Laser distance meter Xiaomi MJJGCJYD001QW — measurement range 0.05–40 m, built-in rechargeable battery, operating −10–50 °C

The Xiaomi MJJGCJYD001QW laser distance meter is a compact measuring tool designed to deliver quick and accurate distance and area measurements up to 40 m, with a minimum measurable distance of 0.05 m. The device incorporates a built-in rechargeable battery with a typical charging time of 1.66 hours and an automatic power-off function after 3 minutes of inactivity. Rated for operation in ambient temperatures from −10 to 50 °C, the unit is supplied as a handheld instrument suitable for on-site measuring tasks in construction, interior planning and DIY projects.

Advantages

The meter provides fast single-button distance readings with laser precision and supports area calculation for rapid estimation of floor and wall surfaces. Its compact housing and rechargeable battery reduce dependence on disposable cells, while the auto power-off feature conserves battery life between uses. The operating temperature range ensures reliable performance in a variety of indoor and outdoor environments where temperatures fall within −10 to 50 °C.

Suitable for

• Measuring room dimensions for interior planning and furniture layout
• Quick distance checks on construction and renovation sites
• Calculating floor and wall areas for material estimates
• DIY projects requiring precise short- and mid-range measurements

Key specifications

• Measurement range: 0.05–40 m
• Minimum measurement distance: 0.05 m
• Measurement modes: single distance and area calculation
• Power source: built-in rechargeable battery (charging time approx. 1.66 hours)
• Auto power-off after 3 minutes of inactivity
• Operating temperature range: −10 to 50 °C
• Form factor: compact handheld unit suitable for one-handed use

How to use

Point the laser at the target surface and press the measurement button to obtain a distance reading. For area measurements, perform sequential distance measurements as indicated by the device and use the area function to calculate surface size automatically. Recharge the built-in battery using the supplied charging cable until the charging indicator shows a full charge; typical charging takes about 1.66 hours. Allow the device to stabilise to ambient temperature before measuring when moving between environments with large temperature differences to maintain measurement accuracy.

Recommendations

For best results, ensure the target surface reflects the laser adequately; avoid direct sunlight on the target during measurement and maintain steady hand positioning while taking readings. Store and charge the device within the specified operating temperature range and observe the auto power-off to save battery life between measurements.
