The things that keep a long drive comfortable, powered and prepared for the unexpected.
A road trip goes wrong in small ways: a phone that dies halfway through the navigation, nothing to drink, a stop that costs an hour because nobody packed food. Almost all of it is preventable with a handful of items kept within reach rather than in the boot.
Below: what belongs in the cabin, what makes the hours pass comfortably, and the just-in-case items worth carrying even on a familiar route.
In the car

Keep these within arm's reach of the front seats.
Phone mount
Navigation you can glance at, rather than hold, is the single biggest safety upgrade in a car you are driving all day.
Why you need it. Navigation you can glance at, rather than hold, is the single biggest safety upgrade in a car you are driving all day.
What to look for. A vent or windscreen mount that holds your phone in its case, positioned so it never blocks your view of the road.
Car charger
Navigation, music and hands-free calling drain a phone faster than it charges from an old USB socket.
Why you need it. Navigation, music and hands-free calling drain a phone faster than it charges from an old USB socket.
What to look for. A charger that can fast-charge two devices at once, with a cable long enough to reach the back seats.
Power bank
Keeps a phone, GPS watch or headlamp alive on long days, and cold weather drains batteries much faster than you expect.
Why you need it. Keeps a phone, GPS watch or headlamp alive on long days, and cold weather drains batteries much faster than you expect.
What to look for. A 10,000 mAh unit is a sensible balance of capacity and weight for most trips. Bring the right cable — the bank alone is useless.
Water bottle
Dehydration is the quiet reason most days out start to feel hard. Carrying your own water means you never depend on finding a tap.

What to look for. Around 1 litre per person for a half-day, easy to drink from one-handed, and a shape that fits your pack's side pocket.
Snack box
Food you brought is cheaper, faster and better than whatever the last service station has left, and it keeps everyone level-headed.

What to look for. A sealable box of things that survive warmth — nuts, dried fruit, crackers. Keep it within reach, not in the boot.
Comfort
0 of 4
What makes hour six feel like hour two.
Travel pillow
Whoever is not driving should be able to sleep properly, which matters even more if you plan to swap drivers.
Why you need it. Whoever is not driving should be able to sleep properly, which matters even more if you plan to swap drivers.
What to look for. A supportive neck pillow that compresses small. Memory foam holds shape; inflatable takes almost no space.
Sunglasses
Glare off water, pale rock and snow is tiring and, high up, genuinely uncomfortable for hours afterwards.

What to look for. Full UV protection and a wrap that keeps light out at the sides. A retaining cord saves them on windy ridges.
Reusable cup
Coffee stops are half the point of a road trip, and a lidded cup means no spills on the next stretch.

What to look for. A leak-proof insulated cup that fits your car's cup holder — measure before you buy.
Window sun shade
Low sun through side windows is uncomfortable for hours and unbearable for children or dogs in the back.
Why you need it. Low sun through side windows is uncomfortable for hours and unbearable for children or dogs in the back.
What to look for. Static-cling or frame shades sized to your rear windows. Never fit anything that obstructs the driver's view.
Just in case

Rarely used, extremely welcome when needed.
First aid kit
Blisters, grazes and headaches are the everyday injuries, and all of them are far more manageable with a small kit in the bag.
Why you need it. Blisters, grazes and headaches are the everyday injuries, and all of them are far more manageable with a small kit in the bag.
What to look for. Blister plasters, adhesive dressings, antiseptic wipes, painkillers and a bandage. Restock it after every trip rather than before the next one.
Jumper cables
A flat battery in an unfamiliar place is the most common way a trip stalls, and it is entirely fixable with help nearby.
Why you need it. A flat battery in an unfamiliar place is the most common way a trip stalls, and it is entirely fixable with help nearby.
What to look for. Heavy-gauge cables long enough to reach between two cars parked nose-to-nose, or a self-contained jump starter.
Tyre inflator
Correct pressures improve grip and fuel use, and a slow puncture becomes manageable rather than trip-ending.
Why you need it. Correct pressures improve grip and fuel use, and a slow puncture becomes manageable rather than trip-ending.
What to look for. A 12 V compressor with a clear gauge and automatic stop. Learn your car's recommended pressures before you go.
Warning triangle and hi-vis vest
If you have to stop on a road, being seen early is what keeps you safe — and in many countries it is a legal requirement.
Why you need it. If you have to stop on a road, being seen early is what keeps you safe — and in many countries it is a legal requirement.
What to look for. Check the rules for every country on your route; some require two triangles, a vest per occupant, or spare bulbs.
