What CertiWatt is

CertiWatt is an independent informational utility. We aggregate publicly available aviation regulations, airline policies, manufacturer specifications, and recall notices, and surface a verdict — Allowed, Conditional, Banned, or Insufficient — for a specific power-bank model on a specific flight, with citations to the source documents.

What CertiWatt is not

• CertiWatt is not legal, regulatory, or aviation-safety advice.
• CertiWatt is not an official compliance certificate, product certification, UN38.3 / IEC / 3C substitute, or approval from any regulator, airline, airport, or security authority.
• CertiWatt is not a guarantee that your power bank will be permitted at security or by gate staff. Final authority rests with the airline operator and the security personnel of the originating, transit, and destination jurisdictions.
• CertiWatt does not represent any regulator, airline, manufacturer, or trade body.
• Verdicts are produced asynchronously from public sources. Although we target a 24-hour ingestion lag and re-verify cited URLs daily, real-time correctness is not promised.

Your responsibility

Always verify with your airline before travel, especially for batteries between 100 Wh and 160 Wh which typically require advance approval, and especially in jurisdictions with stricter regional caps (such as Thailand’s 20,000 mAh cap, or China’s 3C-marking requirement). Print or screenshot the manufacturer’s Wh label. Carry power banks in your cabin baggage, never in checked baggage, regardless of what any verdict says.

Partner and API use

• Partners must present CertiWatt verdicts as cited informational outputs, not as guaranteed boarding, screening, or carriage approval.
• Partners should retain and display the citation, ruleset version, verdict ID, and final-authority disclaimer whenever a verdict is shown to an end user or support agent.
• Partners should not use a stale cached verdict as a current answer without checking the active ruleset or a written agreement that permits caching.

Limitation of liability

To the maximum extent permitted by applicable law, CertiWatt and its operators are not liable for any loss arising from reliance on a verdict, including without limitation confiscated devices, missed flights, replacement costs, or follow-on travel disruption. Where liability cannot be excluded, it is capped at the value of the device or two hundred US dollars, whichever is lower.
