An original synthesis of the linked evidence. SmartWearGuide has not hands-on tested this device.
AICE Lite Plus combines cooling plates, a dual-turbine fan system and heating in one neck-worn device. Its advantage is the ability to choose between moving air and direct thermal contact, rather than expecting a fan to make ambient air colder. App control and an automatic mode add convenience if the collar fits comfortably.
The manufacturer lists a 6,000 mAh battery, 506 g weight and a three-to-twenty-hour runtime range. The width of that range is the important detail: operating mode changes endurance substantially. The documented temperature setpoints describe device settings, not a guaranteed body or room temperature.
We would shortlist it for someone who wants both warming and cooling from one wearable and accepts a heavier collar. Inspect fit, charging, cleaning and the controls available without the phone. No independent comparison of cooling power, noise or battery performance was established in this pass, so the review does not rank its engineering above every rival. Its place reflects the breadth of documented modes, while a basic fan remains the more straightforward option when airflow is all that is needed.
Why #4 in this selectionFourth as a versatile thermal collar with a clearly disclosed runtime range. Its usefulness depends on whether contact cooling adds enough benefit to justify the weight.
The compromiseThe longest runtime belongs to favourable operating conditions. Neck pressure, fan noise and app dependence may matter more than the number of modes.
