DarkBrown Medium Smart Watch for Daily Tracking

The allentian E400 is a wearable device designed for men and women who want continuous health monitoring on Android or iOS. It combines a round aluminium case with a sporty silicone strap and a touch-plus-button interface. The medium 29-35mm diameter suits a range of wrist sizes for all-day wear.

15 to 21 Day Battery Life with Magnetic Charging

A single charge delivers 15-21 days of operation, covering multiple weeks of step counting, heart-rate, blood-pressure, blood-oxygen, body-temperature and sleep tracking between top-ups. Magnetic charging simplifies the process, though heavy use of Bluetooth calling or the remote selfie function will reduce the upper end of that range.

Box Includes Watch, Cable, Manual and Packaging

The package supplies the smart watch, a magnetic data cable, an instruction manual and a box — no extra straps or charging adapters are provided. The bundled cable is the sole means to recharge, so losing it pauses all monitoring until a replacement is sourced.

Questions about this item

Will the 29-35mm aluminium case fit comfortably alongside a traditional watch strap I already own?

The case diameter is 29-35mm and the strap is silicone, so it sits flat against the wrist without interfering with a separate band worn on the other arm.

How can I confirm the heart-rate and blood-oxygen sensors are reading correctly after the first charge?

Compare the on-screen heart-rate and blood-oxygen values with a clinical pulse oximeter at rest; consistent readings indicate the sensors are working as intended.

Does the package include a power adapter or only the magnetic charging cable?

The box contains the E400 watch, a magnetic data cable, an instruction manual and the retail box; a USB power adapter is not included and must be sourced separately.
