StrongPhone W4 is the best choice for those who expect something extra from their phone. The durable device housing with IP68 certification, the large and easy-to-read 2.8-inch IPS LCD display, the power bank function, the SOS button or the large 2500 mAh capacity provide a versatile solution for work in the workshop, on construction sites, in the field, in extreme cold or, on the contrary, in high temperatures and humidity. The phone does not mind water, mud, snow, dust and rough handling.

Brilliantly readable 2.8" display

One of the main advantages of the StrongPhone W4 is its large 2.8-inch IPS display, which has increased scratch and pressure resistance. IPS technology provides realistic color rendering, wide viewing angles and low power consumption. This makes it easier to use the phone in any conditions.

2,500 mAh battery with power bank function

The 2500 mAh battery will keep the phone going for up to two weeks and a bit more. The durable StrongPhone W4 is equipped with a powerbank function that allows you to use the battery capacity to charge other devices.

SOS call and SMS alarm

StrongPhone W4 is equipped with an emergency SOS button to call for help in case of danger. When the button is pressed, the phone automatically dials the preset numbers and sends them an emergency message.

Multimedia equipment

The robust phone has a 2 megapixel camera, a powerful LED flashlight or a built-in FM radio with a built-in antenna and automatic station tuning. Other functions include a calendar, alarm clock or calculator.
