What is the power source of the “Balls” string lights: USB, batteries, or 220 V mains?

For versions with автономous power supply, the use of 3 AA batteries is specified. As a rule, the batteries are not included in the package and must be purchased separately.

Is a USB adapter required and is it included?

In certain configurations, the adapter/USB plug is not supplied. In such cases, any compatible USB power supply unit (for example, from a smartphone) or a USB port of a device with appropriate parameters may be used.

Can the string lights be powered from a power bank, computer, or television?

Yes, if the version supports USB power supply, the string lights may be connected to a power bank or to USB ports of compatible devices.

Are mounting accessories included and how many?

The package contents may vary. Deliveries with self-adhesive mounting accessories (hooks/clips/holders), as well as versions without them, are encountered. Practical data indicate a quantity of 9 mounting accessories in certain configurations.

Is it possible to connect two string lights together (in series)?

There are references to a connector at the end that allows an additional string to be connected. Actual compatibility depends on the version, connector type, and permissible total load; before connection, ensure that your modification provides the corresponding output.

Where are the control buttons located and is there an on/off button?

If your version includes a controller, the buttons are located on the control unit (on the cable or on the battery box). They are typically used for switching the device on/off and for changing operating modes. In versions without a controller, a separate button may be absent.

The string lights are frequently used for soft decorative illumination and as a night light, as the light is generally described as warm and non-irritating. When installing in a children’s room, observe general safety requirements: prevent tension of the wire and mechanical damage.

How should the string lights be mounted on a wall, window, or curtains?

Use appropriate self-adhesive hooks/holders or other mounting accessories suitable for the surface (wallpaper, glass, etc.). Depending on the batch, the mounting accessories may adhere differently; therefore, it is recommended to test fixation on a small area before final installation.

Are the string lights suitable for locations without access to a power outlet?

Yes, if your version provides power from 3 AA batteries, the string lights may be installed in areas without an outlet (for example, on shelves or in zones without convenient power access).

The modes do not switch or are absent — how can the cause be determined?

Check for the presence of a controller and control button on the cable or battery box. If no controller is present, your version likely provides only one mode (steady illumination). If a controller is present, ensure that the button and power supply are functioning properly.

The string lights operate from batteries but do not turn on via USB — what should be done?

This may indicate an issue with the USB cable, connector, or power source. Verify the connection, try another USB power supply unit/port, and ensure that the contact in the connector is not loose. If the problem persists, discontinue use and contact the seller/service center.

What should be done if there are traces of adhesive, chips, or differences in LED color temperature?

It is recommended to check the string lights in operating mode before installation. In case of visible damage (chips, cracks, unstable operation), the product should not be used. Minor cosmetic traces (for example, adhesive residue) are possible but should not affect electrical safety.

Falls may result in cracks and damage to individual elements. It is recommended to unpack carefully and to avoid dropping or sharply bending the string at connection points.

Is it possible to replace the lamps in the string lights?

Practical data mention the possibility of lamp replacement; however, the design depends on the specific modification. If your version does not have service connectors/sockets, the lamps may be non-replaceable.

What type of wire is used: thin or durable?

Assessments vary: references are encountered both to a thin wire and to a sufficiently dense/durable one. The actual thickness and rigidity depend on the version and production batch.
