Frequently Asked Questions
How many Wh or mAh do I need to charge my laptop?
Aim for a power bank with enough watt-hours to cover the laptop battery size. A typical 13–14" laptop has a 40–60Wh battery, so a 72Wh bank can often provide one full charge; larger 15–16" laptops may need 90–100Wh for a full charge. Use the manufacturer's Wh rating when available rather than converting mAh when possible.
Will a 100W power bank actually charge my laptop at full speed?
If your laptop accepts 100W or less via USB-C PD, a 100W PD power bank will usually charge it at full speed. High-performance laptops that expect 140W or more will charge slower from a 100W bank. Check your laptop's input spec (on the power adapter or manufacturer site) and match or exceed it for full-speed charging.
Can I bring these power banks on a plane?
Most airlines allow power banks up to 100Wh in carry-on without approval — they must not go in checked baggage. Power banks above 100Wh often require airline approval and are sometimes restricted. Check the Wh rating on the device and your carrier's policy before traveling; models explicitly listing under-100Wh (or 99Wh) are safest for travel.
Do I need a special cable to get full 100W charging?
Yes — to achieve 100W PD you need a USB-C cable rated for 5A/100W (often called 100W or 5A cables). Some power banks include the right cable; for others buy a certified 100W cable to ensure full performance.
What's the trade-off between mAh and Wh?
mAh measures charge at the cell's nominal voltage, while Wh measures energy (mAh × voltage ÷ 1000). Because USB power banks use different internal voltages, Wh is the more reliable measure for comparing total energy and for airline rules. Use the Wh rating when available.
