What stands out
Detachable lanyard-style USB-C cable and power display. It pairs greater charging headroom and capacity with less recorded weight than the Anker 25K.
Recorded ports: USB-C2 up to 45W output; USB-A up to 18W. These source details help explain its place in the four-product guide.
Single-port output and power sharing
USB-C1 up to 100W output and 65W input. USB-C1 + USB-C2 approximately 65W + 45W when used together. The stated primary-port output should not be assumed when several devices are connected.
Actual charging depends on the laptop, the USB-C charging protocol, cable, and connected devices. A power bank does not force its maximum wattage into a laptop.
Laptop charging fit
USB-C1 up to 100W output is the relevant source specification for one laptop. Confirm that your exact laptop configuration supports USB-C charging and determine the wattage it needs. Heavy workloads can change the result.
Use the Laptop Power Bank Compatibility Checker, then read Can a Power Bank Charge a Laptop? and 65W vs 100W Power Bank for the charging context.
