Unfortunately, it cannot. The HULKMAN Alpha product is a jump starter, not a battery charger.
Note: HULKMAN Sigma 1 and Sigma 5 battery charger are availble on Amazon and HULKMAN official website.
Differentiate jump starter from battery charger:
1) A jump starter delivers an instant power which is supposed to kick-start a dead battery.
2) A battery charger is a device that requires time to recharge your car battery by delivering a steady flow of current. Typically, it is a bulkier solution which isn’t always pleasant.
