Product Information

About this item

• AMERICAN-ENGINEERED SODIUM BATTERY TECHNOLOGY—Engineered in the U.S., our sodium‑ion cells pass stringent defense‑grade tests: thermal shock, vibration, puncture, overcharge, and crush. Zero fire, zero swelling, zero explosion – no thermal runaway like lithium, no leaks or maintenance like lead‑acid. With >10,000 cycles and <2% annual self‑discharge, it delivers instant peak current even after years of storage. Built by American engineers for battlefield reliability and everyday safety.
• BUILT FOR U.S. CLIMATE EXTREMES—Designed for America’s harsh weather and natural disasters – from 125°F desert heat to -40°F blizzards. Sodium chemistry maintains full starting power with zero degradation. Hurricane outages, floods, snowstorms, heatwaves – it stays fully charged and ready. While lithium swells in heat and fails in cold, K29N operates across -40°F to 185°F. Instantly starts your vehicle in any extreme, making it the trusted emergency partner for every American climate.
• 6000A PEAK CURRENT — INSTANT POWER FOR EVERY AMERICAN VEHICLE ON THE ROAD—Delivering a massive 6000A peak current, the K29N jump-starts any 12V vehicle with a flat or dead battery in just 1-3 seconds — no waiting, no repeated attempts, no frustration. This raw power handles everything on American roads: compact sedans, full-size SUVs, heavy-duty pickup trucks, 12.0L diesel work trucks, RVs for cross-country family adventures, and even marine boats for weekend getaways. Whether you drive a Ford F-250 diesel for your construction crew, a Chevy Suburban for family road trips, or a Ram 3500 for hauling heavy loads across state lines, K29N has the muscle to get you moving again.
• ZERO FIRE RISK—THE SAFEST JUMP STARTER FOR AMERICAN FAMILIES: Safety isn't a feature — it's a requirement, especially when you're storing a powerful battery in your vehicle. K29N's sodium-ion technology delivers unprecedented safety that traditional lithium and lead-acid batteries simply cannot match. This isn't just marketing hype; sodium-ion batteries have passed rigorous safety tests including overcharge, over-discharge, short circuit, needle puncture, and crush tests without any fire or explosion. For American families who store their jump starter in the glove box, under the seat, or in the trunk through scorching summers and freezing winters, this peace of mind is priceless.
• 10,000+ CHARGE CYCLES, BUILT TO OUTLAST YOUR VEHICLE—Stop replacing your jump starter every season. K29N's sodium-ion battery delivers over 10,000 charge cycles, far exceeding lithium's 500-1,000, so it lasts decades. It can be stored at 0V with minimal degradation and needs no maintenance; after months or years in storage, it fires up instantly. For daily commutes, overlanding, or emergencies, K29N removes the worry about battery aging and yearly replacement costs.
• SMART 10-LAYER SAFETY PROTECTION — FOOLPROOF FOR EVERY AMERICAN DRIVER: Worried about connecting jumper cables incorrectly? Don't be. K29N's intelligent clamps offer 10-layer safety: spark-proof, reverse polarity, over-current, over-charge, over-voltage, high-temp cutoff (185°F), and short-circuit protection. Connect backwards? System won't engage—no sparks, no damage to sensitive electronics. Critical for modern American vehicles. No technical know-how needed. Just clamp, connect, go. Stress-free roadside help for anyone.
• COMPACT & PORTABLE with 3-MODE EMERGENCY LED LIGHT— At just barely over one pound, K29N is remarkably lightweight and compact, fitting perfectly in your glove box, door pocket, center console, or under the seat. Yet despite its compact size, it delivers the raw power of units three times its size. K29N features a ultra-bright LED work light with three versatile emergency modes designed specifically for nighttime roadside situations. Whether you're stranded on a dark rural road in Montana, dealing with a flat tire on a poorly-lit city street, or signaling for help after veering off the road in a snowstorm, K29N's lighting system keeps you visible and safe. This isn't just a convenience.
• Trusted by 100,000+ American drivers, K29N delivers proven jump-starting power. Its sodium-ion cells pass industrial cold-start, cycle-life, and abuse tests; rugged housing resists rain, dust, and harsh conditions. Backed by comprehensive safety certifications and responsive customer support. Plus, enjoy a 2-year worry-free warranty – for total peace of mind. From daily commuters to cross-country road trippers, K29N is the reliable partner you need in any roadside emergency. Thousands trust it – you can too. When your vehicle fails, count on K29N to get you started and keep you moving.
