EV accessories

Accessories actually worth buying for your new EV

Most EV "accessories" on Amazon are junk. These are the few that genuinely change what your car can do — open up the Tesla Supercharger network on a non-Tesla, save a road trip from a charging desert, or get your bricked EV back on the road when the 12V battery dies.

NACS adapters — open up Tesla's network

The single best upgrade for any non-Tesla EV in 2026 is an adapter that lets it use the Tesla Supercharger and Destination Charger networks. The number of available DC fast chargers roughly doubles overnight, and the Tesla network has better uptime than anyone else's by a wide margin.

Many 2025+ models ship with a free NACS adapter from the manufacturer or open the network natively. Check what's already included before buying.

Portable charging — the road-trip insurance

The 120V cord that came with your car can save a stranded trip — slowly. A portable Level 2 cord plugs into any NEMA 14-50 outlet (every RV park has them) and gives you ~25 miles of range per hour instead of 4. Stash it in the frunk and forget about it until you need it.

Dash cams — the sentry gap on non-Tesla EVs

Tesla bundles Sentry Mode and a built-in dashcam (you still supply the USB drive). Almost every other EV ships without one. A dedicated dash cam closes that gap, and the EV-specific thing to look for is a supercapacitor instead of a battery — it shrugs off the cabin-temperature extremes that kill battery-based cams, which matters in a car you'll often leave parked and unplugged in the sun or cold. A parking monitor catches the lot taps and hit-and-runs that are the whole reason to own one.

If your EV already has a built-in dashcam (Tesla, some Rivian/Hyundai trims), you may only want the interior cabin cam — or nothing at all. Buy the gap, not the gadget.

The roadside kit nobody warns you about

Two things every new EV owner gets surprised by eventually:

• EVs cannot be flat-towed. The wheels can't rotate with the car off, or you damage the drivetrain. A flatbed is the only safe option. Most tow truck drivers know this now, but not all — make sure your roadside service does, and keep a tow eyelet accessible.
• The 12V battery still dies. EVs have a regular 12V battery for the electronics (door handles, charge port motor, computer wake-up). When it dies, the car is bricked — you can't get in, can't unlock the charge port, can't tow it. A small lithium jump starter in the frunk is the fix and takes ~30 seconds to use.

What we deliberately don't recommend

• "Smart" Level 2 chargers with monthly subscriptions. The car already schedules charging based on time-of-use rates. The dumb $400 chargers do the same thing as the $800 "smart" ones for L1/L2 home use.
• Battery-extender packs. The math doesn't work — a 2kWh portable pack weighing 40 lbs and costing $1,500 adds 7 miles of range. A portable L2 cord ($250) plugged into any RV outlet adds 25 miles per hour indefinitely. Same problem, way better solution.
• Aftermarket "range-boosting" tires. Marketing. Real efficiency differences come from low-rolling-resistance OEM tires that came with the car. Replace with the same model when they wear out.
