The 10 Best Portable Chargers for 2025
2025-09-14 · 5 min read
A dead phone in a new city is a genuine emergency. Portable chargers have shrunk dramatically while capacity has grown, meaning there's no excuse to leave home without backup power. The best ones charge fast, fit in a pocket, and survive the chaos of daily carry.
The Anker 737 Power Bank at $110 packs 24,000mAh into a surprisingly compact form. Two USB-C ports and one USB-A deliver up to 140W combined output—enough to charge a MacBook Air at full speed. It's the one charger that genuinely replaces a wall adapter for short trips.
For pocket carry, the Anker Nano Power Bank 5,000mAh at $30 has a built-in USB-C connector that plugs directly into your phone. No cable needed. At credit-card size, it disappears into any pocket and provides roughly one full iPhone charge. The foldable connector sits flush when not in use.
Mophie's Snap+ Juice Pack Mini at $50 magnetically attaches to any MagSafe iPhone. 5,000mAh provides a full charge while maintaining wireless MagSafe functionality. The built-in stand props your phone up while charging—perfect for desk use or nightstand placement.
Baseus 20,000mAh 65W Power Bank at $55 is the value champion. PD 3.0 fast charging fills an iPhone to 50% in under 30 minutes, and the 65W output handles laptop charging in emergencies. The LED display shows remaining capacity without guessing. Remarkable specs for the price.
For outdoor adventures, the BioLite Charge 40 PD at $50 wraps 10,000mAh in a rubberized, water-resistant shell. The integrated carabiner clips to backpack straps, and the body survives drops that would crack plastic competitors. It's the charger for people who aren't gentle with their gear.
Capacity math: divide the mAh rating by roughly 1.5 to get real-world phone charges (accounting for conversion loss). A 10,000mAh bank provides about 2.5 iPhone charges, not the 3+ that marketing claims. Buy slightly more capacity than you think you need.
