Introduction: When Power Banks Meet the Strictest Regulation

In 2026 cross-border e-commerce, TEMU remains the traffic giant that sellers both love and challenge. For power bank sellers, the global portable energy storage boom offers huge opportunities supported by unrivaled China supply chain advantages. However, the platform’s compliance upgrade has raised listing requirements to an all-time high.

Faced with the transition between old and new UL2056 standards, combined IEC requirements, and strict laboratory whitelists, how can sellers break through?As an official TEMU whitelist testing body, Guangdong Energy Storage Testing Technology Co., Ltd. (ESTL) brings you the most complete 2026 compliance guide for power bank listings, helping you pass audits on the first try and seize sales momentum.

Part 1: TEMU New Rules 2026 – Three Iron Rules for Power Banks

The late‑2025 update is not a routine upgrade, but a full safety review for power banks. It sets three non‑negotiable thresholds:

1. Standard Upgrade: Three Compliant Paths

TEMU no longer accepts only old outdated reports. Sellers must choose one valid route:

Path 1 (One‑step solution)Submit a full test report under UL2056:2024 (the most direct and future‑proof option).

Path 2 (Smooth transition)If you hold a full UL2056:2020 report, you must supplement it with a UL2056:2024 difference test report. The 2020 version is not invalidated but requires additional testing to meet the new standard.

Path 3 (International general route)Use the IEC combination system:

• IEC 62368‑1:2023 reportplus one of the following:
  • IEC 62133‑2:2017
  • IEC 62368‑1:2023 AMD1:2021 / A1:2021
  • UL 62133‑2:2020

This path supports multi‑market expansion.

2. Laboratory Strict Limit: Only Whitelist Labs Are Accepted

Reports must be issued by a laboratory on TEMU’s official accreditation list.ESTL is on TEMU’s official whitelist and holds CNAS and CMA accreditations, ensuring high recognition and approval rates.

3. Report Authenticity: CNAS + Timeliness

• All reports must bear a CNAS stamp.
• Report issue date must be within 3 years.
• Applies to all capacities, from 5000mAh to 50000mAh.

Part 2: Common Seller Pain Points – Why Listing Is Repeatedly Rejected

Based on feedback from hundreds of TEMU sellers, the most frequent rejection reasons are:

• Wrong standard version: Using UL2056:2020 without difference testing.
• Product‑report mismatch: Inconsistent battery voltage, capacity, model, layout, or wiring.
• Unauthorized lab: Report has CNAS but the lab is not on TEMU’s whitelist.

ESTL specializes in solving these technical barriers.
