What this watch does

The allentian As19 Ultra Max is a wrist-worn device that pairs with Android and iOS phones to deliver step counting, heart-rate, blood-pressure and sleep monitoring. It also handles Bluetooth calls, message reminders and remote camera control, making it suited for anyone who wants health data and basic communication without reaching for their phone.

Battery life and charging

Wireless charging keeps the unit topped up, and the supplier rates endurance at seven to fourteen days depending on usage. The plastic case and TFT screen are rated for life-waterproof protection, so sweat, rain and hand-washing are not a concern during normal wear.

Deciding factor

If you need a watch that can answer calls directly from the wrist and track core health metrics for up to two weeks per charge, this model fits; buyers who require built-in GPS, onboard music storage or third-party app support should look elsewhere.

Questions about this item

How do I set up the As19 Ultra Max with my phone and what step do people miss?

Which parts will need replacement during the life of the As19 Ultra Max?

The silicone sport strap and the wireless charging cable are the only accessories included; both wear out and can be swapped for standard equivalents.

What limits daily use of the As19 Ultra Max before I must recharge?

Battery endurance is rated at seven to fourteen days; heavy Bluetooth calling, continuous heart-rate tracking and frequent notifications push you toward the seven-day mark.
