The Extō USB Type C® - Charge Up To 59% Faster Than Standard USB

Better, Faster, Stronger, Smarter. Introducing The Surge-Protected Extō Smart USB Type C® - a better, faster, and easier to use solution for charging some of your notebooks, mobile devices, and other electronic accessories. USB C cords have smaller connectors that can be inserted in any orientation, and they push more power for faster charging. Combined with our Smart Chip technology, the new Extō Smart USB Type C® charges up to 59% faster than standard USB ports saving hours of waiting time. 

Our Extō Smart USB Type C® has a single Smart USB C port to be used with any USB Type C® device and also has our standard Smart USB port for legacy device charging. The USB ports have a combined 5.4AMPS of charging power, with max 2.4 from the USB and 3AMPS from USB Type C port.

The smart chip communicates with the device to identify optimal charging power and throttles the power from the Extō to the device in a way that protects the device battery while optimizing charging speed. This smart chip technology reduces battery fatigue, helping extend device life by preserving the internal battery structure (typically lithium ion) so you can keep your phone, tablet, or laptop going strong for many months or years to come, even after hundreds of charging cycles.

As with our standard Smart USB product line, once your device is charged, our Smart USB and USB C ports also automatically shut off helping protect the device battery from voltage wear and excess heat. With a healthy battery, your device can live longer and perform better. The Extō Smart Chip USB Type C® patented All-Device™ layout even lets you charge all your devices at once. It can hold two standard plugs (or a plug and a bulb socket) and both USB cords usually without any interference.

The entire device is backup-protected with a Type 3 SPD (Surge Protective Device) to keep USB-connected devices safer while also reducing the risk of surge damage caused to appliances plugged into the power outlets. Under non-lightning surge events, the surge protector will disable the voltage flowing to any of the power ports. In the event of a surge, the entire unit must be replaced, so we offer an inexpensive replacement option to help you get charging stat.
