EVOLVEO StrongPhone Z4

The next new product in the EVOLVEO range of durable telephones follows its successful predecessor, the StrongPhone Z3 model, bringing many new advantageous features.

The resilient and rugged StrongPhone Z4 is the best choice for everyone who wants more from their phone. The durable body with IP68 certification can handle impacts and environmental effects without a problem. The outdoor Z4 phone is equipped with a large and perfectly legible 2.8" IPS LCD display. Thanks to its generous 2500 mAh battery, it offers a power bank function. It also has an SOS button and charging station. All of the above make the telephone a universal solution when working at the workshop, construction site, in challenging environments, during freezing cold or very hot weather, or in humid environments.


Large 2.8" IPS screen

The StrongPhone Z4 rugged mobile has a 2.8" IPS screen. The IPS technology also provides realistic rendering of colours, a wide range of viewing angles, and low power consumption. Increased durability against scratches and pressure allow you to use the phone under any circumstances.

2500 mAh battery/power bank

The modern, high-capacity Li-ion 2500 mAh battery can power your phone for up to two weeks. In addition, you can use its capacity to charge your other devices. The StrongPhone Z4 rugged mobile has a power bank function which allows you to utilise the extra battery capacity.

SOS calls and SMS
The outdoor EVOLVEO StrongPhone Z4 has an SOS button, enabling you to easily get help in case of emergency. Pressing the button automatically dials preset numbers and sends a SOS text message.


Multimedia accessories

Among the features of the durable phone is a 2 Mpx camera, powerful LED flashlight and FM radio with an integrated antenna and automatic station tuning. You can also use the calendar, alarms, or calculator.

Charging stand

To make the charging process easier, we have equipped this model with a charging stand, which ensures easy charging with no need to connect a USB cable to the phone.

Waterproof telephone IP68
