Description
A dead battery never picks a good moment. This portable car jump starter puts 5000A of peak starting power in a case small enough to live in your glove box, so a flat battery on a trail head at dusk becomes a two-minute delay instead of a tow truck and a ruined weekend. It starts 12V engines up to 8.0L gas or 7.0L diesel, and when nobody needs a jump it works as a 20000mAh power bank and a 400-lumen work light.
The car jump starter you forget about until the day it saves you
Most people buy a car jump starter after the first time they needed one. The ones who buy before keep it charged and stop thinking about it, because a lithium pack holds its charge for up to 24 months on standby. That is the whole point: it sits in the vehicle through a summer of fishing trips and a winter of cold mornings, and it is still ready when the key clicks and nothing happens.
Features
- 5000A peak output — starts 12V engines up to 8.0L gasoline or 7.0L diesel, which covers most trucks, SUVs and sedans on the road.
- 20000mAh power bank — two USB ports with QC 18W fast charging for a phone, tablet or headlamp while you are away from an outlet.
- 400-lumen LED light — three modes (steady, SOS and strobe) running up to 10 hours, so a roadside repair after dark is not done by phone screen.
- LCD status screen — shows charge level, charging status and error reporting at a glance, instead of guessing from a row of blinking dots.
- 10 built-in protections — including reverse polarity, short circuit, over-current and over-temperature safeguards on the smart clamps.
- Fits in a glove box — the unit measures 17.6 x 9 cm and the complete kit ships at 0.9 kg.
- Ships from a U.S. warehouse — free shipping, with delivery in 7 to 20 business days.

What comes in the box
The kit arrives complete: the car jump starter unit, the smart jumper clamps, a USB-C charging cable and a zippered storage case that keeps the clamps and cable together. There is one version of this product and one option to choose, the U.S. warehouse, so there is no guessing between models at checkout. Charge it fully before the first use and top it up every few months.
Where it fits
Overlanding and dispersed camping are where a car jump starter earns its keep, because that is where there is no one to flag down. It is equally at home in a work truck, a boat trailer tow vehicle or a second car that sits unused for weeks. Anglers who run a bilge pump and a fish finder off the cranking battery know exactly why this belongs in the dry box.
Care and maintenance
Recharge the car jump starter to full every three to six months even if you never use it, since lithium packs self-discharge slowly. Store it between roughly -20°C and 60°C and keep it out of direct sun on a dashboard in summer. Always connect red to positive and black to negative, and let the clamps confirm a correct connection before starting. For general guidance on handling lithium battery products, the U.S. Consumer Product Safety Commission publishes battery safety standards.
Frequently asked questions
Will this car jump starter work on my engine?
It is rated for 12V engines up to 8.0L gasoline or 7.0L diesel, which covers the large majority of passenger vehicles, pickups and SUVs. It is not intended for 24V systems.
How many jumps do I get on one charge?
That depends on engine size, temperature and how deeply the vehicle battery is drained. A cold, large diesel takes more out of the pack than a warm four-cylinder.
Can I leave it in the car all year?
Yes, and that is the intended use. Avoid leaving it on a dashboard in direct summer sun, and recharge it every three to six months.
Does it charge phones as well?
Yes. Two USB ports with QC 18W fast charging make it a 20000mAh power bank whenever it is not being used to start a vehicle.
How fast does it ship?
This car jump starter ships free from a warehouse inside the United States, with delivery in 7 to 20 business days. See more overland gear or browse the full MAXELTI Active shop.
