9 useful car gadgets I'd pay full price for (some are on sale now)

Spring savings events like Amazon's Big Spring Sale are nearly here, and it's a handy time to pick up practical gear for warmer months. If road trips are on your calendar, consider outfitting your car with chargers, headrest hooks, jump starters, tire inflators and other useful accessories.

ZDNET testers, including Adrian Kingsley-Hughes and the article's author, have tried many of these items. One simple favorite is a multipack of headrest hooks that slip between the headrest and seat, providing a place to hang purses, bags and other incidentals; the pack comes in more than a dozen colors and costs under $10.

For personal safety, the She's Birdie alarm is designed for keys rather than the car itself. It emits a 130 dB siren and flashes a strobe for up to 40 minutes when the top pin is pulled; the reviewer has carried one for almost seven years and recommends it for students, parents and older adults.
