Samsung EP-TA200 this charger has witnessed the rise and fall of several generations of mobile phones, called the longest used mobile phone charger, and was also dubbed by netizens as "every year."
Whether it is a mobile phone or a charger, Samsung has always used its own AFC and QC2.0 fast charging protocols.
In daily use, we can use QC charging to quickly charge the phone, and also use Samsung's charger to quickly charge most mobile power and QC standard mobile phones.
However, the record of Samsung's charger "every year" has been broken this year. An industry engineer broke the news to the charging head network: Samsung S9 original charger blocked QC2.0 fast charge! This has caused widespread concern among users. To this end, the charging head network got the original charger of Samsung S9, and made some comparison with the old EP-TA200 charger.
White is Samsung's old fast charge charger, black is the new version. From the appearance of the product alone, the new version of the charger is not much different from the old version, but the face is less "AdapTIve Fast Charging" than the old one.
In addition to the production date and S/N code, the charger model is EP-TA200, and the other parameters are almost identical. Therefore, as an ordinary user, it is difficult to distinguish from the appearance of the product.
Performance, using ChargerLAB POWER-Z KT001 test, the old version of the charge supports USB DCP protocol and QC2.0, AFC fast charge.
The new version of the charger supports the USB PD protocol and AFC fast charging, and the POWER-Z KT001 does not detect the QC2.0 fast slave protocol.
The old version of the charger supports Xiaomi 5 mobile phone (QC3.0) fast charge, 8.95V/1.34A, power is about 12W.
The new version of the charger does not support the Xiaomi 5 mobile phone fast charge, and it also appears that it can not be charged properly.
The old version of the charger supports 360 mobile phone N5 (QC3.0) fast charging, power is about 14W.
The new version of the charger cannot properly charge the 360 ​​mobile phone N5.
Samsung's old EP-TA200 charger supports Xiaomi mobile power (QC2.0) for fast charging, and the power is about 16W.
The new EP-TA200 can only charge 5V/2A to Xiaomi mobile power, and it can't charge quickly.
In the case of not connecting POWER-Z KT001, the power meter display power is 0.24W, which means that Samsung's new EP-TA200 charger can't charge the millet 5 normally (original charging line).
In the same situation without the POWER-Z KT001, Samsung's new EP-TA200 charger still can't charge the 360 ​​mobile phone N5 normally.
Summary After the test of the charging head network, Samsung's new EP-TA200 (S9 original charger) has indeed blocked the QC2.0 fast charging protocol. In addition, the test also found that the new EP-TA200 cannot supply power to the QC3.0 standard mobile phones such as Xiaomi 5 and 360 N5. Since the appearance of the two chargers is not very different, users need to pay more attention to the purchase of this charger in the future.
Satellite broadcasting has the characteristics of wide frequency band, large capacity, stable and reliable performance, wide coverage and suitable for various services. It has become the main means of transmission for radio and television. The performance of satellite ground receiving antenna is directly related to the GH/T value of satellite ground receiving equipment, which determines the viewing quality of satellite broadcasting and TV programs. Therefore, the right choice of satellite receiving antenna is an important premise and guarantee of satellite receiving. Satellite ground receiving station basically chooses two kinds of antenna, namely parabolic antenna (feedforward) and cassegrain antenna (feedback). Parabolic antenna consists of a rotating-symmetric paraboloid, that is, the electromagnetic wave reflection surface and the feed surface, the feed surface in front of the paraboloid
