SimulCharge™, Voltage Converter, 3 x USB Adapter with RBM Technology for Samsung Micro USB Mobile Devices

$89.99 / Web Price

The eSTS-vc3U provides compatible Samsung Micro USB mobile devices* with SimulCharge™, a built-in voltage converter and three USB-A ports for peripherals. SimulCharge™ ensures the mobile device can simultaneously access any USB peripherals attached to the adapter while it is charging. The adapter also features RBM technology.

RBM’s Battery Modulation protects the mobile device’s battery from constant overcharging, which can degrade the battery over time and shorten its lifespan

The eSTS-vc3U can use an external DC power source, ranging from 9 to 36 volts. The DC-DC converter steps down the input voltage to a device-friendly 5 volts for use by the eSTS-vc3U and mobile device.

How the eSTS-vc3U Works

The eSTS-vc3U adapter provides compatible Samsung Micro USB mobile devices* with simultaneous charging and access to data (SimulCharge™). It features a built-in voltage converter, three USB-A ports for peripherals and RBM technology.

The eSTS-vc3U’s on-board DC-DC voltage converter can take a power input of between 9 and 36 volts** and steps it down to the 5 volts required by most mobile devices***. The adapter can be used to supply power in permanent and semi-permanent installations (adhering to local electrical codes) with minimal installation cost. This eliminates the requirement for a licensed electrician to install and run a dedicated AC power line.

Power at a Distance

The adapter can also be installed up to 50 ft (15 m) from the AC power source. This means it can be installed in locations with limited electrical outlets and provides greater options for mobile device placement.

The eSTS-vc3U’s USB-A ports allow you to connect up to three peripherals, such as a scanner, printer and card reader for a tablet kiosk setup.

Robust Battery Protection

Battery Modulation protects the mobile device from overcharging and its battery from bloating, which can cause severe damage to the device.


The LAVA Tablet Manager (LTM) app, installed on the mobile device, monitors the battery level and users can set upper and lower charging thresholds for the battery. When the battery charges to the higher threshold, the adapter turns off charging and the mobile device is allowed to discharge until it hits the lower threshold. This ensures the battery never overcharges, even if it is left plugged in 24/7. Battery Modulation extends the lifespan of both the battery and device for a better return on investment.

Other Features

RBM also features Screen Brightness Management, which lets customers set a daytime and night-time brightness level through the LTM app, as a way to combat overheating. This allows for the mobile device to have a bright display during the day when the business is open and a dimmer display at night after it closes. The display is one of the biggest sources of heat for a mobile device. Excess heat puts additional strain on the battery and can also accelerate battery bloating. Dimming the display during off-hours significantly reduces its heat generation, prolonging the lifespan of the device.

The adapter comes with a casing and a Micro USB to Micro USB cable to connect the mobile device. This custom LAVA cable must not be extended or replaced with a third-party one. Doing so will cause the mobile device to stop working.

*The eSTS-vc3U is not compatible with all Samsung mobile devices. Please see the list of tested Samsung devices.
**The 9-36V DC power supply is not included with the adapter and must be purchased separately.
***The mobile device can also be powered through the adapter’s Micro USB-B port, which is rated for the standard 5 volts at 2 amps. It is recommended to use the charging cable that came with the mobile device. A separate power supply is not included.
