Simultaneous Power & Data

A technology innovated by LAVA, SimulCharge™ enables tablets and smartphones to interact with USB accessories while the device is charging.

Want to use wired peripherals while your tablet is charging?

Mobile devices can operate in either USB Host or Target mode. When it is in Host mode, it is the primary device and is able to control peripherals attached and access a wired network connection (if there is one). However, when it is charging, it switches to Target mode, with the Host being the power source. In Target mode, the mobile device loses access to data. This means you generally can’t use peripherals while the mobile device is charging.

Our Solution

SimulCharge™ provides simultaneous power & data to compatible mobile devices.

SimulCharge™ adapters come in a variety of power options and configurations, including Ethernet and multiple ports for USB-enabled peripherals. With a LAVA SimulCharge™ adapter, tablets and smartphones can be used in kiosks, digital signage and other mobile device-powered applications.

How SimulCharge™ Works

A LAVA SimulCharge™ adapter allows the mobile device to remain in USB Host mode while plugged in through its USB port. The mobile device is able to charge from a power source, while maintaining access to a network connection (if applicable) and any peripherals attached to the adapter.

Enterprise Series

LAVA’s Enterprise Series are versatile adapters designed for business use in permanent and semi-permanent installations, such as tablet-based kiosks, digital signage or staff time clock applications.

Many of our adapters come with additional technologies, such as Battery Modulation for robust battery protection, Network Recovery to provide a reliable wired connection and Docking Detect for permanent and portable kiosk applications.

Home Series

LAVA’s Home Series SimulCharge™ adapters are compact, portable and designed for personal use.

Use them to add wired Ethernet or USB peripherals to your mobile device, giving it more functionality. They also feature an OTG mode so they can be used without a separate power source and be powered by the mobile device.

Powering Up

Whether you need power at a distance, in a car, over Ethernet (PoE), or more... you've got options.


Units with a 5-volt power input allow the mobile device to be up to 6 feet (2 meters) away from the power supply. This is the standard power option for mobile devices. Any regulated 5-volt, 2-amp (DCP-capable) power supply can be used. Though, it is recommended you use the charger that came with the mobile device.

Voltage Converter (9-36V)

Voltage converter units allow the adapter to be placed up to 50 feet (15 meters) away from the AC power source. The adapter features a Barrel Jack port for a DC power supply. The built-in voltage converter allows the adapter to receive an input voltage between 9 and 36 volts and steps it down to a device-friendly 5 volts for use with the mobile device. They are ideal for automotive or battery-based applications. The low DC voltage also allows these adapters to operate in permanent and semi-permanent installations while being fully compliant with local electrical codes. This eliminates the expense of hiring an electrician and the requirement of dedicated AC cable routing and installation.

Power Over Ethernet

Power over Ethernet provides up to 10.4 watts of power and wired network connectivity over the same Ethernet cable. LAVA’s PoE SimulCharge™ adapters can be installed up to 328 feet (100 meters) away from the power source. You don’t need to hire an electrician as the installation does not involve electrical cables going into an AC power source. If there is no PoE-capable network switch, you can invest in a third-party PoE injector, which can turn a regular LAN connection from a modem or router into PoE.
