If the power interface and the integrated cable should just provide 60W for consumer devices, it might not be enough for a notebook PC which is shipped with a 65W power supply...

Powerbank Restrictions for Airflight Passengers

    • How Much mAh Power Bank Allowed in Flight?
      1. Airplane Power Bank Capacity Limits:
        • Power banks with a capacity of up to 100Wh (approximately 27,000 mAh) are generally allowed in carry-on luggage without requiring any special approval.
        • If the capacity falls between 100Wh and 160Wh, you typically need airline approval before bringing it on board. Power banks exceeding 160Wh are usually prohibited
      2. Carry-On Only: Power banks must be carried in your hand luggage and are not permitted in checked baggage. This rule is in place due to the potential fire risk associated with lithium-ion batteries, which are easier to manage in the cabin than in the cargo hold.
      3. Quantity Restrictions: Most airlines limit passengers to carrying a maximum of two larger power banks.
    • “Leicht gemacht: mAh in Wattstunden umrechnen”.
      • mAh x V ÷ 1000 = Wh.
      • “Bei einer üblichen Zellspannung des Akkus von 3,7 Volt (V) hätte eine Powerbank mit 27000 mAh also 99,9 Wh und dürfte mit ins Flugzeug”.
