EnglishWhat Is the Wattgate 390i Audio-Grade Power Connector?
Updated
The Wattgate 390i is an audio-grade power connector from Wattgate's "i" series, the same family that includes the 330i and 350i. It is intended for DIY power cables and audio-grade builds where the connector is the interface between the cable and the equipment or wall. The exact gender, current rating, and mating standard are not stated on the Wattgate page provided here, so confirm those details with the dealer or product listing before buying. What the lineup context does tell you is where the 390i sits relative to its siblings: it is one of three "i" connectors Wattgate groups together in its own connector comparison, which is the fastest way to see how it differs from the 330i and 350i.
Where the 390i sits in Wattgate's lineup
Wattgate's site presents its products under headings for products, accessories, connector comparison, contact, metallurgy, international dealers, and a copyright line for RKB Industrial, Inc. The connector comparison page is the relevant reference point: it exists specifically to let buyers compare the "i" series connectors side by side, and the 390i, 330i, and 350i are the three named in the site's own keyword set.
That means the 390i should be treated as one option in a three-way choice rather than a standalone product. The practical question is not "what is the 390i" in isolation but "which of the three fits my build."
How the 390i relates to the 330i and 350i
The Wattgate page provided does not include a spec table, so the differences below are limited to what the lineup structure supports. Use the connector comparison page for the authoritative breakdown.
| Connector | What the lineup context tells you | What to verify before buying |
|---|---|---|
| 330i | One of the three "i" series connectors Wattgate groups for comparison | Gender, mating standard (IEC vs. wall plug), current rating |
| 350i | Same series, positioned as a separate option in the comparison | Same as above |
| 390i | Same series, the third option in the comparison | Same as above |
Because all three share the "i" designation, they belong to the same audio-grade family and are meant to be compared on form factor and application rather than treated as unrelated products. The comparison page is the only place on the site that resolves which is which.
Which connector type the 390i corresponds to
Wattgate's product scope covers audio-grade power connectors and receptacles, and its keyword set includes IEC connectors, plugs, receptacles, and Shuko. The 390i is a connector within that scope, but the page evidence does not state whether it is an IEC connector, a wall plug, or a receptacle.
Do not assume. A connector and a receptacle are different halves of the same connection, and buying the wrong one means the part will not mate with what you already have. Check the product listing or ask the dealer directly which half of the connection the 390i provides.
Typical applications
The 390i fits the same use cases as the rest of the "i" series:
- DIY power cables — building or re-terminating a cable with audio-grade connectors at one or both ends.
- Audio-grade builds — systems where the connector is chosen as part of the power path rather than as a generic part.
- Matching an existing Wattgate setup — replacing or extending a cable that already uses Wattgate connectors.
If your goal is a complete cable, you generally need a connector at each end, and those two ends are often different types (for example, an IEC connector at the equipment end and a plug at the wall end). Confirm which end the 390i serves before ordering a pair.
Checking compatibility before you buy
Work through these steps in order:
- Identify the mating half you need. Look at the equipment inlet or wall outlet you are connecting to. Note whether it is an IEC inlet, a wall receptacle, or something else.
- Open Wattgate's connector comparison page. This is the site's own tool for distinguishing the 330i, 350i, and 390i. Match your required mating half to the connector listed there.
- Confirm the 390i's gender and standard with the seller. The Wattgate page provided does not publish this, so the dealer or the specific product listing is the reliable source.
- Check the receptacle side too. If you are also choosing a Wattgate receptacle, verify that the connector and receptacle are designed to mate. Wattgate's keyword set includes receptacles and Shuko alongside connectors, which means the lineup spans more than one standard — do not assume any connector fits any receptacle.
- Verify current rating against your cable and load. Wattgate's page does not state ratings for the 390i, so get this from the product documentation.
Common pitfalls
- Assuming the 390i is interchangeable with the 330i or 350i. They are grouped for comparison precisely because they differ. Use the comparison page.
- Buying a connector when you need a receptacle. These are opposite halves of the connection.
- Treating the "i" series as one product. The series name indicates family, not identical function.
- Relying on the homepage for specs. The Wattgate page provided contains navigation and a copyright notice, not specifications. Go to the connector comparison page or the individual product listing.
If you can state which two points you are connecting — equipment inlet to cable, cable to wall, and so on — the comparison page will narrow the 330i, 350i, and 390i to the one that matches. That is the decision the lineup is built to support.
