Can a power bank charge my laptop?

Yes, if it supports USB-C PD at 45W or higher. Most modern laptops charge via USB-C. Check your laptop's required wattage—gaming laptops may need 100W+.

How long do power banks last?

Most quality power banks maintain 80%+ capacity after 500 charge cycles (roughly 2-3 years of regular use). Avoid extreme temperatures for longest life.
