Product Overview — In-Line 2.5mm to 3.5mm Adapter for E-Stim Power Boxes

Folks, if you’re mixing and matching electroplay gear, the biggest headache is often the simplest one: different brands use different plug sizes. In-Line 2.5mm to 3.5mm Adapter for E-Stim Power Boxes fixes that by converting a 2.5mm plug to fit a 3.5mm jack—so you can use more of your e-stim accessories with more of your power boxes without replacing your whole setup.

This adapter is designed for electro stimulation gear where compatibility matters. Just remember: if your accessory has multiple plugs that connect to the base unit, you’ll need one adapter for each plug. It’s a small piece that unlocks a lot of flexibility—perfect for expanding your BDSM electroplay kit over time.

Quick answer: an in-line electroplay adapter that converts a 2.5mm plug to work with a 3.5mm jack on e-stim power boxes, helping cross-brand compatibility for electro stimulation / electrical sensation play setups. You’ll need one adapter per plug if your accessory uses multiple plugs.

Specifications, Care & Play — In-Line 2.5mm to 3.5mm Adapter for E-Stim Power Boxes

Measurements & Build

  • Function: converts 2.5mm plug to 3.5mm plug (for connecting into 3.5mm jacks)
  • Use case: electrosex / e-stim power boxes and accessories with different connector sizes
  • Quantity guidance: one adapter required per plug/lead on the accessory
  • Form: in-line adapter

How to Use

Plug your accessory’s 2.5mm connector into the adapter, then plug the adapter into the 3.5mm jack on your power unit (or into the appropriate lead, depending on your setup). If your accessory uses two plugs/leads, use two adapters—one for each plug—so both channels connect correctly. Once everything is securely connected, run your e-stim session as normal, starting at the lowest intensity and increasing gradually.

Care & Safety

  • Use only with compatible e-stim devices and accessories; ensure connections are fully seated before powering on
  • Do not use with damaged leads, frayed cables, or loose connectors
  • Keep electronics and connectors away from water; use only in dry environments
  • Wipe the adapter clean with a dry or lightly damp cloth; do not submerge
  • As with all electro stimulation play: start low, increase gradually, and stop immediately if discomfort occurs

FAQs — In-Line 2.5mm to 3.5mm Adapter for E-Stim Power Boxes

What does this adapter do?

It converts a 2.5mm plug so it can be used with a 3.5mm jack on many e-stim power boxes.

Do I need one or two adapters?

You’ll need one adapter for each plug on the accessory you’re connecting. If your accessory has two plugs/leads, you’ll need two adapters.

Will this let me mix brands?

That’s the goal—many electrosex brands use different plug sizes, and this helps bridge 2.5mm accessories to 3.5mm-jack units.

Is it safe to use?

Use only with intact, undamaged leads and dry conditions, and always start e-stim sessions at the lowest intensity before increasing gradually.

Shipping, Billing & Privacy

Last Updated: August 2026

Your privacy travels with every order

From the moment you check out to the moment your package arrives, every step is designed so that what you buy stays entirely between you and us.

How we appear on your statement

  • Credit / Debit Card: Sp-Tdh-Br
  • PayPal: TDH Retail Ltd

Some banks may display a slightly different or truncated version of these descriptors — this is determined by your financial institution and is outside our control.


What Discreet Shipping Means

Every package we send is prepared with your privacy in mind. If someone sees your order on your doorstep, in your mailroom, or being carried by you, they will have no way to know what’s inside. Even carrier employees handling your package cannot tell from the exterior that it contains intimate products.

  • Plain Packaging: Orders are shipped in standard brown cardboard boxes or plain poly mailers, with no decorative branding.
  • No Branding: No product names, logos, or “TheDildoHub” branding appear on the exterior of your package.
  • Carrier Markings Only: The only external markings are the shipping label and carrier tracking information required for delivery.

