Why winter is breakdown season
Car batteries hate the cold. A battery that cranked happily through summer can lose a large chunk of its output once overnight temperatures drop toward zero, which is why roadside assistance callouts climb every June through August.
Winter also stacks the odds against you in other ways: shorter days mean you're more likely to be stranded in the dark, and wet roads mean more minor bumps and more time waiting on the shoulder. A breakdown kit isn't about pessimism — it's about making the bad day short.
The one item that gets you home: a jump starter
Decades ago, a flat battery meant flagging down a stranger with jumper leads. A modern lithium jump starter ends that entirely — it lives in your glovebox, weighs about as much as a paperback, and starts your car on its own.

Lithium jump starters slowly self-discharge. Top yours up every two to three months — a quick charge while you watch TV — so it's ready the one morning you actually need it.
Light to work by — and to be seen by
Almost every roadside fix is harder than it should be because you can't see what you're doing. Your phone torch is a poor substitute: you need one hand to hold it, and it throws a narrow beam exactly where your shadow falls.

If you're waiting an hour or two for roadside assistance in a regional area, your phone is your lifeline — and cold weather drains phone batteries noticeably faster. A proper power station goes a step beyond a pocket power bank, running lights, laptops and camping gear as well as keeping every phone in the car charged.

Winter's wet roads mean more low-speed bumps, and in any dispute the driver with footage wins. A dash cam is the quiet member of your emergency kit: it does nothing 364 days a year, then earns its price in one afternoon.

The whole kit — jump starter, two lights, power station, dash cam and umbrella — fits in one small boot organiser and needs about ten minutes of attention a year. That's a fair trade for never being truly stranded.

Frequently Asked Questions
1. What should a basic car breakdown kit include?
A jump starter, a hands-free light, a charged power bank or power station, water, a warm layer and a rain jacket or umbrella cover the vast majority of roadside situations.
2. Can a portable jump starter really start my car?
Yes — a 600A lithium jump starter will start most petrol and diesel passenger vehicles. Connect it to the battery terminals, wait for the ready light and start the car as normal.
3. Why do car batteries go flat more often in winter?
Cold slows the chemical reaction inside the battery, cutting its cranking power at exactly the time the engine needs more of it. Older batteries that coped in summer often fail on the first cold morning.
4. Where should I store my breakdown kit?
Keep the jump starter in the glovebox or centre console where it stays closer to cabin temperature, and the rest in a small organiser in the boot so it doesn't slide around.
