In theory, it is feasible to charge the door lock with reverse wireless charging of the mobile phone, but in fact, many problems need to be paid attention to. First of all, whether the door lock supports wireless charging and whether the charging interface is compatible with the reverse wireless charging function of the mobile phone needs to be confirmed.
Secondly, the output power of the reverse wireless charging of the mobile phone is relatively small, and it may take a long time to charge the door lock to get sufficient electricity. In addition, the use of mobile phone charging may have insufficient power or the problem of the phone weighing power management during the charging process, which also needs to be noted. Therefore, in actual operation, it is best to choose to use a normal battery or charger to charge the door lock.
