Jump N Start 800 Amp Jump Starter and Tire Inflator

Two of the most common roadside breakdowns — dead battery and flat tire — solved by one portable device. The Battery Tender® 800 Amp Jump Starter and Tire Inflator combines a lithium jump starter powerful enough for V8 engines with a built-in air compressor that inflates a standard car tire from completely flat to full in eight minutes. No jumper cables. No gas station air pump. No roadside assistance. One compact unit that fits in the trunk and handles both emergencies.

800 Peak Amps — Starts V8 Gas and Diesel Engines

At 800 peak Amps, this portable car battery jump starter handles any 12V gas engine up to V8 and diesel engines up to 5.0L — full-size passenger vehicles, SUVs, trucks, and larger vehicles that smaller 600 Amp units cannot start. The spark-proof safety system confirms the connection before current flows, protecting the vehicle's electronics and the unit regardless of lighting conditions or urgency.

Built-In Air Compressor — Jump Starter with Tire Inflator

The integrated air compressor inflates a standard passenger car or SUV tire from completely flat to full in approximately eight minutes. Digital PSI display and auto-stop at preset pressure take the guesswork out of inflation. No gas station. No separate pump to carry. Works for car and truck tires, bicycle tires, motorcycle tires, sports equipment, and inflatable accessories — one tool that covers every inflation need.

This is the jump starter with air compressor that replaces two roadside emergency tools with one compact unit.

How to Jump Start a Car Without Jumper Cables

Jump starting a car is faster and safer with a portable jump starter than with traditional jumper cables:

1. Connect the red clamp to the positive (+) terminal on the dead battery
2. Connect the black clamp to a ground point or the negative (−) terminal
3. Spark-proof technology confirms the connection before current flows
4. Start the vehicle — most engines respond within 1–3 attempts
5. Disconnect and store

Traditional jumper cables require a second vehicle, correct nose-to-nose positioning, and knowledge of connection sequence. The Battery Tender® 800 Amp requires none of that — and handles V8 engines that many portable jump starters cannot.

USB Power Bank for Daily Use

The internal lithium battery powers the jump starter, the air compressor, and USB charging outputs from the same stored charge. USB outputs charge phones and tablets when neither the jump start nor the inflation function is needed — making this a portable power bank that earns its daily carry justification beyond emergency use.

Why Lithium Beats Lead-Acid in a Portable Jump Starter

Lead-acid jump boxes are heavy, lose charge in storage, and lose output capacity in cold temperatures. Lithium technology delivers consistent peak Amps in cold weather when batteries are hardest to start, holds charge for months between uses, and weighs significantly less than equivalent lead-acid units.
