Small tools for better questions. No live airspace data, flight clearance, battery certification, or compatibility promises.
What’s the energy rating?
Enter the nominal pack voltage and the capacity from the same battery label. Do not enter the charger voltage, a single cell’s voltage for a multi-cell pack, or the USB output voltage.
Formula: Wh = nominal V × mAh ÷ 1,000. This is label arithmetic, not usable flight energy or flight-time prediction. Use the manufacturer’s marked Wh rating for travel; ask the airline if markings or values conflict.
Method: FAA PackSafe lithium batteries · checked 19 Sep 2026. Airline and jurisdiction rules still apply.

A planning aid, not a complete or aircraft-specific preflight checklist. Check only what you have actually reviewed. A completed list does not mean a flight is legal or safe.
Session-only: refreshing or leaving the page clears your checks. No location, personal information, or flight records are stored or transmitted.
Read the site-assessment guide ↗A shortlist, not a verdict.
Explore the dated catalog with the flight finder, or compare up to three recorded airframes side by side. Catalog confidence labels are inherited, not fresh verification.
