3.7 volt to 12 volt converter

This is a 3.7-volt to 12-volt converter circuit diagram:

18650 model 3.7 voltage battery is a common battery. everywhere we can use this battery. the laptop used this battery. mobile power bank using this battery. Small hand fan using this battery. bicycle using this battery. many power banks are using this battery using a BMS charger. but here this 12-voltage battery can charge using a mobile charger. and also no need BMS circuit. only using 2 6-pin switches.

3.7-volt battery charger using a mobile charger. this is an auto-cut battery charger. the charge will off when the battery will be full.  this circuit needs to make 3.7 volts to 12-volt converter circuit diagram.
