Xiaomi power banks can be taken on planes and trains. However, most airlines and train stations have regulations that stipulate the power bank's rated energy should not exceed 100Wh. This is to ensure the safety of all passengers and to comply with international safety standards.
To determine if your Xiaomi power bank meets this requirement, please refer to the following methods:
1. Please check your power bank’s capacity, which is marked on the device or specified in the user manual;
2. It's also important to note that different airlines and train companies have varying policies. Therefore, it is highly recommended that you consult directly with the airline or train company before your trip to ensure compliance with their specific requirements. This will help avoid any inconvenience or issues during security checks.
