Standards & Compliance
The V3 was evaluated against the following standard:
- JIS C 62133-2:2020 — Safety requirements for portable sealed secondary lithium cells, and for batteries made from them, for use in portable applications — Part 2: Lithium systems. This is the Japanese Industrial Standard aligned with IEC 62133-2 and is a recognised basis for PSE certification under Japan’s Electrical Appliance and Material Safety Act.
The test scope covers the full battery-level and cell-level safety test matrix, including electrical abuse tests (overcharge, forced discharge, external short circuit), mechanical abuse tests (free fall, crush, vibration, mechanical shock), thermal abuse tests (thermal abuse, temperature cycling, high ambient temperature), and environmental tests (low pressure). All 25 test clauses with applicable status returned a Pass verdict.
Verdicts used in the report:
- P (Pass) — test object meets the requirement
- F (Fail) — test object does not meet the requirement
- N/A — test case does not apply to the test object

Frequently Asked Questions
- What does the PSE certification mean for the ETENWOLF V3?
- PSE (Product Safety Electrical Appliance and Material) is a mandatory safety mark required in Japan for lithium-ion battery products. The V3 achieving PSE certification under JIS C 62133-2:2020 means it has passed all required safety tests — including overcharge, short circuit, crush, thermal abuse, and vibration — and is legally permitted for sale in the Japanese market.
- Which test standard was used and why is it relevant?
- JIS C 62133-2:2020 is the Japanese Industrial Standard for the safety of portable sealed secondary lithium cells and batteries. It is technically aligned with the international standard IEC 62133-2 and is the primary standard referenced by Japan’s Electrical Appliance and Material Safety Act for lithium-ion battery packs used in portable devices such as the V3 air inflator.
- What are the key electrical specifications of the V3 battery pack?
- The V3 battery pack operates at a nominal voltage of 11.1V with a rated capacity of 2600mAh and a total energy of 28.86Wh. It charges via a Type-C port at 5V/1.5A or 9V/1.5A and incorporates a discharge cut-off voltage of 8.25V. The safe charging temperature range is 0°C to 45°C.
