Best Portable Chargers & Power Banks in 2025
From slim daily carries to airline-compliant laptop chargers, these are the power banks that survived our stress tests and kept sensitive devices safe.
Key takeaways
- 27,000 mAh is the new sweet spot for airline approval. Anything larger needs pre-approval before boarding.
- Look for USB-C PD 3.1 with 140W or 240W support if you charge modern laptops. Dual USB-C ports let you power-share with colleagues.
- Smart displays and apps can be helpful, but prioritize safety: UL certification and over-temperature protection matter more.

Safety checklist
Inspect power banks quarterly for swelling, discoloration, or warm spots. If you see issues, recycle through manufacturer programs. Store packs at 40–60% charge when not in use to reduce cell degradation. Avoid stacking power banks in backpacks—dedicated sleeves keep the vents exposed.
Build your charging kit
Pair your power bank with braided 240W USB-C cables, a short USB-C to Lightning cable for legacy devices, and a multi-port GaN wall adapter. Keeping everything in a small pouch means you can recharge from hotel lamps, airplanes, or co-working desks without scrambling for outlets.
For longer trips, add a folding laptop stand and our webcam picks so your hybrid work setup stays consistent everywhere.
