Is the EcoFlow Delta Pro The Perfect Portable EV Charging Station?

I've had a lot of my followers ask me for advice on buying a portable EV charger in case of an emergency. There are a lot of portable battery solutions coming to market of late so I'll be checking some of them out to see which units I can recommend for EV charging.

In this video, I take a look at the EcoFlow Delta Pro, a 3.6 kWh portable power bank that's packed with features and is the first of its kind to be able to be recharged from an EV charging station.

This video is powered by Qmerit, North America’s leading provider of installation services for EV charging, home energy storage, and other electrification technologies.

Tom I've been looking at this 120 volt/240 volt portable power station for a couple months now. I'm glad you did a review on it. I have the chargepoint home flex charger that I would plan on charging it with in my garage. well as you shown it doesn't work on the chargepoint home flex. they need to fix this problem before I buy it. Thanks for the review big time you just saved me a lot of grief.

Just FYI, a single Delta Pro can only produce 120v using the 30A NEMA TT-30R outlet. To generate 240v, you need to use two Delta Pros and their double voltage hub.

I think we're missing the main point here - you could connect a couple solar panels to this unit and use it to top your car back up in the event of a power outage. This would enable you to run errands/buy groceries which may only use a couple percent depending on where you live - and then use this to replenish. 1000-2000w worth of panels and 6 hrs of sun plus the full 3 kw battery could make a more of a significant impact.

This Delta Pro power station is so powerful. I am loving it.

[franzconstancio]

Thank you for always having integrity and honesty with your viewers. I was excited to see this as a potential for someone who might purchase this as a alternative power source in the need of a backup for their home. However, having so many issues and additional plugs that would need to be purchased, I don't know if this would be the correct solution for someone who owns an EV. I would probably recommend waiting for a V2G wall unit or a whole house battery by Tesla.

[johnpoldo]

Thanks for the very informative review. This battery back-up unit is more suited to camping than EV emergency charging. Due to battery weight, emergency charging a depleted battery is best done from another EV. We need more EVs with good V2L capability. Good V2L means 240V, not paltry 120. Sadly, Tesla won’t have V2L until CT introduction which keeps getting delayed. New Ford Lightning may offer a great solution.

[ricardowasher]

That is truly one impressive solar generator.

[adamchoi]

I think with the price tag, I’d rather just plug in at a public charger earlier and plan accordingly. I was considering getting a solar setup but the cost per kWh over its possible useful life. Hopefully the technology becomes more mainstream and someday we can setup solar charging for a reasonable price.

[rickytabor]

In all honesty, that Delta Pro is the best solar generator I have ever come across.

[Tony-syed]

I believe another youtuber, Will Prowes, messed up the DC charging module inside his eco flow by adding the grounding plug and charging his Tesla. In his video he says eco flow does not recommend charging an EV since you have to add the grounding plug. His inverter still worked but the issue with bonding fried his DC charging ability so he can not charge it from solar.

[DEEPNNN]

Funnily enough, I was just thinking how I felt your channel was upfront and trustworthy. Kudos

Tom, some of the disadvantages of the Ecoflow can be lessened with a change in equipment type/brand. The recent Pecron E3000 is only 55 pounds, and currently only $1899, no sales tax collected, with a dolly and RV "dog-bone" included, at 3108 watt-hours. (And in tests by the YouTuber Professor Hobo, it appears under-rated, as it delivers 95% of the rated energy capacity as A.C. power.) The reason it is so much lighter is that it is made with high-grade EV batteries, presumably NMC, rather than an iron-based (LFP) chemistry (which reduces lifetime total charge cycles, but reduces the weight dramatically.)
While this unit will not charge an EV quite as quickly in an emergency situation, and is not compatible with being recharged at an EV charger, having it onboard as an "electronic spare-can-of-gas" is quite a bit more practical in terms of price and weight...
(Twelve miles of added range for our Model Y may not seem like much, until you potentially have to walk it...)

[billjohnson]

One thing that is confusing, and I think it got Tom as well. A simple 240V adapter plug will not make this unit supply 240V and charge your EVSE at a level 2 rate. The big socket on the unit is a 30A 120V outlet. For 240V, you need 2 of these monster batteries AND a special 240V cable (named Double Voltage hub) that takes the two 120V units and provides 240V L14-30 twist lock socket. Yikes! Really just a costly level 1 solution, and even more costly for level 2.

[matthewheinrich]

I wonder if the reason the Enel X and Chargepoint EVSE didn't work is because they are 40amp? Maybe the Delta Pro can't negotiate down to 32Amp properly (hopefully fixed in a software update.)

[alexnutcasio]

Tom, the best of the best in BEV reviews and chargers and EVSE!!! Tom cuts through the BS and gives us the real beef.

However, I think most will pass on a 3.7 kWh $3, 600 heavy jump box and power bank. There’s alternatives .

[danmitchell]

Thanks Tom for the review. I purchased the EcoFlow Delta Pro, 400 W foldable solar panels and the EV charging adapter. In addition to the bonding plug you will need to NEMA 14-50 (or other plug) for the Tesla portable charger to charge your Tesla using the 30 amp outlet. I actually have charged my Tesla MY using the NEMA 14-50 plug with the adapter at 24 amps. Charging at a higher rate causes the EcoFlow DP to heat up a bit. And yes, you can only get 10-12 miles/hour of 3+ kWh of charge. I’m retired and don’t drive many miles a day so it’s has been a good way to keep my SOC close to 80%.

[BOK-]

Cool product, and it’s been reviewed by most of your YouTube friends, but glad to see YOUR take!

[randybc]

I think that you could try this when the car is at a lower percentage charge like maybe 42% or 20 % and see if you get more miles?

[Custo]

I must say... One of the better reviewers.

The benefit disclosure was a great move too. This is always on the back of my mind when watching product reviews.

Well done!

[realthoughts]

That was an excellent non biased review in my opinion! The facts were presented, do what you will with the facts! Thanks for bringing this technology to our attention Tom! I would like to know how two of these would compare to a generac for home back up power.
