Product Overview
The Ecolite JS70 is a compact, high-performance portable lithium jump starter designed to safely revive dead vehicle batteries in seconds. Engineered for convenience and reliability, it delivers powerful starting current in a lightweight, pocket-sized package—making it an essential emergency tool for drivers, outdoor enthusiasts, and fleet operators. With multi-layer safety protection, long standby time, and wide operating temperature range, the JS70 ensures you’re never stranded by a dead battery.

Instant Power When You Need It
Capable of jump-starting 12V gasoline and diesel engines up to a certain displacement (e.g., 7.0L gas / 5.5L diesel), the JS70 provides peak currents sufficient to crank even large SUVs, trucks, and boats. Its high-rate lithium cells deliver the burst energy required for reliable starts in seconds, without the need for another vehicle.

Compact, Lightweight & Easy to Carry
Weighing significantly less than traditional lead-acid booster packs, the JS70 fits easily in a glove compartment, backpack, or emergency kit. Its ergonomic design and intuitive interface make it simple to use—even for those unfamiliar with jump-starting procedures.

Multi-Layer Safety Protection
Built with an advanced Battery Management System (BMS), the JS70 protects against reverse polarity, overcurrent, overcharge, and short circuits. Spark-proof technology ensures safe connection, while high/low temperature protection allows operation in extreme climates (-20°C to 60°C). Users can jump-start with confidence, knowing the device is safeguarding both vehicle and user.

Multi-Functional Emergency Companion
Beyond jump-starting, the JS70 doubles as a portable power source:

• USB ports (QC3.0 / PD) for charging smartphones, tablets, and other devices

• 12V DC output for tire inflators, car refrigerators, or other accessories

• Built-in LED flashlight with multiple modes (SOS, strobe) for roadside emergencies or camping

Long Standby & Quick Recharge
With ultra-low self-discharge rate, the JS70 retains its charge for months—ready whenever you need it. When depleted, it recharges quickly via included AC adapter or car charger, ensuring minimal downtime.
