The Rexing - 16A J1772 NEMA 5-15 Level 1 Portable EV Charger is a great on-the-go charger. The charger is constructed nicely and looks like it will stand up to wear and tear. It even comes with a carrying case. What’s so great about this charger compared to many others. A number of things: 1) an LED display on the charging brick 2) The ability to change the power draw (8, 10, 12, or 16A). Why is this important? Depending on the number of other devices plugged into the electrical circuit, a 16A draw maybe too much. It’s nice to be able to adjust the draw on the device directly. Of course the lower the draw, the slower the charging will be. 3) 17 foot cable. In most cases likely long enough, but a 25 foot cable would have been preferred Obviously this portable charger will not replace a level 2 charger or charge your car quickly when you need it. It’s ideal for when traveling and having a half-day or more to plug-in and charge while on the go. Overall, the Rexing 16A J1772 NEMA Level 1 charger is a great portable option. It has replaced the factory BMW level 1 charger included with my vehicle.

Rexing - J1772 portable charger - 16A A nicely thought-out Level 1 (16 Amp) portable charger with a J1772 handle and a NEMA 5-15 connector and a 17 foot cord. Instead of just a dumb Level 1 charger it has brick near the 110 V connector that contains the charging mechanism it also includes a display for charging status and an interface that gives a real time update of charging voltage, charging amps, wattage, time, KWh charged, and settings such as Amperage and how long you want the EV to charge. And according to the manufacturer the charger is equipped with overvoltage, overheat and overcurrent protection. It is solidly built and looks to be extremely durable and weather resistant. This is great for when you need to charge your EV and only have a 110 outlet available to use. And it comes in a nice storage bag. I have swapped my Chevy Level 1 charger with this far superior Level 1 charger and with an added extension cable my family is good to go Level 1 charger when there just isn’t a higher level charger available for our use.

One of the more annoying trends in EVs lately is the decision to stop bundling level 1 chargers with them. While it's true that technically one can get by without one these days, I maintain that charging up your car at home overnight is still by far the most convenient and cost effective way to make sure you stay topped up. This level 1 charger from Rexing is a very good, if somewhat basic, option for your EV that you can get without having to pay a premium for a first party option from the dealer. The charger itself isn't doing anything particularly unusual here. The 16A output is pretty typical for a level one charger, so a charging session is going to require several hours (unlike with a more powerful level 2 charger, which requires a 240v circuit to be added to your home.) The charger is built to be either thrown in your trunk using the convenient carrying bag or semi-permanently mounted on the wall using a few screw posts (not provided.) The cables are sturdy and long enough to work in a typical 2-car garage without issue, while still offering a relatively compact form factor for taking on the go. Some telemetry is available on the charger's screen, but I'll admit I usually forgot to look at it. Again, with level 1 chargers you're usually plugging it in at the end of the day so it can work overnight. I kind of take it as a given that it'll be ready to go after 8 hours. Frankly, it's a little hard to say much more about it. This is not a product that's trying to reinvent the wheel or dazzle you with features. It's a straightforward utilitarian attempt to fill a niche. The basic functionality is all here, which makes it an easy recommendation for anyone looking for a level 1 EV charging solution.

This is the Rexing J1772 16A portable EV charger. The J1772 port is the one that's found on a wide variety of of charging stations and is basically designed for use with L1 to L3 charging. The AC adapter end is for typical 110V US outlets. This particular model can supply up to 16A of charging current (at approximately 110V assuming you're plugged directly at a outlet which is itself not too far from the electrical panel supplying it) or 1.76kW. As 16A is effectively the max normal draw on a circuit with a 20A breaker, which is usually the max on household circuits that are not dedicated for a specific purpose, if you want to get the full draw without tripping your breaker, this may need to be the only device on the circuit. That said, if you're just charging one EV, you may not need to run at 16A for your normal charging. I'll explain. If you're just a single EV household and have a vehicle like the Model 3, your daily commute may only compromise about 10-25% of the battery range, so 28-70 miles round trip. That is an amount this charger can replenish in 8-10 hours which is a normal amount of time for overnight charging. If you're on the lower end, you can charge at a lower current which will generally be gentler on your EV's battery and help prolong it's life and range. If you're regularly driving significantly more than that, this may not be as useful - perhaps on trips where you can charge at an Airbnb or some other location when you've arrived at your destination. Using the charger is pretty straight forward. Plug one end into your wall outlet and the other into your vehicle. Depending on the vehicle, you may need an adapter for J1772. This model has a screen, button, and indicator lights. Most of the time, all you really care about are the lights, specifically the color (red, green, or blue or all three). When first plugged in you'll see all three colors as it detects what's going on then flashing green to indicate charging and solid green when done (vehicle stops drawing current). Seeing red by itself is an error indication of some sort which you'll not need to decode any flashing rate, just read the error from the screen. You'll see blue when you use the button to configure things which is pretty much either seeing current or turning on and off ground connection, and saying a charging time. As this is a, relatively speaking, dumb charger, it outputs the same current when charging and is unable to adjust itself to your circuit. So showing the current man's is needed to deal with other loads on the same circuit as your charger, reducing the rate to something that gives you the desired charge after your normal charging window but perhaps at a lower rate for battery longevity, or if you have demand utility billing, helping keep your max power draw below some threshold. To enter the config menu, you press and hold the button for about 3 seconds. Pressing the button once will cycle through the options on the screen. Pressing and holding for 3s makes a selection. Once you've made a selection, that saves the seeing and exits the config menu. So you need to go through the complete process for everything you want to change. The charge time can be useful depending on your vehicle. Some vehicles can't disconnect the charger electronically. So they need to waste the energy once the battery is charged or had reached the desired set SoC (state of charge). So, to reduce waste, you can program the charger to only charge for a set time then turn off ensuring that you limit waste. This can also be useful for managing time of use electricity billing, you can limit the charging time to when rates are low knowing you won't need to keep a close eye on the time or be around to disconnect the charger. At far as using it goes, the charger for what it claimed. It's reported charging current and my car agreed pretty closely. I could reach the 16A max. Being limited to less than 2kW was a bit problematic for me as I have multiple vehicles which for to how they're used, I need to regularly be able to charge about 50% in four hours. It is convenient for trips and for me, allows an option I can take where I'm not as upset if it's forgotten temporarily it even lost versus my stock mobile charger that's 7.6kW capable on a 240V circuit. In short, it's a pretty decent charger, especially if you don't already have a smarter one, don't need L2 at home, or want a travel option that you'd be less worried about getting damaged or lost.

