The two ways a portable charger’s cable gets hurt are both mechanical, and both start as damage to the jacket: kinks, from bends that are too tight or held too long, and crush damage, where a tyre, a door or a heavy object presses the cable flat. Both are prevented by how you route and coil the cable — and neither is a home repair. Once a charging cable is cut, cracked or crushed, the answer is to stop using it and replace it, never tape it and carry on.
Key Takeaways
- Kinks come from tight coiling and forced bends; crush damage from tyres, doors and stored loads. Both start in the jacket.
- Coil in wide loops, walk twists out, and route the cable out of the tyre path and away from door jambs.
- Look along the cable before a session: cuts, flat spots or a section that holds a bend mean stop.
- A damaged cable is replaced, never taped or repaired at home — on this unit it is a manufacturer support case.
How Kinks Happen
A kink is a bend the cable was forced into and kept. It rarely happens during charging; it happens in the thirty seconds of putting the cable away. Tight loops wound small to fit a bag or a boot, a cable yanked around a corner or a gate post, a coil wound the same way every time so the cable slowly takes a twist — each concentrates the bend in one short section. A section that stays bent when the rest hangs straight is the cable saying it was stored too tight.
The prevention is practice, not a specification: coil in wide, loose loops — the kind you can slip a forearm through — let any twist walk out along the cable’s length, and never force the last length into a smaller space. At the unit and connector ends, give it a gentle curve: those ends flex on every session.
How Crush Damage Happens
| Damage mode | Where it usually happens | The habit that prevents it |
|---|---|---|
| Crush | Cable across the driveway, inside the tyre line | Park so the run stays out of the tyre path; route along the wall or overhead |
| Pinch | Garage door closing on the cable, door jamb | Never let a door rest on the cable; at a threshold, use a purpose-made cable ramp |
| Point load | Bins or toolboxes sitting on a coiled cable | Store the coil on a hook or shelf, nothing stacked on it |
| Kink | Tight coiling for travel, cable forced around corners | Wide loops, twists walked out, gentle curves at both ends |
The driveway run is the classic: a cable lying across the drive sits exactly where tyres go. Our verdict on whether you can drive over a charging cable is no — and prevention matters because crush damage can be internal: the jacket can look intact over flattened conductors.

The Ten-Second Look
Prevention has a partner: a quick look along the cable before each session. Look for cuts or nicks in the jacket, a flat or soft spot where the cable was pressed, a section that holds a bend, and damage near the ends, where the cable flexes most. Find any of those and the session does not start — that cable is done until the manufacturer advises otherwise. Whether a cable can be left outdoors between sessions is covered in leaving an EV charging cable outside.
The Cable on This Unit
The EV-ACS3210T is a sealed portable unit — 32 A, about 7.7 kW, NACS connector, IP66 housing — so its cable is not a part you splice. Damage routes to EVDANCE support, not to a workbench: the standard warranty is 3 years, and a crushed or kink-damaged cable is a support conversation, not a repair project.
Frequently Asked Questions
Can I tape over a nick in the cable jacket?
No. Tape cannot restore insulation or the seal against water, and it hides damage from the next inspection. Stop using the cable and contact the manufacturer.
My cable has a permanent bend but the jacket looks intact. Is it safe?
A set bend means the cable was coiled or routed too tight — a handling warning, not proof of internal damage. Inspect that section for cracking or flattening; if you find either, stop. If the jacket is genuinely intact, correct the coiling habit — and if in any doubt, ask the manufacturer first.
Can I drive over the cable just once, slowly?
No. Crush damage needs neither speed nor repetition — one pass can flatten conductors inside an unbroken jacket, where you cannot see it. Route the cable out of the tyre path instead.
