Certification in charging products is evolving from a basic compliance step into a strategic tool. It now helps demonstrate reliability, compatibility, and product credibility, becoming an important factor in how products compete in the market.

On March 24, 2026, USB-IF updated the USB PD3 CTS Q2 2026 package in its document library as part of its USB Power Delivery compliance materials. The update matters because CTS materials support validation workflow, lab preparation, and certification readiness for USB-C products, while related Q2 2026 USB PD compliance documents show that USB-IF continued refreshing its compliance infrastructure during March 2026.

On March 9, 2026, USB-IF published the Q2 2026 USB Power Delivery Compliance Test Specification, updating the official test basis for USB PD products. The update matters for chargers, cables, controllers, and USB-C devices because it strengthens the framework for protocol validation, interoperability, and certification readiness across the fast-charging ecosystem.

IATA continues to reaffirm that power banks are treated as spare lithium batteries, not ordinary travel electronics. As a result, they must be carried in cabin baggage, remain subject to watt-hour and quantity limits, and may face additional airline-specific restrictions, making battery classification and safe handling important parts of air travel preparation.

IATA’s revised passenger guidance confirms that power banks are treated as spare lithium batteries, not ordinary electronics. They must be carried in cabin baggage, remain subject to watt-hour limits and possible airline approval rules, and require more careful handling because aviation safety policies distinguish spare batteries from batteries installed in equipment.

IATA’s 2026 dangerous goods update cycle places stronger emphasis on how passengers carry and use power banks in the cabin. Power banks remain classified as spare lithium batteries and must stay in cabin baggage, while updated guidance also highlights in-flight charging behavior, device accessibility, and airline-level safety controls related to lithium battery risks.

In March 2026, USB-IF released an updated USB Power Delivery Compliance Test Specification for chargers, cables, controllers, and end devices. The update strengthens the testing basis for protocol validation, interoperability, and certification readiness across the USB-C fast-charging ecosystem.

On 1 January 2026, IATA issued Addendum 1 to the 67th Edition of the Dangerous Goods Regulations, reinforcing updated battery air cargo compliance requirements. The addendum matters because lithium battery shipments must follow the latest rule language on packing instructions, documentation, UN 38.3 testing, and the expanded 30% state-of-charge restrictions affecting certain batteries packed with equipment.

The EU is moving toward more standardized carbon footprint reporting for batteries placed on the European market. The methodology supported by the European Commission’s Joint Research Centre helps create a more consistent way to measure battery-related emissions, which may affect lifecycle analysis, supplier traceability, and future compliance preparation under the EU battery regulatory framework.
