1. The Changers Kalhuohfummi –
an introduction to your solar battery
Hello and welcome! You’ve just taken your first step towards becoming a Changer, and are about to start making the
world a better place through the power of solar energy. At the heart of what we do is a belief in the ideas of sustainability
and responsible living, and our products are an extension of this philosophy.

04Introduction to energy tracking | Content and compatibility
The Kalhuohfummi is engineered to do considerably more than just store energy. It can
accurately tell you how much solar power you are generating, how much you have stored up,
and keeps a constant log of both your energy production and COsavings. When connected to
our community at www.Changers.com, the Kalhuohfummi becomes the portal to our system
of awards and rewards. Once you have created an account on our website, simply connect the
device via USB, track your savings and start sharing your information.
2. Introduction to energy tracking
The Kalhuohfummi provides portable power for a large range of mobile electronic devices, including smartphones, tablets,
portable GPS systems and portable game consoles. The electrical energy that comes through the Maroshi panel is stored in the
battery, and can then be used to charge your devices – anyplace, anytime.
Your package includes:
x Kalhuohfummi solar battery
x USB data cable with USB type A connector and micro USB connector
x USB charging cable with USB type A connector and DC jack
x Quickstart poster

second shows how many watts of electricity you produce (for example  blinks per second
means  watts power of the solar module). In general, the higher the ash frequency, the
more power that is generated by the solar module. Below a power of ⅓ watt LEDs ashes
constantly once every three seconds. Depending on the battery capacity the corresponding

08Four steps to solar sharing
In principle, it is possible to connect any solar module that meets the technical specications in
Chapter  to the battery. However, we recommend the use of Changers solar panels.
• Plug the DC plug of the solar module into the  input jack.
• Make sure that the solar module is securely mounted by the included suction cups
or other tools. Set up your solar panel for optimal solar charging.
• As soon as sucient light falls on the solar module, the horizontal energy display
will begin to ash green. Watching the blinking frequency of the status display will
let you calibrate the best position for your panel. Faster blinking means more energy,
so change the angle of your panel for optimum power.
Your Kalhuohfummi constantly measures the power generated by the Maroshi solar
module, and stores these values internally. The memory contains the last  values of
the solar-energy collector.
When these values are uploaded to the Changers.com community, the COsavings and the
amount of energy produced are displayed graphically for easy reference. This information is
then saved, and added to your user prole.
With the Kalhuohfummi you can charge a large selection of mobile devices – game consoles,
phones, tablets and music players, given they have a USB based charging standard and t
one of the included adapters. Each of the included adapters is suitable for a dierent device.
Before you begin charging, ensure that the device has a suitable charging voltage for a  volt
supply. Too high electric voltage will cause damage.
• Connect the USB charging cable to the   port of the Kalhuohfummi.
• Connect the device with the USB cable to begin charging.
• If in the rare case it is not recognized, please reactivate the output manually by
briey pressing the status button.
• The intelligent charging electronics makes it possible to simultaneously charge
your Kalhuohfummi and your mobile device.
For some devices, such as the apple iPhone and various navigation systems, please use the
cable supplied by the manufacturer. Make sure the connectors match the specications (see
Chapter , Technical Data). The compatibility may not always be completely guaranteed.
5. Four steps to solar sharing

10Care and maintenance
• Remember, the Kalhuohfummi is a battery. Prolonged exposure to direct sunlight
may cause overheating.
• Protect the device against vibrations and shock.
• Keep it free from dust and moisture and ensure it does not overheat.
• Place no ammable, explosive or dangerous objects in the vicinity of the device.
• Never attempt to open the device or repair it yourself.
• Protect the device from rain, humidity and do not place it in liquids.
• Use the device only at a temperature of –°C (– °F) to +  °C (°F).
• If the Charger is not in use, disconnect all cables.
Your Kalhuohfummi stores its energy in rechargeable Lithium-Ion batteries. Their capacity
is measured in Wh (Watt-hours.) Over time these batteries naturally lose their maximum
recharging capacity. Following the guidelines below will ensure a long life of happy, ecient
charging for your batteries.
• The battery should never be exposed to temperatures above +°C (°F).
The optimal ambient temperature is between °C to + °C (°F to °F).
• Any prolonged storage of the battery should be done with a battery charge of about %
(equivalent to two or three LEDs on the display). Failure to do so can result in deep battery
self-discharge, which can damage the battery cells.
• Note the disposal instructions of batteries! (see Chapter , Disposal)
7. Care and maintenance – a little
goes a long way
The Kalhuohfummi is robust, tough and easy to clean. However, like every device with a rechargeable Li-Ion battery, there are
several things you can do to ensure eciency and reliability. Before you contact our customer service team, please ensure you
read the notes in Chapter 8 about the care and operation of your device.
7.1
Safety guidelines
7.2
General guidelines for
Lithium-Ion batteries

11Care and maintenance
• Battery protection system. The Kalhuohfummi comes equipped with an electronic system
which protects the battery against surfeit load. An intelligently designed circuit means
that even if the power is exhausted, the device will not enter a state of deep discharge.
This prevents potential damage to the batteries.
• Solar power battery without charge. If you are unable to load the Kalhuohfummi with
solar power and want to prevent a deep discharge, you can simply charge the battery
with a conventional charger. For this purpose, you can substitute a Universal Charger with
a voltage range from V to V and a current rating of minimum A.
• Recharging an almost discharged battery. Connect the device via the USB charging cable
to your computer or connect it to your panel in the sun. Allow some time to restore you
battery to its original state.
Use a soft cloth only when cleaning the case of the device. Do not use harsh chemicals, strong
detergents or alcohol based products.

Tips for usage and
handling of the
Kalhuohfummi system

12Error handling and customer service
• If the temperature is too high, this will be shown by the status indicator ashing
red/green every two seconds. Remove the device from the source of heat and put
it somewhere cool until the light stops ashing.
• If the temperature of the device is too low this will also be shown by the indicator
ashing red/green every two seconds. In this case, move the device to a warm place
and wait until the status light stops ashing.
• Using an alternative solar module may lead to too high voltage (>V). The status
indicator will alternately ash red and green every two seconds. If this occurs, please
change the solar panel.
• Before contacting our customer service, please check the links between the
Kalhuohfummi and Maroshi devices, to ensure that the problem does not lie there.
