Mercedes EQS electric sedan connected to a Level 2 home charger — The Mercedes EQS 450+ charges at up to 9.6 kW on Level 2, adding about 25 miles of range per hour.

Best EV Charger for Mercedes EQS 450+: Top 2 Picks in 2026

Q: Do I need NACS or J1772 for the Mercedes EQS?

The Mercedes EQS uses J1772 for Level 2 AC charging and CCS1 for DC fast charging. It does not use the NACS connector. Choose a charger with a native J1772 plug for the simplest setup. Future Mercedes models may adopt NACS, but current EQS models use J1772. See our NACS vs J1772 guide .

Q: Does the Mercedes EQS qualify for the EV charger tax credit?

The Section 30C tax credit applies to the charging equipment and installation , not the vehicle. You can claim up to 30% of costs (max $1,000 residential) regardless of which EV you own. See our EV charger tax credits guide for eligibility details and how to file.

Q: What size circuit breaker do I need for a Mercedes EQS charger?

The EQS draws a maximum of 40A, so a 50-amp breaker on a dedicated 240V circuit with 8 AWG copper wire is sufficient. If you buy a 48A charger for future-proofing, upgrade to a 60-amp breaker with 6 AWG wire. The ChargePoint Home Flex can be adjusted from 16–50A to match any breaker size. See our dedicated circuit guide .

The Mercedes EQS 450+ is the flagship electric sedan with a massive 108.4 kWh battery and 350 miles of range. Its 9.6 kW onboard charger is slightly lower than some competitors at 40 amps, but that still means a quality Level 2 charger can take it from 10% to 80% overnight — roughly 8 hours.

Because the EQS maxes out at 40A, you do not strictly need a 48A charger. But a 48A unit costs almost the same and gives you headroom for a future EV. Here are our two best picks.

Mercedes EQS Charging Specs You Need to Know

The EQS has a large battery but a moderately-rated onboard charger. Here are the numbers that matter for home charging:

Spec	Value
Onboard Charger	9.6 kW (40A at 240V)
Battery Capacity	108.4 kWh
Connector Type	J1772 (Level 2) / CCS1 (DC Fast)
EPA Range	350 miles
Level 2 Charge Speed (40A)	~25 miles of range per hour
Level 2 Charge Speed (32A)	~20 miles of range per hour
10% to 80% at 40A	~8 hours
10% to 80% at 32A	~10 hours

The EQS's 9.6 kW onboard charger caps out at 40 amps — lower than the 48A found in Tesla and Hyundai/Kia EVs. A 48A or 50A charger will not charge faster; the onboard charger is the bottleneck. However, a higher-amp charger future-proofs you if your next EV has a more powerful onboard charger. See our Level 1 vs Level 2 guide for more on charging speeds.

Our Top Picks

Pick 1: ChargePoint Home Flex — $649 (Premium Pick)

Best for: EQS owners who want a premium charger to match a premium vehicle.

The ChargePoint Home Flex is the ideal companion for the EQS. Its adjustable amperage (16–50A) means you can set it to exactly 40A for optimal EQS charging, or dial up to 50A if you add a higher-powered EV later. The polished app provides energy tracking, cost estimates, TOU scheduling, and push notifications.

For a $100,000+ luxury sedan, the ChargePoint's clean design and premium app experience are a fitting match. The 23-foot cable and NEMA 3R outdoor rating handle any installation scenario. Mercedes me app handles car-side scheduling; ChargePoint adds the energy and cost analytics Mercedes does not provide.

Price: $649
Max amperage: 50A (12 kW)
Connector: J1772
Cable length: 23 ft
WiFi: Yes
Circuit required: 60A dedicated for full speed, or 50A for EQS-only

Pick 2: Emporia Smart Level 2 48A — $429 (Best Value)

Best for: EQS owners who want full-speed charging with energy monitoring at a fair price.

The Emporia Smart 48A delivers more power than the EQS can accept (11.5 kW vs 9.6 kW), which means it fully saturates the onboard charger with headroom to spare. WiFi, energy monitoring, solar integration, and TOU scheduling are all included — features that cost $220 more with the ChargePoint.

The Emporia app is clean and functional, showing real-time power draw, session costs, and charging history. If you do not need the ChargePoint's slightly more polished interface, the Emporia delivers identical EQS charging performance at a significantly lower cost.

