Hybrid Power Bank Car Jumper is a portable jumper that aims to save time to jumpstart a car.
The solar charger employs solar energy to supply electricity to devices or charge batteries. They are
generally portable. Solar charger can charge lead acid or ni-cd battery banks up to 48v and hundreds
of ampere-hours (up to 4000Ah) capacity.
When the power bank is fully charge, it can use to charge the battery car. Power bank can
only use to jump start the vehicle when it have enough power at least 80%. If power bank haven’t
enough power, that would make the battery over-discharge.

Figure 1: Summary of methodology for Hybrid Power bank Car Jumper

The project began by designing a circuit solar power bank that allows to charger the battery
without using adapter. After the battery is fully charged, the power bank can jump start the car. The
circuit is specially designed for cars that use 12V battery. The power bank use batteries of the type
Lithium Polymer battery which type is more durable, resistant to high temperatures and hold far
longer than any of Lithium Ion battery type. So, a power bank is more durable and hardy.
