For example, the inspection preparation unit 300 may largely include an authentication jig 310 and a preparation movement unit 320. The authentication jig 310 may include a groove capable of supporting the product 2 to be authenticated. The authentication jig 310 may be made of the same material as the standard jig 100 described above. The authentication jig 310 is provided to support the side or the lower portion of the product to be authenticated 2 and support the upper surface of the product to be authenticated 2 in an open state. The preparation moving unit 320 moves the authentication jig 310 to the moving opening 210 moved by the moving rotating unit 230. When the test preparation unit 300 moves the standard product 1 to the upper part of the product to be certified 2 by the jig moving unit 200, the preparation moving unit 320 moves the authentication jig 310 upward. The authentication target product 2 is inserted into the moving opening 210 by the authentication jig 310 that is moved upward, so that it is close to the lower surface of the standard product 1. That is, the inspection preparation unit 300 prepares the product 2 to be certified in a state in which the standard product 1 moved by the jig moving unit 200 and the wireless charger can be tested for compatibility.
