Is the loss of property electricity charge reasonable?

Reasonable. The reason for this is the following：

1. Power equipment will suffer certain losses in the operation process, which will be borne by the property management company and compensated by increasing the owner's electricity bill.

2. The electricity bill signed by the property management company and the owner has clearly listed the cost of normal line loss, so it is reasonable to charge the owner for power loss.

3. As the main body of business activities, property management companies need to maintain certain economic benefits while providing services, so they will realize profits by charging power loss fees.
