Ada Pro is getting hot when using?

The heating and cooling functions are used too frequently. Because the heating and cooling modes consume a large amount of power, the battery can release a high amount of energy, resulting in a hot temperature. It is recommended to pause using the device for a while, before trying again.

Ada Pro cleaning and maintenance

Can the silicone material get moldy? How to prevent it?

Under normal circumstances it will not be moldy. It is recommended to wipe it after each cleansing cycle, and then to put it on the charging stand to dry it naturally.

Can I hold the device directly under water?

Just shake the water off or wipe the device and place it on the charging stand. The Ada Pro charging stand is designed to allow the device to dry quickly.

What if the silicone bristles of Ada Pro have degraded to a sticky or bubbly texture?

Discontinue use immediately. Although the silicone of Ada Pro is highly durable, it may degrade under certain conditions of non-normal use. Consult the full manual “Maintenance” section for how to prevent this.

Ada Pro battery and power consumption

The light indicator of Ada Pro does not flash when the charger is connected?

The device is not placed vertically into the wireless charging dock.
The device is not placed correctly, please refer to the “Product Placement” section in the full manual.
The DC charging plug or the power plug are not connected.
The battery is completely exhausted and requires to be charged for a few minutes before it shows the light
indicator again.
When charging for the first time, or when frequently using the heating and cooling function, the device might be in standby mode and temporarily fail to charge.

Can the battery be replaced?

No, the lithium-ion battery is built-in, it can’t be replaced, it can only be charged.

How long does it take to charge each time?

It takes approximately 4-5 hours to charge the battery from an fully exhausted state to a fully charged state.

If the device is not fully charged and used directly, will it damage the battery?

No, it will not. The lithium-ion battery supports cyclic charging, and it does not matter if the device is used in the middle of charging.

How long does the battery last?

When the device is fully charged, in standby mode it can last 180 days; when only cleansing or massage modes are used, it can last for more than 3 months; when cleansing plus massage modes are used, it can last for 1-2 months; when heating or cooling are used, it can last for 3-5 days.

How much power is consumed per use?

The cleansing function consumes about 1% of the power in a single use; the massage function consumes about 1% of the power in a single use; the heating/cooling function consumes about 15%-20% of the power in a single use.

How to judge whether the device is charging?

When the device is charging, the indicator light will display a breathing pulse, which will flash on and off. Be sure to ensure that the body is placed correctly on the charging stand.

How to judge whether the device is fully charged?

When the device is placed on the charging, and the indicator light is steady on, it is fully charged.

I charged the device for less than 5 hours, but the battery is already fully charged?

Because each device is tested in the factory, the device is already partly charged. The 5-hours charging time refers to the time required from a completely empty battery to fully charged.

Ada Pro and specific users

Can the device be used when I have a sensitive skin?

Yes, Ada Pro is suitable for all skin types. However, it is recommended for sensitive skin types to first use the device with the lowest vibration setting and only use it once every 1-2 days. After making sure there are no problems and the skin adapted, you can increase the frequency.

Can pregnant women use the device?

Yes, the Ada Pro Cleansing Instrument is a purely mechanical device. There are no sources of infrared or other, and therefore can be used with confidence.

Heating and cooling modes

How can Ada Pro be used for eye care?

By using the hot temperature, dark circles and eye bags under the eyes can be eliminated; the cold temperature can help to eliminate fatigue and swollen areas.

After initiating the heating or cooling mode, the dual-temp head doesn’t change its temperature?

The battery level is low or exhausted. Due to the high-power consumption of the heating and cooling functions (about 15%-20% for a single use), it must be used when the power is sufficient. It is recommended to charge the device to full capacity before using the heating and cooling modes.
The microprocessor encountered a brief operational error. Please connect the charging cable and place the
device on the wireless charging stand to reset the device to its initial state.
If the outside temperature is extremely hot or cold, it may affect the heating or cooling functions of the device. It is recommended to use the device at a suitable temperature (between 5°C and 28°C).

Why does the dual-temp head feels hot in the heating mode?

The peak temperature of the heating function is 40 degrees. After testing, this temperature is the lowest temperature that can effectively remove dark circles. Because the skin of the eye is sensitive, the sudden change to a temperature of 40 degrees will cause a stress reaction. It is recommended that the dual-temp head is placed on the skin immediately after the heating mode is turned on, and the temperature change will be more gradual.
