Magicalmai Inductive Hour Meter for Engines & Generators, 2-Pack Red — LCD, IP68 Waterproof

Magicalmai inductive hour meter is a compact, battery-backed LCD gauge that records total run-hours for gas engines and generators without wiring to power.

Keeping track of runtime is the simplest way to schedule oil changes, tune-ups and other preventive maintenance for motorcycles, lawn mowers, ATVs, generators and small marine engines. The Magicalmai inductive hour meter mounts near the engine and senses ignition pulses on the spark plug wire, logging hours to 0.1 resolution on a clear LCD. Because it stores accumulated time in solid state memory and uses an internal long-life battery, readings remain visible even when the engine is off.

How does this hour meter install and start recording?

Installation is straightforward and doesn’t require cutting into your electrical system. The meter uses an inductive pickup: clamp the included wire around the spark plug lead and secure the small module to your engine or frame with the supplied screws or adhesive strips.

• Clip the inductive wire to the spark plug cable—no splicing needed
• Choose screw-mount or peel-and-stick using the extra adhesive strips
• 110 cm (43 in) lead gives flexible placement options
• LCD begins counting automatically when ignition pulses are detected

What information does the display provide and how durable is it?

The LCD shows accumulated run-hours to a maximum of 9,999.9 hours with 0.1-hour resolution. The unit is epoxy-encapsulated, rated IP68 for waterproofing, and designed to resist shock and high temperatures, so it stands up to outdoor and engine-bay conditions.

• Large, readable LCD keeps the reading visible even when powered down
• Counts in 0.1-hour increments and displays an hourglass icon when running
• IP68 waterproofing and epoxy sealing protect electronics from moisture and vibration
• Operating range approximately −30°C to 85°C for varied climates

Will the meter lose data or need frequent battery changes?

No external power is required to run the counter; the inductive pickup senses engine ignition and the internal battery retains the total hours. The sealed battery is rated for long service life, and the total accumulated hours cannot be reset, ensuring an accurate maintenance history for the machine.

• Internal sealed battery stores totals for up to about 10 years
• No clicking mechanical parts—solid-state reliability
• Non-resettable display preserves full run-hour history
• Standby time supports long-term storage between uses

Who is this for: Mechanics, fleet owners, landscapers, small-boat operators, and DIYers who need a reliable, low-cost way to monitor runtime and plan service intervals will find the Magicalmai inductive hour meter useful. It’s especially practical for any gas-powered equipment where maintenance is scheduled by hours rather than mileage—lawn tractors, portable generators, dirt bikes, ATVs, snowmobiles, and marine outboards are all good matches. The 2-piece red kit provides a spare or lets you monitor two machines, and the mix of screw and adhesive mounting options works when space or access is limited.
