THE MOMENTS NOBODY PLANS FOR
A dead battery never gives you warning. By the time you have found a signal, waited for a recovery truck and paid the call-out fee, an hour of your day has gone — and it is a bill you never planned for.
A CAR PARK AFTER DARK
Everyone has gone home. The engine will not turn over.
A FROZEN MORNING
Overnight cold has flattened the battery. All you get is a click.
A LAY-BY WITH NO SIGNAL
No bars on the phone, and no one to call for a tow.
A SLOW PUNCTURE ON THE HARD SHOULDER
No garage in sight, and no foot pump in the boot.
NOT BECAUSE THE CAR IS OLD —
BECAUSE THESE THINGS PICK THEIR MOMENT.
POWER WHEN IT COUNTS
4000A.One clamp. One start.
Clamp on, press start, drive away. 4000A of peak current turns over petrol engines up to 8.0L and diesel up to 7.0L — in a car park, on a driveway, or at the side of the road in the cold.
One box. Four jobs. JUMP a dead battery · INFLATE a soft tyre · CHARGE a flat phone · LIGHT the roadside
READY WHEN YOU ARE
Charge it once. Forget it.
15,000mAh, up to 50 jump starts per charge, and around 80% of that capacity still there after months in a cold boot. USB-C in, so the cable that charges your phone tops it up too.

Frequently Asked Questions
Will it start my engine?
Will it start my engine?
It starts 12V vehicles with petrol engines up to 8.0L and diesel up to 7.0L — cars, SUVs, pickups, vans, motorcycles and boats. It is not designed for 24V systems such as heavy trucks.
What if I clip the clamps on the wrong way round?
What if I clip the clamps on the wrong way round?
Nothing happens. The smart clamps carry 10 layers of protection including reverse polarity and spark proofing, so the unit simply refuses to pass current and tells you to swap the clamps.
How quickly does the compressor inflate a tyre?
How quickly does the compressor inflate a tyre?
Set your target pressure, connect the hose and press start. A typical car tyre goes from soft back to 30–35 PSI in about a minute, and the compressor shuts itself off when it reaches the number you set.
How long does it hold charge sitting in the boot?
How long does it hold charge sitting in the boot?
It is rated from -20°F to 70°F and keeps roughly 80% of its charge in the cold. Topping it up every three months or so keeps it ready without any thinking.
Can I charge my phone from it?
Can I charge my phone from it?
Yes. The 15,000mAh pack doubles as a power bank with dual USB-A and USB-C outputs, so it will refill a phone several times over or run a tablet while you wait.
