Etronix Male Tamiya To Two 4.0mm Male Connector Adaptor ET0838

Overview

The Etronix Male Tamiya To Two 4.0mm Male Connector Adaptor (ET0838) is an essential accessory for RC enthusiasts who work with mixed connector setups across their fleet of RC cars, chargers and workshop equipment. Whether you're running a collection of RC vehicles with different battery connectors or need to bridge legacy Tamiya-equipped components to modern 4.0mm bullet connectors, this straightforward adaptor offers a practical solution that eliminates the frustration of incompatible plugs. For UK RC hobbyists managing multiple RC car platforms or working across different manufacturers' equipment, this adaptor is an invaluable addition to your RC toolkit.

This adaptor is designed for the RC modeller who has invested in quality batteries, chargers and ESCs across various connector standards. Rather than replacing expensive components or struggling with makeshift solutions, the Etronix adaptor bridges the gap between Tamiya-style male connectors and 4.0mm male bullet connections with a simple, reliable plug-in design. It's the kind of practical accessory that saves time at the track, in the workshop, or on the bench, allowing you to focus on racing and building rather than troubleshooting connectivity issues.

As part of the comprehensive Etronix adaptor cable range, this product sits alongside dozens of other connector conversion solutions, demonstrating Etronix's commitment to helping RC car enthusiasts overcome one of the hobby's most persistent practical challenges. Typical use cases include linking Tamiya-equipped components to hardware that accepts 4.0mm bullet connections, with suggested compatibility across RC batteries, ESCs and chargers where these interfaces are present in your setup.

Key Features

• Converts Tamiya to Dual 4.0mm Connectors — This adaptor bridges a single Tamiya-style male connector to two 4.0mm male bullet connectors, allowing you to connect Tamiya-equipped batteries or components to equipment with 4.0mm female receivers without rewiring or replacing components.
• Straightforward Plug-In Design — No soldering or modification required; simply plug the Tamiya connector into the adaptor's female socket and attach the two 4.0mm male plugs to your destination component, making it ideal for temporary or permanent setup modifications.
• Practical Solution for Mixed-Connector Setups — If you run multiple RC cars from different manufacturers or own a collection that spans older Tamiya-standard equipment and newer 4.0mm bullet systems, this adaptor eliminates the need to maintain separate battery packs, chargers or ESCs for each connector type.
• Reduces Connector Mismatch Issues — One of the biggest pain points in RC hobby organisation is managing incompatible connectors; this adaptor directly addresses that problem by providing immediate compatibility without expensive rewiring.
• Compact and Portable — Lightweight and easy to store, you can keep this adaptor in your pit box, workshop drawer or car bag, ready to deploy whenever you need to bridge a Tamiya-to-4.0mm connection gap.
• Compatible Across RC Applications — Suitable for use with RC batteries, ESCs, chargers and other components featuring Tamiya male and 4.0mm female connectors, making it versatile across cars, benches and workshop setups.

Technical Performance

The Etronix ET0838 adaptor is engineered as a straightforward connector conversion tool built to reliable standards expected from quality RC accessories. The adaptor features a female Tamiya socket designed to receive Tamiya-style male connectors, with internal wiring that splits the connection to deliver two separate 4.0mm male bullet connectors at the output. This dual-output configuration is particularly useful for applications requiring distribution from a single source or for equipment designed to accept two discrete 4.0mm connections in parallel. The construction prioritises reliability and durability, with connectors built to withstand repeated plug-unplug cycles without degradation. The adaptor is designed for use across the full range of typical RC hobby voltages and applications, whether you're connecting batteries, chargers or electronic speed controllers. Like all quality Etronix adaptor cables, this product has been constructed to provide consistent electrical connection with minimal resistance, ensuring your RC equipment receives reliable power delivery. The compact form factor ensures it doesn't interfere with other equipment in your pit box or workshop, and the straightforward engineering means there are no complex features to malfunction — just proven connector compatibility in a single, affordable package.

Frequently Asked Questions

• Will this adaptor work with my Tamiya connector battery and 4.0mm ESC? — Yes, absolutely. If you have a battery with a Tamiya-style male connector and your electronic speed controller has a female 4.0mm bullet socket, this adaptor provides the bridge between them. Simply plug your Tamiya battery connector into the female socket on the adaptor, and attach the two 4.0mm male connectors to the ESC's receiver, allowing power to flow from your battery to your RC car's electronics.
• Can I use this adaptor with multiple RC cars? — Yes, this is one of the main reasons to invest in an adaptor like this. If you have one battery with a Tamiya connector but own several RC cars with 4.0mm receivers, you can use this single adaptor with each car in turn, rather than maintaining duplicate batteries for every connector type in your collection.
• Is this suitable for beginners? — Very much so. This is a passive adaptor requiring no technical knowledge or installation skills; it's a straightforward plug-in solution. Beginners often discover they've accumulated batteries and equipment with different connector standards, and this adaptor solves that problem instantly without any soldering or modification required.
• What is the difference between this and other Etronix adaptor cables? — Etronix manufactures dozens of connector adaptors covering virtually every combination of RC connector standards. The ET0838 specifically converts from Tamiya male to two 4.0mm male outputs. If your requirement is different — for example, converting Deans to 4.0mm, or Tamiya to EC3 — Etronix offers alternative adaptors in their range. Check the full catalogue to find the exact connector combination you need.
• Can I use this adaptor for charging batteries? — Typically, yes, provided your charger has a 4.0mm female socket and your battery has a Tamiya male connector. However, always verify your charger's specifications and ensure the adaptor isn't introducing any unsafe connection points before charging. If you're uncertain, consult your charger manufacturer's guidelines or contact RC Model Shop for advice.
• Is this a permanent solution or temporary workaround? — The adaptor is built to last and can serve as a permanent part of your RC setup if needed. However, many hobbyists view it as a practical tool that allows flexibility — you could solder permanent connectors if you decide a particular battery-to-ESC combination is your long-term standard, but the adaptor gives you the freedom to experiment without rewiring.
