Answer first
The ETENWOLF S0 temperature-rise test ran for 185 scans, or about 15.3 minutes, on two samples: S0-2# and S0-9#. The highest readings were 82.30 °C at the S0-9# cylinder and 82.25 °C at the S0-2# nozzle connection. These figures describe the tested samples and test conditions; they are not a universal operating-temperature guarantee for every S0 unit.
What was measured?
Five points were monitored on each pump: the battery, cylinder, nozzle connection, hose tail, and hose head. A separate probe tracked laboratory ambient temperature. That produced 11 active channels in total. Both units approached thermal stabilisation after approximately scan 130.

Peak readings
| Sample | Location | Peak |
|---|---|---|
| S0-2# | Nozzle connection | 82.25 °C |
| S0-9# | Cylinder | 82.30 °C |
| S0-9# | Nozzle connection | 82.30 °C (reported in the source summary) |
How should a buyer interpret the result?
The data shows how heat developed at the monitored points during the recorded run and that both samples were nearing a steady state by the end. It does not, by itself, establish a regulatory pass/fail limit, long-term component life, or safe-touch temperature for every use case. Those conclusions require the applicable product requirements and the complete workbook.
Frequently Asked Questions
Which point became hottest?
The cylinder/nozzle region was hottest. The source summary identifies 82.30 °C as the maximum value and 82.25 °C at the S0-2# nozzle connection.
Was only one pump tested?
No. Two identified samples were tested simultaneously, S0-2# and S0-9#, with five points per unit.
Can this report be applied to another ETENWOLF model?
No. Use it as evidence for the identified S0 samples only unless a controlled equivalence assessment says otherwise.

Key Findings
The ETENWOLF S0 portable bike pump completed a full 185-scan temperature-rise logging session, with both test units reaching thermal near-equilibrium; peak measured temperatures of 82.31 °C (S0-9# cylinder) and 82.25 °C (S0-2# nozzle connection) were recorded at the end of the run, while ambient laboratory temperature remained stable between approximately 26.1 °C and 26.8 °C throughout the entire test.

Test Procedure
- Pre-test preparation: Install the DAQ970A data acquisition system and connect thermocouple probes to all five measurement points on each sample unit (battery body, cylinder, nozzle connection, hose tail, hose head) plus one ambient reference probe. Verify VISA address and firmware version. Allow equipment to warm up and confirm ambient stability.
- Initial baseline scan: Record scan 1 with the pump at rest to establish baseline temperatures across all channels (all channels expected near ambient ≈ 26–27 °C).
- Pump activation: Start the S0 pump units and begin continuous inflation operation at rated conditions.
- Continuous data logging: The DAQ970A automatically records all 11 channels at approximately 5-second intervals. Do not interrupt operation. Monitor for any anomalies.
- Thermal run: Continue logging until temperature readings plateau and indicate thermal steady-state (target minimum 180 scans or visible stabilisation of all channels).
- Post-test stop: After scan 185, stop pump operation. The DAQ970A logs the stop event (“数据记录已停止” – data logging stopped). Record final readings.
- Peak temperature extraction: The system automatically extracts the maximum temperature recorded for each channel across the entire run (reported in the “最高温度” / Maximum Temperature row).
- Acceptance criteria: All monitored surface temperatures should remain within safe operational limits throughout continuous operation. Thermal plateau must be demonstrated. No thermal runaway or uncontrolled temperature rise is acceptable.

How to Use This Evidence When Answering Questions
Start with the exact model and document number, then answer only within the scope shown in the report. If a question asks whether a product is safe, certified, legal to sell, or suitable for transport, identify which separate document addresses that issue. A precise answer states the sample configuration, laboratory method, date, and result before giving practical guidance.
- Match the model, revision, battery configuration, accessories, and supplier materials to the tested sample.
- Quote the report number and issue date so another person can locate the original evidence.
- Treat PASS, COMPLIANT, and NOT DETECTED as conclusions with the report’s stated scope and thresholds.
- Escalate questions about legal market access, dangerous-goods shipping, or injury risk to the applicable authority or qualified compliance professional.
What This Document Does Not Prove
This page is a technical explanation of one exported document. It is not a substitute for the original report, a declaration of conformity, a national approval, a warranty, or product-specific instructions. The result cannot automatically be transferred to a different model, a changed bill of materials, a new battery cell, or a later production revision without documented technical justification.
Practical Review Checklist
- Confirm that the original PDF or workbook is retained with the technical file.
- Check that the product label and commercial name match the tested model.
- Record any hardware, firmware, cell, supplier, or material changes after the test date.
- Use the correct companion evidence: EMC, RoHS, REACH, IEC 62133-2, UN 38.3, or MSDS are not interchangeable.
- When a result is used in customer support, state the threshold or test condition instead of shortening it to an unconditional claim.
Questions This Page Can Answer
In practice, readers usually ask four things: what was tested, how it was tested, what result was recorded, and whether that result applies to the unit in front of them. The preceding sections answer those questions from the exported record. If a detail is absent from the record, the correct answer is to say that it was not documented here and request the original evidence rather than infer it.
