How do I charge the NIRA Laser?Updated 11 hours ago

The NIRA Laser uses a built-in battery.

Each device comes with a charging cord. The cord has a small end (USB-c) and a large end (USB-a). The small end plugs into the device for charging. The large end plugs into a wall adapter.

Adapters are sold separately. However, most smartphone charging blocks work, as well.

The device is worldwide voltage compatible. You can charge it overseas.

In general, carry it onto a flight. Do not pack it in your checked baggage.
