Solvian Dual Port 4.2A LED USB Charger

Solvian Dual Port 4.2A USB Charger with Voltmeter

A functional panel charger with two 5V USB ports and a built-in LED voltmeter. Designed for installation in vehicles, campers, boats, and off-grid systems, it provides fast charging of mobile devices and constant 12-24V system voltage control.

Dual USB charger with voltmeter

The Solvian charger has two 5V USB ports with total output current up to 4.2 A, which allows you to charge two devices simultaneously, such as:

• smartphones and tablets,


• GPS navigation,


• sports cameras and driving recorders,


• LED lighting and small electronics.

Built-in blue LED display shows the current voltage of the installation, which allows you to constantly monitor the condition of the battery and the entire power system.

High resistance for Auto/Marine applications

The charger housing is made of durable material, resistant to:

• moisture and splashes,


• vibrations and shocks occurring in vehicles and boats,


• variable operating conditions in campers and mobile installations.

This makes the device ideal for demanding Auto/Marine environments and off-grid systems.

Easy installation in installations

The universal design of the charger allows simple panel installation in:

• passenger cars and vans,


• campers and expedition buildings,


• boats, yachts and vessels,


• quads, off-road vehicles and 12-24 V off-grid systems.

This DIY solution allows you to easily add a practical charging socket and voltmeter wherever you need it most.

Rubber protective flap

The charger is equipped with rubber protective flap which protects:

• USB ports against water and moisture,


• the interior of the socket against dust and dirt,


• connectors against accidental mechanical damage.

This is particularly important in Auto/Marine and off-road applications where electrical equipment is exposed to harsh environmental conditions.

Threaded mounting body

enables quick and stable installation of the charger in panels:

• vehicle dashboards,


• control panels in campers and boats,


• boxes and distribution boards of 12-24 V installations.

The lock nut ensures a secure fit, ensuring the charger remains stable even under heavy vibrations and shocks.

Main features
