Mobile Battery Bank Circuit Diagram

In the regulator circuit for this power bank i use 5v regulator ic l78s05 this is not a normal lm7805ct ic but pin out and looking size is same as any 78xx regulator ic.

Mobile battery bank circuit diagram.

Power bank circuit diagram. As can be seen in the above design a charger circuit charges a 3 7v cell once the charging is completed the 3 7v cell box is carried by the user while traveling and whenever the user s cellphone battery goes down he simply connects this 3 7v cell pack with his cellphone for topping it up quickly. Nowadays mobiles can also be charged using the usb outlet of pc. The power banks are additional power source and it ensures the power backups when we travel or in emergency situations.

Tp4056 module with battery protection circuit. Below is the circuit diagram for our power bank. So i suggest to use only this ic. 3 7v power bank mobile battery charger circuit diagram 3 7v power solar battery charger circuit with voltage regulator wireless power transfer circuit wireless mobile charger 40000mah lipo power bank 10 steps with pictures what is a power bank charger what is the mechanism of its working.

3v to 5v boost converter with 1a current control. Usb stands for universal serial port. The mobile charger circuit presented in this project can give 4 7v of synchronized voltage wysiwyg imageupload for charging the phone. Power bank modules connection diagram it contains three stages first one is tp4056 li.

As we can see its fairly easy to make a power bank with li ion battery tp4056 module and a boost converter. But if you use lm7805ct then the output current is not more than 1 a in this case your mobile battery take more hour to get charge.
