Safety
Temperature Control System
When assessing glove safety, the overheat protection function is a crucial indicator. We tested the heating system of the gloves and confirmed that it includes overheat protection. When the gloves are set to high temperature, the temperature automatically reduces to medium level after about 15 minutes. This design effectively prevents the risk of overheating, ensures user safety during use, and increases the sense of security when wearing them.
Battery Safety
Both gloves are equipped with 2200 mAh lithium batteries, providing significant heating effects and long battery life. We checked the battery connections of the gloves to ensure their design is appropriate and free from risks such as electrical leaks or short circuits. During testing, no risks of leaks or short circuits were found. Furthermore, the gloves have passed international safety certifications (such as CE and FCC), ensuring compliance with applicable safety standards and allowing users to use them with confidence.
To comprehensively evaluate the suitability of the heated gloves, we conducted tests in two different temperature environments: 12°C (53.6°F) and 5°C (41°F).
12°C Environment:
In the mild climate of 12°C (53.6°F), the heating function of the gloves works well; they heat up quickly and maintain a comfortable temperature. They are suitable for use alone and meet daily travel needs by providing sufficient warmth.
5°C Environment:
At the low temperature of 5°C (41°F), the gloves can still provide a certain degree of warmth, but for use alone, they are somewhat insufficient. At this temperature, the heating function can serve as a supplementary feature, so it is recommended to use them as liner gloves in combination with other gloves.
Summary:
The heated gloves perform well at temperatures of 12°C (53.6°F) and above, providing sufficient warmth for standalone use. However, their heating capability is insufficient at 5°C (41°F) and below, so they are only recommended as liner gloves that should be combined with thicker, warmer gloves.
Battery Life
Battery Duration
When testing the battery life of the gloves, we selected different temperature settings and recorded the continuous operating time of the battery in a specific environment. The test conditions were set to 15°C (59°F) and monitored in real-time with an electronic thermometer. In High-Temperature mode, the battery lasts about 2 hours; in Medium-Temperature mode, the duration is approximately 3.5 hours, while in Low-Temperature mode, it extends to 6.5 hours. This data helps us better understand the performance of the gloves under different conditions, allowing users to choose the appropriate temperature setting as needed.
Charging Time
Charging efficiency was also an important focus of our tests. Actual measurements show that it takes about 3 hours to charge the battery from fully discharged to fully charged. During the charging process, the indicator light blinks and turns green once the battery is fully charged, allowing users to easily monitor the charging status. Although the 3-hour charging time is not particularly fast, it is sufficient for daily use, especially since the Low-Temperature setting offers a longer battery life, reducing the need for frequent recharging.
