How to Charge a Rechargeable White Noise Machine

Use the Nodiee Cable

Only use the Nodiee USB-C charging cable supplied with your machine. Other cables may damage the charging port or lithium-ion battery and may void your warranty.

Use a 5V = 1A (5W) Adapter

Connect the cable to a certified wall adapter with an output of 5V, 1A (5W). In Australia, look for the Regulatory Compliance Mark (RCM).

Keep 1 Metre from the Cot

Always charge your white noise machine at least 1 metre away from your child’s cot, bassinet or sleeping area. Keep the machine and charging cable safely out of reach.

Place on a Flat Surface

Place the machine on a stable, hard surface with clear airflow. Do not charge it on a bed, couch or under fabric where heat can build up.

When to Replace Your Cable

Over time, charging cables naturally wear down. Replace your cable if you notice:

  • Fraying, bending, or exposed wires
  • Loose or wobbly connector ends
  • The cable feels very hot to touch
  • You are still using the original cable from before May 2024

We have introduced a stronger, more durable cable with reinforced connectors and added safety features. If eligible, you can claim a complimentary upgrade today.
