The WOLFBOX 4000A 12V Jump Starter is a rugged, all‑in‑one roadside power solution that delivers instant, high‑current starts and fast device charging in any season. Packing a 24,000mAh battery and up to 4000A peak current, it reliably jump‑starts most 12V vehicles—including cars, SUVs, pickups, vans, boats, ATVs, and light‑duty equipment—up to 10.0L gas or 10.0L diesel, while a one‑touch Boost function helps crank deeply discharged batteries with a single press. An HD LCD display makes operation intuitive by showing real‑time battery percentage, input/output status, and alerts at a glance, and the built‑in LED flashlight provides High, Strobe, and SOS modes to light engine bays, signal for help, or manage roadside tasks after dark. Beyond jump starts, the unit doubles as a powerful power bank with a 65W USB‑C in/out port that can recharge the jump starter in about 1.3 hours with a compatible charger and fast‑charge USB‑C laptops, tablets, and phones; a QC3.0 USB‑A port keeps legacy accessories powered, so multiple devices can charge simultaneously during travel or camping. Designed for real‑world durability, it operates from −4°F to 140°F and carries an IP64 rating for dust and water resistance, while smart clamps and multi‑layer protections guard against reverse polarity, short circuits, over‑current, over‑voltage, over‑charge, and over‑temperature; it also meets key compliance standards including UL, FCC, CE, and CA65. Compact and easy to stow with the included case, the WOLFBOX 4000A helps drivers handle dead batteries, cold‑weather starts, remote trips, job sites, and power outages with the confidence of pro‑grade starting power and everyday charging convenience.
