  Too simple but charges way faster!!!

  First of all, here’s what you will need: You need a 240V circuit with at least a 40A breaker If you want to take full advantage of the 32A Level 2 charging. You also need a NEMA 14-50 outlet. Get a licensed electrician to install one for you if don’t have one. Unfortunately for me, My Plug-in Hybrid BMW 330e is limited to 16A. You may want to double your car’s charging specs. It’s still a lot faster than my the original charger. From zero charge, the charger that came with my car would take 7 hours and 40minutes to fully charge my car. This charger does it in 3 hours and 10 minutes. In just 30 minutes, my car was charged to 20% which is good for 4 miles. It got to 38% within an hour and got to 50% in about 83 minutes. The main unit stayed relatively cool during the whole charging process and so did the wires and outlet. The onscreen display is not fully touchscreen. Only the SET button is. There’s not that many settings to change but put an up and down button at least. The screen displays the device temperature, voltage and current usage, how long it has been charging and how many kWh it has used. It has an LED strip to indicate charging status. That’s it, nothing else on this unit. No physical buttons. It has a feature to set a timer to start charging, up to 12 hours. This does not have bluetooth or wi-fi connectivity and so no app or software either. At least I can get the charging info from my car’s app. 17 foot cable is not long enough, 25 foot would work for me. My car’s charging port is on the left front of the car and my outlet is located on the back wall of my garage. In my case I have to park head in to use it. The outlet plug has wings to make unplugging a bit easier but I wish it the pull handle like some plugs have. It has mounting holes, OOPS not holeS. It has ONE mounting hole in the back for mounting it on the wall. This is a portable unit but I don’t know where I can easily find a 14-50 outlet in my area so this unit will just stay on my wall. I think the outlet plug should come from the bottom of the unit so that the unit can be installed above the outlet and the cable going to the car should be at the top or to the side. There’s also no cable management on the unit. This unit does have Ground Fault protection that you can actually turn on or off and I don’t why you would want to turn it off but it turns out, I needed to turn it off because my house didn’t have good grounding. At least this is what the unit told me when I tried turning it on. Yes, it does work with it turned off but it does make me insecure about it being off. 220V GFCI breakers are not cheap. No oudoor, rainy day charging for me I guess. The unit is built well and the cables seems to be thick and rugged enough to take some beating. The 3 hours that it takes to charge my car compared to 7+ hours is a huge plus for me. There’s a few things that I didn’t like about this unit but they’re not deal breakers for me. Maybe due to the price of this unit, which I think is fair. Oh, maybe that one hole mounting thing might get to me, lol.

  Reliable, Compact and Efficient: Rexing J1772 32A

  • Top 500 Contributor

  I recently received the Rexing J1772 32 Amp EV Charger for review. I was looking for another electric vehicle charger for my house. I already had the 240 volt Nema 14-50 wall outlet I used with my portable charger that came with my vehicle. The charger comes in a great looking zippered carrying case. The small rectangular charger fits neatly in it making it an ideal portable charger. All the charger functions can be set from a single button on the charger. No app is needed or provided. 6 parameters are displayed on the front panel, device temp,charging current,charging voltage,Kwh charger,current settings and charging speed The charger has a large LED bar that lights up with colors Blue during standby or setting up, Green blinking during charging and solid when it is finished and Red if there is a charging fault. This charger automatically started at 32 amps. It has lower settings (16 and 26 amps) if your EV needs lower settings. The settings menu can be accessed by holding the setting button for 3 seconds. The other settings are for timed charging and disabling ground protection . The charger can be mounted on a wall but there is only a single mounting hole at the top. You could perhaps add additional support with a ½ pipe clamp of appropriate diameter on the bottom around the plastic surrounding the charging cable if you are permanently mounting it for more support. I wish Rexing sold a cradle that you could mount that included a hanger for the charging cable so you could easily remove the charger when you wanted to take it with you or leave it mounted. The single hole mount is ok but not ideal for permanent mounting. With that all said it is clear Rexing positions this as a primarily portable charger to be taken out of its storage bag and used when needed. The Rexing J1772 charger is sturdy and has solid construction. Its compact and minimalist design blends well with my garage setup, and the materials used appear to be of high quality. The charging cable is 17 feet long enough to reach my car comfortably, making it convenient to park and charge without any hassle. The 32 Amp charging capacity of this unit ensures that my electric vehicle charges fairly quickly. It's a notable improvement over slower chargers, cutting down my charging time significantly. Using the Rexing J1772 charger is as simple as it can be. It’s plug-and-play by design - you plug it into your power source then your EV's charging port, and it starts charging automatically. The LED indicator lights on the charger provide clear status information, showing when the charger is actively charging (blinking green), finished (solid green), or in standby mode(solid blue). The Rexing J1772 has all the important safety features. The unit does a self check when it is plugged in. It has built-in protection against over-voltage, over-current, over-temperature, and short-circuiting. The safeguards protect your EV and home during the charging process. The Rexing J1772 32 Amp EV Charger is a solid choice for electric vehicle owners seeking a reliable, compact and efficient charging solution. Its sturdy compact build, fast charging speed, ease of use, and safety features make it a great addition to any EV charging setup. The price point of the Rexing J1772 32 Amp EV Charger is reasonable, especially considering its charging capacity and build quality. In my opinion the reliability and efficiency make it a worthwhile investment for EV owners looking for a dependable charging solution.

  Nice charger, easy to use

  • Tech Insider Network Member

  Cheaper in price than the official GM charger. We recently bought a used Chevy bolt and it came with a level 1 charger. The house we live in has a connection to a level 2 charger plug. Right away we knew we needed a level 2 charger as level 1 was not going to work for us. We purchased one directly from GM thinking this was the only option, and it was not cheap. This Rexing level 2 charger works just as well as the GM one and is cheaper and has some better options. I really like that the Rexing charger has a cover over the charging plug. We leave the charger plugged in, but its outside in the weather. The GM charger did not have a cover over the charging plug and that worried me that water would get in and short it out or cause damage to the car if the plug was wet. So having the Rexing with the cover offers me some peace of mind. The Rexing is weather resistant and has held up in some heavy rainstorms. I also like that the Rexing comes with a carrying/storage bag. Using the on-screen display for the Rexing is a little strange and I struggled to make changes (probably user error). However, once I got it setup, I no longer have a need to make adjustments. You can also adjust charging times; I didn't see a need for this since the car is setup to charge only overnight. The cord length is more than sufficient to reach our car from the wall. Overall I really like this charger as it works well and seems have a good build quality. The only advantage the official GM one has is you can swap out the charging connector to a level one or swap in the level 2. This is handy when you are traveling as it gives you access to both charging types while only having one charger. Thats still not enough to sway me to the GM one over the Rexing as this is not a long-distance vehicle and is only used for around the city. I have some other Rexing products and they all seem well made and work great. I wouldn't hesitate buying this brand in the future. So if you need a level two car charger this one is worth checking out based on the quality and price.
