How To Choose The Best Automotive Accessories
Automotive accessories cover a wide range, from protecting your interior to rescuing you from a breakdown. The key is to match the product’s core specs — material, size, power source, and compatibility — to your specific vehicle and your daily driving habits.
Start with your biggest pain point
Do you park in direct sun every day? A sunshade with a reflective silver coating and 240T polyester (a tightly woven fabric, 240 threads per inch) handles extreme heat and keeps your dashboard from baking. Are your headlights so foggy you struggle to see at night? A ceramic restoration kit eliminates the need for costly headlight replacements. If you often haul messy gear, weatherproof floor mats with raised edges contain slush and mud before they stain the carpet.
Check the dimensions and fit
Not every product labeled “universal” actually fits your vehicle well. A seat gap filler that is 17.95 x 5.04 x 2.6 inches might feel bulky in a compact car, while a pair of floor mats measuring 27 inches long by 20 inches wide may need trimming to contour the footwell of a sedan. Always verify the listed dimensions against your car’s interior.
Power and connectivity matter for electronic gear
A tire inflator that runs on a 12V DC cigarette lighter plug (the standard car-lighter socket) needs the vehicle to be running to deliver full pressure. An OBD2 scanner (a diagnostic tool that reads your car’s computer) draws power directly from the Data Link Connector under the dash — no batteries required. For jumper cables, the gauge (thickness of the wire) and length determine how easily they reach across two vehicles in a tight parking lot, so number plates stay visible and the connection is easy.
Consider how easy it is to store
Many of these accessories live in your trunk or glove box. A compact inflator that weighs 1 kilogram and measures 6.8 by 3.9 inches fits under a seat, while 16-foot jumper cables coiled inside a carry bag take up noticeable trunk space. Think about where each item will ride before you buy.

In‑Depth Reviews
1. Drop Stop Car Seat Gap Filler (Patented, Set of 2)
This Shark Tank original blocks the entire seat gap so phones and keys stay on the seat instead of falling into the abyss.
Drop Stop covers 100% of the gap — in front of, around, and behind the seat belt catch (the buckle that clips in). It is not just a thin strip that leaves a hole underneath. It attaches through a built-in slot on the belt catch, so it moves with the seat and never needs readjustment after installation.
At 17.95 x 5.04 x 2.6 inches, this filler is noticeably larger than the CERAKOTE kit (which weighs just 4.8 ounces compared to Drop Stop’s 11.2 ounces). The high-grade neoprene (a stretchy, durable synthetic rubber) expands or contracts to fit whatever gap your seat leaves, and the dark color blends in so well you barely notice it is there. Each package includes two units (driver and passenger side) plus a Slide Free Pad and an LED Credit Card Light as bonus items.
Buyers report the fit is very tight and the filler can pop out when the seat moves forward or back a lot. For most vehicles it stays planted, but if you adjust your seat frequently you may need to push it back into place now and then.
Gap filler stops drops
- Covers 100% of the gap — front, side, and behind the belt catch
- Moves with the seat; no reinstallation needed
- Includes bonus Slide Free Pad and LED Credit Card Light
May shift over time
- Very tight fit can be hard to insert initially
- May pop out when the seat is adjusted aggressively
For messy drivers: you are tired of fishing phones, keys, and coins out of the abyss between your seat and console, and you want a set-it-and-forget solution.
If seats are tight: you slide your seat forward and back multiple times per day — the constant movement may dislodge it.
2. ANCEL AD310 OBD2 Scanner
This best-selling code reader shows you exactly why that check-engine light is on, without the mechanic’s labor bill.
It supports all OBDII protocols (standards for talking to your car’s computer) including KWP2000, J1850 VPW, ISO9141, J1850 PWM, and CAN (Controller Area Network, the modern standard). That means it works with 1996 or newer US-based vehicles as well as 2000 or newer European and Asian cars. The display resolution is 128×64, which makes the readouts crisp and easy to scan at a glance.
Unlike some budget readers that only show a code number, the AD310 reads live data (real-time sensor readings) and hard memory data (permanent fault records), shows a freeze frame (a snapshot of engine conditions when the fault occurred), and checks I/M monitor readiness (emission system status). It weighs just 12 ounces and its compact design (8.9 x 6.9 x 1.4 inches) slides into a glove box easily. It draws power directly from the OBDII Data Link Connector (the diagnostic port under your dashboard), so you never need to charge it or buy batteries — just plug it in and go.
The one limit worth noting: this scanner only diagnoses emission-related issues. If a fault is unrelated to the emissions system, it cannot read that code. For most daily driver problems like a loose gas cap or a failing oxygen sensor, it handles them perfectly.
Smooth OBD2 diagnostics
- Supports all major OBDII protocols including CAN
- Reads live data, freeze frame, and I/M readiness
- Compact and light — easy to store in the glove box
Limited advanced features
- Only reads emission-related codes; some engine faults are skipped
For basic code reads: you want to diagnose your own check-engine light without guessing and save a trip to the shop.
