Bluetti's New DC to DC Charger! The Bluetti D40 - What Does It Do? How Does It Work?

[@johnmal5975]

It's really good to see Bluetti, ecoflow and pecron making these units. Great stuff!

[@davidfrancis8899]

This is a specialised product for one model only. I really like your concise and thorough style of reviewing. I also respect your impartiality. Thanks also for offering the consultation services.

[@Jasonoid]

Yeah, it's use case is a bit small since it's only compatible with the AC200L right now. Who knows what future products it will work with. Thanks for checking out the video, David!

[@michaelmartin9022]

Yeah it'd be nice if it was more generic / programmable so it could also be used with the 25amp connector on the AC200Max, or step down 24v to 12 on the AC300 And 500

[@i_LOVE_solar]

Interesting product, Jason. I feel this would be MUCH better if it also charged the AC200L from your alternator (The Pecron 500w and the EcoFlow Alternator charger do a good job at that) Imagine if the 48v port on the AC200L was bidirectional, that would be SWEET! Thanks for breaking down this unit so simply. Excellent job!

[@patrickio8084]

Are the Pecron and or EcoFlow units compatible with this Bluetti?

[@Jasonoid]

No at all. Only The Bluetti AC200L.

[@ashebarley77385]

i do not think the pecron 500w is all that great. only getting like 250 maybe 300w from it and i see a lot of c/o of it being to hot. now the ecoflow alternator is impressive and has app that can be used and really a great product. wish we had that for all of them ... its such a game changer

[@shelley131]

Great review as always. Watching this reminds me that I don't own any products by BlueEtti. It seems to be a constant battle between BluEtti and EcoFlow, like Ford and Chevy. Always enjoy your videos, even if they do not apply to me because I learn something even though I learn more by watching. Thank you for your time and effort.

[@robwinkler4668]

This is a great training video on the D40. I have two AC200L and was curious about the D40 since it was made for the AC200L. This video helped me understand the usefulness of the D40 in charging our motorhome house batteries so I ordered it during Black Friday. Thank You!

[@Jasonoid]

Glad to help out! I'm excited to see your AC200L setup expand!

[@Ursulalb]

It is not logical to have this D 40, as long as the AC 200 MAX directly outputs 12 v with 30 Ah. D 40 seems specially created to give extra money on another device, why wasn't AC 200 L created with the same output port as AC200MAX, ie 12 v 30 Ah?

[@Jasonoid]

Yeah, not a super planned out process.

[@JAJAGO.KELILING.INDONESIA]

i really like your reviews very comprehensive, complete with lot of scenarios subs and thumbs up 🎉🎉

[@CC-gt3ro]

The D40 charges the HOUSE battery of the RV. The new Charger1 560w charges the ac200L from the CHASSIS battery of the RV. I think we can also use a Victron Orion 700w for this task, but the charger1 use the bluetti connector to mc4 solar input so it is simpler.

[@Jasonoid]

Yeah, I'm glad they came out with another solution!

[@dhdoctors]

I suppose this is great for charging van house batteries, but how do we charge the 200L when driving? It's also very cheap to have that pig tail hanging, why not a proper built in connector like the one next to it???

[@Jasonoid]

They didn't plan this to charge the AC200L, I'm not sure why they didn't think of that!

[@AGilbert_81]

Great info Jason. Most likely getting the ac200L before the sale ends & will be considering this D40 for it.

[@iamgrowler]

It looks like I made the right decision when I opted to sell my AC200L. I guess what I envisioned when I plunked down the money was an external device that offered three, maybe four separate 12v outlets that could be used to power multiple high draw fixtures and appliances at once. Fortunately it was on sale when I purchased it, so it wasn't difficult to recoup what I laid out.

[@tarlnobert8033]

Let's say you have the thousand watts of solar panel and you're bringing in that full 1,000 watts in the middle of the day. Will you still only charge the external battery at about 300 w? Or will you be able to put more wattage through the d40 with the pass-through charging? Thank you!

