How their charging profiles differ
The ORA 03 300 (2025) and ORA 03 400 Pro (2025) present different charging characteristics primarily driven by battery capacity and maximum charge limits.
Battery Capacity: The ORA 03 300 (2025) features a 45.4 kWh battery, which is 23% smaller than the ORA 03 400 Pro (2025)'s 59.3 kWh pack. A larger battery offers more driving range but takes proportionally longer to charge at standard charge rates.
At-Home Charging (AC): Both vehicles share the same maximum AC onboard charger rate of 6.6 kW. This means they will draw the same maximum power from home wallboxes.
On-The-Road DC Fast Charging: The ORA 03 300 (2025) accepts up to 67 kW DC, while the ORA 03 400 Pro (2025) supports up to 67 kW DC. They will charge at identical speeds when connected to high-power DC rapid chargers.
ORA Recommendation
For the ORA 03 300 (2025), a standard 7.4 kW home wallbox is ideal for overnight charging. If you travel long distances frequently, look for DC fast chargers capable of supplying at least 67 kW to minimize charging stops.
ORA Recommendation
For the ORA 03 400 Pro (2025), a 7.4 kW home charger is also the perfect fit. Since it supports up to 67 kW DC, you will achieve optimal highway charge times by planning stops at charging stations rated 67 kW or higher.

Max Speed Advisory (6.6 kW)
Your ORA 03 300 (2025) has an onboard AC charger capped at 6.6 kW. A standard 32-amp or 40-amp charger (like the Grizzl-E Classic or Emporia set to 40A) is more than sufficient. While a higher-power 48-amp charger will work safely, it will not charge this vehicle any faster due to the car’s built-in limit, though it does offer excellent future-proofing.
