FLO Home X3 vs Emporia Classic
One is built for the coldest driveway on the street. The other is the charger most people should buy. They overlap more than either maker would like.

How this page is funded: we earn a commission if you buy through our Amazon links, at no extra cost to you. It does not change what we recommend, and we say plainly when the honest answer is to buy nothing. Full disclosure.
The FLO is the charger people buy when winter is the design constraint. The Emporia is the charger people buy when they want a safe default. Both are good, and the honest comparison is less about performance than about what your driveway does to hardware in February.

Cold, and what Type 4X adds
A Type 4X rating adds corrosion resistance to the weather protection of Type 4, which is the difference that matters where roads are salted. Add a -40 F published operating range and heat sensors in both the plug and the connector, and the FLO is plainly engineered for a harder life than a garage. Cold-weather chargers.
If your charger lives inside a garage, none of that is doing anything for you, and the Emporia covers the same job for less.
Adjustability from 6 amps
FLO's 6 A floor is unusually low, and it is useful in two specific cases: a shared or undersized circuit where the charger has to be dialed right back, and a household trying to stay under a tight load calculation. Most chargers stop at 16 A. Load calculation.
Which one to buy
- Buy the FLO for an exposed outdoor wall in a cold, salted climate, or if you need to dial the current well below 16 A.
- Buy the Emporia for a garage, a first charger, or a household that wants energy monitoring without paying for it.
- Buy either if the other is unavailable -- on a 14-50 they charge identically at 40 A.
The two chargers
Both ENERGY STAR. One is built for weather, the other for everybody.
1. A first charger, hardwired

Emporia Level 2 EV Charger (Classic)
Emporia · J1772 · 48 A / 11.5 kW · 24 ft cable
The safe default for a first home charger: 48 amps hardwired, a genuinely long cable, a NEMA 4 outdoor-rated case, and no subscription attached to the app.
What is good
- 48 A hardwired is the fastest tier most homes can realistically support
- 24 ft of cable reaches across a two-car garage without a fight
- NEMA Type 4 enclosure is rated for outdoor mounting
- Energy monitoring in the app with no subscription
What is not
- Drops to 40 A if you use the NEMA 14-50 plug rather than hardwiring
- The app is the only way to change the amperage setting
| Maximum output | 48 A / 11.5 kW at 240 V (hardwired) |
|---|---|
| Plug-in output | 40 A with the NEMA 14-50 plug |
| Connector | SAE J1772 |
| Cable | 24 ft |
| Enclosure | NEMA Type 4, indoor or outdoor |
| Certification | UL listed, Energy Star |
| Warranty | 3 years |
Skip this if: Skip it if you want a unit with no app or network connection at all. The Grizzl-E Classic is the simpler machine.

2. 50 A with an app
FLO Home X3
FLO · J1772 · 50 A / 12 kW · 25 ft cable
A 50-amp, Type 4X home charger adjustable from 6 A, sold with a J1772 or NACS connector and a 25 ft cable, hardwired or on a NEMA 14-50 plug. ENERGY STAR listed.
What is good
- Adjustable from 6 A to 50 A
- Type 4X enclosure -- waterproof and corrosion-resistant
- Heat sensors in the plug and the connector
- J1772 or NACS, and hardwire terminals that accept copper or aluminum wiring
What is not
- Three-year warranty on the X3; FLO's five-year term is for the X6 and X8
- The plug-in version's cord is 24 inches, so the receptacle must sit right beside it
- Needs a 70 A circuit to run at the full 50 A
| Maximum output | 50 A / 12 kW at 240 V |
|---|---|
| Adjustable | 6 A to 50 A |
| Connector | J1772 or NACS, chosen at purchase |
| Cable | 25 ft |
| Enclosure | Type 4X, industrial-grade thermoplastic |
| Installation | Hardwired, or NEMA 14-50 plug on a 24-inch cord |
| Heat sensors | In the NEMA plug and the connector |
| App | Schedules, access restriction, charging history |
| ENERGY STAR | Listed |
| Operating temperature | -40 F to 122 F |
| Warranty | 3 years |
Skip this if: Skip it if you want a charger with no app at all, or if you want the full 50 A but your panel cannot carry a 70 A circuit.
