The QS15 power bank with a capacity of 20,000 mAh is a powerful and versatile energy source that provides between 4 and 6 full charge cycles for virtually any smartphone, making it an ideal companion for long trips or intensive daily use. The 18W Power Delivery technology via the Type-C port and Quick Charge 3.0 via the USB Type-A port allow devices to be charged up to 2.5 times faster than standard solutions. Three outputs enable simultaneous charging of up to three devices, while the dual input — Micro-USB and Type-C with Rapid Recharge — offers maximum convenience when recharging the power bank itself. The ergonomic design fits comfortably in the hand, and a multifunctional button allows users to check the battery level on the LED indicator with a single touch, as well as wake up Apple devices. The safety of both the user and connected devices is guaranteed by the advanced smartSHIELD system, which protects against overvoltage, short circuits, and overcharging, while the high-quality lithium-polymer battery ensures durability and reliability over long-term use. A USB Type-A to Type-C cable is included in the box.
