Electric Rotating Display Stand: 13.8 cm Size and Power Checks

This electric rotating display stand is listed with a 13.8 cm platform, a 3.5 cm height and a 3 kg load rating. One selected Black or White unit comes with one USB cable, but no batteries. USB 5V input is stated; battery charging, the meaning of the timing settings and stability under load remain unconfirmed.

Those distinctions matter when choosing a small tabletop display for product photographs or presentation. Platform size, power options and package contents answer different questions. A listed setting is also not the same as a verified operating cycle. The checks below separate the available specifications from information still needed for a particular purchase.

What do 13.8 cm and 3.5 cm tell you?

The supplier lists a platform diameter of 13.8 cm, or 138 mm, and a body height of 3.5 cm, or 35 mm. These describe the stand itself, not its shipping box. They are source specifications rather than independent measurements.

Compare them with the space available for your display and the dimensions of the object's base. Diameter alone does not establish fit, balance or retention. It does not provide an approved overhang allowance, either. An object that appears small enough in a photograph is not evidence that its weight distribution suits this platform.

Why is a listed 3 kg load not a stability result?

The stated load rating is 3 kg. This is a supplier and merchant claim, not an independently verified result for every object below that weight.

The reviewed material does not specify load distribution, centre-of-gravity limits, supporting surface or test duration. It therefore cannot establish stability for tall or uneven objects, resistance to slipping or a safe off-centre load. If those conditions matter to your intended display, request the applicable test conditions before relying on the number. No tested safety margin or continuous-use limit is available here.

Which rotation settings are listed, and what is still undefined?

Source labels identify R/L for direction, SR for speed and ASA for angle. Left and right rotation and angle selections of 45, 90, 180 and 360 degrees are listed. These describe the advertised controls, not confirmed looping, reversing, stopping or dwell behaviour. An angled product photograph does not establish a mechanical tilt function.

The parameter image gives 10, 15 and 30 seconds alongside three manual speed settings. It does not define whether these are full-revolution times, angle-movement times or intervals. Do not treat them as seconds per turn or convert them into RPM. Cycle precision, repeatability, remote control and camera synchronization have not been established.

How do USB power and optional batteries differ?

The input is labelled IN-5V / USB 5V. That identifies a stated power input, but not its required current, total power, connector subtype or USB protocol.

The listed battery alternatives are one 18650 or three AAA batteries, with neither supplied. The exact permitted cell specifications and rules for selecting between power sources remain unconfirmed. The format names alone do not settle cell voltage, terminal shape, protection requirements or physical compatibility.

USB input does not prove that the stand charges a battery internally. Rechargeable wording and battery illustrations are not a verified charging specification. No charging time or battery runtime is established by the evidence reviewed for this guide. A complete matching manual is needed to resolve these questions; this section is not an instruction to combine power sources.

What arrives with one selected unit?

The merchant's confirmed package description is one turntable in the selected colour and one USB cable. Batteries and display props are not included. Black and White are separate choices, not a two-unit bundle.

A USB power adapter and a printed manual are not confirmed as included. This contents statement is based on the listing and merchant confirmation, not an independent unboxing. A cable shown in a power illustration is not, by itself, a supplier packing list.

Listed facts and unresolved buying questions

The table keeps a visible label or listed specification separate from a verified performance result. Where information is missing, it remains unresolved rather than being filled in from a similar-looking turntable.

When should you ask for more information before choosing?

Check the current options on the 13.8 cm electric rotating display stand product page. If your purchase depends on internal battery charging, a precisely timed rotation cycle or stability under a particular load, obtain the missing model-specific documentation first.

A full matching manual, exact packing list and documented electrical and load requirements would address these gaps. No complete model-matched manual was obtained in the reviewed evidence. That is not proof that no manual exists or that printed instructions are absent from the package.

Frequently asked questions

Is the 3 kg figure a tested stability guarantee?

No. It is a listed load rating. The reviewed evidence does not establish load distribution, centre-of-gravity limits or test duration, so it does not guarantee stability for an arbitrary object weighing up to 3 kg.

Do 10, 15 and 30 seconds mean one full turn?

That is unconfirmed. The source gives those values without defining the timing basis. They should not be described as full-revolution times or converted into a confirmed rotation speed.

Does the USB port charge an 18650 battery?

Internal battery charging has not been verified. The USB 5V input label and rechargeable-cell imagery do not establish a charging circuit, compatible charging conditions, charge time or runtime.

Are batteries or a USB power adapter included?

Batteries are not included. The merchant confirms one selected turntable and one USB cable. A USB power adapter and printed manual remain unconfirmed; do not assume either is included or definitively excluded.
