On the headline numbers these two are twins: 50 A hardwired, 25 ft of cable, three years of warranty. The decision is made by the outlet you already have, the car you drive, and how exposed the wall is.

- Enclosure. FLO describes its Type 4X case as waterproof and corrosion-resistant and rates it to -40 F; Autel rates its NEMA Type 4 case for rain, snow, hail and sleet. Outdoor chargers.
- If the Wi-Fi drops. The Autel also connects over Bluetooth; FLO lists 2.4 GHz Wi-Fi, with cellular still in development.

Full specifications and the case against each.
1. 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.

2. Long reach outdoors
Autel MaxiCharger AC Home
Autel Energy · J1772 · 50 A / 12 kW · 25 ft cable
The 25 ft cable is the longest in this group, and the NEMA 4 case plus a cold-flexible cord make it the easiest unit to live with on an exposed outside wall.
What is good
- 25 ft cable, the longest of the wall units here
- Sold in NEMA 14-50, NEMA 6-50 and hardwired versions
- NEMA Type 4 enclosure rated for rain, snow, hail and sleet
- Wi-Fi and Bluetooth, so it still works if the Wi-Fi drops
What is not
- The 50 A version is hardwired only
- The app has more features than a first-time owner needs
| Maximum output | 50 A / 12 kW hardwired; 40 A / 9.6 kW plug-in |
|---|---|
| Connector | SAE J1772 |
| Cable | 25 ft |
| Enclosure | NEMA Type 4 |
| Certification | Tested to UL standards by CSA |
| Warranty | 3 years |
Skip this if: Skip it if your parking spot is right next to the panel. You are paying for cable you will coil up and never use.

The verdict
Autel MaxiCharger if your outlet is a 6-50 or you want Bluetooth as a fallback. FLO Home X3 for a NACS connector or the coldest, most exposed walls.
