The Hellephant Charger is a high-power DC fast charger made by Electrify America
The Hellephant is Electrify America's 350-kilowatt (kW) direct current (DC) fast charger, designed to deliver charge to compatible electric vehicles at speeds significantly faster than standard Level 2 chargers or older DC fast chargers. The name is marketing shorthand — the unit itself is a cabinet-mounted charging station you'll find at public charging networks, not something you install at home.
At 350 kW, a Hellephant can add roughly 200 miles of range to a compatible vehicle in 20 to 30 minutes under ideal conditions. That speed matters most for road trips or when you need a quick top-up between destinations. Not every EV can accept 350 kW of power — the vehicle's onboard charger and battery chemistry determine the actual charging speed — so real-world results vary by make and model.
Electrify America operates these chargers as part of its public network across the United States. You pay per kilowatt-hour or per minute, depending on the network's pricing structure at that location. Membership plans and subscription options are available but not required.
Key Takeaways
- The Hellephant is a 350 kW DC fast charger operated by Electrify America at public charging stations, not a home charger.
- Actual charging speed depends on your vehicle's capability — older EVs and some models max out at 50 to 150 kW even at a Hellephant station.
- You pay per session based on kilowatt-hours delivered or time spent charging, with optional membership plans that may reduce per-session costs.
- Hellephant chargers are most useful for long-distance travel or situations where you need a significant charge in under an hour.
Which vehicles can actually use the full 350 kW
Not all EVs charge at the same speed. A vehicle's maximum charging rate is limited by its onboard charger hardware and battery management system. Newer models from manufacturers like Porsche, Hyundai, Kia, and BMW can accept close to the full 350 kW, while many older or budget-focused EVs max out at 50 to 150 kW.
Your vehicle's manual or the manufacturer's specifications will list its maximum DC fast-charging rate. If your EV charges at 150 kW maximum, plugging it into a Hellephant won't speed things up — you'll charge at 150 kW regardless. The Hellephant's advantage shows up mainly with newer, high-performance models designed to handle that power.
Before a long trip, check your vehicle's charging specs and compare them to the Hellephant's 350 kW capacity. If there's a large gap, you may not benefit from seeking out a Hellephant station over a standard 150 kW DC fast charger.
How Hellephant pricing works at Electrify America stations
Electrify America charges by the kilowatt-hour (kWh) at most Hellephant locations, though some stations use per-minute pricing. Rates vary by region and time of day — peak hours typically cost more than off-peak charging. As of 2024, per-kWh rates generally range from $0.40 to $0.60, but this changes frequently and differs by location.
A full charge on a 75 kWh battery at $0.50 per kWh would cost around $37.50 before any membership discounts. Electrify America offers membership tiers — the standard membership reduces per-kWh rates, while premium memberships add monthly fees but lower the per-session cost further. You can also pay as a guest without membership, though rates are higher.
Check the Electrify America app or website before you charge to see real-time pricing at your chosen station. Prices are posted before you plug in, so you won't face surprise charges.
Hellephant versus other DC fast chargers on the road
The main competitors to Hellephant chargers are Tesla Superchargers, EVgo, Electrify Canada, and other regional networks. Tesla Superchargers operate at up to 250 kW for most models, though newer Superchargers can reach higher speeds. EVgo's fastest chargers max out around 350 kW as well, making them comparable to Hellephant in raw power.
The real difference is network coverage and vehicle compatibility. Tesla Superchargers are only for Tesla vehicles (with some exceptions for newer non-Tesla models in certain regions). Hellephant chargers work with any EV that uses the Combined Charging System (CCS) connector, which covers most non-Tesla vehicles sold in North America. If you drive a Chevy, Ford, Hyundai, Kia, BMW, or Volkswagen EV, Hellephant stations are built for you.
For road-trip planning, use the Electrify America app or Google Maps EV routing to see where Hellephant chargers sit along your route. Availability varies significantly by region — dense coverage exists along major highways in California, the Northeast, and the Midwest, while rural areas may have sparse options.
When a Hellephant charger makes sense for your trip
A Hellephant charger is most useful when you're covering long distances and need to minimize charging time. If you're driving 300+ miles in a day, the speed advantage of 350 kW over a 150 kW charger can save you 15 to 30 minutes per stop. Over multiple stops, that adds up.
For daily commuting or short trips, you won't see much benefit. Home charging overnight is cheaper and more convenient. Local errands rarely require a DC fast charger at all — Level 2 charging at a workplace or shopping center is usually sufficient.
Weather also affects charging speed. Cold temperatures slow charging significantly, even at a Hellephant station. If you're charging in winter or in a cold climate, expect slower speeds than the theoretical maximum.
How to find and use a Hellephant charger
read the Electrify America app or use Google Maps with EV routing enabled. Both show Hellephant locations, real-time availability, and current pricing. The Electrify America app is more detailed — it displays the exact power output available at each charger and lets you reserve a spot in advance at some locations.
When you arrive, pull up to an available charger, open the charging port on your vehicle, and plug in the CCS connector. The app will guide you through payment if you're not a member. Charging begins automatically once payment is confirmed. Most chargers display your session details on a screen, including estimated time to full charge and current cost.
Unplug when your charge reaches your target — you don't need to wait for 100 percent. Charging speed drops significantly after 80 percent, so stopping at 80 percent and moving on is often faster for long trips than waiting for a full charge.
Membership plans and cost comparison
Electrify America offers three membership tiers: no membership (pay-as-you-go), standard membership (monthly fee with per-kWh discounts), and premium membership (higher monthly fee with steeper per-kWh discounts). The break-even point depends on how often you fast-charge.
If you fast-charge more than once or twice a week, a membership plan usually saves money. If you charge occasionally, pay-as-you-go may be cheaper. The Electrify America app shows your membership options and calculates potential savings based on your charging history.
Some vehicle manufacturers, like Hyundai and Kia, include complimentary charging credits or membership discounts for new EV buyers. Check your purchase paperwork or contact your dealer to see if you have any credits available.
Frequently Asked Questions
Can I charge my Tesla at a Hellephant charger?
Not directly. Tesla vehicles use a proprietary connector, not the CCS standard that Hellephant chargers use. However, Tesla has begun opening some Superchargers to non-Tesla vehicles in certain regions, and some newer Tesla models can use an adapter. Check Tesla's website or the Electrify America app to see if your specific vehicle and location support cross-network charging.
What happens if I unplug before my car is fully charged?
You stop charging and pay only for the energy you received. There's no penalty for leaving early. For long trips, stopping at 80 percent and moving on is often faster than waiting for 100 percent, since charging speed drops sharply in the final 20 percent.
Do I need a membership to use Hellephant chargers?
No. You can pay per session without joining any membership plan. Membership reduces your per-kWh rate, so it saves money if you charge frequently. Occasional users often find pay-as-you-go cheaper than paying a monthly membership fee.
How long does a full charge take at a Hellephant station?
It depends on your vehicle's maximum charging speed and battery size. A vehicle that accepts 350 kW with a 75 kWh battery might reach 80 percent in 20 to 30 minutes. Older EVs with lower charging speeds may take 45 minutes to an hour. Check your vehicle's specs and the Electrify America app for estimates at specific stations.
Are Hellephant chargers reliable, or do they break down often?
Electrify America maintains its network, but like any public infrastructure, chargers occasionally go offline for maintenance or repairs. The Electrify America app shows real-time availability, so you can see which chargers are working before you arrive. For road trips, plan a backup charger nearby in case your first choice is unavailable.
