Description

A flat battery always announces itself at the worst possible moment, and it is never the battery you were watching. The Cold Start is built for that specific failure: a 22,000mAh pack with up to 2000 amps of peak output, sized to turn a 12V engine without a second vehicle, a set of cables, or a stranger with a good mood.

Inside, four cells drive the discharge path with an 85 to 90 percent conversion rate, and the enclosure carries the safety architecture a lithium pack in a car boot requires: a warning light, an SOS mode, a work light, and a cigarette-lighter socket output alongside USB. Two-way fast charging means the pack refills quickly after use instead of sitting flat until the next emergency, which is how most portable starters quietly become useless.

At roughly 0.65 kilograms it lives under a seat or in a door pocket without being noticed, and the certification set (CE, FCC, RoHS and PSE) reflects the fact that this is a lithium battery intended to sit inside a vehicle through temperature swings. Two output tiers are offered: the 1600A Jstar Zero and the 2000A Jstar One, so a motorcycle owner and a diesel van owner are not forced into the same specification.

The best jump start is the one that never needs a second car.

Where It Gets Used

Commuters who park outdoors through winter and would rather not rely on a stranger's goodwill at minus ten. Delivery fleets that keep one unit per van because a dead battery costs a route, not a morning. Campers and overlanders who need a 12V socket and a light source that do not depend on the vehicle's own battery. Motorcycle owners who want the 1600A tier in a jacket pocket. Anyone who has already replaced a battery because the previous one was flattened once too often by a light left on.

Questions From Owners

Q: Will 2000A damage my vehicle electronics?

The pack delivers current only when the jump-start output is engaged, and the clamps feed the starter circuit the way a donor battery would. Connect the clamps with correct polarity, engage the output, start the engine, then disconnect. The peak figure describes capability under demand, not a constant push.

Q: How many jump starts should I expect per charge?

That depends on engine size and how depleted the battery is. A single charge covers multiple starts on passenger cars; a large diesel that needs several seconds of cranking will draw down the pack faster. Recharge after every use rather than waiting for the next emergency.

Q: What is the difference between Jstar Zero and Jstar One?

They are the two output tiers: 1600A and 2000A peak respectively. Choose the lower tier for motorcycles and small petrol engines, and the higher tier for larger petrol or diesel engines.

Q: Can I leave it in the car in summer?

It is certified for in-vehicle use, but lithium cells age faster at sustained high temperature. Store it out of direct sun and away from the floor pan, and check the charge level periodically rather than only when you need it.

Q: Can it charge a phone or run a 12V accessory?

Yes. It provides a USB output and a cigarette-lighter socket, which makes it useful as a general portable power source, not only as a starter.

Q: How do I recharge the pack itself?

Through the two-way fast-charge path described in the specification, using the supplied charging arrangement for your region. A full recharge takes a few hours depending on the adapter output.

Q: Does the pack lose charge while stored?

Any lithium pack self-discharges slowly over months. Check the level every few months and top it up, so the one time you need it the pack is not the second dead battery in the car.

Works well, recharge it regularly

No complaints about the starting performance. The one thing nobody tells you is that a lithium pack left alone for a year will be flat when you need it, so set a reminder to top it up every few months.

Lives in the door pocket

Light enough that I forget it is there until I need it. Used it twice for other people in car parks before it ever helped me, which says something about how often batteries fail in winter.

Started a diesel van at minus six

The 2000A tier was the right call. Van had been sitting for three weeks in the cold and it turned over on the second attempt. The pack still showed most of its charge afterwards.
