How to Store Your EV Charging Cable Properly

Store your EV charging cable coiled loosely, kept dry, and off the ground, either in a boot bag or on a wall holder near your charge point. The two things that shorten a cable's life are being trodden on and being left in a damp puddle, so the goal is simple: keep it clean, keep it off the floor, and never crush the connectors. A soft storage bag like the Ring EV Cable Storage BagRing EV Cable Storage Bag£17.70Buy on Amazon works if you carry your cable in the car, while a wall holder is neater for a home wallbox. If you are choosing a new lead, our Type 2 cables come in lengths that coil down easily.

What is the correct way to coil an EV charging cable?

Coil it loosely into large loops, roughly the diameter of a dinner plate, rather than winding it tight around your arm. Tight, kinked coils stress the internal copper conductors over time and can leave the outer sheath with permanent set marks. The over-under method, where you alternate a normal loop with a reversed loop, stops the cable twisting and helps it lie flat next time. Secure the coil with the cable's own hook-and-loop strap or a soft tie, never a hard cable tie that digs in. For more detail, see our guide on how to coil an EV charging cable.

Should you use a storage bag or a wall holder?

Use a bag if you charge in different places and carry the cable with you, and a wall holder if the cable lives at home next to your wallbox. A bag keeps the boot clean and stops the connectors rattling around, which is the main way pins pick up scratches and grit. A wall holder keeps the connector off the ground, protects the pins, and makes the cable quick to grab. Many drivers end up with both: a holder at home and a bag for the spare lead in the car.

Why does keeping the cable dry matter?

Type 2 connectors are designed to be weather-resistant when plugged in and mated, but that is different from leaving a loose connector sitting in standing water for hours. Water is not usually a shock risk with an unpowered, unplugged connector, but grit, road salt and moisture sitting on the exposed pins can cause corrosion and dull the contacts over time. That is why storage aims to keep the connector ends off the ground and reasonably dry. A water-resistant bag or an under-cover wall holder does the job. Avoid claims that any bag is fully waterproof unless the listing says so.

Where should you mount a wall holder?

Mount it within easy reach of your wallbox, high enough that the connector hangs clear of the ground and any puddles, and under some cover if you can, such as a porch, carport or garage. Fix it into solid masonry or a stud, not just plasterboard, because a cable plus connector has real weight and will pull a weak fixing loose. Position it so the cable drapes in a gentle curve rather than a sharp bend at the connector. If it lives outdoors fully exposed, accept it will need wiping down more often.

What should you avoid when storing a cable?

Avoid four things: crushing the connectors under other boot items, winding the cable tight enough to kink it, leaving it coiled in a puddle, and dragging it across gravel or grit that scratches the pins. Do not hang it from the connector itself in a way that puts all the weight on the plug body. And do not store it soaking wet in a sealed bag, as trapped moisture encourages corrosion. Let it dry first, then coil and bag it. A little care here adds years of reliable use.

Frequently asked questions

Can I leave my EV cable outside all the time?

You can, but it will wear faster. Type 2 connectors are weather-resistant when mated, yet constant exposure to rain, frost and road salt dulls the pins and ages the sheath. A wall holder under cover, or bringing the cable indoors, keeps it in better condition and also reduces the chance of opportunistic theft.

Will coiling my cable tightly damage it?

Over time, yes. Tight, repeated coils stress the internal copper conductors and can leave permanent kinks in the sheath. Coil in large, loose loops around the size of a dinner plate and use the supplied strap rather than a hard cable tie. This keeps the cable flexible and easy to lay out next time.

Do I need a special bag or will any bag do?

A purpose-made EV cable bag is padded and shaped to hold the coil and protect the connectors, which a random holdall will not do as well. It also keeps grit off the pins and the boot clean. If you charge on the move, a dedicated bag is a small spend that protects a much pricier cable.

Is it safe to store a wet cable?

It is safe when unplugged, but not ideal. Sealing a soaking cable in a bag traps moisture around the connectors and encourages corrosion. Let it drip and air dry first, then coil and store it. If it lives on a wall holder, position it so water runs off rather than pooling on the connector.

Should the connector face up or down on a holder?

Face the connector downwards or sideways so water drains away rather than settling in the pin housing. Most wall holders are shaped to hold the connector at a slight angle for exactly this reason. Keep it high enough that the connector never touches the ground.

How do I stop my cable getting tangled?

Use the over-under coiling method and secure the coil with the cable's strap before storing. Keeping the cable in a bag or on a holder, rather than loose in the boot, is the single best way to stop tangles and knots forming as the cable shifts about while you drive.

Good storage is the cheapest way to make a charging cable last. Coil it loosely, keep it dry, and give it a home either in a bag or on a wall holder rather than the floor of the boot.
