About

The Whistler Jump and Go WJS-3000B is part of the Jump starter test program at Consumer Reports. In our lab tests, Jump starter models like the Jump and Go WJS-3000B are rated on multiple criteria, such as those listed below.

Jump Start (Warm): Ability of the Jump Pack to start a weak and dead battery at warmer temperatures of approximately 70 deg. F. A weak battery is when the headlights will come on and the engines starter motor will click but not start the car. A dead battery is when the lights would not come on and the starter would not make any noise.

Jump Start (Cold): Ability of the Jump Pack to start a weak battery at Zero degrees. A weak battery is when the headlights will come on and the engines starter motor will click but not start the car. Starting a car at sub freezing temperatures is most severe since the battery loses capacity. The test was done with both the cars battery and jump pack at zero degrees and with the battery at zero degrees and the jump pack at room temperature.

Reserve capacity: Reserve capacity estimates how long the Jump Pack can be used to power other electrical equipment such as charging cellphones and laptops.
