The Nitecore NWE10 is an ultra-compact electronic emergency whistle designed to generate a powerful acoustic signal of up to 126 dB without the need to blow into it.

It is designed for trekking, hiking, trail running, camping, mountaineering, boating, travelling and emergency kits, where it may be essential to quickly attract attention or signal your position even in conditions of fatigue, cold or physical difficulty.

Unlike a traditional whistle, the NWE10 generates its signal electronically: simply operate the power button to produce a powerful and repeatable acoustic signal, without using physical energy by continuously blowing into a whistle.

Acoustic output up to 126 dB

Despite its extremely compact dimensions, the Nitecore NWE10 can reach a declared sound pressure level of up to 126 dB.

The powerful acoustic output is designed to increase the possibility of being detected from a distance and provides valuable support in situations where your voice may not be sufficient or cannot be used for long periods.

Single and continuous acoustic signal

With the device switched off, a brief press of the button produces a single acoustic signal.

Holding the button down activates the continuous acoustic signal, which stops when the button is released.

This mode allows you to immediately attract attention while directly controlling the duration of the signal.

Automatic SOS mode

By holding the button down for approximately 10 seconds, the NWE10 automatically enters SOS mode.

The device then switches from the continuous signal to an automatic intermittent acoustic sequence, repeated approximately every 3 minutes.

This function is particularly useful in an emergency because it allows the device to continue signalling automatically without requiring the user to constantly hold down the control.

Beacon mode

During SOS operation, it is possible to switch to Beacon mode, providing an additional signalling mode designed to help locate the user.

No need to blow

One of the main advantages of the Nitecore NWE10 compared with a conventional whistle is its fully electronic operation.

In an emergency situation, after many hours of walking or in conditions of cold, stress or fatigue, repeatedly blowing into a whistle can become difficult.

With the NWE10 you simply press a button: the electronics generate the acoustic signal for you, reducing the physical effort required to continue attracting attention.

Up to 80 hours runtime

The built-in Li-ion battery provides a declared runtime of up to 80 hours, an especially important feature for a device intended for safety and outdoor use.

To keep the battery in good condition during long periods of inactivity, Nitecore recommends periodically recharging the device.

USB-C charging

The NWE10 features a modern USB-C port and can be recharged using compatible chargers, power banks and other USB power sources.

Charging input is 5V / 1A and a full recharge takes approximately 2 hours when using a compatible power adapter.

The device can also be used while charging.

Battery level indicator

Four indicator lights allow you to quickly check the remaining battery capacity:

• 4 indicators on: 76% - 100%
• 3 indicators on: 51% - 75%
• 2 indicators on: 26% - 50%
• 1 indicator on: 0% - 25%

When only one indicator remains illuminated, it is recommended to recharge the product as soon as possible.

Compact and lightweight

With dimensions of approximately 65 x 33 x 32 mm and a weight of only 38 g, the Nitecore NWE10 can easily be added to personal equipment without significantly increasing weight or bulk.

It can be carried in a backpack, trekking equipment, an EDC kit, a vehicle or any emergency preparedness kit.

Nitecore NWE10: small enough to carry, powerful when needed

The Nitecore NWE10 reinterprets one of the simplest and most traditional outdoor safety tools, transforming it into a modern, rechargeable electronic device equipped with automatic signalling modes.

126 dB sound output, only 38 grams, SOS and Beacon modes, up to 80 hours runtime and USB-C charging make it an extremely interesting accessory for outdoor enthusiasts or anyone wishing to add a simple and immediate emergency signalling device to their equipment.

A device that takes up very little space and that you hopefully never have to use in a real emergency, but which can become extremely important when you need to make yourself heard.
