CHARGING
Your Jumpstarter is shipped partially charged. Therefore, you should charge the
Jumpstarter before using it for the first time. It is recommended to fully charge the
Jumpstarter after each use to ensure it is ready to use when required using one of the
methods below:

Method
1
Plug the 12V to 2.1A USB charge adaptor into a 12V socket. Use the
provided USB to micro USB cable and connect the USB end into the 12V USB
socket. Connect the micro-USB end to the Jumpstarter. (Note: Ensure you use
the provided USB to micro-USB cable provided, using other cables does not
guarantee charging performance.)
The Jumpstarter will now turn ON and start charging. The BATTERY STATUS
INDICATOR will now start to scroll in the following ways depending on its
state of charge. See battery status indicator table on page 8.
When the Jumpstarter is fully charged, after 4 hours for the IS920 and 8 hours
for the IS1220. Simply disconnect the leads and put the Jumpstarter away.

After a successful jumpstart, the Jumpstarter can rapidly recover charge from
the vehicle’s alternator. Leaving the clamps connected to the vehicle battery
for at least 40 seconds (max. 10 min) after starting the vehicle will recharge
the Jumpstarter to 100% of the original charge status.
Once the Jumpstarter is fully charged the RRT will shut off and the user can
disconnect the Black clamp and then the Red clamp. The clamps can also be
disconnected before the RRT completes, should it be required.

Note: To prolong the life of your Jumpstarter battery it is recommended to charge the
Jumpstarter after each use. If the Jumpstarter is not being used, it is recommended
to leave the Jumpstarter permanently on charge. This ensures the battery is always
maintained, fully charged, and ready for use. It is recommended to charge the
Jumpstarter before the first use, as the Jumpstarter is shipped only partially charged.
The Jumpstarter will use an audible warning (beep) to indicate a low battery status.
If the internal battery of the Jumpstarter falls below 10.5V, the Jumpstarter will
automatically switch off and prevent further discharge which could damage the
internal battery.