This is a nicely made unit. This works great as a replacement charger for the cheaply made included chargers that come with many EV brands. It’s also a good “back up” charger if you have one of the super fancy app driven chargers. Build quality is a lot better than the cable that came with my EV, as well as the discount charger that is a top seller on the internet. The cable that connects the j-socket to the charger feels strong and durable. Doesn’t feel like it will degrade quickly. This charger feels like it will last many years and many charging cycles. The cable that came with my EV started to show wear and tear after a few months, forcing me to look for a quality charger elsewhere. I’ve since had a Level 2 plug installed at my home for dedicated car charging, and keep my Level 1 charger for tapping electricity at work or extended shopping trips. It’s definitely worth having as a charger to keep in the car for moments when you find yourself with access to a nearby wall outlet but not a dedicated EV parking spot. Overall, I highly recommend this Level 1 charger. It works fine for charging your car while you are at work for 8 to 10 hours or overnight.

The Rexing - J1772 portable charger - 16A is a portable, Level 1 charging cable primarily design for PHEV's and other vehicles with smaller batteries that can be charged from a regular 120v household circuit. Because it is charging at 120v (not 240v), charging can take around 10 hours (15 kwhr battery), is generally done overnight, and usually does not need any modifications to your home electrical system as long as a 120v receptacle is available. I have a Toyota Rav4 Prime. The Prime is a PHEV with an approxiately usable 15 kwhr battery. The Rexing - J1772 portable charger - 16A is essentially an upgraded replacement for charging cable that Toyota provides with the Prime. It displays information about current, watts, etc. that the OEM cable does not display. In operation, the Rexing performs identical to the Toyota cable. Charging is completed overnight and, when completed, I have about about 51 miles of electrical range. I highly recommend the Rexing cable if you want to charge your PHEV or other smaller battery vehicle from a regular household 120v circuit.

The Rexing - J1772 portable charger is a 16 A charger that is used to charge EV vehicles as well as Tesla EV vehicles. The Rexing charger comes in a well packaged and sturdy box. After opening the packaging box, I noticed it came inside of a nice zip up carrying case. The zip up case allows you to easily store it in the trunk or frunk of my Tesla EV, and take it with me on the go. I did notice a slight quality control issue. The part of the cable that has the screen had several deep scratches. It doesn’t look like it was damaged during shipping because it was wrapped in bubble wrap. It appears it was already scratched before it was shipped. The screen on the digital readout allows you to see the charing input/output. The quality of the screen is somewhat blurry. I won’t complain too much because many portable charging cables do not have this feature. When I charge my Tesla with this cable I was not able to get it to charge when I place the Rexing J1772 adapter on the end of this charging cable. However, when I place my OEM Tesla J1772 adapter on the end of this adapter it works perfectly fine. The cable is long and I had no issue getting it to reach to the charging port on my vehicle when plugged in. The adapter also comes with a removable rubber gasket. This allows you to cover the port from water and dust if you decide to use it outside or store it outside. Overall, it’s a pretty good portable charger for charging my Tesla EV vehicle.

In a pinch, a 16A / 110V charger can give you some extra miles. However, at 1.6Kw per hour, it takes over 24 hours to charge my car. It’s not something I would recommend to anyone for regular use. Rexing’s charger gives a lot of information while it’s working. Several status lights show the state of the outlet, the car, and the charging. It checks to make sure the outlet used for charging is grounded for safety. The output can be set for 10A, 12A, or 16A, depending on your house wiring. While many circuits are 20A, it’s nice to be able to set it lower in cases where the circuit may not support the full speed. The biggest issues are the short cord and heavy converter. The converter box which takes the current from the house and boosts it to 220V is somewhat heavy. It’s The cord to the converter is about 18” long, which is not enough to reach the ground in my garage. This means the heavy converter pulls the plug from the outlet while it’s resting. While there are some outlets which are positioned closer to the ground, there’s no guarantee of what will be found out in the wild. If you’re in need of a portable charger for emergency use, there are better options.

Really love the charger! Easy to use at your own home!
