Charging Speed

The Kia EV3 has the higher published DC charging figure at 135 kW, which is roughly 32% higher than the Mercedes-Benz EQA at 102 kW. In practice, that figure only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.

For the published fast-charge window, the Kia EV3 is listed at about 33 minutes, which is 2 minutes quicker than the Mercedes-Benz EQA at 35 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Kia EV3 has a WLTP rated range of approximately 605 km, which is roughly 45 km more than the Mercedes-Benz EQA at approximately 560 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.

Efficiency matters more than battery size for daily driving costs. The Mercedes-Benz EQA consumes 168 Wh/km, compared to 171 Wh/km for the Kia EV3. That means the Mercedes-Benz EQA uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.

A more efficient car does not always mean more range. Battery size plays a role too. The Kia EV3 has approximately 78 kWh of useable battery , while the Mercedes-Benz EQA has approximately 70.5 kWh.

Which One Should You Choose?

If fast charging is your priority, the Kia EV3 has the higher published DC figure (up to 135 kW) and the shorter published charge time at approximately 33 minutes. For long road trips, published stop time matters more than the headline kW number alone.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Mercedes-Benz EQA supports up to 11 kW (22 kW optional), compared to up to 11 kW for the Kia EV3. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.

If you mostly charge at home or at work and care more about daily driving costs, the Mercedes-Benz EQA is the more efficient choice at 168 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Kia EV3 has a WLTP rated range of approximately 605 km, which is roughly 45 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
