Absolutely—just make sure the power bank has USB-C port and offers at least 65W or 100W output. Many high-end usb c portable charger models now support charging laptops like MacBook, Dell XPS, or other USB-C-compatible notebooks.
A 20000mAh power bank can charge an iPhone 15 about 4–5 times or a Samsung Galaxy around 3–4 times, depending on the phone battery size. You can roughly estimate by dividing the power bank’s capacity by your phone’s battery (e.g., 20000mAh ÷ 4000mAh = 5 times), then factoring in 10–20% energy loss due to heat and voltage conversion.
Yes—airlines generally allow power banks under 100Wh (watt-hours) in carry-on luggage. To calculate if your power bank meets this limit, use the formula:Wh = (mAh × V) ÷ 1000. For example, a 20000mAh power bank with a standard 3.7V lithium battery equals 74Wh, which is well within the allowed range. Note: all power banks must be placed in hand luggage, and some airlines may require approval for devices above 100Wh. Always confirm with your carrier before travel.
