Even in the field.
MOBIOLA MB520 TitanX is a rugged feature phone with equipment you won’t easily find elsewhere. Thanks to its 6000 mAh battery, it becomes a true endurance champion — on construction sites, trips, at work, or at the cottage. And when someone else runs out of power, you can easily help — the MB520 also works as a power bank.

The phone features dual durability certification IP68 and IP69K, allowing it to withstand water, dust, mud, and even high-pressure cleaning. The rubberized construction and solid body provide reliable protection in the most demanding conditions.
An SOS button is located on the back of the device for added safety. When pressed, it can automatically call up to five preset numbers and send them an SMS message.
The MB520 features a 2.8” IPS display that is bright and easy to read even in direct sunlight. The phone is robust yet comfortable to hold, with large, precise, and backlit buttons. Two powerful LED lights are positioned on the top, replacing a traditional flashlight — ideal for workshops, tents, or power outages.
With its 6000 mAh battery, the MB520 lasts for several days without the need for charging. Thanks to the included USB-C to USB-C cable, it can also be used as a power bank — allowing you to charge headphones, a headlamp, or another phone.
The phone features a 2 MP camera with video recording, a file manager, music and video player, FM radio (no headphones required), and a voice recorder. It offers 48 MB RAM and 128 MB ROM, expandable via a microSD card up to 128 GB. You can also use 2× nano SIM cards and a microSD card simultaneously.
The MB520 supports 4G networks and VoLTE, delivering high-quality calls without interruptions. Thanks to Bluetooth 5.0, you can connect wireless devices, and the 3.5 mm jack allows the use of standard wired headphones. The phone features a USB-C connector and a loud speaker.
