Start the vehicle within 60 seconds after pressing the power button on Boost. After the 60-second timeout is complete, the unit must be powered off, then back on, to initiate a new jump-start sequence. The yellow power LED indicates the 60-second sequence is over and can be reset if another jump start sequence is needed.

CHARGE UP TO 4X FASTER. RAPID RECHARGE.

From 0-100% 4X Faster. Charge directly from the vehicle's 12-volt auxiliary port or the XGC4 4-Amp Power Adapter to recharge it’s 242 watt-hours lithium-ion battery in 8.5 hours.

Kevin U. ★★★★★

Was a bit skeptical about the 6250A rating, but it fired up my dump truck's dead 24V system on the first try without any sparking. The clamps feel solid and the built-in volt meter is a nice touch for checking the battery status.

Ryan K. ★★★★★

Tried it on my excavator after it sat all winter, and this thing cranked the 24V system without even slowing down. The 6250 peak amps definitely aren't an exaggeration—it felt solid the entire time.

Penelope ★★★★★

First time I've had a jump starter that handles both our 12V tractors and the 24V excavator without flinching. The 6250A rating is no joke—cranked a dead diesel in seconds even after sitting all winter.
