FEATURES
Safely charge any laptop.
The ARROE mobile app and the firmware on the LAER device can customise the
voltage and current output of the battery to match the device it is charging. This is
particularly important when charging laptops which all charge at different
voltages. Other power banks output set voltages (i.e. 12/16/19V) which do not
match the voltage inputs on most laptops. This means that the charging of a
laptop/Microsoft Surface device at these set voltages results in permanent
damage of the laptop battery and also potential damage to the laptop’s circuitry.
The LAER device is the first portable battery that can safely charge any laptop
including Microsoft Surface.

ARROE SOFTWARE/FIRMWARE
Our database
Our database in the cloud stores battery and voltage information necessary to
safely charge any device (initially focused on laptops). Laptop profiles containing
voltage and current information by laptop manufacturer and model are stored in
the cloud, downloaded automatically from the virtual server and stored locally on
the ARROE app.
Power management algorithm
The power management algorithm which has been devised by ARROE permits the
continuous assessment of available power so that the LAER device can route the
correct amount of power to the correct port at the correct time and at the correct
voltage. This enables LAER to charge multiple devices at different voltages
simultaneously.
OCR technology
If a laptop profile is not present within the database, the user can also submit new
laptop profiles by using the ARROE app’s optical character recognition (OCR)
function. This software intelligently scans the DC properties (voltage, current and
power) from the AC/DC power adaptor of the user’s laptop.
6
Bluetooth 4.2.
Using the ARROE app, LAER can communicate with mobile applications on
personal electronic devices (PEDs) such as smartphones and tablets using
Bluetooth 4.2 technology. This feature also permits the user to perform Over The
Air-Device Firmware Upgrades (OTA-DFU), which are applied to the updatable
hardware, enabling improved performance over time.
Battery Management System / Protection Circuit Module
The LAER battery cartridge consists of a 14.8 V 74Wh battery pack. The cartridge’s
Battery Management System (BMS) communicates with LAERs printed circuit
board assembly (PCBA) via its battery connector pins.
7
The LAER PCBA communicates with the cartridge BMS to confirm the authenticity
of the cartridge, along with the batteries other properties such as state of charge,
battery capacity, temperature, voltage, current and impedance. The advanced
BMS allows LAER to calculate the number of charge/discharge cycles experienced
by each individual battery, battery health and the degree of aging over time. This
information is collected and stored on our database along with the user’s
charging profile and habits. This information gives ARROE a way to greatly improve
the user’s charging experience by keeping us informed of individual battery usage
and performance.
The top end of the cartridge displays a battery connector pin system while the
bottom end of the cartridge displays 2 keepers (open/close mechanism). This is
accompanied by a centre cartridge pull recess for easy removal. Every cartridge
also possesses a visual display system which can communicate the Battery State
of Charge (%) when the battery cartridge is ejected from LAER. This system utilises
4 white LEDs (1 LED on (0-25%), 2 LEDs on (26-50%), 3 LEDs on (51-75%), 4 LEDs on
(76-100%)). The LEDs are activated via a small mechanical button positioned on the
battery cartridge and can be activated when the cartridge is not inserted into
LAER.
SAFETY
The safety of the user is essential. The BMS possesses cell balancing during
charge/discharge, overvoltage protection, overcurrent protection, over discharge
protection, high temperature protection and low temperature protection, among
many others.
The cartridge also contains two stainless steel (SUS304) metal plates which are
secured to the internal casing wall of all battery cartridges. The plates cover the
battery pack inside to prevent perforation and other methods of damage,
therefore dimensions are approx. 180×158 mm (or have a slightly larger surface
8
area than the face of the battery pack). The cartridge also contains sponge mat
to allow for expansion and swelling (5-10%) of the cells during cycling.
