10 Things Every Man Should Keep in His Car (That Aren't Half-Eaten Protein Bars)

Your glovebox is currently a mass grave for crumpled fast-food receipts, three expired tire pressure gauges, and a visual history of ketchup packet design dating back to 2018. We know this because it’s a universal guy condition. We treat our vehicles like rolling junk drawers until the exact moment a tire blows out on a pitch-black backroad, or the battery dies in a rainstorm, at which point we suddenly remember that "optimism" is not an effective roadside assistance strategy. Having a properly outfitted vehicle isn't about prepping for a zombie apocalypse; it's about avoiding the specific flavor of humiliation that comes with asking a teenager in a Honda Civic for a jump-start. Here are ten genuinely useful, high-grade items that will elevate your trunk from a chaotic storage unit into a tactical mobile command post.

1. NOCO Boost Plus GB40 Lithium Jump Starter

Remember standard jumper cables? The five-foot tangles of copper wire that forced you to pull another car nose-to-nose and awkwardly ask a stranger if they had twenty minutes to spare? The NOCO GB40 makes that whole ritual obsolete. It’s a compact lithium battery pack that delivers 1,000 amps of starting power—enough to jump a 6.0-liter gas engine up to 20 times on a single charge. It fits in your glovebox, won't spark if you connect the clamps backwards, and doubles as a power bank to charge your phone when you're stuck waiting for tow trucks that aren't coming.

WHY WE LIKE IT: It lets you self-rescue from a dead battery without interacting with another human being.

BEST FOR: Anyone whose battery is on its last legs or who parks in sketchy places.

PRICE: $99.95

2. Resqme Car Escape Tool

It’s tiny, weighs less than an ounce, and clips right onto your keychain, but this little piece of molded plastic contains a spring-loaded stainless steel spike capable of shattering tempered side glass with a single push. It also houses a razor-sharp blade designed to slice through jammed seatbelts in seconds. You hope you never have to use it, but keeping one within arm's reach of the driver's seat provides an undeniable sense of tactical security when driving over bridges or along high-speed corridors.

WHY WE LIKE IT: High-impact utility in a package smaller than a house key.

BEST FOR: Daily commuters, road-trippers, and paranoid drivers.

PRICE: $9.95

3. DEWALT 20V MAX Cordless Tire Inflator (DCC020IB)

Gas station air pumps are a nightmare. Half of them are out of order, the rest cost three dollars in quarters, and the hose is always coated in mystery sludge. DEWALT’s portable air inflator runs on standard 20V power tool batteries (or a 12V car plug) and lets you set your desired PSI on a digital display before automatically shutting off when reached. It handles truck tires, sports balls, and mattress rafts without breaking a sweat.

WHY WE LIKE IT: Set-it-and-forget-it pressure accuracy without standing in the freezing cold.

BEST FOR: Guys who already own DEWALT power tools or hate gas station air pumps.

4. Slime Smart Spair Ultra Flat Tire Repair Kit

Changing a tire on the side of a busy highway at night is a dangerous, miserable experience. Slime’s kit offers a temporary, zero-jack alternative: pump the non-toxic sealant directly into your tire valve, use the included 12V inflator to air it back up, and drive away in under ten minutes. It seals punctures up to a quarter-inch wide instantly, giving you enough range to safely reach a tire shop.

WHY WE LIKE IT: Solves a flat tire emergency without requiring you to get on your knees in the dirt.

BEST FOR: Quick roadside fixes when swapping to a spare isn't practical.

PRICE: $62.39

5. Anker 67W Car Charger (PowerDrive Speed)

Low-voltage USB ports built into vehicle dashboards are notoriously slow, often charging your phone at a pace that barely offsets screen usage during navigation. Anker’s high-output 67W charger plugs into your 12V cigarette lighter socket and pushes enough power via USB-C to fast-charge standard smartphones, tablets, and even modern laptops like a MacBook Air directly while driving.

WHY WE LIKE IT: Genuine high-speed charging capability that can handle laptops on the go.

BEST FOR: Road warriors, commuters, and power users who drain batteries fast.

PRICE: Price varies

6. Leatherman Wave Plus Multi-Tool

Carrying a full toolbox in your trunk takes up valuable cargo space, but carrying zero tools is an invitation to bad luck. The Leatherman Wave Plus offers 18 distinct tools—including wire cutters, needle-nose pliers, wood saws, and locking blades—all folded into an all-stainless-steel chassis. From tightening loose battery terminals to opening bottle tops at a tailgate, it handles minor mechanical issues effortless.

WHY WE LIKE IT: Unmatched build quality and practical versatile utility in one hand-sized tool.

BEST FOR: Handymen, outdoor enthusiasts, and fix-it guys.

PRICE: Price varies

7. Streamlight ProTac HL USB Tactical Flashlight

Your smartphone camera light is fine for finding dropped keys under the couch, but it falls completely short when inspecting an engine bay or signaling for help in total darkness. The Streamlight ProTac HL throws 1,000 lumens of neutral white light, features an anodized aluminum body, and recharges via USB directly from your car's power ports.

WHY WE LIKE IT: Blinding output encased in an indestructible aircraft-aluminum body.

BEST FOR: Nighttime driving emergencies and outdoor visibility.

PRICE: Price varies

8. WeatherTech Cargo Liner

Trunks endure relentless abuse from dirty hiking boots, leaking bags of mulch, wet dogs, and groceries. Factory carpet absorbs spills and retains smells indefinitely. WeatherTech’s custom-molded cargo liners feature a raised outer lip that traps dirt, water, and chemical spills before they ruin your interior. When it gets dirty, pull it out, hose it down, and slap it back in.

WHY WE LIKE IT: Industrial-grade carpet protection tailored to your exact vehicle make and model.

BEST FOR: Dog owners, outdoor enthusiasts, and people who care about resale value.

PRICE: Price varies

BUY NOW: Buy on WeatherTech

9. Matador Pocket Blanket 4.0

A full-sized wool or fleece blanket takes up massive trunk space and acts as a magnet for dog hair and dirt. The Matador Pocket Blanket unfolds to seat 2–4 adults comfortably, but repacks down into an integrated pouch smaller than a pack of cards. Made from water-resistant, puncture-resistant material, it provides an instant clean seating surface for spontaneous picnics, beach trips, or working under the car on damp pavement.

WHY WE LIKE IT: Full-sized ground protection that takes up virtually zero storage space.

BEST FOR: Spontaneous picnics, outdoor events, and emergency ground cover.

PRICE: Price varies

10. Yeti Rambler 20 oz Travel Mug

Keeping an empty, ultra-insulated travel mug in your cup holder guarantees you always have a vessel capable of maintaining piping hot coffee or ice-cold water for hours. The Yeti Rambler features double-wall vacuum insulation, a leak-resistant StrongHold lid, and a narrow base designed to fit seamlessly into standard vehicle cup holders without rattling around.

WHY WE LIKE IT: Superior thermal retention and a indestructible build built for daily commuting.

BEST FOR: Coffee drinkers, long-haul commuters, and road-trippers.
