Is it possible to charge a tablet if the charging connector is broken?

First, try to determine the degree of damage. It happens that the connector does not work due to the fact that the contacts simply came off. In this case, soldering back these same contacts will most likely help. If the problem is much more serious, then you should resort to direct tablet charging.
Charging the tablet directly
The process involves taking a working battery from another device and connecting its terminals to the battery that needs to be charged.
Consider the fact that with such a connection, the voltage and current of the batteries must match.
With direct charging, electricity will be gradually transferred from one source to another, but be aware that this method can damage both batteries. So that you do not take too much risk, we suggest that before carrying out such an operation, you contact a technical service center, where qualified specialists will help solve this problem.
