Jump Starter
How does a jump starter work?
A jump starter provides instant power to start your vehicle:
- Built-in lithium battery
- Delivers high peak current
- Works without another car
Also works as a power bank for phones and devices.
What kind of battery is in the YESPER jump starter
YESPER jump starter uses lithium polymer battery which is safe and lightweight.
Other than starting vehicles, what else can a YESPER jump starter do?
YESPER jump starter can also serve as a flashlight as well as a portable charger that can quickly charge your mobile devices, laptops, electronic tools on the road.
Why are the green and red light on the jumper cable blinking?
The jumper cable features a smart Over-Start Protection function. If you start the vehicle more than 4 times in 2 minutes, the jumper cable will turn on Over-Start Protection: The green and red light will start to blink and the battery clamps will have no output. When you disconnect the jumper cable plug from the jumper starter, the smart Over-Start Protection will reset.
How do I know if this unit is correctly connected to thevehicle?
The indicator on the jumper cable will show a steady green light when the battery clamps are correctly connected to the vehicle battery. If a steady red light comes on and the unit is beeping, the connection needs to be reversed.
Is the YESPER Jump Starter safe to use?
This unit is equipped with 8 protection features, including over-current protection, over-charge protection, short circuit protection, reverse charge protection, over-discharge protection,reverse polarity protection, over temperature protection, and reverse connection protection. It's extraordinarily safe to use.
