. characteristics and anti-counterfeit code under the washable ribbon. The code must be entered on the site www.wsken.com for authentication. But at the time of writing the review, the verification form did not work - when clicking Submit, nothing happened ...

We are tearing the bag. Inside the cable and some plastic stuff. Removable adapter is magnetic to cable. The bag turned out to be functional by the way - inside it is laminated with polyethylene, there is a zip-lok.

The cable length of one meter, in a fabric braid, is not particularly rigid, but the shape in which it was twisted, is well remembered. On the cable there is a removable sticky organizer.

The green plastic thing turned out to be a device for pulling the removable magnetic adapter from the USB socket. Very convenient, because Pulling the adapter with your fingers is not so easy if the socket is tight.

The length of the adapter is 8.5mm, the part that is inserted into the connector is 5.5mm deep. It is magnetized to the cable in only one correct position.

It is visible that not all contacts of the USB connectorinvolved - namely, ID (Mode Detect) "hangs in the air." This contact is responsible for OTG, so there is no need for it. Immediately, I note that data transfer with this cable works successfully.

The pins on the cable side are spring loaded. They are much thicker than needles in previous products of the same company.

On one side of the connector there is a dim white LED that shines always when the cable is connected to the power supply. In the dark, not blind.

Here is the review hero on the culprit of the purchase:

The USB connector is not very well located on the rounded edge of the tablet, because of this, the hole is skewed and a gap appears:

On the other hand, everything is fine.

The connector was already thoroughly razboltan, and I had tobend the connector casing slightly so that it is more tight. After this operation, the adapter is kept very well. And since now the load on the connector will decrease dramatically and there will be no need to pull the adapter back and forth, then it will sit just as tightly.
In a smartphone with (yet) a good connector, the adapter holds tight.
Let us turn to the measurements of resistance and voltage drop on the cable. We used a good Orico charger, capable of producing 2.4A, and the UM25C USB tester, well-known here.
First, check the charging current 1A. The total cable resistance together with the connector turned out to be 0.33 ohms, voltage drop 0.33V:

Increasing the current to 2A, the voltage drop is expectedly increased to 0.66V:

For two amps drop a bit too much. For comparison, the Ugreen meter cable has a resistance of 0.165 Ohm and a voltage drop across two amps of just 0.33V - exactly two times less:

So the result of the cable being monitored is at bestThe case is satisfactory. Although, when compared with others (0.391 ohms) others (0.4 ohms) others (0.4 ohms), the resistance of my cable is 0.33 ohms against their background already looks decent. And for example in others of another magnetic cable they measured different resistance at different currents - from 0.31 Ohm to 0.285 Ohm, which is already slightly better than mine.
Now about heating. I left the cable for half an hour under load 2A, I touched it - warm, but not hot. Measurement with a pyrometer showed approximately 38 degrees. So it is at least safe to charge with current 2A, if it does not bother the voltage drop to 4.4V.

We turn to the conclusions. In general, the pros and cons of such cables and adapters have been repeatedly listed, and there are still people categorically unacceptable such cables. For me, the task (saving the old USB connector) cable performs one hundred percent. The bonus is the convenience of connecting-disconnecting. There is a minus in the decent cable resistance (however, others) and, therefore, reduced charging efficiency, and the need to carry the magnetic cable with you if you need to charge the device somewhere else. Well, or buy several cables by the number of charging points, since they are sold separately from the magnetic adapter.
Comments "but cheaper here" and "but this one is better" are welcome.
