The best car accessories, one buying guide at a time

Choose between a ready-to-charge handheld, a pet-focused kit, a garage wet/dry vacuum and a bare tool that uses batteries you already own.

Compare traditional liquid wax, a cleaner wax and ceramic spray protectants. Choose around paint condition, preparation and the application routine you prefer.

Pick shampoo around your existing paint protection and wash method. Compare conventional wash formulas, coating-focused cleaning and a wash-and-wax option.

Eight portable compressors, one per job: the unit that runs off the lighter socket, the cordless one that actually gets used, the off-road workhorse, and the kit that seals a puncture.

Nine tools, from a reader that tells you why the light is on to a bidirectional tablet that can command a module and watch it answer.

Pick a gauge with the right pressure range and a head you can reach the valve with. Compare digital readouts, battery-free dials and pocket backups.

Choose the wrench after looking up the fastener specification. Compare drive size, working range and measuring direction instead of buying the biggest tool.

Eight lithium packs and one professional lead-acid unit, sorted by the engine each one has to turn over rather than by the peak-amp number on the box.

Four home chargers, a portable, and the adapters that decide which public stations your car can actually use — judged on certification and amperage before anything else.

Choose a charger around the battery label, available AC power and whether you need a storage maintainer or a higher-current charging tool.

Choose a compressor fridge around cargo space, food storage needs and the power available while parked. Separate dual-zone storage from a single compartment.

Separate stored energy from outlet power, then choose the connectors your devices require. Includes the important Anker C300 vs C300 DC distinction.

Eight cameras sorted by what has to be recorded: the road ahead, the road behind, the cabin as well, and whatever happens while the car is parked.

Match the holder to your phone case and the mounting surface first. Then decide whether you need a simple cradle or wireless charging.

Find an adapter for existing wired CarPlay or Android Auto. Compare iPhone-only models with dual-platform choices and check the factory system first.
