Simultaneous Data Transfer and Charging

SimulCharge™ is a mode uniquely innovated by LAVA that allows portable devices such as tablets or phones, to charge while simultaneously interacting with USB accessories


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 charging and access to data to compatible
Samsung and Lenovo mobile devices

The technology works with select USB-C and Micro USB devices and our adapters have various port 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 any peripherals attached to the adapter and a network connection (if applicable).

Home Series

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

They can be used for adding wired Ethernet and/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.

Enterprise Series

LAVA’s Enterprise Series are versatile mobile adapters designed to be used by businesses in permanent and semi-permanent installations, such as tablet-based kiosks, digital signage or staff time clock applications.

Many of these adapters come with additional technologies, such as Battery Modulation (overcharge protection) to extend the mobile device’s lifespan, Network Recovery to provide a reliable wired connection and Docking Detect for permanent and portable kiosk applications.

A World of Peripherals

With Simulcharge™ your tablet can open up a world of possibilities by supporting USB accessories such as:

  • Wired Ethernet
  • NFC Reader
  • MagStripe Reader
  • 2D Scanner
  • Biometric Input Device
  • GPS Tracker
  • Printer
  • Scale
  • Digital Camera
  • Pulse Counter
  • USB-to-Serial Adapter
  • Momentary Switch (button)
  • Keyboard/mouse
  • USB Hard Drive
  • Flash Drive
  • Media Reader
  • Gaming Controller

Powering Up

Keep your tablet fully charged and functional, while deploying the USB accessories of your choice.
LAVA adapters are available in 3 power options:

Home Series products have a 5-volt power input that allows 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.
