Know before you buy
The integrated FLIR Lepton 3.5 sensor allows you to visualize heat signatures directly on your screen. It is highly effective for professional tasks like identifying electrical hotspots, detecting heat leaks in insulation, or locating pipes behind walls.
While the large battery adds some heft to the device, it provides significant longevity, often lasting multiple days with moderate use. With the included 66W fast charger, you can replenish a substantial portion of that capacity in under an hour.
The device features Corning Gorilla Glass 5, which offers solid protection against everyday drops and surface scratches. While it is highly resilient, it is still recommended to avoid direct impacts on hard surfaces to maintain the screen's integrity.
The Power Armor 18T supports dual SIM functionality, allowing you to manage two numbers at once. You should check the specific tray configuration, as many rugged phones use a hybrid slot that requires choosing between a second SIM or expandable storage.
A 120Hz refresh rate provides a smoother visual experience, which does consume more power than a standard 60Hz display. However, given the massive 9600mAh battery, the impact is manageable, and you can always toggle the refresh rate to 60Hz in settings if you need to maximize runtime.
An IP68 rating means the phone is fully protected against dust ingress and can withstand submersion in water up to a certain depth—typically 1.5 meters—for up to 30 minutes. It is designed for harsh environments, but it is not intended for high-pressure water jets or prolonged deep-sea diving.
