What's in the Box

🔋 30W Two-Way Fast Charging Technology

This means you can charge an iPhone 15 Pro from 0% to 50% in approximately 30 minutes. Equally impressive, the power bank itself can be fully recharged in just 2-2.5 hours using a 18W or higher USB-C charger – much faster than traditional 5W charging.
