There's something wrong ... ???

Who buys cheap, buys .... and who ordered in the Far East must always expect surprises and should look closely. So it struck me that this power supply and with the product: "RXYYOS Waterproof 5 meters set: 5 meters 3528 120 LED / m 600 LED LED Strip" power supply shipped externally have the same case and so I looked at the name plates even closer and found that both power supplies to both the exact same model number (JY071480U) as well as the exact same serial number (JY08101159)! Although it is the model reviewed here is a power supply with 72 Watt and the model for LED strips supplied to a power supply with only 60 Watt! The barcode with the numbers above it (AT0012720001) are identical!
The nameplates differ only in the electrical values. At 72W Model 6A output current and 1.8A input current are given and the other device only 5A output current and 1.5A input current.

This had now awakened my curiosity and led to a step which can not be recommended for imitation! On the contrary, please, please do not imitate!

Both housing I have now weighed to assess to whether the internal electronics could also be identical, if possible. However, the display of the letter scale weights differed significantly. Still, I wanted to find out and opened both housing carefully (see photos).
And yes - the 60W model of 10m long LED strip is a narrow board with other assembly and the device also lacks such a screen as in the photo at left 72Watt model can be seen. While the electronics of the rated this model fills the housing precisely, in the case of weaker power supply remains abundant air.

In the functional test, there was the way with two devices at times no problems, not even what (etc. interference to radio communications) refers to the electromagnetic compatibility, as I had already had to make other experiences ... Also, no audible noise could be heard. Bin then curious how it evolves with the durability.

Only two stars, I give the products, because it's just not very inspiring trust to use the same type of signs for different devices! Although they differ in the details of the electrical properties of the devices accordingly.
