Smart Clamp adds a protection box with warning lights that flags clamps on the wrong terminals before you jump. Straight Clamp is the plain cable. Same price.
Keep it in your car for 30 days. If it doesn’t earn its spot, we refund it.
Why 5 minutes: clamp on, press power, turn the key — the engine is running in under a minute. A low tire takes a few more, and the pump stops itself at the PSI you set. No second car, no waiting for whoever is on call tonight.
A 1000A jump starter, a 150 PSI tire pump that stops itself, a phone charger and an SOS light — in one unit smaller than a hardcover book. The two roadside problems that strand most drivers, handled without calling anyone.

“My car won’t start.” “My tire’s flat.” Both usually end the same way — standing next to the car, waiting for somebody else. This puts the fix in the car before the call happens.
1000A peak, 500A starting, for 12V gasoline cars, small SUVs, motorbikes and mowers. Clamp on, press power, turn the key. No second car, no cables across two bumpers.
Up to 150 PSI. Set the pressure from your door sticker and press start — the digital display counts up and the pump stops itself at the number. Car, motorbike, bike and ball modes.
A 6000mAh battery with two USB outputs. A dead phone at the side of the road is half the problem — this charges it while you sort the other half.
Flashlight, strobe and SOS. Long-press the power button and you can see the battery terminals at 11pm in an unlit lot.

Charge it, try it on your own battery, pump up a tire with it. If it isn’t the thing you’d grab first when the car won’t start, write to us within 30 days of delivery and we refund the order.
A full charge out of the box, so the first test is a fair one.

If it runs on gasoline with a 12V battery, almost certainly — that covers most sedans, hatchbacks, crossovers and small to mid SUVs, plus motorbikes, mowers and ATVs. It delivers 1000A peak and 500A starting current. It is not built for diesel engines, and on a big V8 truck with a completely flat battery a higher-amp unit is the better tool. If you are unsure, send us your make and model and we will tell you straight.
That is who it is built around. The clamps are colour-coded red and black, the cable only plugs into the unit one way, and the manual walks through the order: red to plus, black to minus, press power, start. It is far simpler than jumper cables, which need a second car and the right sequence across two batteries. Practise once in the driveway and they will know it cold.
Both start the car the same way, and both cost the same. The smart clamp has a small protection box on the cable with indicator lights: it checks the connection before any power flows, so if the clamps are on the wrong terminals or touching each other it warns you and holds the jump instead of sparking. The straight clamp is the plain cable — the clamps plug straight into the unit with no box in between, so getting red-to-plus right is on you. For a new driver, or anyone who jumps a car twice a year and has to think about which way round it goes, take the smart clamp. That is why it is pre-selected.
Months sitting in the car. Lithium packs lose a little charge over time, so top it up every three months over USB-C and after each use. The display shows how much is left before you rely on it.
It is rated to work from −20°C to 60°C, which covers most winter mornings. Like any battery it gives its best when it is not frozen solid, so on a brutal night keep it in the cabin rather than the trunk, or bring it inside with you.
Topping a low tire up by a few PSI takes a minute or two; filling one that is properly flat takes longer, depending on the tire. You do not have to watch it either way — set the PSI and it stops itself. A tire that keeps going flat has a puncture, and this gets you to the shop on it.
Write to us within 30 days of delivery and we refund the order. No form, no list of questions — reply to any email from us. Orders are processed in 1 to 3 business days and ship tracked, so you can see where it is from the moment it leaves.
