What PackVolt checks
It turns mAh and voltage into Wh, then maps the battery into the most common passenger guidance bands: up to 100 Wh, 101–160 Wh, and above 160 Wh.
PackVolt converts mAh to Wh, checks the core passenger battery thresholds, and gives you a plain-English read on carry-on vs checked-bag handling in seconds.
It turns mAh and voltage into Wh, then maps the battery into the most common passenger guidance bands: up to 100 Wh, 101–160 Wh, and above 160 Wh.
Use it before you pack, before you buy a new power bank, or when you are standing in the airport wondering whether a battery belongs in your cabin bag.
It cannot override a carrier, airport, or crew decision. Borderline batteries, unusual equipment, and damaged batteries always need extra caution.
Spare lithium-ion batteries and power banks belong in carry-on only; up to 100 Wh is generally the everyday baseline, 101–160 Wh usually needs airline approval, and more than 160 Wh is outside normal passenger baggage allowances.
EASA says spare batteries and power banks must travel in carry-on baggage, be individually protected against short circuit, and should not be recharged or used to power devices on board.
IATA notes that lithium batteries can be carried depending on configuration and watt-hour rating, and that spare batteries are not allowed in checked baggage.
