Do not short connectors
It may cause a fire or electric shock.
Use only 3 V devices
Other working voltage may cause a fire or electric shock.
Do not short the positive terminal and the negative terminal of the Lithium Ion
Capacitor
It may cause a failure by electrolyte leakage, heat, smoke, explosion, or fire as that is charged
before shipment.
Do not let conductive material touch terminals of the Lithium Ion Capacitor or
mounted parts on the board
It may cause an electric shock, burn, or injury. It may cause a failure by electrolyte leakage, heat,
smoke, explosion, or fire.
Do not drop this product. Don’t apply strong impact or vibration to this product
It may cause an electric shock, burn, or injury. It may cause a failure by electrolyte leakage, heat,
smoke, explosion, or fire.
Do not put the circuit board on conductive surface
It may cause an electric shock, burn, or injury. It may cause a failure by electrolyte leakage, heat,
smoke, explosion, or fire by electric short circuit.
CAUTION
Do not use or store this product at high temperatures. Do not let it touch hot objects
Storing in a place where the temperature is out of specification for the storage conditions may
cause a malfunction of this product. In addition, when radiant heat is received from an external
heat source, the surface temperature and internal temperature may rise above the ambient
temperature.
Do not use or store in places where the temperature changes suddenly
Do not use or store in a place where condensation may occur due to sudden temperature
changes. It may cause a failure, fire, or electric shock.
Use and store in a dust-free place
Do not use or store in a dusty or sandy place. It may cause a failure, fire, or electric shock.
Do not touch the port
Do not touch the port during connecting or disconnecting. It may cause an electric shock.
Do not damage the lead wire
A damaged wire may cause a failure, fire, or electric shock.
Do not touch the tip of the lead wire and the terminal
It may cause an electric shock.
Do not touch with bare hands when damaged
In case of this product being damaged, stop using it immediately. Since a glass substrate is used,
and if the product is used as it is, the damaged parts or debris may cause injury or damage to the
human body. Also, since this product contains electrolyte, if it leaks, touching it may cause skin
irritation. Be careful not to touch it with bare hands. In case the electrolyte gets into your eyes or
mouth, immediately rinse with water or lukewarm water and seek medical advice.

Do not place in an unstable place
Dropping it may cause injury.
Do not push with strong force. Do not install with strong force
This may cause damage such as breakage of the glass substrate, resulting in injury.
Charge the LIC by following this guide
Charging the LIC by another method may cause a fire or electric shock.
Do not overload
It is recommended to add a protection circuit if necessary.
Do not repeat rapid charge and discharge. Do not apply ripple current
This may increase internal resistance or reduce the LIC capacity.
Do not touch the port during connecting or disconnecting
It may cause an electric shock.
Do not apply static electricity
It may damage the IC on the circuit board. Handle the circuit board with sufficient measures
against static electricity.

This power module consists of a high efficiency DC/DC converter, a lithium ion
capacitor (LIC), and a dye-sensitized solar cell (DSSC). A constant voltage output
of about 3 V is available even without lighting. You can evaluate whether it is
possible to replace existing batteries with dye-sensitized solar cells without
designing complex circuits.