If you need live data: you need a full-system scan that includes non-emission faults like transmission or ABS codes (Anti-lock Braking System).
3. EcoNour Windshield Sunshade (Medium 64×32 in)
Stops your car from becoming an oven during the summer workday, using a 240-thread-count silver-coated fabric.
Made from 240T polyester (a tightly woven fabric, 240 threads per inch) with a silver coating, this sunshade reflects UV rays and keeps the dashboard, seats, and steering wheel from baking. The medium size measures 64 by 32 inches and has an expandable overlap up to 8 inches for a secure fit across a range of small sedans, hatchbacks, and mini SUVs.
Owners mention it “keeps interior cool after 8+ hours in 90°F California sun” — a real-world test that lines up with the polyester’s heat-reflecting performance. The shade pops open instantly, installs in seconds, and folds back into the included storage pouch when you are on the move. Unlike the Drop Stop which solves a physical gap, this solves a temperature problem, and it does so at a budget-friendly price point that still feels well-made.
Refolding the shade is stiff and awkward at first, and it takes a few tries to get the hang of it in a confined cabin space. The material feels durable, but only time will tell how many seasons it lasts through extreme heat.
Blocks glare effectively
- 240T polyester with silver coating blocks UV rays effectively
- Expandable overlap up to 8 inches for a snug fit
- Folds into storage pouch; easy to stow when not in use
Fits only medium dashboards
- Refolding is stiff and awkward in a small cabin
- Long-term durability in extreme heat is uncertain
For sunny commutes: you park outside in sunny climates and want a simple, affordable way to keep your interior cool and protect electronics like dash cams or phones from heat damage.
If you have a truck: you need a perfect fit for an unusually shaped windshield or a heavy-duty shade that survives daily folding year-round.
4. AstroAI AIRUN Tire Inflator (12V DC)
You set your target pressure, and this compact pump shuts itself off automatically — no more crouching to check a manual gauge.
With this inflator you set the desired pressure using the “+” and “-” buttons, and the unit automatically shuts off when it reaches that number. The digital screen shows four pressure unit options, so you can work in PSI (pounds per square inch), BAR (metric pressure unit), kPa (kilopascals), or kg/cm² (kilograms per square centimeter) depending on your preference. It runs on a 12V DC cigarette lighter plug, so keep the vehicle running during use.
Customers note it fills a tire in under a minute and stays reliable after years of use. At 6.8 x 3.9 x 8.4 inches and weighing just 1 kilogram (2.2 pounds), this is compact enough to store under a seat or in a crowded trunk — unlike the Energizer jumper cables which weigh 4.66 pounds and take up more space coiled in their bag. The 9.8-foot cord reaches the rear tires of most regular-sized vehicles, though reviewers point out large cars may require leaving a back door open to reach the far side.
The built-in flashlight is useful but dim, so do not rely on it as a primary work light. Some users also mention the lack of printed instructions makes setup a minor guessing game the first time.
Fast tire inflation
- Programmable auto shut-off means you walk away while it inflates
- Compact enough to store under a seat or in a glove box
- 9.8-foot cord reaches most rear tires without repositioning the car
Noisy during operation
- Flashlight is dim; not great for nighttime work
- No printed instructions in the box
For emergency top-ups: you want a low-maintenance tire pump that saves you from over-inflating and fits anywhere.
If you need quiet use: you need a super-bright work light integrated into the pump or want a unit with detailed printed instructions.
5. CERAKOTE Ceramic Headlight Restoration Kit
Three easy wipes turn cloudy headlights back to clear without needing a drill or buffer — and the ceramic coating bonds for long-lasting protection.
This kit contains 8 Step 1 Oxidation Removing Wipes, a Step 2 Sanding Kit, and 2 Step 3 Ceramic Coating Wipes. You do not need any power tools — everything is hand-applied. The ceramic coating (a liquid glass-like layer) chemically bonds to the headlight lens and provides UV protection that, according to the manufacturer, lasts as long as you own the vehicle. Buyers confirm the results hold up well, with one reviewer reporting it “lasts over 2 years in Texas sun/heat.”
Weighing just 4.8 ounces, this is the lightest accessory in the lineup — more than twice as light as the Drop Stop filler (11.2 ounces). The entire process takes about 30 minutes and dramatically improves nighttime visibility, making road signs and hazards easier to see. For vehicles with deeply pitted or severely yellowed lenses, the sanding step is critical; skipping or rushing it leaves a hazy finish. Some buyers also mention that splitting the kit’s supplies lets you restore two cars with a single purchase.
The kit works on brake lights and fog lights in addition to headlights, making it a versatile tool for freshening up the whole rear of the car.
