Test Equipment & Setup

Item	Details
Test Equipment	Constant Temperature & Humidity Chamber / Oven / Power Meter
Room Temperature	23 °C
Room Humidity	60% RH
Low-Temperature Charge Condition	0 °C, storage duration: 2 hours
Mid-Temperature Charge Condition	45 °C, storage duration: 2 hours
High-Temperature Discharge Condition	74 °C, storage duration: 2 hours
Low-Temperature Discharge Condition	-20 °C, storage duration: 2 hours

Test Procedure

Pre-Test: Record ambient conditions (temperature 23 °C, humidity 60%). Assign sample IDs 4#, 5#, 6#. Confirm all samples are in normal initial working condition.
Low-Temperature Charge Test: Place samples in the constant temperature chamber set to 0 °C. Allow samples to stabilize for 2 hours. Apply charging conditions and observe charging display behavior.
Mid-Temperature Charge Test: Set chamber to 45 °C. Allow samples to stabilize for 2 hours. Apply charging conditions and observe charging display behavior.
High-Temperature Discharge Test: Set chamber/oven to 74 °C. Allow samples to stabilize for 2 hours. Power on samples and evaluate operational performance and stability.
Low-Temperature Discharge Test: Set chamber to -20 °C. Allow samples to stabilize for 2 hours. Power on samples and evaluate operational performance and stability.
Post-Test: Return samples to room temperature. Document all observations, record any anomalies, and compare against acceptance criteria.

Acceptance Criteria: Samples must operate normally within the specified environmental temperature range. Charging display must function correctly under charge conditions. Samples must power on and perform normally under discharge conditions.

Test Data & Results

Sample ID	Test Condition	Observations / Issue Description
4#–6#	Low-Temperature Charge Test	After 2 hours storage at 0 °C, charging display functioned normally.
4#–6#	Mid-Temperature Charge Test	After 2 hours storage at 45 °C, charging display functioned normally.
4#–6#	High-Temperature Discharge Test	After 2 hours storage at 74 °C, samples powered on normally and performance was normal.
4#–6#	Low-Temperature Discharge Test	After 2 hours storage at -20 °C, samples powered on normally and performance was normal.

Test Pictures: Low/High Temperature Charge Test images and High/Low Temperature Discharge Test images were captured during testing (see original report appendix).

Overall Result: All 3 samples passed the operating temperature test process. No functional failures were observed. Power-on stability was good and overall performance was satisfactory across all four temperature conditions.

Frequently Asked Questions

What temperature range does the HB1 Air Pump support for charging?

The HB1 was tested for charging performance at 0 °C (low temperature) and 45 °C (mid temperature). In both conditions, the charging display functioned normally after 2 hours of thermal stabilization, indicating the product operates reliably within the 0–45 °C charging range.

Can the HB1 Air Pump be used in extreme heat or cold for discharge (operation)?

Yes. The HB1 was tested at 74 °C (high temperature) and -20 °C (low temperature) under discharge conditions. After 2 hours of storage at each temperature, all 3 samples powered on normally and performed as expected, confirming reliable operation across this extreme discharge range.

What test standard was used for this operating temperature test?

This test was conducted against ETENWOLF’s Internal Control Standard. The acceptance criterion requires that samples operate normally within the specified environmental temperature ranges. No external standard such as IEC or UL was referenced for this specific test.

How many samples were tested and what was the overall outcome?

Three samples (IDs 4#, 5#, and 6#) were tested across all four temperature conditions. All three passed without any functional failures. The power-on stability and overall performance were rated as good, resulting in a final verdict of Pass (■ 合格).
