The AquaFi Hotspot is designed specifically for the rigors of the marine lifestyle. AquaFi delivers fast, reliable WiFi on-the-go with its secure 2.4 GHz connection. AquaFi can connect multiple devices at one time at 4G LTE speeds up to 150 Mbps. All critical components are securely contained within AquaFis waterproof casing, helping it withstand damp environments. Power is no problem either. AquaFi easily snaps in and out from its included charging dock. Want to take AquaFi on shore? Simply use the included AC-DC adapter and plug AquaFi into any 110v power supply.
