With enough power to recharge just about any smartphone 4-6 full times, you can remain connected for days, without being tethered. Plus, the carbon fiber texture provides a more secure grip, while the rounded shape is ergonomic, which makes it even more suitable for bringing along with you.
Never Run On Empty Again
The GS28 has a built-in battery indicator with a digitized LED display. It doesn't get any more straightforward than a clear percentage of the remaining battery level. With this detailed indication, you'll always know when it's time to recharge the power bank, so you'll never have to worry about running on empty again.
Two Outputs, Two Times The Possibilities
Multi-tasking? The GS28 is equipped with 2 USB Type-A ports, so it can charge up to 2 devices simultaneously. It's the perfect companion for those of us balancing multiple devices while on-the-go, or when traveling with a friend.
Two Inputs, Greater The Convenience
The GS28 is equipped with a Micro-USB input, but that's most power banks. What sets it apart is its Type-C input. Dual input options means greater convenience. Plus, it's the perfect future-proof addition to sync with the growing trend of Type-C ports on devices.