Restores clarity quickly
- Ceramic coating bonds chemically for long-lasting UV protection
- No power tools means zero risk of burning through paint
- Works on headlights, brake lights, and fog lights
Needs careful application
- Sanding step is critical — missed spots leave a hazy finish
- Deeply pitted lenses may need a more aggressive wet-sanding before the kit can fully restore them
For foggy lenses: your headlights are foggy or yellowed but not deeply scratched, and you want a no-fuss restoration that lasts for years.
If lenses are deeply scratched: your lenses have deep physical pitting or rock chips that need wet-sanding (using wet sandpaper) before a ceramic coating can adhere properly.
6. Energizer Jumper Cables (16-Foot, 6-Gauge)
16 feet of cable lets you reach from a van in a tight spot to a stranded BMW, even in sub-zero temperatures.
These 6-gauge (a thick wire, lower number = thicker copper) copper-clad aluminum cables stay flexible even at -40°C (-40°F), which matters when you need a jump in bitter cold. The 16-foot length gives you room to park vehicle-to-vehicle without bumper-to-bumper alignment — shoppers say they “successfully jump-started a V8 BMW from a V6 van after 10 min charge” using the extra reach to connect garage-to-driveway. The thick vinyl coating resists rust and corrosion, and the strong spring clamps have good teeth that bite into the battery terminals.
At 3.11 x 10.87 x 11.02 inches, this storage footprint is noticeably larger than most other accessories — it is 5.8 times the volume of the Drop Stop drop stop. The included carry bag keeps the cables tidy, but buyers report the bag itself is not super sturdy. The cables coil up neatly inside, though the bag’s zipper and stitching feel like the weakest link on an otherwise solid product.
For most cars, a 6-gauge cable is more than enough. If you drive a heavy-duty diesel truck with a massive battery, you might prefer a thicker gauge (like 4-gauge or 2-gauge), but for everyday cars, SUVs, and full-size sedans, this is the right balance of heft and flexibility.
Long cables for reach
- 16-foot length reaches awkward parking positions easily
- 6-gauge copper-clad aluminum handles cold starts in freezing temps
- Thick vinyl coating protects against rust and corrosion
Heavy to store
- Carry bag is not very sturdy; zipper and stitching feel flimsy
For dead batteries: you want a set of emergency cables that reach across tight parking lots and handle cold-weather jumps without cracking.
If you need compact storage: you need a more rugged storage case or you drive a heavy-duty diesel that requires a thicker 4-gauge or 2-gauge cable.
7. Motor Trend FlexTough Floor Mats (Black)
Universal rubber mats you trim to shape, with raised edges that trap slush and mud before they reach the carpet.
These floor mats are made from a proprietary rubber blend (a custom formula) that stays flexible without cracking or deforming over time. The front pair measures 27 inches long by 20 inches wide at a thickness of 1 inch, while the rear liner spans 51 inches long by 14 inches wide. The raised edges catch spills, slush, and dirt before they reach the carpet underneath. When they get grimy, a simple rinse with soap and water brings them back to new.
At 6 pounds, this is the heaviest accessory in the roundup, but that weight comes from thick, durable rubber that stays planted on the carpet. Unlike the high-end custom-fit liners that snap into specific models, these universal mats rely on a trim-to-fit design — you cut the outer edge to match your vehicle’s footwell shape. Owners mention that on some models like a 2013 Honda CR-V the fit is perfect without any trimming, while on a 2010 Sonata the rear mat needed a simple trim around the raised middle section. They are great for light use like dust and dirt, but customers note they may fall short in heavy mud or deep snow if not trimmed precisely.
The 1-year limited warranty covers defects but voids if the mats are misused or improperly installed. Given the price point, these deliver solid protection for daily driving while staying affordable.
Durable rubber protection
- Thick rubber blend resists deforming and cracking
- Raised edges contain spills and slush before they reach the carpet
- Trim-to-fit design adapts to most vehicles
May curl at edges
- Not as precise as custom-fit liners; may need trimming
- Less suited for heavy mud or deep snow without a perfect trim
For muddy boots: you want an affordable, durable set of all-weather mats that you can cut to fit your car and that clean up with a hose.
If you want carpet feel: you need exact laser-measured coverage for a vehicle with complex footwell contours or if you regularly drive through deep mud and snow.
Understanding the Specs
Gauge and Length in Jumper Cables
The gauge (thickness) of a jumper cable determines how much current it can carry — lower numbers mean thicker copper and more starting power for big engines. 6-gauge is strong enough for most cars, SUVs, and light trucks. Length matters too: 16 feet gives you flexibility to park nose-to-nose or side-by-side, so number plates stay visible and the connection is easy, while shorter cables may force you to reposition the cars.
220T vs 240T Polyester in Sunshades
The “T” number (thread count, the number of threads per inch) tells you how tightly the fabric is woven. A 240T polyester shade like the EcoNour blocks more heat and UV rays than lower-count materials. The silver coating reflects sunlight outward, keeping the cabin cooler. An expandable overlap of up to 8 inches helps the shade fit a variety of windshield sizes without leaving gaps that let heat in.
