Description
A flat battery does not wait for someone to be around
A battery always goes flat in the wrong place: an empty car park on a Sunday evening, a frosty morning, a car that has stood for three weeks. This unit fits in the glovebox and replaces both the jump leads and the obliging car you would have to find.
What it does, in practice
- Restarts a petrol engine up to about 3.0 L: 600 A peak, 300 A cranking
- Charges a phone from its 5 V / 2 A USB socket
- Lights up, with a three-mode LED lamp: steady, SOS, flashing
- Fits in 13.7 × 7.8 × 2.4 cm, at 450 g
The gesture, in three steps
Red clamp on the +, black clamp on the −, start button. Once the engine is running, you remove the clamps and close the bonnet. The manufacturer's instructions set out the procedure: read them before first use, reverse polarity is unforgiving.
A device you keep charged
That is the only discipline it asks of you: a full charge when it arrives — about four hours — then a check two or three times a year. A flat booster on the day you break down is no use at all. The manufacturer states operation from −20 °C to 60 °C; like any lithium battery, it likes neither full sun behind a windscreen nor knocks.
Worth knowing
- Check your engine size — this model targets petrol up to about 3.0 L; large diesels call for something more powerful.
- Dispatched from a warehouse in France : delivery is faster than our usual times.
- Free shipping within mainland France, with no minimum order.
- 14 days to change your mind, returns accepted with no reason required.
When it earns its place
The car park nobody walks past
A flat battery on a Sunday evening in an empty car park: there is no neighbour to ask for cables, and no breakdown truck for an hour. That is exactly the situation you buy a booster for.
The car that sits too long
Second car, van, classic car: a few weeks without driving is enough to flatten a battery. A charged unit in the boot saves you thinking about it.
The morning chill
A tired battery gets through the summer without a murmur and gives up on the first −5 °C morning. The unit stays in the car and earns its place the day the starter struggles.
The weekend far from anywhere
Camping, hiking, the seaside: where there is no signal and no breakdown service, the lamp and the USB socket earn their place as much as the jump-start function.
Which kit to choose
| Kit | What it contains | Who it is for |
|---|---|---|
| Unit only | The booster and its clamps | You already have somewhere to keep it |
| With cover | The booster, its clamps and a hard case | The unit lives in the boot and travels |
| With safety clamp and cover | The booster, the case and clamps with electronic protection | You would rather not have to think about the wiring |
The colour of the unit — red or black — changes none of its specifications.
Questions we are asked about this product
Will it start my car?
The manufacturer states 600 A peak and 300 A cranking, which covers petrol engines up to about 3.0 L. Beyond that, and for most large diesels, you need a more powerful model. If in doubt, check the engine size on your registration document before ordering.
How does it connect?
The clamps go on the battery, red to the +, black to the −, before you press the start button. Once the engine is running, you remove the clamps and close the bonnet. Read the instructions before first use: reverse polarity can damage the unit and the vehicle alike.
Do you need to charge it before use?
Yes. The manufacturer recommends running it down once with the lamp, then charging it for at least four hours before the first jump-start. After that, check the charge two or three times a year: a flat booster is no use on the day you need it.
Can it stay in the car all year round?
The manufacturer states operation between −20 °C and 60 °C. As with any lithium battery, avoid leaving it in full sun behind a windscreen in summer, and do not store it near anything that could crush or puncture the casing.
Does it also work as a power bank?
Yes, through its 5 V / 2 A USB socket: enough to recharge a phone. It is not meant to replace an everyday power bank, but keep enough charge in it for its real job, starting the car.
How long will it take to arrive?
This model ships from a warehouse in France, unlike our other products: delivery is markedly faster than the usual 7 working days maximum. You receive a tracking number as soon as it ships.
