A PORTABLE STARTING SOLUTION
STARTING CURRENT
A flat battery.
A way forward.
Keep portable starting power close at hand for compatible cars, motorcycles, ATVs and other 12V vehicles.
Starting performance depends on battery condition, engine size, charge level and temperature. Follow the product and vehicle instructions.
ONE DEVICE. TWO ROADSIDE JOBS.
From the battery
to the tires.
Bring a jump starter and air compressor together in one portable unit. Use the hose for tire inflation, or attach a suitable nozzle for balls and other compatible inflatables.
150 PSI is the compressor’s maximum pressure. Use the pressure recommended for your vehicle, tire or inflatable.
POWER BEYOND THE ENGINE BAY
A useful reserve.
Wherever you stop.
The 7200mAh battery supports jump starting and USB charging for compatible devices. Recharge the RJ21 through its USB-C input before your next trip.
WHEN DAYLIGHT RUNS OUT
Light for
the next step.
Illuminate a roadside check or a campsite with the built-in LED flashlight. Brightness options and signaling modes add useful light when you need it.
