The Bridge That Came First

Before the Brook. Before the Cascade. Before our first charger ever shipped—there was the Bridge.

We launched our adapter series first, not as an accessory, but as a foundation. Because in the EV world, compatibility isn’t a luxury—it’s a requirement. Charging infrastructure is still fragmented, and even in 2025, there’s no single standard that guarantees every driver can plug in anywhere. That’s where adapters come in—they bridge the gap between charging formats, hardware standards, and the realities of how people charge their EVs every day.

Think about it: if you drive a Tesla and the charger at work uses the J1772 standard, you need a Bridge. If you drive a Bolt and someone offers you a Tesla connector, you need a Bridge. If you're at a rental, a hotel, or a public station that doesn’t match your vehicle’s port—you need options. The Bridge Series exists to give you that freedom.

Most EV drivers will encounter mixed charging environments. Public chargers may use J1772, while newer EVs—especially Teslas—rely on the NACS (North American Charging Standard). Without a reliable adapter, you’re either stuck or forced to hunt for a compatible charger. That inconvenience adds friction to the EV experience, and for new owners, it can be a real barrier to adoption. According to the U.S. Department of Energy, charging compatibility remains one of the top infrastructure challenges in EV rollout.

More Than a Throw-In

Adapters are often treated like throw-ins. An afterthought. Something bundled in with a charger or skipped altogether. But at Altreon, we’ve always treated them like essential tools. Because they are.

From day one, the Bridge Series was built to be:

• Rated for 80 amps – future-proofed for high-capacity AC charging and durable enough for any Level 1 or Level 2 EVSE.
• Rugged and compact – built for glove compartments and gear bags, with sealed enclosures that hold up to dust, rain, and daily wear.
• Universal-fit precision – machined to strict tolerances to ensure a snug, secure fit that doesn’t loosen over time or degrade with use.

And perhaps most importantly, they’re affordable. We believe charging access shouldn’t be exclusive or expensive. You shouldn’t need to spend hundreds just to plug in at a friend’s house, a hotel, or your workplace.

What Makes a Good Adapter?

Not all adapters are created equal. A quality adapter must maintain consistent electrical conductivity, avoid excessive heat buildup, and withstand repeated use without performance loss. That’s why our Bridge Series goes through third-party lab testing, in-house batch sampling, and mechanical stress tests to verify reliability over time.

We’ve seen too many low-grade adapters on the market that skip insulation or fail under real-world amperage. The result? Damaged vehicle ports, heat issues, and total charging failure. For a component that sits between your car and the grid, that’s unacceptable.

Why It Came First

The Bridge Series wasn’t an afterthought. It wasn’t a bonus item. It was the first product we built because it solved the first problem we encountered: inconsistent charging access. Long before we engineered our first charger, we saw how often EV drivers were stuck with the wrong plug—and how few solutions existed to fix that.

Adapters might be small, but they represent a big promise: that wherever you go, you’re not stranded. You’ve got options. And that kind of flexibility is what makes EV ownership more approachable and less stressful.

The Bridge is how we started—and how we keep EV charging open, flexible, and real.
