CUKTECH 15 Air Power Bank Delivers Laptop-Grade Charging in Pocket-Friendly Form

For years, mobile professionals faced a frustrating compromise: carry a heavy power brick capable of charging laptops, or settle for phone-only batteries that left MacBooks stranded. The CUKTECH 15 Air power bank eliminates this tradeoff by packing 65W laptop charging and MagSafe compatibility into a package thinner than most smartphones.

At just 0.98 inches thick and 10.8 ounces, the aluminum-bodied power bank defies expectations for high-capacity batteries. Its 15,000mAh capacity delivers tangible results:

• Charges MacBook Air M3 to ≈50% battery
• Fuels iPhone 17 Pro Max to 67% in 30 minutes
• Recharges iPhone 17 Pro Max 1.6 times from empty

What sets the 15 Air apart is its intelligent power distribution. The USB-C PD 3.1 port handles laptops at 65W while simultaneously charging up to two additional devices via USB-C and MagSafe, with total output capped at 100W. This means simultaneous charging of MacBook Air, iPhone, and AirPods without performance drops.

The integrated display provides real-time metrics uncommon in compact batteries: remaining charge percentage, active wattage per port, and estimated recharge time. For developers working remotely, this eliminates guesswork about runtime during coding sessions or client meetings.

Compatibility extends beyond Apple devices, with broad USB-PD support for Windows laptops, Android phones, and peripherals. The GaN (Gallium Nitride) technology enables the slim profile by generating less heat than traditional silicon components.

While MagSafe compatibility works with Apple's magnetic charging ecosystem, the 15 Air doesn't require Apple's Made for MagSafe certification. Third-party testing confirms consistent 15W wireless output when paired with MagSafe-compatible cases.

For mobile-focused developers balancing iOS and macOS workflows, the CUKTECH 15 Air represents a convergence point between portability and capability. It's available through major retailers including Amazon.
