Buying Guide

Check airline carry-on battery limits

Airlines and regulators limit battery capacity for carry-on lithium-ion packs; prioritize units at or below typical 100 Wh limits and verify mAh-to-Wh equivalence before travel

Prioritize USB-C PD output for fast charging

USB-C Power Delivery (e.g., 22.5W–35W) charges modern phones fastest and supports USB-C to laptop or tablet top-ups when needed

Consider wireless MagSafe convenience

Magnetic MagSafe-compatible chargers simplify cable-free top-ups for supported iPhone models but typically offer lower wattage than wired PD outputs

Balance capacity vs. weight for travel

20,000 mAh banks provide multiple phone charges but add bulk; 10,000 mAh options reduce weight for short trips or minimalist packing

Look for QC4.0 and PD compatibility

Compatibility with Quick Charge 4.0 and PD3.0 ensures broader fast-charging support across Android and Apple devices when using appropriate cables
