Tired of waiting for your mobile batteries to get charged up? Feel annoyed when you find that your battery is low when you really need to make a call or use your mobile? Well, you don’t have to be worreid anymore. All you need to do is to know how to make a phone battery booster. Read through the article to find out how to make the booster circuit.

This article describes one of the best and easiest ways to construct a phone battery booster circuit. In case, an event has to recorded live or a long conference call has to be made and if the battery charge is very less, then such a circuit would come to your rescue. The circuit is so easy that it can be done in just 5 minutes.

The components required for the build are very minimal and are listed below:

  • 1N400x diode
  • Batteries
  • Wires

The design of the circuit is very simple. All that needs to be done is to connect the diode in series with the batteries.

Cheap phone chargers provide a voltage of about 5V. But actually, the voltage varies drastically and rises to about 6V. The voltage is mintained between 5V-5.5V under load. This tolerance is incorporated into phones.

Silicon diodes drops voltage to about 0.7V from the 6V. This is what is required to boost the battery charge and this extra voltage enables completely discharged batteries to work for a little more while.
