For quick connections without tools
The principle of these clips is that of rapid assistance: you attach them to the battery terminals, connect the other end of the cable to the device, and the circuit is closed. Their 1.5 m length leaves time to set the equipment on a workbench, a step or the floor of a boot. Wattstunde offers them in a version with a 4mm² conductor.
Rather light uses
The thinner conductor of this version points to low-demand devices: a work lamp, a small pump, a blower, a mini compressor or a maintenance charger. A DIY enthusiast will keep it in the car boot. A maintenance electrician or an equipment hirer will use it for battery checks or low-voltage product demonstrations.
Ideas, with no promise of compatibility
- Running a small 12 V accessory when there is no cigarette-lighter socket, if its manual allows it.
- Slowly recharging a leisure battery with a suitable charger.
- Serving as a test lead in the workshop.
What the specifications say
The data retain two values: a conductor cross-section of 4mm² and a length of 1.5 m. Maximum current, the material of the jaws and any protections are not given. Assuming a high capacity would be unwise: the 4mm² section is lower than that of other models in the same series, and the connected device must stay within the range given in its manual.
The good points
A thinner conductor means a more flexible cable, easier to coil and to slip into a pouch, which is an advantage if you move around a lot. The 1.5 m length avoids working bent over the battery. Two separate clamps make polarity easier to distinguish, provided the colour coding is respected.
Procedure
- Switch off the device to be connected.
- Attach the positive clamp, then the negative one.
- Connect the cable to the device.
- Switch on and watch the first few minutes.
To remove the setup, work in reverse. A fixed link on a vehicle or a boat requires a proper installation, entrusted to a professional.

Safety
Keep flames and cigarettes away from a battery: it can emit flammable gases. Never let the jaws touch while the cable is live. Do not pull a demanding device through a modest cross-section: if the cable or clamps heat up, stop immediately. Avoid wet surfaces and do not connect to a cracked or leaking battery.
Care and storage
Gently brush the jaws to remove deposits and oxidation, then dry them. Check the sheath and the spring of each clamp before the next outing. Keep the set in a dry pouch, with the cable coiled without kinks and the clamps apart from each other.
