The same speed applies to Samsung Galaxy S21, OnePlus 11, and other compatible devices.

  • Approximately 3.75 full charges for iPhone 14 Pro Max

• Durable, Compact Design: Despite its high capacity, the power bank features an advanced slim profile with a fully rubberized cover for a comfortable grip and protection against scratches and drops. At approximately 12.99 ounces, it may be slightly heavier than smaller power banks, but this reflects the robust build, integrated components, and high energy storage.

Benefits & Use Cases

This portable charger excels in real-world scenarios where convenience, speed, and reliability matter most. Imagine arriving at a hotel room without your phone charger—just plug the built-in wall adapter into the outlet, connect your Lightning cable, and start charging immediately. Or take it on long flights where outlets are scarce and space is limited: the compact design fits easily in carry-ons, while the built-in cables mean you’ll always have a compatible connection.

For busy professionals, students, or families using multiple devices with different charging standards, this power bank eliminates the hassle of managing separate chargers. One device powers iPhones, Androids, tablets, and more—no adapters needed. The fast-charging capability ensures critical devices like flagship smartphones stay powered during urgent situations, whether you’re catching up on emails during a layover or navigating a new city.

While slightly heavier than ultra-light models, this weight is justified by the high energy density, rugged construction, and integrated features. The rubberized shell not only improves grip but also protects against daily wear and tear. Whether you’re using it at home, work, or on the road, the Charmast Portable Charger delivers peace of mind with consistent performance and broad compatibility.

Important Notes & Support

It’s important to understand that while the internal capacity is labeled as 20000mAh, actual usable capacity delivered to your devices will be less—typically around 14000–15000mAh—due to energy conversion inefficiencies, which is standard across the industry. The power bank may become warm during fast charging or discharging; this is normal and safe thanks to built-in thermal protection.

If you experience any technical issues, support is available via customer service with responses typically within 24 hours. Compensation is offered for technical problems regardless of return window status. The package includes:

• 1 × 20000mAh power bank
• 1 × user manual
• 1 × mesh pouch for storage
• 24-month warranty support
