Your car won't start. You don't lose a battery — you lose the day's money.
No boss to call in sick to. No second car at 5am. Roadside says ninety minutes and the first ride, the first drop, the first job is already gone. This starts the car itself in about three minutes — red clip, black clip, green light, key. And it's the same device that fixes the other thing that keeps a working car parked: it's a tire inflator too — a soft tire is filled and stopped at the right number in about two minutes. Two jobs, one thing in the door pocket, there at 5am.
Everything it does, in 35 seconds — the tire, the battery, the phone.
Why two? Because the one in the work vehicle gets used, and the one in the family car is the one that stops a call from a parking lot. $109.00 for two is $29 less than buying twice.

A day off the road is money you don't get back. A fading battery doesn't recover; it picks the coldest morning. The device costs less than one lost day, once.

At $4.49 a gallon, the tire you haven't checked is the leak you can't see
For a full-time driver that stack is roughly $265–315 a year — about a week of gas — leaving through tires that aren't even low enough to light the dash. The fix isn't the gas-station pump: $2 in quarters, out of order one time in three, a cracked gauge, and you're offline kneeling in a parking lot. It's ninety seconds in the driveway before you go online, to the number on your door sticker, and it stops itself.
Not a battery. A day.
Everyone else's dead battery is an annoyance. Yours is a cancelled block, a missed airport run, three jobs rescheduled and a customer who booked the day off and now writes a review. The battery was never the expensive part.
And the timing isn't bad luck. Short trips, the phone charger, the dash cam, the heater running with the engine off between rides — a working car drains a battery harder than a commuter's, and it fades over weeks. The slow crank on Tuesday was the warning. Friday at 5am is the bill.
See it working — the tire, then the van
Nothing sped up, nothing cut. The hose goes on the valve, the pump runs and stops itself at the number. Then the clamps go on a van battery: red, black, green light, start.
Watch how little the person does. Screw on, press, wait. That's the whole skill.
How to use it — it's genuinely this easy
This is the entire manual, honestly.
Low tire
- Screw the hose onto the tire valve — same fitting as the gas station pump.
- Press the car button. It sets itself to what a car tire needs (your exact number is on the sticker inside the driver's door).
- Press start. It fills, then stops itself at the number — you can't over-inflate.
About 90 seconds on a low tire, and it stops itself.
Won't start
- Clip red to red, black to black on the battery.
- Wait for the steady green light — the smart cable checks everything for you first. If anything is wrong, it does nothing and tells you.
- Turn the key. The car starts. Unclip and drive.
The clamps cannot spark — ever. People who have never used jumper cables do this on the first try.
The van that is the job
5:10am. Tools loaded last night, first job at 7. The van cranks slow, then clicks, then nothing. You have no second vehicle to run cables from, and your neighbours aren't up. Roadside can be there in ninety minutes — the first customer can't wait ninety minutes.
Now: red clip, black clip, green light, key. The van starts. You unclip, drop the unit back in the door pocket, and you're on the road with twelve minutes to spare. Nobody had to come. You had the thing.
The soft tire at the start of a block
The tire light comes on as you accept the first delivery. The gas station pump is a detour, costs quarters, and is out of order one time in three. So you drive on it, and the slow leak becomes a flat somewhere you can't stop.
Ninety seconds in your own driveway: screw on, press car, press start, it stops itself at the number. Light off. And on a long day it charges your phone from the side port, so the app that pays you doesn't die at 4pm.
What you'll actually experience
It's loud. Like a small hair dryer, for about ninety seconds. Anything that moves air this fast is.
Give it a top-up charge every 2–3 months. Like a phone you rarely use. Door pocket, not trunk, is what makes this easy to remember.
A completely flat tire takes longer. About 6–7 minutes instead of ninety seconds. And if the tire has a hole, air won't fix it.
Below freezing, fewer starts per charge. That's lithium batteries, not a defect. Go into winter charged.
It wants at least half a charge to start a car, and it isn't waterproof. Keep it charged, keep it dry — that's the whole care routine.
A battery that has genuinely died won't come back. This starts a car whose battery is flat — lights left on, a cold night, a van that sat all weekend. If the battery itself has failed, you need a new battery. This gets you to the shop to buy one instead of paying for a tow to get there.

| How long | About 3 minutes | 45 min to 2 hours | 20 min if someone's awake | Half a day — and you still need to get there |
| What it costs you | $69.00, once | The day — and tow miles if it's flat | A favour, and a spark risk | $150–$250 plus the day |

What the numbers on the screen mean
In plain words — because nobody should need an engineering degree to put air in a tire.

Questions, answered honestly
Will it start a van, not just a car?
Yes — 12 V petrol cars and vans, and the diesel vans most trades run. It's rated at 800 A peak. If you drive something unusual (a large diesel truck, an RV), email us the engine size before you buy and we'll tell you straight.
I've got roadside through my insurance / the app. Why this?
Coverage sends a truck after — and the first ride, the first drop or the first job is gone by the time it arrives. This is the version where nobody has to come. Keep the coverage for the things this can't fix (a hole in the tire, a snapped belt).
My battery is on its way out. Shouldn't I just replace it?
Probably, yes — and this is how you get to the shop to do it without a tow. It also covers the next one, and the family car, and the morning you left the dash cam running.
Does it drain if I use the phone-charging port a lot?
A full phone charge uses roughly a fifth of it. Keep it above half if you want a guaranteed jump start that day — the screen shows the level. Charge it with the same USB-C cable as your phone, in the car, while you drive.
Is it safe if I've never touched a car battery?
That's exactly who the clamps were designed for. They cannot spark, they detect reversed connections and short circuits, and they simply do nothing until everything is right — then the green light tells you.
Will it be dead when I actually need it?
It holds its charge for months, but give it a top-up every 2–3 months, like a phone you rarely use. Keeping it in the door pocket rather than the trunk is what makes people remember. The ones that fail are the ones people never see.
Does it work in cold weather?
Yes, from -10°C (14°F) — and it watches its own temperature. Below freezing you'll get fewer jump starts per charge; that's lithium batteries, not a fault. Go into winter with it charged.
What if my battery is completely dead, not just weak?
It handles a normal dead battery — lights left on, a car that sat for days. And for a battery so drained the device can't even detect it, there's a rescue mode: a 2-second long-press forces the start. If a battery has genuinely failed, no jump starter fixes that — this gets you to the shop instead of paying for a tow to get there.
Will it work if my tire is completely flat?
Yes — about 6–7 minutes rather than ninety seconds. Important: if the tire went flat suddenly, or you can hear air escaping, or you can see damage, don't drive on it. Air won't fix a hole.
Is it loud?
Yes. Like a small hair dryer, for about ninety seconds on a low tire. Anything that moves air this fast is.
What if it breaks?
Email us with your order number and we replace it — that's the 12-month replacement warranty. And 60-day returns if you change your mind — we pay the return shipping. A person answers; support isn't outsourced.
