Never run out of power again with the Anker 621 Power Bank with Built-in Lightning Connector in Black, the ultra-portable charging solution engineered for iPhone users, travelers, and busy professionals who demand reliable, on-the-go power without the hassle of extra cables. At its core lies Anker’s innovative built-in Lightning connector design, eliminating the need for separate charging cables by allowing you to directly plug your iPhone into the power bank for instant charging—perfect for quick top-ups during commutes, travel, or emergency situations where every minute counts.
The MFi certification (Made for iPhone/iPad) guarantees 100% compatibility and safe charging for your Apple devices, ensuring no warning messages or compatibility issues that plague non-certified third-party chargers. This official Apple certification provides peace of mind that your iPhone 15/15 Pro/15 Plus/15 Pro Max, iPhone 14 series, iPhone 13 series, and earlier Lightning-equipped models will charge safely and efficiently without risking damage to your device’s battery or charging port.
Powering this compact powerhouse is a high-quality 5,000mAh lithium-polymer battery that delivers approximately 1.5 full charges for iPhone 15/14/13 models—sufficient for extending your day during travel, long commutes, or outdoor adventures without adding significant bulk to your bag. The 12W output provides optimized charging speeds for Lightning devices, balancing fast charging with battery health preservation to extend your iPhone’s overall battery lifespan.
Measuring compact dimensions and weighing only 135 g, the Anker 621 achieves the perfect balance between capacity and portability. The slim, pocket-friendly profile slips easily into jeans pockets, small purses, or jacket pockets without adding noticeable bulk, while the premium matte black finish features a fingerprint-resistant coating that maintains its sleek appearance through daily use. The integrated Lightning connector folds neatly into the body when not in use, protecting the connector from damage and keeping your bag free from cable clutter.
For versatile charging options, the additional USB-C input port enables recharging the power bank itself via USB-C cable (included), while also supporting pass-through charging to charge your iPhone while simultaneously recharging the power bank. The intelligent PowerIQ technology automatically detects your connected device and delivers the optimal charging current for safe, efficient power delivery. The multi-protect safety system provides surge protection, short-circuit prevention, and temperature control to safeguard both your power bank and connected devices during charging.
The LED power indicator displays remaining battery capacity with four precision LEDs (25%/50%/75%/100%), eliminating guesswork about when to recharge your power bank. The trickle-charging mode (activated by double-pressing the power button) provides optimized low-current charging for delicate devices like wireless earbuds, smartwatches, or fitness trackers—preventing overcharging and extending the lifespan of smaller batteries.
Certified for travel-friendly use, the Anker 621 meets airline carry-on requirements and includes comprehensive safety certifications for global use. The durable construction with reinforced corners and impact-resistant materials withstands daily drops, bumps, and travel rigors, while the premium internal components ensure consistent performance through hundreds of charge cycles. The eco-friendly packaging uses recyclable materials aligned with Anker’s sustainability commitments.
For iPhone users, the seamless integration with iOS devices means no setup required—simply plug and charge. The compact form factor makes it ideal for minimalist carry setups, while the built-in connector design eliminates the frustration of forgotten or lost Lightning cables. Whether you’re commuting to work, traveling internationally, attending outdoor events, or simply extending your iPhone’s battery life during busy days, the Anker 621 Power Bank delivers dependable, cable-free charging with Anker’s legendary reliability.
