Car gear, measured. Every figure names the lab that measured it and the conditions it was measured under.https://cargearbench.com/en-ushttps://cargearbench.com/repair-tools/jack-stands/https://cargearbench.com/repair-tools/jack-stands/More than 1.7 million jack stands were recalled after they were found able to collapse under load. The cause was production tooling wearing out — same item number, same rating, safe early and unsafe later.Sat, 01 Aug 2026 00:00:00 GMThttps://cargearbench.com/tyres/performance-summer/https://cargearbench.com/tyres/performance-summer/Eight tyres, one size, one car. The wet braking spread is 6.94 m — at the point the best has stopped, the worst is still doing 38 km/h. And the tyre that finished last is joint best on rolling resistance.Sat, 01 Aug 2026 00:00:00 GMThttps://cargearbench.com/accessories/jump-starters/https://cargearbench.com/accessories/jump-starters/Peak amperage lasts 20 to 50 milliseconds. Cold cranking amps is sustained for 30 seconds, and it is what your battery is rated in — and the two units advertising the highest peak publish no CCA at all.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/accessories/magsafe-car-mounts/https://cargearbench.com/accessories/magsafe-car-mounts/The highest-ranking test of magnetic car mounts is written by a mount manufacturer and contains no hold-strength figure in any unit. What can actually be checked: magnet type, vent geometry and charging wattage.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/accessories/tire-inflators/https://cargearbench.com/accessories/tire-inflators/Six inflators timed from 10 psi on one 245/50R20. The spread is a factor of four — and the time-to-30-psi figure everyone quotes flatters the small pumps, because they lose more in the second half.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/dash-cams/night-plate-legibility/https://cargearbench.com/dash-cams/night-plate-legibility/Nine dash cams, one number plate, measured in feet by day and by night. The best managed 30 ft after dark — and a 4K camera failed where a 1440p camera succeeded.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/dash-cams/parking-mode/https://cargearbench.com/dash-cams/parking-mode/Parking mode is the most advertised dash cam feature and the least measured. What the pre-impact buffer does, why the 12V socket will not run it, and what six cameras claim — all marked as manufacturer figures, because that is all that exists.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/detailing/car-vacuums/https://cargearbench.com/detailing/car-vacuums/Car and Driver prints suction in inches of water, MotorTrend in kilopascals, and neither converts. Put on one scale, ten vacuums measured — and on the one machine both tested, the two labs agree to 0.01 kPa.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/detailing/dual-action-polisher-beginners/https://cargearbench.com/detailing/dual-action-polisher-beginners/Which DA polisher to buy first, decided on the two things anyone has actually measured — how heavy it is and how loud it is — with every figure sourced and the manufacturer's claims marked as claims.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/detailing/pressure-washer-car/https://cargearbench.com/detailing/pressure-washer-car/Every pressure washer is sold on a psi number the manufacturer supplies. The one published test that put a gauge on the line read 1000 psi through a car-washing nozzle. What to buy, and why flow matters more than pressure.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/ev-charging/amps-you-can-actually-use/https://cargearbench.com/ev-charging/amps-you-can-actually-use/A 48-amp charger needs a 60-amp breaker, and your car may cap the rate anyway. Work out the charging speed your panel and your car will really give you, with a calculator and the arithmetic shown.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/problems/car-wont-start-clicking/https://cargearbench.com/problems/car-wont-start-clicking/Rapid clicking and a single click mean different things. But the measurement that settles it is the voltage while cranking — a battery can read a healthy 12.6 V at rest and still collapse below 9.6 V under the starter.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/problems/tpms-light-cold-weather/https://cargearbench.com/problems/tpms-light-cold-weather/Cold costs about 1 psi per 10 °F. The warning lamp is required to light at 25 per cent below placard — about 9 psi. Temperature alone cannot do that, so the lamp means the tyre was already low.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/repair-tools/obd2-scanners/https://cargearbench.com/repair-tools/obd2-scanners/Across a 22× price range the number of live data channels barely moves — the correlation is +0.16, and the unit reading the most costs $50. What you actually pay for is bidirectional control.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/repair-tools/torque-wrenches/https://cargearbench.com/repair-tools/torque-wrenches/A click wrench is certified to ±4 per cent, and only over the upper part of its scale. A 1/2 in drive wrench is out of specification below about 40 N·m — which is most of what strips.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/tools/dilution-calculator/https://cargearbench.com/tools/dilution-calculator/Work out how much concentrate goes into a 16, 22, 24 or 32 oz bottle at any dilution ratio. Shows both readings of a ratio, because brands do not agree on what 1:10 means.Fri, 31 Jul 2026 00:00:00 GMThttps://cargearbench.com/tools/inflation-time-calculator/https://cargearbench.com/tools/inflation-time-calculator/Published inflator times are measured on one tyre. Scale them to yours: enter your tyre size and get the time each measured inflator would take, with the arithmetic shown.Fri, 31 Jul 2026 00:00:00 GMT
