Charging & Power
Charging is unglamorous and disproportionately important: it is the category where a bad cable silently limits an expensive device. The specification to read is the wattage each port can deliver simultaneously, not the total on the label.
What actually matters
The specifications that change the answer
- Per-port wattage when several devices are plugged in at once
- USB Power Delivery version, which decides laptop charging support
- Cable ratings for both wattage and data speed, which are separate
- Airline-safe capacity in watt-hours, not just milliamp-hours
What to skip
- Banks above 100Wh, which cannot fly in hand luggage
- Chargers with unlisted brand cells, where safety data is absent
- Cables bought on price alone when they carry 100W
