Thailand OEM Power Strips: Turn a Product Photo into a Sample-Ready Specification

If you want to customise a power strip for Thailand, a reference photo and a logo are not enough for an accurate quotation. The photo shows the appearance you like, but it does not tell the manufacturer how to build the plug, socket, rating, cable, protection, USB module, label or packaging.

The file that moves a project into sampling is not a picture marked “same as this.” It is a specification in which each decision can be checked. When I worked from the buyer’s side, I separated the structure, functions, conformity work and packaging instead of letting all four move forward on assumptions.

The five worktables below turn one reference photo into a specification that can be quoted, sampled and accepted.

Sales context → electrical specification → added functions → sample process → labels and packaging

Worktable 1: Who will buy and use this product?

Start with the sales channel and application: retail, project supply, e-commerce, office, household or another use. This decision affects packaging, warnings, frequency of use, cable length and feature selection.

Then confirm the product classification. Thailand’s official TISI information includes TIS 2432-2555 for cord extension sets for household and similar purposes. Whether the final product falls within a mandatory scope, and how an authorised mark may be obtained and used, must be confirmed by the Thai importer or conformity owner. A factory should not make that local decision simply because a product looks like a power strip.

The output from this worktable is not a price. It is three clear lines: target user, sales channel and product classification to be confirmed.

Worktable 2: Draw the plug, socket and electrical specification

Do not write only “Thai three-pin plug.” Provide drawings or clear photographs of the target plug and socket, then confirm:

• Earthing and shutter requirements;
• Voltage, frequency, current and total power;
• Cable type, conductor requirement, length and colour;
• Master switch or individual switches;
• Overload, surge or other protection;
• Outlet quantity, direction and spacing;
• Whether large plugs interfere with adjacent outlets.

The most dangerous words in a purchasing brief are often not technical terms. They are “normal,” “standard” and “same.” None of them can be inspected. Replace them with drawings, ratings, components and test methods so the manufacturer can see which existing construction may be used, what must change and which change may affect the evidence.

Worktable 3: Confirm USB and added functions separately

A power strip with USB-A or USB-C should not be described only as “fast charging.” Confirm the protocol, single-port and multi-port output, total-power allocation, module construction, temperature rise, EMC, labels and report scope.

If the USB module is still open, do not print final output ratings on the packaging. If the AC strip and USB module are supported by different evidence files, those files cannot simply be combined into one whole-product conformity conclusion.

Overload and surge protection also address different risks. Define each device, operating method, reset method, indication and acceptance requirement separately. Avoid uncheckable packaging phrases such as “complete protection.”

Worktable 4: Bring the real process into sample review

Once the enclosure is closed, the buyer cannot see the internal connection. The sample review should therefore keep agreed process evidence, structure photos or a component list and link them to the same sample revision.

The clip below shows a real internal-wire soldering operation at Eagle King. It helps a buyer understand how the connection is assembled, but the video alone cannot determine conductor cross-section, solder quality, material grade or conformity with a standard. The final decision still comes from the approved specification, inspection and applicable reports.

Worktable 5: Freeze labels and packaging last

Packaging should follow the electrical construction and conformity route because the following information depends on the final product:

• Model, ratings and maximum load;
• Outlet quantity, cable length, USB output and protection functions;
• Thai product name, warnings, instructions and responsible-party details;
• Applicable and authorised marks;
• Unit box, master carton, barcode and batch traceability.

The visual design can begin earlier, but do not freeze the key technical statements before the electrical sample. One cable or USB-module change can otherwise make a full batch of printed boxes unusable.

Four RFQ phrases I would cross out in red

“Exactly the same as the picture.” A picture does not define internal construction, ratings or document scope. Use the picture for appearance and add a separate specification.

“Standard Thai plug.” Attach the target plug and socket drawing, and let the importer confirm classification and applicable standards.

“Use the fastest USB.” State the protocol, port allocation, output, temperature and EMC requirements.

“Give the lowest price first; details can come later.” The details create the price. If key specifications are open, a low quotation only means that more assumptions have been made.

How this specification method developed

We have worked in the socket and electrical-accessory industry for 23 years, including 10 years in foreign trade. In overseas OEM projects, the repeated problem is usually not the logo. It is that the construction, technical parameters, documents and packaging are not controlled under the same revision.

Eagle King is based in Cixi, with nearby mould, plastics, copper-part, cable, switch and packaging resources. Our in-house laboratory supports development-stage test planning, sample checks and preparation before third-party approval. These conditions do not replace Thai market-access work, but they help expose conflicts between specifications earlier.

One-page sample-revision freeze

Keep the following items on one controlled page with a revision number:

• Target market, channel and product classification;
• Plug, socket, earthing and shutter drawings;
• Voltage, frequency, current and total power;
• Cable, length, colour and cable-entry method;
• Switch, overload, surge and USB functions;
• Enclosure, colour, logo and dimensions;
• TIS scope confirmation and document owner;
• Thai labels, instructions, packaging and barcode;
• Sample test items, open issues and approvers.

If you already have a Thailand reference product, target plug and socket, ratings and packaging requirements, send them to Eagle King through the WhatsApp button on our website. We will first list the missing specifications, then review the available platform, sample route and evidence gaps. Until the requirement is complete, we will not promise a fixed sampling time or extend an existing report to a new configuration.
