FREQUENTLY ASKED QUESTIONS

Q. How do I work out how long my appliance will run from the Jumpstarter
A. When the jumpstarter is fully charged the battery will be able to provide 44 Amp hours
of 12V power. If you have an appliance that uses 2.5 Amps and you use it for one hour,
you have just used 2.5 Amp hours.
For example:-
The jumpstarter is powered by 2 x 22Ah (44Ah) batteries and you are powering a small
TV drawing approximately 2.5 Amps
Equation: 44 Amp hours ÷ 2.5 Amps = 17.6 Hours (18 hours)
Q. How can I improve the charging time when charging from my vehicle?
A. Disconnect any appliances connected to the jumpstarter. Car cigarette lighter sockets
are usually connected to the battery with small (light) cable. If your jumpstarter is
taking longer than 11–13 hours to recharge, the cable between the vehicle's battery
and cigarette lighter socket may require upgrading.
Q. When I use the 12 Volt DC sockets the appliance does not work?
A. Check to make sure the appliance does not exceed the rated current of the socket used.
Accessory Socket:
Heavy Duty Accessory Socket:
Maximum Combined Load:
If the load on your jumpstart exceeds 20A the jumpstarter will disengage the power
accessories. To restart the jumpstarter and continue powering your appliance press the
OVER RIDE button on the front of the jumpstarter.
Q. When I connect the jumpstarter up to the battery the alarm is going off?
A. The jumpstarter is designed to give off an alarm in the following circumstances.
1. If the positive and negative clamps are touching each other.
2. Reverse connection i.e. positive clamp connected to negative terminal or negative
clamp connected to positive terminal.
