Portable chargers, or power banks, are essential for anyone who relies on smartphones, tablets, or other gadgets away from outlets. In 2026, with devices demanding faster USB-C PD charging and higher capacities, we've rigorously tested models for actual output (not just claimed mAh), recharge times, heat management, and multi-device support. Our picks balance portability, power, and price to keep you charged during travel, hikes, or long workdays.
Quick Pick
INIU Portable Charger, Smallest 22.5W 20000mAh USB C in & Out Power Bank
Compact yet powerful with 20,000mAh capacity, 22.5W PD/QC 4.0 fast charging, LED display, and bi-directional USB-C. Perfect for iPhone 17/16, Samsung S24, and more. Check current price.
Modern phones like the iPhone 17 series or Samsung Galaxy S24 drain batteries faster with AI features and high-res screens. A good power bank delivers 60-80% of its rated capacity in real use (due to efficiency losses) and supports 18W+ PD for quick top-ups. We prioritize models with at least 10,000mAh, multiple ports, and safety features like overheat protection.
