• It operates at 120 volts with a typical current rating of 15 amps.
• The power output of a NEMA 5-15 outlet ranges from 1.4 to 1.9 kW.

2. Charging Speed for EVs:

• Charging an EV using a NEMA 5-15 outlet is relatively slow.
• Generally provides approximately 3-5 miles of range per hour of charging.
• This charging rate is suitable for overnight charging but might be insufficient for rapid replenishment.

3. Considerations and Limitations:

• Limited power output may not meet the needs of high-capacity EV batteries.
• It's suitable for light usage or as a backup charging option.
• May require adapters or specialized EVSE (Electric Vehicle Supply Equipment) for compatibility.

The NEMA 5-15 outlet, standard in many U.S. households, operates at 120 volts with a typical current rating of 15 amps, providing a power output of 1.4 to 1.9 kW. While its charging speed for EVs is relatively slow, offering about 3-5 miles of range per hour, it serves well for overnight charging needs. However, due to its limited power output, it might not adequately support high-capacity EV batteries. It's best suited for light usage scenarios, serving as a convenient overnight or backup charging option when rapid replenishment isn't a pressing requirement. EVDANCE presents this NEMA 5-15 EV Charger series which is ideal for use at home.

Our two portable chargers are 6-20 plugs by default, but the package comes with a NEMA 6-20 to 5-15, so you can use NEMA 5-15 plugs normally.

II. NEMA 6-20 Charging

1. Description and Power Output:

• NEMA 6-20 outlets operate at 240 volts in the U.S.
• They provide a current rating of 20 amps.
• The power output of a NEMA 6-20 outlet is approximately 3.8 kW.

2. Charging Speed for EVs:

• Charging an EV using a NEMA 6-20 outlet offers faster charging compared to NEMA 5-15.
• Provides around 10-15 miles of range per hour of charging.
• Considered a moderate-speed charging option suitable for daily charging needs.

3. Comparison with NEMA 5-15:

• Significantly faster charging rate compared to NEMA 5-15 due to higher voltage and current.
• Offers approximately double or triple the charging speed of NEMA 5-15.

4. Suitability for Different EV Models:

• Well-suited for mid-range EVs with moderate battery capacities.
• May still be insufficient for high-capacity EVs but can serve as a more efficient alternative to standard household outlets.

The NEMA 6-20 outlet, operating at 240 volts with a 20-amp current rating and a power output of approximately 3.8 kW, presents a notable advancement in charging speed compared to the NEMA 5-15. Offering a range of 10-15 miles per hour of charging, it stands as a moderate-speed option ideal for daily charging needs. Its significantly faster charging rate, nearly double or triple that of the NEMA 5-15, positions it as a more efficient alternative for mid-range EVs with moderate battery capacities. While it may fall short for high-capacity EVs, the NEMA 6-20 outlet serves as an effective choice for faster, more regular charging without the rapid replenishment demands of higher-capacity vehicles.

III. NEMA 14-50 Charging

1. Description and Power Output:

• NEMA 14-50 outlets operate at 240 volts in the U.S.
• They provide a higher current rating of 50 amps.
• The power output of a NEMA 14-50 outlet is around 9.6 kW.

2. Charging Speed for EVs:

• Charging an EV using a NEMA 14-50 outlet offers significantly faster charging compared to NEMA 5-15 and NEMA 6-20.
• Provides approximately 25-30 miles of range per hour of charging, significantly faster than the other outlets mentioned.

3. Comparison with NEMA 5-15 and NEMA 6-20:

• NEMA 14-50 delivers notably higher power compared to both NEMA 5-15 and NEMA 6-20 outlets.
• Offers almost triple the charging speed of NEMA 6-20 and around 5-6 times the speed of NEMA 5-15.
