bbfly OBDII Splitter bbfly-B33 — Rotatable Male Port, 16‑Pin Continuity, 4 cm Compact Adapter

bbfly-B33 is a compact two-way OBDII splitter with a rotatable male port that gives you dual OBD2 connections without blocking tight dash spaces.

Use the bbfly-B33 OBD2 J1962 adapter when you need to run two diagnostic devices or one device and a power accessory from a single vehicle OBDII socket. The adapter preserves every one of the standard 16 pins so both downstream connections receive the same signals. Its short 4 cm body and 180-degree adjustable male connector make it simple to fit behind crowded dashboards, while the included DC plug provides an additional power input option up to the specified limit.

How does the rotatable male port help in tight instrument panels?

The male end on the bbfly-B33 turns up to 180 degrees so you can angle it to avoid interfering with nearby trim, steering columns, or other plugs. That flexibility reduces strain on the vehicle's OBDII socket and prevents bulky dongles from sticking out awkwardly.

• 180-degree rotation to fit constrained areas
• Short 4 cm length keeps the assembly compact
• Reduces stress on the vehicle connector for cleaner installations

Will this splitter pass all diagnostic signals to both devices?

Yes — each of the standard 16 contacts is wired through individually so both outputs receive the same OBDII data and power lines. That means scanners, telematics modems, and code readers can operate simultaneously without losing protocol connections.

• Full 16-pin continuity for reliable diagnostics
• Compatible with standard J1962/OBDII vehicle ports
• Designed for simultaneous use of two OBD2 devices

What are the power limits and DC connector use?

The bbfly-B33 includes a DC connector for powering accessories; do not exceed the advised rating to stay within safe operating limits. The adapter is built for vehicle accessory-level power and should be used with devices that respect the stated voltage and current cap.

• DC input rated up to 12V and 5A maximum
• Use with compatible low-voltage OBD accessories and modems
• Helps run external modules without tapping separate wires

How small is this splitter and how will it affect installation?

The adapter has a compact 1.6 inch (4 cm) body so it stays close to the vehicle port and avoids protruding dongles. Its short length and rotatable male pin are purposely engineered to keep the assembly discreet and to allow doors or panels to close without obstruction.

• Overall length approximately 4 cm for minimal profile
• Fits behind panels and in tight footwells more easily than longer extenders
• Ideal for installations where space and clearance matter

Who this is for: technicians, fleet managers, and drivers who need to run two OBD2 devices at once — for diagnostics, telematics, or accessory power — will benefit from the bbfly-B33. It’s suited to garages that swap scanners quickly, to vehicle owners who keep a permanent tracker plus a handheld reader, and to anyone who wants a compact, reliable split without sacrificing full 16-pin connectivity. Avoid using accessories that exceed 12V/5A and verify compatibility with your OBD2 device list before permanent installation.
