44 mm Square Touch Display

The allentian S9 Promax is a Bluetooth-enabled smartwatch with a 44 mm square TFT screen and aluminium-alloy case. It supports voice calls from the wrist and tracks heart rate, blood oxygen, blood pressure, steps and sleep. Wireless charging keeps the 155 g unit running for up to seven days. Silicone straps with a classic buckle complete the neutral black finish.

Android and iOS Users Seeking Core Health Tools

This watch suits adults and teenagers who want call handling, daily activity data and sleep insights without a bulky device. The single silicone band size and life-waterproof rating limit appeal for swimmers, serious athletes or anyone needing interchangeable straps, advanced training metrics or deeper water resistance. Buyers who want onboard GPS, music storage or third-party apps should consider other platforms.

Up to Seven Days Battery Between Wireless Charges

Endurance is rated at seven days or less depending on call volume and sensor use, so the charging interval is the key figure for deciding if the S9 Promax fits your routine. Wireless charging removes cable hassle, but heavy Bluetooth calling will shorten the window noticeably. Plan charge cycles around your busiest days.

Questions about this item

Will the silicone strap or the 155g aluminum-alloy case need replacement first?

The silicone strap will wear and stretch before the aluminum-alloy case, so expect to swap the strap first.

Does the 7-day endurance or the TFT screen brightness hit its limit first on long hikes?

The 7-day battery runs out before the TFT screen reaches any brightness limit during continuous outdoor use.

How much heat or noise does the wireless charger produce during an all-day top-up?

Wireless charging stays cool and silent; the watch itself generates no audible noise and only slight warmth.
