Daily fitness tracking

The allentian D18 smart bracelet in medium black delivers core health tracking for everyday users who want step counting, heart-rate monitoring and sleep insights on a colour TFT screen. It pairs with Android or iOS devices over a wireless range of five to ten metres and weighs 60 grams with a silicone sport strap.

Upgrade from basic pedometer

Moving up from a simple step counter adds continuous heart-rate data, sleep-stage estimates and smartphone notifications on the wrist, making the jump worthwhile when you want a single device for activity and alerts. The touch-button interface and life-waterproof rating support daily wear and light splashes.

Seven-day battery headroom

A full charge lasts up to seven days under typical use, covering a full week of workouts and sleep tracking before the proprietary charging cable is needed. The aluminium-alloy case and 1.8-inch round display handle daily fitness routines, though the bracelet lacks built-in GPS, music storage or third-party app support.

Questions about this item

What wrist size does the Medium silicone strap fit?

The Medium sports strap uses a silicone band designed for average adult wrists; the case is aluminium alloy and the total product weight is 60G.

How do I charge the D18 bracelet, and what mistake should I avoid?

Connect the supplied charging line to the contacts on the back of the host; forcing the connector upside-down bends the pins and stops charging.

When will the 60G battery need replacing, and what signals the end of life?

Expect about 7 days per charge when new; when runtime drops below a day despite a full charge the internal cell is worn out and the unit must be replaced.
