The Problems You Don’t Want to Deal With

Running Late. Car Won’t Start.

A dead battery can turn a normal morning into a major delay.

No Warning Before Your Battery Gets Weak.

Battery problems often build quietly. Know what’s happening before your car refuses to start.

A Backup That Needs a Backup.

A traditional jump starter only helps if you remember to keep it charged.

Install Once. Always Ready.

Traditional jump starters react. XT700 helps you stay ahead.

Complete Automatic Operation

Choose between a semi-permanent connection or a temporary hookup - the XT700 handles the rest.

Auto-Charge

Always Ready. No Charging Routine. When its charge drops below 80%, the XT700 automatically tops itself up from the vehicle battery. As long as the battery stays above 5V, your backup stays ready when you need it.

Auto-Discharge

Extra Power, Every Time You Start. Once installed, the XT700 automatically releases stored energy during every start, sharing the load with your vehicle's battery for a stronger, more reliable crank.

Auto-Wake

No Need to Wake It Up Yourself. Get in and go. The XT700 automatically powers on when it senses vibration or a voltage change, keeping it ready when your vehicle needs it.

Auto-Sleep

Park It and Forget It. The XT700 automatically goes to sleep 20 minutes after the engine stops, helping reduce unnecessary power use while your car sits.