[@goneridingparts]

so bluetti makes this product and the "CHARGER 1". that does charge from the alternator ?

[@Jasonoid]

Yes, I'll be having a video on that new product soon.

[@SpartanOverlandAdventures]

Thanks for the video. Wish it was Bluetti’s response to the EcoFlow and Pecron’s DC to DC chargers.

[@Jasonoid]

This product is a little off in left field. I mean...it could be useful for a few things I showed in the video but I think people want a fast way to charge the AC200L, not a separate battery.

[@SpartanOverlandAdventures]

@@Jasonoid yes! Fast charging I think is the thing most people are after. Really opens up the use of the power center in Overlanding applications!

[@paulr7719]

@@Jasonoid I just want a way to power multiple DC electronics, like a mini fridge, security camera, etc without overloading the unit. I was expecting higher DC output, for what I paid for this thing, and I still don't understand why it's as low as it is.

[@jw3843]

I think this is the first review of this. I know it is the first that I have seen. I know people on facebook are complaining that it limits you to 20 amps if you do not have solar added.

[@Jasonoid]

It has a 20 amp input limit in general. It will pull 20 amps from your alternator and 20 amps from solar (see the second scenario testing section, charging RV house batteries for the exact results).

[@ModernSurvivalSense]

The site says the output should be good up to 400w(you had a moment at 15:00 where your DC supply was outputting 430w to the battery) . 300w is not worth the $200 price tag

[@berniefranklin3586]

Jason I have to admit the admit the only reason for buying the D40 was to have power for my 12V DC s in my items heater, lights etc the D40 output is only maybe only 20 Amps. what do you of think of using a LED power source to convert AC current to 12V DC to supply power to the rest of my camper?

[@brandonandrewsphotography3629]

@Jasonoid Can you run this to a 12V fuse box and house batteries?

[@Jasonoid]

Yes, that will work in the DC output mode.

[@zalllon]

Good overview Jason. Not sure what the mindset is at Bluetti, as the EcoFlow recent release of their DC/DC charger allows flow in both directions. Most people might think the Bluetti D40 was to charge their power station (ie. overlanders), so for us the D40 is useless. The EcoFlow product is pricy (here in Canada), but makes the install pretty easy and great to be able to view from EcoFlow app. Unfortunately for me, I bought the Victron DC/DC 12/24V converter to recharge my Delta 2 Max (via solar port). It is cost effective and also a simple install. But the EcoFlow solution allows the power station to charge the main battery. In any case, I think Bluetti dropped the ball here.

[@Jasonoid]

Yeah, a bit more planning and the device could have been much more!

[@Bolthole_Studios]

Thx Jason, I own both the D40 & 200L. The D40 has some good potential but does come up short (no pass thru, doesn’t charge 200L, 20a limit) There are work arounds but are just that. I don’t like having to manually change from CHARGE Mode to LOAD Mode, so I will most likely leave the D40 in Charge mode and wire my DC Fuse panel to my expansion or house battery. Not clean for single App monitoring/control. Overall, I think Bluetti missed the mark, plus botched the role out.

[@Jasonoid]

Great feedback and I feel exactly the same about it's design. Thanks for commenting.

[@jw3843]

Not bad. I think for the price and since I do not have the 200L I would just go with one of the dc to dc chargers. Not quiet as useful as the ecoflow one that just came out, but you have to have ecoflow delta 2, delta 2 max or the pro I think to make it work with the power station. I know it will charge the power station at 800 watts and I think it will also charge your car battery at 800 watts. Not sure how good that is for the alternator though.

