The DefenderShield Laptop EMF Radiation & Heat Shield is the world’s leading laptop radiation protection pad, designed to block potentially harmful electromagnetic fields (EMFs) and reduce heat exposure to your lap during laptop use.
Laptops emit multiple forms of wireless radiation, including Wi-Fi and, Bluetooth, as well as cellular signals for newer, broadband-enabled laptops. Additionally, the battery and power being used by your laptop leaks energy, called ELF (Extremely Low Frequency), that can increase radiation and concentrated heat exposure to sensitive areas of the body. For online workers, students, gamers, and anyone who spends long hours on laptops, this daily exposure adds up.
The DefenderPad addresses this problem by using Ultra Armor+ shielding technology, proven to block up to 99% of EMF emissions across the widest range of frequencies from 0–90 GHz. At the same time, an integrated silicone thermal barrier in the Standard DefenderPad prevents direct heat transfer, ensuring comfort and reducing risks associated with extended device usage.
Engineered for convenience, the DefenderPad is lightweight, slim, and easy to carry. Its non-slip surface keeps laptops stable, while its universal size works with all handheld devices up to 17". The DefenderPad Lite is suitable for devices 15” and smaller. Unlike bulky alternatives, it blends seamlessly into your daily routine without interfering with laptop performance. This design balances protection and usability, powerful shielding where you need it, without limiting connectivity or device function.
Please note: The DefenderPad shields EMF and heat directed downward toward your lap but does not block emissions that radiate outward into the room. For comprehensive protection, the DefenderPad can be paired with other DefenderShield products.
Many customers use it alongside our EMF Radiation Blocking Blanket, EMF Protection Shorts, or Blue Light Blocking Glasses to reduce the potentially harmful effects of laptop use.
