Portable Power

What to check before buying a high-capacity power bank.

Big capacity numbers are only part of the story. Shoppers should compare usable output, USB-C wattage, cable quality, airline limits, display behavior, and device compatibility.

Good Fit

• Long travel days with phones, tablets, cameras, and small accessories.
• Work bags where integrated cables reduce clutter.
• Users who understand that delivered capacity is lower than cell rating.

Tradeoffs

Higher-capacity batteries are heavier. Laptop charging requires more than capacity: output wattage, port behavior, and cable support matter.