[@Jasonoid]

Great thoughts! I also agree that 800 watts is a bit high for a normal alternator. Luckily the Ecoflow mode is fully adjustable to the charging speed you want 👍

[@atomic8083]

Can you make a video on thw power queens battery plz and where the best place to buy them

[@justtravelthings129]

Hello So the D-40 will charge the 200 L from the alternator so you tried alternator from a van or truck to see if the d-40 is charging from alternator i was watching Ty Fenwick on another video he was saying altenator charging was not working i was just wondering if you have done this thanks

[@Jasonoid]

This does NOT charge the AC200L, this only takes power from the AC200L to charge a 12v battery. It's not like the Ecoflow setup that's bidirectional.

[@justtravelthings129]

@@Jasonoid Thanks so much !!!!

[@max_lewis0469]

Man I can’t get my head around why they would think getting rid of the 12v 30a would be a great idea… maybe if the d40 was by directional but man just want to run my 12v system of this thing.

[@Jasonoid]

Stick with a DIY 12v LFP battery setup. It's simple and batteries are SUPER cheap right now.

[@erubielalanis6658]

The D40 is $200, I suggest people looking to get 12v supply for their whole van/trailer get the AC200Max instead of the L. Using the AC200Max for 12v power only requires a $30 RV cable adapter from Bluetti. I like the AC200L but the missing 12v30amp output was a deal breaker for me.

[@Jasonoid]

The price is very high for what it is. I was hoping it would have also charged the AC200L from the alternator.

[@s999l]

Great review. What's the cable size for the included Anderson connector and what fuse to use when connecting to a fuse box? Thanks

[@solartramp1745]

Bluetti needs to create an alternator charger if they want to take on EcoFlow.

Always found the 48V output weird. Glad I have the max.

[@AskIveSolar]

Still watching but not quite something I'm interested in at the moment. But I'm glad that these companies are giving us options.

So tho basically allows to you integrate the AC200l into an existing 12V system?

[@louisciffer3268]

Hello, thank you for your video ! Do you think is it possible to plug the Bluetti charger on the 12v cigarette lighter ?

[@djrtime1398]

I was torn between the Max and the L. The final choose is the L mainly for its efficiency, lower noise and quick charging. 12v high wattage is a lot lower on the list. I’m not buying the D40. My main application is offgrid rv and offgrid small log cabin. IF and that’s a big IF I need more 12v I can sister the L to two large lead acid batteries for cold weather start up and then one warm switch to the L. The L would then slow recharge and maintain the lead batteries via my 2000 watt UPS. I’m in deep woods so solar is a no-go.

[@teuton6167]

I’m not sure I fully understand this thing but it seems like the 12V 30 amp output on the Bluetti AC 200 Max was a better alternative. Seems like they are charging $200 more for an inferior product. They should just switch back to that.

[@stuartstuart866]

Good morning Jason, what’s the story with the 200 Ah Power Queen with the outlets on top? I don’t see that on Amazon, did you make that?

[@Jasonoid]

I modded the battery so it's more useful. I have a voltmeter, usbc ports and the Anderson ports. It was pretty easy to do since the battery lid is held on with a silicone like glue, they just pry off if you are careful. Here's the video from awhile back: kzbin.info/www/bejne/d5DWmouAobxlpKM

[@jeffreywalker-f1o]

I bought the system shown here (both units). It has been a nightmare trying to get all the necessary wires, etc. for the D40 and the AC200L AND trying to get the system to actually work. The wire to connect the solar panels to the D40 has been out of stock for some time now. Finally ended up making my own red connection, since Amazon had nothing with the Red input connectors already attached to the solar cable. Right now I keep getting an alarm light whenever I start the system up. I have to completely unplug the DC bus bar to get the alarm light to stay off. Don't know if there is a short in the DC wiring or what. This video actually confused me even more. The Bluetti help line isn't very useful, either. They keep asking me to send them a video of what is going on when a simple explanation should suffice. A video doesn't show anything except the red alarm light. I would NEVER go with the Bluetti again.

[@Jasonoid]

The D40 is a very interesting device. I'm sorry my video confused you. I tried to keep it as simple as possible, especially the wiring demonstration. I'd suggest you check wiring polarity. That's the most common issue I see with these errors.

