Neravo E1 is a compact 270 ml hydrogen water bottle built around clear, repeatable operation. It combines 5- and 10-minute timed cycles, a front digital display, a detachable production base, Type-C charging, and compatibility with selected 28 mm water bottles.

• Two timed cycles: select a 5- or 10-minute operating cycle from the physical start control.
• Front digital display: view the selected cycle, remaining time, and battery status.
• Detachable construction: separate the 270 ml cup body from the production base for handling and care.
• Compatible bottle mode: connect the base to a compatible 28 mm water-bottle mouth when the E1 cup body is removed.
• Pressure management: the cover includes a pressure-relief vent, while the production base includes an exhaust vent.
• Type-C charging: charge through the Type-C connection using the included cable and a suitable DC 5 V / 1 A power source.

Two defined operating cycles

Long-press the front start control for three seconds to begin operation. Short-press the control to choose the 5- or 10-minute cycle. The E1 stops automatically when the selected cycle is complete and can also be stopped manually with a long press.

Compact 270 ml format

The E1 measures 61 mm in diameter and 230 mm in height. Its narrow black format combines a clear 270 ml chamber, front display, physical control, and a short detachable production base.

Detachable cup and compatible bottle mode

For standard operation, attach the cup body securely to the production base. The base may also be connected to a compatible 28 mm water-bottle mouth after the E1 cup body is removed. In compatible bottle mode, leave approximately 2 cm of headspace below the bottle mouth and keep operation within ten minutes.

Compatible 28 mm bottle not included.

3. Secure the cover, then long-press the start control for three seconds.
