Type: Rechargeable, personal-use device

What is emGuarde™?

emGuarde ™ is a compact, rechargeable device designed for personal use to help suppress targeted electromagnetic noise in everyday environments such as homes, offices, and during travel.

It works quietly in the background and does not affect normal device usage.

 emGuarde™ helps suppress targeted high-frequency electromagnetic noise, creating a more balanced and comfortable electromagnetic environment.

It does not block, jam, or disconnect electronic signals.

 emGuarde™ uses harmonic frequency technology designed to act on high-frequency electromagnetic noise within the range of 3 MHz to 1000 MHz.

It operates at a low, fixed power level of 0.5W.

 emGuarde™ generates harmonic frequencies that continuously and passively suppress targeted electromagnetic noise in the surrounding environment.

No setup or adjustment is required, and it does not interfere with Wi-Fi, mobile networks, or Bluetooth.

 emGuarde™ provides coverage within a 1.5-meter radius (approximately 3 meters in diameter), suitable for personal or close-range use.

Yes. emGuarde™does not interfere with:

  • Mobile phone signals
  • Wi-Fi connections
  • Bluetooth devices

You may continue using electronic devices normally.

No. emGuarde™ does not block or shield signals.
It is designed to suppress targeted electromagnetic noise only, while allowing normal communication signals to function as intended.

Yes. emGuarde™ has a built-in rechargeable lithium-polymer battery.

  • Battery capacity: 5000 mAh
  • Charging input: DC 5V, 2A (fast charging)

Under normal usage, a full charge allows emGuarde™ to operate for up to 72 hours.

Actual battery life may vary depending on usage. For example, frequently pressing the power button to check the LED indicator will consume additional power and may shorten operating time.

Yes. emGuarde™ can be used while charging.

No. Fast charging only affects charging speed.

 emGuarde™ operates at a fixed power output of 0.5W. Coverage and performance are determined by the device design, not by charging current.

 emGuarde™ is designed for everyday carry:

  • Net weight: 175 g
  • Dimensions:
    • Width: 73.6 mm
    • Length: 154.4 mm
    • Thickness: 14.2 mm

It fits easily into a bag or backpack.

 emGuarde™ can be used in many everyday situations, including:

  • At home
  • In offices
  • While travelling
  • In cars or trains
  • In personal working or resting spaces

Yes, subject to airline regulations.
Please ensure emGuarde™ is switched off during takeoff and landing.

No routine maintenance is required.
Simply keep the device clean, dry, and protected from physical damage.

No.

  • emGuarde™ is not waterproof
  •  emGuarde™ is not drop-proof

Please handle the device with care.

emGuarde™ is designed for long-term use.
The built-in lithium battery is designed to last approximately 2–3 years under normal usage before you may notice shorter operating time.

Battery lifespan may vary depending on:

  • Usage habits
  • Charging frequency
  • Environmental conditions
  • Operating or storage temperature

Like all lithium batteries, natural capacity reduction over time is normal and does not affect safety or device functionality.

 emGuarde™ uses a high-quality 5000mAh lithium-polymer battery that complies with UL safety standards.

UL stands for Underwriters Laboratories, an internationally recognised safety certification organisation.

A UL-compliant battery means it has passed international safety testing standards for lithium batteries, including electrical and thermal safety.

The battery supports hundreds of charging cycles.

With normal usage (such as charging every 2–3 days), it typically provides 2–3 years of reliable operation.

No. Battery aging may result in shorter operating time, but it does not affect device safety or emGuarde™’s core function when used under normal conditions.

No. emGuarde™ is not a medical device and does not diagnose, treat, or cure any medical condition.

It is designed for personal environmental support only.

 emGuarde™ comes with a 1-year manufacturer warranty.