[@matthewobrien1188]

Hi Jason I did a asqme with you before about the D40, but I have another question. If I was to use the D40 to charge a LifePo battery and the AC200L was being charged by 240V shore power, when the AC200L is at 100% will the extra shore power trickle down through the D40 and charge up my LifePo as well??

[@Jasonoid]

From my understanding, the AC200L will charge the LFP battery any time the D40 is connected. So if solar/grid power is connected, both batteries will be charged (AC200L & LFP battery)

[@C8sorbs]

Interesting. I’m using a Renogy 12V 20A DC to DC to charge my AC180 via my alternator but the output voltage is very low. This looks like it could offer a 10x improvement.

[@Jasonoid]

This only charges 12v batteries. It won't improve the charging speed on a power station. The voltage output is also low (13.4v) so you won't see an improvement over what you already have.

I'm also adding a victron dc converter to be able to charge the Bluetti from the alternator. all in the costs are clos to the alternator charger ecoflow just announced.

Since you already have the Pecron smart car charger, you could tie the D40 and smart car charger together at the house battery or vehicle battery to recharge both the house battery and the 200L simultaneously while the vehicle is running.

[@MaRo-u1y]

This makes zero sense to me! I bought the AC240 because of the 30amp 12V DC plug (and the IP rating). I also bought the 210 battery and this thing rocks! The AC240 actually started my 15k btu AC unit in my trailer with no soft start, no problem. I was shocked. The AC200 Max and my Ankers 767 could not start my AC. The only unit I have that could start it is my delta pro. The 200L was a big no for me, would buy a Max, 240 or ankers before I would buy the L. The 48V step down is ridiculous and a waste of a DC plug. Just my 2 cents.

[@Jasonoid]

I completely agree, the AC240 is a much better choice for the high DC loads. That's awesome it starts your AC too! Thanks for sharing your experience!

[@davidparry3058]

yes, I agree, the AC240 is the ideal setup (for me at least), apart from capacity. That threw me. It's a significantly bigger box. Surely they could have fit more cells in. I'm thinking it was partly a marketing decision so as to not cannibalize ongoing sales of earlier units, particularly the 200L, with this D40 unit just hitting the market now. If the AC240 had been 2048Wh or more, it would have been perfect for my needs. I want the ability to be mobile without having to take along an extension unit.

[@MaRo-u1y]

If U were 2 tear down a 240 U would understand why it’s bigger. To get the IP rating there is a lot going on inside, and it’s like a box within a box (probably why others haven’t done an IP rated unit). Paired with the 210 U get almost 3700 WH. I bought both for about 2200 bucks and @ around 61 cents a WH thats a great deal for a unit that has an IP rating and a huge surge rating. The only thing they could have done better is put some wheels on it to make it more portable. But for me I have it installed in my RV so I don’t really move it much (and I have a cart to move it around). But I do agree it seems like a big unit for only 1500 WH. But the 210’s are much smaller so thats a good thang. To be honest I would never buy the 240 on its own, but U start adding batteries and it becomes a legit unit!

[@positronium3525]

Probably be simpler to buy an MPPT and DC to DC converter. A 20A DC to DC goes for less than $100. A 20A MPPT can be bought for less than $90. Both would work for any equipment 12V battery and wouldn't be tied to Bluetti proprietary connector and accessory.

But did you see the Etaker fast charger fleet 1000??? I think it's better then all other option for many generator. He have in solar input 12-48V 20A 500w max, a car alternator input 300W/400W/500W for combine 1000W possible output. Don't find the output voltage of this charger, but the etaker M2000 generator have an input of 20-50V. Look it work with many other generator... Now possible with one device too keep solar and good car charger. And did you see the M2000 unit with semi-solid batteries.

