Fast charging just got sleeker: Delta’s 50kW Wallbox launches in US

Fremont, California-based Delta Electronics just rolled out a sleek new 50kW DC Wallbox charger that’s designed for tight spaces at ACT Expo 2025.

This charger packs a punch in a surprisingly slim, 10-inch-thick, and lightweight (just 225 pounds!) casing that can be wall-mounted or set up on a pedestal. It’s specifically designed for tight spaces like urban parking lots, busy corporate campuses, or crowded fleet operation hubs.

Delta plans to manufacture these 50kW DC Wallbox chargers in Plano, Texas, keeping it local and supporting the rapid EV infrastructure growth across North America.

A 50 kW charger is at the low end of Level 3 fast charging speed, because you don’t always need to charge your car in 25 minutes. It’s the ideal charging speed for shopping, lunch, or seeing a film. Eng Taing, Delta’s senior VP and GM of energy & telecom Infrastructure, says, “Our focus is on seamlessly integrating high efficiency charging into the diverse scenarios of everyday life, including commercial operations, not just maximizing power output.”

We need more of these. They are pretty fast and probably MUCH CHEAPER than 150 KW and 360 KW chargers. And when you use those faster chargers, you quickly end up down at 50 KW anyway.

With a 97% efficiency rate, the Wallbox can juice up two EVs simultaneously using either CCS1 or NACS connectors. Plus, the 23-foot cable makes it easy to accommodate nearly any parking layout, eliminating headaches during installation.

Delta’s vertical integration approach means it handles everything from design to manufacturing. But it doesn’t stop at hardware; the charger also connects to Delta’s IoT platform, offering remote diagnostics, predictive maintenance, and over-the-air updates. That hopefully means fewer disruptions and smoother operations for fleet managers and EV users.
