ShockFlo Tesla – J1772 Review
I arrived at the hotel, I knew they had EV Chargers, but there was a Tesla using the j1772 charger that I was going to use for my bolt and the Tesla charging station was open. So what did I do? Fortunately, I carry an adapter for these circumstances. It takes the Tesla destination charger plug the North America charging standard according to Tesla and adapts that to j1772 I plugged in I got a charge that night. I was on my way the next day, Im Josh, and this is the channel for people who cannot charge at home or charging weird circumstances, and in this case a weird circumstance is using a Tesla charger on your non tesla today, Ill be looking at one of These adapters, in particular a shock flow 48 amp Tesla to j1772 adapter. This wont work on Tesla superchargers, because that would require DC charging capabilities, and this is only for AC current, so dont try this in a supercharger. It just wont work shock flow, sent me this unit to review, but as youll see opinions, arent necessarily flavored by that arrived in a nice little box, it had nice packaging, it was well protected and a small book instructions that was pretty much it now when it Comes to these adapters, I always like Simplicity, because really all you have to do is take a Tesla charger, plug it into the Tesla end of the unit. Wait a few seconds according to shock flow and then plug into your vehicle.
I found in practice you didnt have to do it in that order or wait. You could actually plug this into your vehicle and then plug the Tesla end in. I dont recommend you do that because if you do the opposite of that youll fry your power pins, so connect this to the cord to the Tesla end then put it in your vehicle when you do connect it to the Tesla M theres a little latching mechanism. Here you need it to be in the position where it says lock to insert the Tesla end. Think of this as the play pause button on your iPhone, it says lock. That means its open. You can put the Tesla end in if it says open. That means its locked and you cant remove the Tesla. However, if you make move it back to lock or open, then you can remove it kind of confusing, on the other end, to prevent you from removing it from the vehicle. You have a little switch and this is the standard switch latch Arrangement that you have on any j1772 plug. You simply push the switch to release the catch on the vehicle, and then you can remove the plug. There is a little switch under the latch that notifies the car that youre going to be disconnecting and itll shut off the power before you remove it that prevents arcing in the pins. When you remove the adapter, you push the button and it switches somewhere.
The one thing I do not like about this adapter is the quality of this switch lack mechanism. So it looks very nice. It has a nice quality shine to it, but when you push it, you dont know where that button is in fact. Sometimes I cant even hear it. You can hear it barely and you have to push it very far before it engages its also very mushy feeling is my best way of describing it. I dont like that because I like to have a nice clean, crisp click when I click this button and I like it to click immediately when I push it. So when you push this one to the socket of the car, the latch slips into a little latch. Clip and when you push this down, you need to have that button engaged before it releases over that lip. If you have to push this too far, theres little danger, you could slip past the lip without notifying the car, youre disengaging and Im, not 100 sure. If thats happening here, because I just cant hear this switch clicking its its really kind of annoying another thing I always look at on these units is the actual female power pins on the j1772 side inside these female pins. Are these rotating finger spring loaded bits that push in against the mail pin thats inserted and those make the connection to the power supply? Now, if that connection, isnt very good, what will happen is this will heat up over time and if it got really really bad, you could potentially melt the unit and mess up your vehicle as well.
There is a different design where the female pin is split into four sections with a metal spring around the outside and that crimps those four pieces in against the mail pin, and I tend to think that is a little bit more secure crimp than this spiralized design. The shockville uses, but either way to test those pins. What I did is I charged a 32 amps, which is the max charging current of my bolt for an hour with the shock flow, and then I hit it with my IR camera to see what the temperature on those pins were. I did the same thing for my Alltel Maxi charger, which has a similar female pin to the shock flow, and I checked the temperature there and you can see that the autel runs three to four degrees Celsius, cooler than the shock flow and considering that this is In the winter time and the ambient temperatures are around freezing thats actually significant in the summer that might be a higher differential. So I dont like how the shock flow handles those connections. It seems like theyre heating up a little bit more than they should be overall. The unit works as intended, you plug it into the vehicle. I can charge it up to 7.7 kilowatts. You hit the button to release, it kills the relay on the Tesla charger and you can release the unit from the vehicle. The sliding switch works, its not perfect, but it works to connect to your Tesla end and so on and so forth.
Theres some nice little knurls on this, its a nice looking design its a little chunky in the hand, but you dont use these things that much so ergonomics isnt a number one concern here. The final thing I did to check out the quality was to open it up, and this has four Phillips screws and a couple Torx screws that you need to take out. The Phillips screws seem to be glued into the unit, which is probably why one of those Twisted off when I opened it up. I was kind of shocked that I could twist it off as easily as I did so once again, not a huge Plus for the shock flow, but once I got into it all the wiring looked good. It is decently weather sealed you can use this in some rain, some moisture I actually tested that. I had it on my car during a decent storm here and I didnt have any issues. Some users have had some issues when you get moisture into the Tesla end. That wasnt my experience in my limited testing. So what do I like about this unit? Well, I like the size, you can throw it in your glove box anywhere else in your car. You need eat it where theres charging emergencies and thats great price is also very good, 100 to 140 dollars. I have links in the description as well as some links that are coupons for my viewers, so you can check those out, but at the same time I dont think the price advantage over the competition is enough to actually recommend this unit.
Youre saving 10 to 30 bucks and just the quality and the way the features are laid out on this thing, such as this confusing switch arent enough for me to recommend now, maybe I would recommend it if youre only using it occasionally for emergencies. I think it should be just fine, but I I still wouldnt recommend this for everyday use, just because Im not sure the quality is up to Snuff. For that still its an interesting adapter. It looks nice and you know if you want to check it out, check it out, but thats. My review of the shock flow 48 amp Tesla CGI 1772 adapter. So, as I said at the beginning, this channel is all about charging for people who cant charge your EVS at home or for when youre out in the road you need to charge somewhere.
