Grizzl-E Duo Level 2 Plug in EV Charger, up to 40 Amp, Two 24 feet Premium Cables (14-50 Plug)

This is the easiest, least cost out of the box reliable solution to the problem of how to charge 2 EVs with one 50 amp 1540 240 volt outlet. This is a very simple, non networked charger, so no apps to set up, no wireless connections to make, no remote monitoring by third parties of how and when and how much you charge. Its super simple to install, plug into your outlet, attach the mounting bracket to the wall, hang the unit on the mounting bracket, attach to the wall the charge plug holsters, and you are done. The unit appears well made, has some weight to it like you would expect a quality product to have. When charging a single EV, it delivers 9 kw, either plug, an improvement over the 32 amp 7.5 kw rate our old charger delivered. When charging a second Ev, both EVs will get 4.5 kw. We found this is enough to charge both even if both are low, overnight. When either of the two EVs finishes charging, the rate on the remaining Ev being charged goes to 7.5 kw -- this per the manual is by design. (note: you need to download the manual, nothing in the box). There is a blinking light on the front of the unit to provide status of the charging, and this changes color and rate of flashing to signal what the unit is doing. You will need the manual to decode the colors and flash rates. This takes some time and effort if you are so inclined. I dont bother with it, the only codes that bear paying attention to are fault codes which per the manual flash red. We have had the unit for a couple of weeks now and have had no faults and the unit has performed exactly the way we hoped.

Pros:1. Does the job it's supposed to with no fuss2. Easy installation (although a little more difficult to direct wire than its singular counterpart)3. No delicate "smarts" to break the charger by going stupid.4. Well-constructed sealed metal case.5. Plug holsters are separate from the charger, so you can put them anywhere, and you aren't beating on the unit when you hang up the plug.Con:1. As some have mentioned, the charger will put 32A at most to one vehicle when two are plugged in and one is not charging. This hasn't actually had any impact on me at all; here's the math of why it isn't a problem for me:I have two EVs, a Nissan Leaf (24kWh battery) and a Tesla Model 3 long range (75 kWh).The Leaf's recommended discharge/charge range is 20-100% due to their battery chemistry being more tolerant to full charging (according to Nissan), so a max normal charge on it is 80% of the battery, or 19.2 kWh.The Model 3's recommended range is 20-80%, or 20-85%, depending on who you talk to. I do 20-80%, which makes the max normal charge 60% of the battery, or 45kWh.A 240volt charger at 40A puts out 9.6 kW (9.6 kWh/h), and at 32A it puts out 7.68kW, so:Normal charge of the Leaf is 2 hours at 40A and 2.5 hours at 32A.For the Model 3's, 40A takes 4.69 hours and 32A takes 5.86 hours.Admittedly, I have not accounted for the small amount of loss that takes place between charger and vehicle, but in electrical systems, higher currents experience higher percentage loss, so it would most likely narrow this gap even further.So far, having the Leaf for over 4 years, and the Model 3 for 2, I have not run into (nor could I imagine) a situation in my normal day-to-day where the 20% reduction in charging time going from 32A to 40A would matter, as Level 2 home charging isn't meant to be a quick "gas-n-go" type of experience; it saves a ton of money (roughly $200/month for me), not time. If I did experience that unicorn of a situation, unplugging the other vehicle (which has already finished charging) to get the full 40A seems trivial and unimpactful to the usability of the charger. Maybe I would feel differently if I had a vehicle that took 10 or more hours to do a 20-80 charge at 40A, where sitting overnight might not get a full charge at 32A, but the battery pack would have to be 160+kWh for that, which is pretty huge. I'd be looking for a charger with higher amperage than 40A at that point. Went ahead and looked it up as I was curious, and the Hummer EV has a 212kWh battery pack, but less range than the 75kWh Model 3; no judgement if that's your thing, but I'll stick with the 3x more efficient car, and you might want to see if there's a charger that does 100A.On to the other thing worth mentioning; direct wire installation is trickier with the dual than it was for the single. The important stuff did not change; it still accepts the 3/4" flex conduit (Ultratite non-metallic) in place of the pigtail without any extra parts, and the wiring itself still uses the screw terminals. The difference is that the dual has two full-size copies of the single's circuit board, connected with some signal wires that are probably there to balance the load, and since the wiring input runs to the back board, you have to disconnect and remove the front one to wire it up. I'm sure we're all licensed electricians here (right???), just make note/take pictures of what's connected to what as you go and you'll be fine.Anyway, this charger is great so far, but if something changes my opinion, I'll update!

Very excited about this item as it is half the price of the other dual charger. Installed perfectly and charged my vehicle but constantly heard a clicking sound as it kept trying to turn on the other charger (second car not plugged in). Realized that it was probably alternating between the two, the car kept initializing every 30 seconds. Contacted tech support, told me it shouldn't do that and that they would "get back to me." An entire day passed and no word. Why wouldn't you call me to try to troubleshoot? As someone who was an early adopter of EVs, I have a lot of experience and my Chargepoint has never had these issues. Its over 6 years old and going strong. This isn't working on day 1 and no instant tech support available. Also the LED lights are silly. Without a key taped to the unit, too confusing. This will probably go back soon.Update: Tech support got back to me and said this was the design of this model. It will continue to initialize the car constantly when the car is topped off. This does not allow my vehicle to go to sleep and I believe this will eventually damage my car. They recommended I return if I do not want my car constantly initializing.
