SLEVIO Portable Gym Workout Timer, Black, Large LED Display and Magnetic Rubber Case

The SLEVIO Portable Gym Workout Timer is a compact, magnetic LED fitness clock with a rubberized case designed for interval training, stopwatch use, alarms and clear outdoor visibility.

Whether you train in a home garage, at a park, in school gyms, or travel with a compact setup, this timer centralizes your session control without needing a phone. It combines multiple timing modes—intervals, countdowns, count-ups, alarms and a buzzer—with a built-in magnetic spine and anti-glare display. Lightweight and pocketable, the unit is built for repeated use with up to 30 hours of battery life per charge and a low-battery reminder so workouts stay uninterrupted.

How does this timer simplify interval training?

The SLEVIO timer gives you preset and custom interval options so you can run Tabata, HIIT, CrossFit or EMOM formats without fumbling with apps. It supports three custom groups for different interval setups, plus round-based count up and countdown modes to match complex session structures.

• Three customizable interval groups for varied workouts
• Count-up and count-down-by-round modes for EMOM and circuits
• Ten-second countdown and buzzer control to cue transitions
• Simple front-facing controls to switch modes quickly during sets

How portable and durable is the SLEVIO fitness clock?

This timer measures roughly 6.9 × 2.3 × 0.98 inches—small enough to fit into a pocket or small bag—and is wrapped in a non-slip rubber case that resists drops and sweat. A recessed magnetic spine embeds into the case so you can attach the timer to any steel surface, keeping it visible and stable throughout intense movement.

• Pocket-size form factor for easy transport
• Non-slip rubber exterior for grip and impact protection
• 0.8 × 1.6-inch built-in magnet for secure mounting on metal
• Robust enough for garages, parks, and busy training spaces

Will I be able to read the display outdoors or from across the room?

The large LED digits and an anti-glare lens improve visibility under bright sunlight and in gym lighting, so you can check time at a glance without interrupting your set. The high-contrast screen reduces squinting and helps maintain pace even during fast transitions.

• Large LED display for quick readability
• Anti-glare lens designed for outdoor visibility
• Clear numeric contrast for viewing from a distance
• Adjustable buzzer to alert transitions without needing to look constantly

How long does the battery last and how will I know when to recharge?

SLEVIO's rechargeable battery can power the timer for up to 30 hours on a single charge, which covers multiple sessions or a full weekend of classes. An automatic low-battery reminder notifies you in advance so you can charge the unit before a workout begins.

• Up to 30 hours of runtime per charge
• Low-battery reminder to prevent mid-session shutdown
• Efficient power draw for extended use between charges
• USB-rechargeable for convenient top-ups

Who is this for? If you want a rugged, easy-to-see timer that frees you from relying on a phone during workouts, the SLEVIO Portable Gym Workout Timer is designed for athletes, coaches, personal trainers, school PE programs and home-gym users. It especially suits people who need quick mode changes, a strong magnetic mount for hands-free viewing, and reliable battery life for back-to-back classes or outdoor sessions. SLEVIO aims to keep timing straightforward so you can focus on performance rather than setup.
