• Large screen shows real-time status and alerts
• Intuitive Force Start button and simple control layout

What else can this unit do besides jump-starting?

The TJ18 doubles as a fast-charging power bank and an emergency light. It supports PD18W fast charging to recharge the unit quickly and to charge phones, earbuds, and other USB devices while you’re away from outlets.

• PD18W fast charging: full charge in about 2–2.5 hours
• USB output for smartphones and small electronics on the go

Who is this for? The AVAPOW TJ18 is aimed at drivers, outdoor enthusiasts, and professionals who want a compact, dependable emergency starter that’s easy to operate and quick to recharge. It fits anyone who values clear diagnostics (via the 4" display), fast recharging between uses, and multi-function utility—campers, delivery drivers, fleet owners, motorcyclists, and homeowners with occasional battery trouble will all find it useful. Remember to fully charge before first use, recharge every 2–3 months if stored, and avoid attempting starts under load for longest service life.
