Charging speeds and real-world estimates

Below are some general charging estimates for typical EV battery sizes so you can understand what to expect when you use the Flex-AC at different amperages. Real-world results will vary by vehicle acceptance rate, battery state of charge, temperature, and on-board charger capacity.

Vehicle / Battery size (approx)	Using NEMA 14-50 (240V @ 32 A)	Using lower amp on 240V (e.g., 16 A)	Using NEMA 5-15 (120V)
Small EV / PHEV (8–12 kWh)	6–12 miles range/hr; full charge in ~1–2 hours	3–6 miles range/hr; full in 2–4 hours	1–2 miles range/hr
Compact EV (30–40 kWh)	~20–30 miles range/hr; full in 4–6 hours	~10–15 miles range/hr; full in 8–12 hours	~3–5 miles range/hr
Mid-size EV (60–75 kWh)	~40–55 miles range/hr; full in 7–9 hours	~20–27 miles range/hr; full in 14–18 hours	~5–8 miles range/hr
Large battery EV (90+ kWh)	~60–75 miles range/hr; full in ~10–13 hours	~30–37 miles range/hr; full in 20–25 hours	~8–12 miles range/hr

These numbers are estimates to help you plan charging sessions. If your vehicle accepts a lower maximum current, your real charge rate will be limited by the car’s onboard charger.

Installation and initial setup

Because the Flex-AC is portable and uses adaptors, you don’t need hardwiring or an electrician for basic usage. For Level 2 speeds, you’ll want to plug into a properly installed NEMA 14-50 outlet on a dedicated circuit, and ensure the outlet and breaker are rated for continuous EV charging.

Using NEMA 5-15 vs NEMA 14-50

You’ll plug the NEMA 5-15 adaptor into any standard household outlet for Level 1 charging; this is convenient but slow. For Level 2 charging, swap on the NEMA 14-50 adaptor and plug into that outlet for up to 32 A charging. Always check outlet condition and circuit protection before charging at higher currents.

Safety checks before you plug in

You should make sure the outlet is in good condition, the breaker is sized correctly for continuous load, and the adaptor connections are snug. If you’re unsure about a NEMA 14-50 outlet’s wiring or breaker capacity, consult a qualified electrician to avoid overloading circuits or creating a safety hazard.

App and WiFi features

The Flex-AC includes a built-in WiFi hotspot and a smartphone app that allows remote control and monitoring. You can start and stop charging remotely, check real-time charging data, and schedule sessions to take advantage of off-peak electricity rates.

Remote control, scheduling, and monitoring

You’ll be able to set charging start/stop times, reduce charging amperage remotely, and check energy use if the app exposes that data. The built-in hotspot is useful in locations without a reliable local WiFi network, but initial setup may require connecting the charger to your phone and the local network following the app instructions.

Practical limitations of the smart features

Smart features are convenient, but they can depend on firmware and app stability. If the app or WiFi hotspot is unreliable in your area, you’ll still be able to use the charger manually, but you might lose some convenience features until connectivity is restored.

Safety, certifications and protections

This unit is CSA tested and FCC certified, which indicates it meets recognized safety and electromagnetic compatibility standards. It also includes comprehensive protections against many electrical and environmental hazards.

Built-in protection features

You get over-voltage, under-voltage, overcurrent, overheating, leakage, grounding, lightning, and fire/flame protection built into the charger. These protections help reduce the risk of damage to the charger and your vehicle and offer peace of mind during unattended charging.

NEMA 4 weather rating and outdoor use

The NEMA 4 resistance rating means the unit is suitable for indoor and outdoor use and is designed to resist dust, rain, and snow in typical household and light commercial settings. For severe weather or flood-prone areas, you should still use discretion and follow local guidelines.

Usability and interface

The physical interface is simple — the J1772 handle and status indicators are intuitive, and the mounting accessory helps keep the unit organized. Most users will find the charging workflow straightforward: plug in the adaptor, connect to the car, and monitor through the app or the charger’s lights.

User experience in daily use

You’ll appreciate the light weight when moving the charger and the long cable when parking slightly off from an outlet. The app simplifies scheduling and gives you visibility on energy use, though you’ll want to confirm that firmware updates are current for best reliability.

Compatibility and vehicle support

The Flex-AC’s J1772 connector is the North American standard and will work with all non-Tesla EVs out of the box. You can use a J1772-to-Tesla adapter (sold separately) to charge Tesla vehicles with the same handle.

Charging different EV types

Because the unit allows adjustable amperage down to 6 A, you can safely top up small EVs and PHEVs and also provide faster Level 2 charging for larger battery EVs that accept up to 32 A. Your vehicle’s onboard charger determines the true maximum the car will accept, so check your car’s limits before assuming maximum throughput.
