Go further, longer. Premium battery cells provide enough power to fully charge almost any smartphone 4-6 times, day after day and everywhere. Superior materials in a high-quality construction make it incredibly durable while still being comfortable to hold thanks to its ergonomic shape.

Two outputs, double the possibilities. With an impressive size-to-capacity ratio, the GS15 is equipped with 2 USB Type-A ports for charging two devices simultaneously. Both ports feature our proprietary technology for smart and fast charging, making it the perfect choice for on-the-go, whether alone or with a friend.

Don't get caught without power. The GS15 is designed to work with virtually any device that can be charged via USB. With a simple press of a button, up to 4 LED lights indicate the remaining battery level, so you no longer have to worry when you're not near an outlet.

The versatility of two inputs. The GS15 is equipped not only with a standard Micro-USB input but also with a Type-C input. This versatility is another reason why it is perfectly portable. The Type-C input is also an ideal future-proof addition to sync with the growing trend of Type-C ports on devices.