Plain cardboard shipping boxes used for discreet packaging

Our Shipping Boxes

We use cartons from Stock Box Company and other established packaging suppliers. The specific packaging used may vary depending on your order’s size, weight, fulfillment location, and availability. Using cartons from different suppliers does not change the discreet nature of your shipment.

All boxes used for shipping are plain, unbranded, and selected to provide appropriate protection during transit. The Stock Box Company cartons pictured above are single-wall boxes supplied from Santa Fe Springs, California. Their printed certification states that they meet the construction requirements of the applicable freight classification.

The certification shown on these cartons lists the following specifications:

  • Bursting-Test Rating: 200 pounds
  • Minimum Combined Facing Weight: 84 pounds per 1,000 square feet
  • Maximum Size Limit: 75 inches
  • Maximum Gross Weight Limit: 65 pounds

These specifications apply to the pictured Stock Box Company cartons. Other boxes may have different manufacturer specifications, but all packaging used for your order is selected for safe transit and maintains the same plain and discreet presentation.

For suitable smaller or lighter shipments, we may use padded poly mailers instead of cardboard boxes. These mailers are also plain and unbranded, with no externally visible product descriptions.


Free Shipping

Free Super Saver Shipping applies automatically to all U.S. orders over $139 — no promo code needed. Every free shipment receives the exact same discreet packaging treatment as any paid tier. Your privacy is never a function of how much you spend.


Order Processing

All orders take 1–2 business days to process before they ship. Orders placed with Express, Priority, or Rush shipping are processed on the next business day. Processing time is separate from transit time, and the delivery estimates for each shipping method begin once your order has been packed and handed to the carrier.

Orders placed on weekends and federal holidays begin processing on the next business day.

  • Processing Time: 1–2 business days for all orders. Express, Priority, and Rush orders are processed the next business day.
  • Tracking Updates: Tracking information may take 24–48 hours to update after your order ships. If it hasn't moved after 48 hours, contact us.

Shipping Rates

All rates are flat per order — not calculated by weight. The same price applies whether you're in Manhattan or rural Alaska. TheDildoHub covers any additional carrier costs; you will never be charged more than the rate shown at checkout.

Transit times begin after your order ships — processing time is not included. Times are estimates; carrier delays, weather, and peak volumes can affect delivery. If significantly delayed, contact us and we'll make it right.

About our domestic carriers

We use USPS, FedEx, UPS, and OnTrac for reliable nationwide shipping. Our fulfillment team automatically selects the best carrier based on your location, speed, and package details. You cannot select a specific carrier, but every carrier delivers in plain, unmarked packaging.

  • FedEx: Ground Economy, Ground, Home Delivery, Express Saver, 2Day, Overnight
  • UPS: SurePost, Ground, 3 Day Select, 2nd Day Air, Next Day Air Saver
  • USPS: Ground Advantage, Priority Mail, Priority Mail Express
  • OnTrac: Ground, Standard, Express

Why is Super Saver slower than Economy?

Super Saver uses the most cost-efficient routing available at the time of fulfillment — typically consolidators or ground services with longer transit windows. Paid tiers use faster, dedicated carrier services. The same discreet packaging applies regardless of speed.

Military address shipping (APO/FPO/DPO)

TheDildoHub is proud to serve American servicemembers. All military shipments go exclusively via USPS as required by military postal regulations. Tracking is always available. Delivery may take additional time due to military postal routing, but every shipment leaves with the same discreet packaging standards.

PO Box delivery

Yes, we ship discreetly to PO Boxes across the nation via USPS. In our experience, PO Box deliveries may take a little longer — typically 1–2 additional days at most.

Delivery instructions

You can add delivery instructions at checkout. Please note that while we pass these on to the carrier, we cannot guarantee they will be followed in all cases. If delivery privacy is a concern, we recommend selecting a tracked speed so you can monitor arrival.

Why we don't guarantee delivery dates

No carrier can truly guarantee delivery in practice. Even express services are subject to delays from weather, carrier volume, and other factors outside our control. Stating estimates rather than guarantees avoids confusion. If your shipment is significantly delayed, we'll work with you to make it right.
