4000A Peak Car Jump StarterPortable Battery Booster with LCD Display, LED Light & Power Bank

🔋 A dead battery never picks a convenient time.

It's late, the parking garage is nearly empty, it's cold, and your car does nothing but click. Or you're about to leave for work and the engine won't turn over. Either way, the next hour is about waiting: for a friend with jumper cables, for a tow truck, for someone who may or may not show up soon.

The worst part is how small the problem is. Your car isn't broken. It just needs a boost, and you have no way to give it one.

This portable jump starter is that boost, in a pack you can keep under a seat. Clip the clamps to your battery, check the LCD, and start the car yourself, without a second vehicle and without waiting for help.

It also does a second job: with its built-in battery it can charge your phone, tablet or camera through its USB ports, which makes it useful on road trips and camping weekends too.

What makes it special 💛

• 4000A peak current — a 12V jump starter rated by the supplier for gas engines up to 7.2 L and diesel engines up to 5.5 L
• Up to 40 starts per charge — the supplier's rating on a fully charged unit (real results vary with temperature and engine)
• LCD display — shows the unit's status and battery level so you know where you stand before you turn the key
• Emergency light built in — so you can see what you're doing when it's dark
• 10 built-in protections — including reverse-polarity, short-circuit, over-voltage, over-temperature and spark-proof protection
• Doubles as a power bank — charge phones, tablets and other devices from the same unit

Here's all it actually takes:
1. Make sure the jump starter is charged, then connect the clamps to your battery terminals in the order shown in the manual (red to positive, black to negative).
2. Check that the LCD display shows it is ready.
3. Start your car. Once it's running, disconnect the clamps and put the jump starter back in your car.

A little ritual worth keeping

Top it up every few months, keep it where you can reach it, and treat it like a spare tire: you hope you never need it, and you're very glad when you do. It's also a thoughtful gift for a new driver, a student, or anyone who commutes in cold weather.
