🔌 Connector Types Explained

DC Barrel · XLR · Rosenberger

Not all chargers speak the same language — their connectors do.
Choosing the right one means more than just plug-and-play; it’s about compatibility, safety, and reliability for your eBike or scooter.

Let’s break down the three most common connector types you’ll see in today’s electric mobility world — and how Cyberpika’s Smart GaN eBike Charger adapts to all of them.

⚫ DC Barrel Connectors

The everyday standard.

You’ve seen these before: a simple round plug with a metal tip and hollow sleeve.
DC barrels are used on most 36 V – 54.6 V e-bikes because they’re inexpensive and compact.

Common sizes:

• 5.5 mm × 2.5 mm (used by Aventon, ENGWE, Hiboy, etc.)

• 5.5 mm × 2.1 mm (used by some scooters and smaller e-bikes)

Pros:

• Lightweight and easy to find

• Compact, simple plug-in connection

• Low cost and universal for most mid-range bikes

Cons:

• No lock — can slip out while riding or charging outdoors

• Not waterproof

• Polarity confusion possible (center-positive vs. center-negative)

💡 Tip: Always check the plug size and polarity before connecting a new charger — a mismatch can cause sparks or damage.

🔘 XLR Connectors

The classic three-pin design.

Originally from the audio industry, the XLR connector became popular in larger e-mobility systems because of its secure, locking connection.

Typical use: higher-power 48 V / 60 V batteries and professional scooter or wheelchair chargers.

Pros:

• Locking mechanism prevents accidental unplugging

• Handles higher current (up to 10 A)

• Durable and reliable for daily heavy use

Cons:

• Larger and heavier than DC barrels

• Requires two hands to disconnect

• Not fully waterproof without covers

XLR is ideal if you prioritize secure charging and mechanical stability over portability.

🧲 Rosenberger Magnetic Connectors

Premium meets precision.

Rosenberger connectors — also called Magcode or magnetic snap connectors — are used on high-end e-bikes like Specialized or Stromer.
They attach magnetically, aligning automatically with correct polarity.

Pros:

• Magnetic self-alignment = no fumbling in the dark

• Splash-proof and vibration-resistant

• No risk of bending or breaking pins

• Automatically disconnects if pulled, protecting the port

Cons:

• Higher cost

• Proprietary design — not universal

• Harder to replace or source third-party cables

✨ Smart, safe, and sleek — exactly the future direction of charging design.

🧩 Choosing the Right Connector

🧠 When in doubt: Check your bike’s manual or battery label — it will list the connector type and polarity diagram.

⚡ Why Cyberpika Uses a Universal Approach

The Cyberpika Smart GaN Charger is designed for flexibility.
Its interchangeable cable system allows riders to switch between DC Barrel, XLR, and Rosenberger ends — all while using the same ultra-compact GaN power core.
