Common questions
Can I fly with a laptop power bank?
Different countries and airlines may have different restrictions on power banks, but the TSA in the United States technically does not “approve” any power bank, regardless of what it is designed to charge. Instead, they impose a limit on the capacity of the battery itself. The output power of a power bank does not matter, only the capacity of the battery cells inside. At this point, any power bank under 100 watts can be uploaded to the plane. That translates to about 27,000 mAh, so you won’t see much of a power bank bigger than that.
How do I convert watt hours (Wh) to milliamp hours (mAh)?
To determine mAh from Wh, you need to know the Wh and voltage of your device. With these in hand, divide the watt-hours by the volts and multiply by 1,000 to get the milliamp-hours. The formula looks like this: Wh/V x 1,000 = mAh. Alternatively, several calculators freely available on the Internet will give you an accurate answer.
My laptop has a USB-C port. Can I use it to charge my laptop?
Maybe. In addition to data transfer, USB-C can also be used to charge various devices, including laptops. However, just because your laptop has a USB-C port doesn’t necessarily mean you can use it to charge it. In general, laptops with a USB-C port with power delivery (PD) can be charged via USB-C. PD enables higher power delivery via USB-C, which can be used to charge devices that require more power, such as laptops. However, some laptops may require a proprietary charger even if they use a USB-C charging port. The surest way to determine whether or not you can charge your laptop via USB-C is to check the manufacturer’s website or user manual.
