Test Procedure
- Pre-Test: Record baseline appearance and functional status of all 3 sample units. Confirm laboratory environment: 24 °C, 45 % RH.
- High-Temperature Exposure: Place samples in the constant temperature and humidity chamber. Set to 60 °C / 80 % RH. Hold for 2 hours.
- Low-Temperature Exposure: Adjust chamber to −20 °C. Hold for 2 hours.
- Extended Storage: Continue storage cycle to accumulate a total of 72 hours under the programmed temperature profile.
- Post-Test Functional Test: Remove samples from chamber. Power on each unit and verify normal operation. Verify charging function.
- Acceptance Criteria: No appearance abnormalities; all functional features operate normally after exposure.

Frequently Asked Questions
What temperature range was the ETENWOLF S0 pump tested to withstand in storage?
The ETENWOLF S0 was tested at a high-temperature extreme of 60 °C with 80 % relative humidity for 2 hours, and a low-temperature extreme of −20 °C for 2 hours, with a total programmed storage duration of 72 hours.
Did the ETENWOLF S0 pump pass the temperature storage cycle test?
Yes. All 3 samples passed. After completing the 72-hour high/low temperature storage cycle, every unit powered on normally and charged normally with no appearance anomalies or functional failures recorded.
What equipment was used for the ETENWOLF S0 temperature storage test?
A constant temperature and humidity testing machine (恒温恒湿试验机) was used to execute the programmed thermal profile across both high-temperature and low-temperature exposure phases.
Why is temperature storage testing important for a portable bike pump?
Portable bike pumps are frequently stored in environments such as car trunks, garages, or outdoor bags that can reach extreme temperatures. Temperature storage testing confirms that the product’s housing, battery, electronics, and seals remain intact and functional after prolonged exposure to heat and cold, ensuring reliability when the user actually needs the pump.