[@berniefranklin3586]

I'm wondering if you need to always put the D40 in load mode and will it stay in load mode because you'll always be using 12V DC to power your 12 V system in your van. One thing you didn't mention is that you can charge the AC200L if you have your alternator connected to the D40 and disconnect it from the 48 V port you can charge the A200L and from what I know around 300 watts. I have a AC200L and think it was a bad move to remove the 30 Amp port like they had on the AC 200 max. it's a proprietary design that leaves anyone who thinks that they can use the AC200 L to handle their 12V DC load is mislead. this is a terrible design and Bluetti is going to be sorry they made it this way. With Ecoflows new DC-DC $600 charger, when they made a universal cable to fit all generators that will be the game changer in my mind with Bi-direcretional charging.

[@Jasonoid]

The D40 puts out 13.4v in load mode so connecting that output to the AC200L input for 'car charging' will only give you around 120 watts. It won't speed up 12v charging on the AC200L. It would be no different than charging with a 12v socket in your car.

This is a silly product. It decreases the 12v output @ 20A max vs the 200max with a native 12v output @ 30A. It won't allow the reverse flow of power back into the Bluetti, so IMO charging a 12v house battery is such a low use case that it is laughable. If the 12v output was the full 40A or even 30A plus it was a high output DC to DC charger that could charge the Bluetti, then it would be useful. But as is, this takes the newer Bluetti's off the shopping list for 3 different projects I have.

[@Jasonoid]

Yep, I agree it's silly. Bluetti has an alternator charger coming out soon I think similar to the Pecron and Ecoflow models.

[@astrobob9432]

D40 was a broken promise by Bluetti. No 30amp output.

[@Jasonoid]

Just 300 watts, a little over 20 amps actual output.

[@paulr7719]

Bluetti states that it has a max of 400w. I take it that was a baldface lie?

[@wt9653]

Pecron did a better job than Bluetti 😮

[@teideterrors]

Nah, its not that good!

[@carl799]

So Bluetti removes the 12 volt 30 amp socket, replaces it with a 48 volt 8 amp socket. Creates a whole new gadget costing you another $199 to have access to a 12 volt 30 amp socket. Wow! No thanks Bluetti.

[@Jasonoid]

Yeah, kinda a bummer. I'd recommend the Pecron E3600LFP. It's a beast and has the 30amp DC output. The Black Friday pricing is amazing on the E3600LFP.

Too bad Bluetti is trash. I had to use my "6 year" warranty as it wasn't charging through solar properly. Took about 10 emails and 3 weeks of back and forth. Eventually gave up and sold it to someone who didn't care about solar input for discount. Never again.

[@Jasonoid]

Thanks for sharing your feedback about their customer support. I wish it was a positive experience for everyone but unfortunately I hear about these cases still every now and then.

What a rip off they should have left it within the unit.

[@Jasonoid]

At least they have the new AC240 with the high amperage output! I feel that feature is super useful so it would have been nice to have that on the AC200L.

[@joebloggs24]

This video did not age well

[@Jasonoid]

Nah, the product was super niche...

[@joebloggs24]

I'm referring to Bluetti's Charger 1 being released recently, not that stone age box that you talk about

[@rebellucy6200]

Bluetti sucks. Mine self drains in a couple days with nothing on. Total waste.

[@Jasonoid]

All power stations self drain if you leave the AC inverter enabled 🤷 I have never tested a power station without any background draw.

[@kellybarfuss7674]

Great video jason!

[@Jasonoid]

@AlternativePower903 I don't choose favorites between different brands of power stations so I don't get offended by someone dissing on a brand, even if it's Bluetti. I do like to hear what's actually happening so I can provide some feedback on what I think is happening or help to make it better. No brand I have ever tested has ever gotten 100% rated capacity. Usually they get around 85% or less on capacity. I have a full spreadsheet and grading system showing those numbers on each model I test.

[@julp7266]

Are you leaving your AC inverter energized?

[@FirebrandChris]

@@julp7266he probably is