Price: $429
Max amperage: 48A (11.5 kW)
Connector: J1772
Cable length: 24 ft
WiFi: Yes
Circuit required: 60A dedicated

Installation Tips for Mercedes EQS Owners

The EQS uses a standard J1772 connector for Level 2 charging. Installation is straightforward, but there are a few considerations specific to this vehicle:

Circuit breaker: The EQS draws only 40A, so a 50-amp breaker is technically sufficient. However, if you buy a 48A charger for future-proofing, install a 60-amp breaker instead. Use 6 AWG copper wire for 48A+ or 8 AWG for 40A.
Charge port location: The EQS charge port is on the rear-right quarter panel. Plan your charger placement so the cable reaches comfortably — the 23–24 foot cables on both picks should cover most garage layouts.
Vehicle length: The EQS is 208 inches long — similar to an S-Class. Ensure your charger cable can reach the rear-right port from wherever the unit is mounted.
Outdoor installation: Both recommended chargers are rated NEMA 3R for outdoor use. The J1772 connector is fully weathersealed during charging, so outdoor charging is safe in all conditions.
Professional installation: Budget $400–$800 for a licensed electrician. Hardwired installation is recommended for consistent 40A+ delivery. See our installation cost guide for a detailed breakdown.

Charging Cost Estimates

Here is what it costs to charge a Mercedes EQS 450+ at home based on the US average electricity rate of $0.16/kWh:

Scenario	Monthly Cost
Average driver (1,000 mi/month)	~$50
Heavy driver (1,500 mi/month)	~$74
Light driver (500 mi/month)	~$25
Full charge (0–100%)	~$17.34

The EQS 450+ consumes approximately 31 kWh per 100 miles (EPA combined). At $0.16/kWh, that is about $4.96 per 100 miles — a fraction of what the gas-powered S-Class costs to fuel. The EQS's 350-mile range means most owners charge once or twice per week. Off-peak TOU rates ($0.08–$0.10/kWh) can bring monthly costs down to $25–$30 for average driving.

Häufig gestellte Fragen

What charger does a Mercedes EQS need?

The Mercedes EQS uses a J1772 connector for Level 2 home charging. Its 9.6 kW onboard charger draws a maximum of 40 amps, so any Level 2 charger rated 40A or higher will deliver maximum speed. We recommend the ChargePoint Home Flex ($649) for premium features or the Emporia Smart 48A ($429) for the best value.

How fast does a Mercedes EQS charge at home?

On a 40A+ Level 2 charger, the EQS 450+ adds approximately 25 miles of range per hour. Charging from 10% to 80% takes about 8 hours — a comfortable overnight charge. On a 32-amp charger, expect around 20 miles per hour and about 10 hours for 10-80%. Use our EV Charging Time Calculator for exact estimates.

Can I use a Level 1 charger with the Mercedes EQS?

Technically yes, but it is extremely impractical. Level 1 (120V) adds only 3–4 miles per hour. The EQS's 108.4 kWh battery would take over 55 hours to charge from 10% to 80% on Level 1. Given the EQS's large battery and luxury positioning, a Level 2 charger is essential for any owner.

Do I need NACS or J1772 for the Mercedes EQS?

The Mercedes EQS uses J1772 for Level 2 AC charging and CCS1 for DC fast charging. It does not use the NACS connector. Choose a charger with a native J1772 plug for the simplest setup. Future Mercedes models may adopt NACS, but current EQS models use J1772. See our NACS vs J1772 guide.

How much does it cost to charge a Mercedes EQS per month?

At the US average of $0.16/kWh, the EQS costs about $50/month for an average driver (1,000 miles/month). The EQS consumes approximately 31 kWh per 100 miles. A full charge costs about $17.34 — a fraction of what premium gas costs for an S-Class. Off-peak TOU rates can reduce monthly costs by 40-50%. Use our EV Charging Cost Calculator.

Can I install a Mercedes EQS charger myself?

If you have a NEMA 14-50 outlet, you can use a plug-in Level 2 charger immediately. For hardwired installation (recommended for reliable 40A+ delivery), hire a licensed electrician. Typical installation cost is $400–$800. The EQS's 40A draw is less demanding than 48A vehicles, so installation requirements are slightly easier.

Does the Mercedes EQS qualify for the EV charger tax credit?

The Section 30C tax credit applies to the charging equipment and installation, not the vehicle. You can claim up to 30% of costs (max $1,000 residential) regardless of which EV you own. See our EV charger tax credits guide for eligibility details and how to file.

What size circuit breaker do I need for a Mercedes EQS charger?

The EQS draws a maximum of 40A, so a 50-amp breaker on a dedicated 240V circuit with 8 AWG copper wire is sufficient. If you buy a 48A charger for future-proofing, upgrade to a 60-amp breaker with 6 AWG wire. The ChargePoint Home Flex can be adjusted from 16–50A to match any breaker size. See our dedicated circuit guide.
