1How far away can I place my mobile device from the LAVA unit?
The mobile device can be located up to 1 meter (3.3 feet) away from the LAVA unit.
In some cases the mobile device may be placed up to 1.25 meters (4.1 feet) away from the LAVA unit, but great care must be taken to ensure that sufficient power is being supplied to the mobile device. A power budget and use of LAVA’s Battery Info app is recommended before deployment of the 1.25 meter cable. Do not extend cables beyond 1.25 meters.
OEM and BM-OEM boards should not be used with cables longer than 20 centimetres (8 inches) as the resulting power loss will lead to unreliable device charging and operation.
Available cables for the STS and LTS product families are 20cm (8”), 1m (3.3ft) and 1.25m (4.1ft).
Available cables for the Sync product families are 20cm (8”) and 1m (3.3ft).
Note: The STS and LTS product families use custom cables and cannot be replaced with off the shelf cables. Off the shelf cables will prevent proper unit operation (SimulCharge).
2By how much can I extend the “to tablet” cable?
Do not extend the “to tablet” cable. Extension of this cable will introduce further power losses into the system that may result in improper mobile device charging and operation.
“Daisy Chaining” of cables will result in the mobile device being unable to operate in SimulCharge mode and may also lead to improper charge (introduction of power losses in connectors).
3What lengths of cable are available for the "to tablet" connection?
The Micro USB cables come in 4 lengths:
- 20 cm (8”)
- 50 cm (20”)
- 100 cm (39”)
- 125 cm (49”)
The most common cables used are the 20 cm (8”) for the OEM and BM-OEM units and the 100 cm (39”)
The USB-C cables come in 2 lengths:
4What standard or standards does LAVA support for wired networking?
Ethernet enabled LAVA products provide 10/100 Fast Ethernet capabilities. The Ethernet feature relies on standard support available on the mobile device.
5Can I make my own “to tablet” cable?
No. The Micro USB cable supplied is a custom cable designed to decrease the power loss of the cable as well as allow the mobile device to enter SimulCharge Mode.
It is not advisable to create your own USB C cable as all pins need to be used in order to operate in Simulcharge Mode.
6What if I need to place my mobile device 3 meters away from the LAVA unit?
This is not an option. You will need to have your LAVA unit within 1 meter (maximum 1.25 meters in some cases) of the mobile device.
Please see “How far away can I place my mobile device from the LAVA unit?” FAQ for a more in depth explanation of why this is not an option.
7How far can my LAVA unit be from the USB Power Brick?
The distance is restricted by the length of the mobile device provided power cable (3 ft.).
8Can I extend the cable used to connect my mobile device to the USB Power Brick?
No. It is essential that you use the mobile device supplied power cable as the supplied power brick is able to compensate for power losses in that cable. This ensures that a stable 5 volts are supplied to the LAVA unit.
If your application requires that the LAVA unit be placed farther away from the AC power source, then the VC or PoE equipped LAVA units should be considered/used.
9Can I use a USB Power Brick other than the one supplied with the mobile device?
This is not recommended, as power bricks come with different ratings and are matched to each mobile device. This ensures that sufficient power is supplied to the mobile device.
10Can I use a USB Power Bank with my LAVA unit?
Yes you can. You will have to make sure that the power bank (USB Battery Pack) is capable of supplying 5 volts, preferably at or above 1 Amp (1000mA). If the power bank is not capable of supplying such a high current at 5 volts you may see the mobile device slowly discharge as it is receiving insufficient current.
11Can I use a USB “Cigarette Lighter” type adapter with my LAVA unit?
Yes, but you will have to ensure that the adapter is capable of supplying more than 500 mA at 5 volts through a USB A port.
12What if I want to run my mobile device and LAVA unit from a 12 Volt power source?
You will need to purchase a LAVA adapter with the VC option included. The VC option includes a built in voltage converter that is able to step down the 12 volt input to the require 5 volts. The VC option units draw power through a 2mm center positive barrel plug connector. Power supply is sold separately.
13What do I do if the AC wall outlet is between 3 meters (10 feet) and 15 meters (50 feet) away from the LAVA unit?
You will need to purchase a LAVA adapter equipped with either the VC option or PoE. For VC units a higher voltage (up to 36 volts) is required the further away the LAVA unit is from the AC power source. The higher voltage will compensate for the power loss over the power line.
14What do I do if the AC wall outlet is more than 15 meters (50 feet) away from the LAVA unit?
You will need to purchase a LAVA adapter equipped with PoE. Please note, PoE is rated for distances up to 100 meters (328 feet).
15What is PoE?
PoE stands for Power over Ethernet and is an industry term/standard that allows devices to draw power, along with data, through standard Ethernet cabling. Power is low voltage DC with a maximum transmission distance of 100 meters (328 feet). PoE can be applied through PoE capable network switches or through add-on PoE injectors that apply power to the existing Ethernet cable and network.
PoE is an excellent power and data alternative for large installations that are located far from existing AC power sources, as PoE’s low voltage category does not require licensed electricians to install the required infrastructure.
All PoE capable LAVA units are marked with a letter “P” in their name (ex/ eSTS PE).
16What PoE standards do you support?
The Ethernet Port is an IEEE 802.3 100BASE-T / 100BASE-TX compatible Fast Ethernet interface. The Ethernet port on PoE capable LAVA units accepts a standard RJ45 connector.
17Why would I want to use PoE?
The PoE Ethernet Port has the ability to receive power from the Network Cable. All power for the LAVA unit, mobile device charging, and attached USB accessories are provided by the PoE-Ethernet Port.
PoE capable LAVA products resolve the problem of getting power to the mobile device and peripherals. The PoE specification allows the powered device to be up to 330 feet (100 meters) from the Network Switch or PoE Injector.
Deploying network cabling with PoE support can be significantly cheaper than installing dedicated power lines through a facility.
18What if my network switches do not support PoE? Do I have to replace all the switches?
Non PoE capable Network Switches can use a PoE Power Injector, for each port, to supply power over the existing network cable/port. PoE injectors are cost effective solutions for installations that do not want to replace non PoE capable switches. PoE injectors can be found at most network switch vendors or electronics suppliers.
19How much power is available for my mobile device when using LAVA PoE capable devices?
The LAVA unit is supplied with 10.4 Watts of power, which is then divided to supply power for the mobile device, LAVA unit and attached peripherals. The 10.4 Watt limit allows the LAVA unit to be treated as a PoE Class 0 device by the switch.
20Can I use PoE to provide power to my tablet when not using Ethernet data?
Yes you can. However, you will have to disable the Ethernet option on your mobile device.
21What is the maximum distance I can place my LAVA unit from the wall outlet, when using VC?
15 meters (50 feet). It is strongly recommended that a 24v or 36v power supply is used.
22What is the maximum distance I can place my LAVA unit from the switch, when using PoE?
100 meters (328 feet). If using a PoE injector to pass power then the distance is from the power injector and not the switch.
