Standards & Compliance
The X5 Pro was evaluated against the following standard:
- ANSI/CAN/UL 2743:2023 — Standard for Safety of Portable Jump Starters. This is a harmonised American National Standard and Canadian standard covering portable battery-based jump starters including those incorporating an integrated air compressor. It addresses electrical safety, mechanical robustness, thermal performance, and abnormal condition resilience.
Key safety areas verified under UL 2743:2023 include:
- Electrical safety — power input limits, charging system integrity, output short-circuit protection, and reverse polarity protection.
- Thermal safety — normal temperature operation and overcharge protection for the 4S1P lithium cell pack.
- Mechanical durability — vibration, impact, drop, hydrostatic strength, cold bend, and mold stress tests confirming the enclosure and cable assembly withstand real-world stresses.
- Clamp and ampacity — booster cable clamps and internal conductors are validated to safely carry the rated 180 A start current.
No subcontracting of test items to external laboratories was declared. All tests were performed in-house at the Waltek Dongguan facility.
