Does this work with no ground, so that it can charge a vehicle off the V2L NEMA 5-15 socket in the bed of the Rivian?

The Rivian-supplied mobile EVSE doesn’t; a TurboCord Dual doesn’t, but the mobile EVSE supplied with Ford vehicles does. I’m looking for a mobile EVSE that supports this *PLUS* has a TT-30 adapter available. If this supports charging with no ground, I’ll grab one immediately.

I believe we do require the ground on a 5-15, however I will confirm with our tech team and report back.

Is this just a replacement/alternative mobile charger?

This product is an EVSE, not a charger.

 

[Jplus_Mike]

Is this just a replacement/alternative mobile charger?

Yes, the J+ BOOSTER 2 can serve as both a wall charger and a portable charger. We've had quite a few Rivian owners purchase one.

 

[Jplus_Mike]

You are correct. It is an EVSE, not a power source but the common reference to the product is an "ev charger".

 

[UnsungZero_OldTimeAdMan]

Is this just a replacement/alternative mobile charger?

Yes. But structurally tougher and capable of 40A instead of 32A. Plus, availability of more adapters than the two Rivian provides.

Are the safety and durability claims as exaggerated as the performance claims?

• You claim 7x faster all over the place, but then also say that it is only 40A which is 20% slower than Rivian's wall charger that supports 48 amps.
  
  
• You claim that it can fully recharge the battery in 3-4 hours, however at 40A it would take 14 hours. Do the "ideal conditions" that you refer to assume you are recharging a AAA battery? There is no way you are ever going to recharge a Rivian in 3-4 hours using this device.
  
  
• "Weighs only 2.2lbs without cables or adapters" Is the cable removable? It doesn't appear to be removable in the pictures. Why would you advertise the weight of the item with the cable removed when the cable cannot be removed?
  
  
• Also your claim about being resistant to being driven over by vehicles up to 6,600 lbs is not very impressive when you are advertising it for vehicles that weigh 1000 lbs more than that. Might as well just say "don't drive over it - it will break" which is reasonable as most things will break if you drive over it, but why bring it up?

The product actually looks pretty nice, but the unrealistic / excessively hyped claims on your website are ruining it for me.

Wait, so it's not UL certified?

Hey @sub, I totally understand and appreciate your comments. I will address each individually.

1. The 7X faster claim is pretty standard industry claim vs standard Level 1 chargers.

2. The 4 hour claim is referenced for 80% charge on the standard Tesla Model 3, which again is a standard reference point for EV Chargers. There are so many vehicles, we can't possibly list each one so we don't attempt to. We've found that many EV owners, like you, are knowledgeable and aware of this.

3. This is a great question. I don't have an answer for this, as I wasn't part of that decision. I think it references the device weight itself for convenience of the weight it takes to plug into the wall.

4. 6,600lbs is the "rating" but we've had it run over by a WW2 tank and it's still working. The guys at "Now Lets Review" actually ran over the BOOSTER 2 with their Rivian. Check out the video to see how it faired.

Brandon Flasch has a video on it. It does seem to be nice unit. However, being a product that originated from Europe, much of the copy & paste marketing info on/from the site were not written specifically for Rivians.

IMO, the site is too verbose/cluttered. They need to cut down the hype and simplify messaging, instead of expecting prospective customers to scroll and scroll.

Thanks for your feedback on the website. I will pass this on to our team!

It is ETL certified to UL Standards. ETL is the certification body we used to perform the test to comply to the UL defined safety standard.

I hope that clears it up for you.

I can appreciate that the marketing was designed around Tesla being a “standard”, but that’s not exactly the target audience here… and I’m not just being a Rivian-Bro. What about GM, Ford, VW, Mercedes… etc. might be worth an update to language outside the Tesla-Sphere.
