How to break the hotel charger?

If you want to crack the password of the hotel charger, you don't need to crack the password at all. You can call the front desk customer service and ask them the charging password directly. Generally speaking, they will tell the customer the password.

1. Scan the QR code on the code scanning charger with your mobile phone and jump to the payment page;

2. Select the charging method, the price and duration can be customized, and then click Charge Now to jump to the payment page;

3. After the payment is successful, jump to the password interface, with the charging time displayed in the middle and the password displayed at the bottom;

4. According to the password displayed in the background, enter the number on the key of the code scanning charger and insert it into the mobile phone for charging.

The charger is a charging device with high frequency power supply technology and advanced intelligent dynamic adjustment charging technology. Charger can be divided into power frequency machine and high frequency machine according to the working frequency of the designed circuit.

The power frequency machine is designed based on the traditional analog circuit principle. Power supply equipment inside the machine (such as transformer, inductor, capacitor, etc.). ).) are relatively large, and generally the noise is very small when running under heavy load. However, the machine has strong resistance in the harsh power grid environment, and its reliability and stability are better than those of the high frequency machine.

The high-frequency machine takes the microprocessor (CPU chip) as the processing and control center, burns complex hardware analog circuits into the microprocessor, and controls the operation of UPS in the form of software programs.
