Megawatt Charging blocks
One block. One megawatt. On a trailer.
Mobile DC fast charging blocks with on-board storage, from 350 kW to 1 MW+. Paralleled to fit the site, relocated when the site changes.

MegaWatts power blocks are mobile DC fast charging units of 350 kW, 700 kW and 1 MW+ with on-board battery storage and 2 to 6 dispensers each. They arrive on standard trailers, parallel on a shared DC bus for multi-megawatt sites, charge on CCS1 and NACS today, and accept MCS dispensers under IEC TS 63379.
Who it is for
Sites that need megawatts before the utility can deliver them.
What arrives
A block is a trailer, not a construction project.
Power electronics, storage and dispensers ride on a standard flatbed. It backs onto a level pad, connects on a DC bus, and charges vehicles the day it is commissioned. No trenching, no switchgear inside your building.

How blocks parallel
Add a block, add a megawatt.
1
Shared DC bus
Blocks connect on a common DC bus so any dispenser can draw from any block. One block down does not take a lane down.
2
Dynamic power sharing
The site controller allocates kW across dispensers by vehicle demand and departure time, so 6 trucks on a 1 MW block still leave charged.
3
Recharge strategyConfirm
Batteries recharge from a small grid service, on-site generation or scheduled delivery, sized so the fleet's window is always covered.

FAQ
Block questions, answered.
What is a MegaWatts power block?
A trailer-mounted DC fast charging unit with its own battery storage, power electronics and 2–6 dispensers. It arrives on a standard trailer, sits on a level pad, and charges vehicles the day it is commissioned. Blocks parallel on a shared DC bus to reach multi-megawatt sites.
How does a block get its energy?
Three ways, chosen in the Site Power Plan: a small existing grid service that recharges the battery slowly, a low-emission on-site generator, or scheduled energy delivery. Founder to confirm which energy sources are offered.
Is it really MCS-ready?
The 1 MW+ block is designed to accept a Megawatt Charging System dispenser under IEC TS 63379, published February 2026, for trucks with MCS inlets. The founder sets the delivery date for MCS dispensers.
What connectors ship today?
CCS1 and NACS on every block. Dispensers can be mixed on one block.
How much space does a block need?
A trailer-sized pad per block plus a dispenser lane per port. The calculator on this site estimates footprint; the Site Power Plan measures it.
Who maintains it?
MegaWatts under the SLA: 24/7 monitoring, preventive maintenance, and a replacement target for hardware faults. Customer-operated rentals get remote monitoring and operator training.
