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.
Easy Control In Your Hand
Real-time battery & XT700 Monitoring to detect issues early.
Live Data Monitor
Logs every 2 minutes with real-time battery and XT700 status.
Low Battery Notifications
Set two custom voltage warnings. Get automatic push notifications when levels fall too low.
Forced Start Mode
When the battery is too weak for a normal start, activate Forced Start in the app to give the engine the extra cranking power it needs.
Cranking Trend Tracking
Track battery voltage trends at a glance, with live current draw monitoring during every XT700 jump-start session.
Supercap Jump Starter That Never Dies
As long as your vehicle battery stays above 5V, the XT700 can recharge itself from the vehicle’s available power. Even after heavy use, it can quickly build its energy back up and stay ready for the next start.
