It’s not as powerful as the EF but it’s more compatible as it will work with both there delta and river series and other manufacturers. It’s cheaper and smaller too.

Things that make me worry Bluetti might not be on the ball with this in the advertising on this page BLUETTI Charger 1 | 560W Alternator Charger

1. Picture of a consumer unit MCB used as a 12v breaker - a free floating DIN rail mounted breaker in a high current cable with no other protection is a bit... squirmy



2. Very clear picture of how NOT to wire to any modern vehicle and instead give it endless starter charging issues by wiring the wrong side of the battery shunt - with a side order of unsupported cables that hold up the terminal protection caps

Thanks @jaydisc for your explanations and examples of the results of grounding to the chassis. Very useful.

I'm pretty much starting with a blank canvas. I've got a LHD 2024 VW T6.1 Caravelle (aka Shuttle in the UK) without a leisure battery setup or any portable power. It has a 2,2+1,3 seat arrangement but i've removed the rear 3 seat bench to accommodate the brilliant Van-King bed and steel slider system:

My needs are to keep the whole setup modular as at times I need to remove the bed system to fit the rear bench back and use it to ferry relatives around when they visit...or lose all the rear seats and fill it to the brim with my work equipment. The Van-King bed system can be taken out with one tool in minutes.

I'm now about to get a leisure battery system fitted which, to be honest, is to mainly power the diesel heater that is also going to be fitted. I'm after a very straight forward discreet and tidy battery setup as I don't have great power needs; 5v and 12v outputs as a priority but no real need for AC power. The idea is to fit a 100AH AGM battery under the driver's seat (I have a LHD) with a DC to DC charger and output to a very neat snap-fitting Powerboxx unit under the front passenger seat:

The Powerboxx gives me some 5v and 12v outputs as well as a leisure battery voltage readout. The 220v AC outputs only work when you hook up to shore power but that's not an issue for me. Additionally, when connected to shore the Powerboxx acts as a leisure battery charger if required. I may decide to replicate the Powerboxx setup with something more custom and bespoke but in essence that's what i'm after. I have no need to distribute power to any other point in the van from this source.

What I will add to all this is an EcoFlow Delta 2 and the EF 800W Alternator charger. For one, I need it for when I have my van in work mode to charge batteries and operate power tools both in and out of the van. But also secondly, to power a Dometic CFX3 25 fridge when i'm in leisure mode. I'm not sure the 100AH leisure battery is going to give me the capacity to run the fridge too long during the warmer months here in Spain so that's where the Delta 2 would step in. It will also allow me to reverse charge the leisure battery if required.

The game changer for me is the EcoFlow Alternator Charger. The fast charging potential makes me think that I could nearly forget about lugging solar panels around.

Anyway, this still remains a work in progress but seeing how you've successfully plumbed your EF alternator into your leisure setup has really inspired me!

Wow. That looks and sounds incredible. FWIW, my Delta 2 will power a Dometic 46L 12V fridge for about 3 days 100% to 0% (set to 4°C, with the weather around 28°C during the day), assuming minimal other power use. But yes, much to my surprise and absolute pleasure, the EF Delta + Alt. Charger worked exactly as described and expected. I hope and expect the same for you.

This is how I installed it as a test, to the rear house battery in a Cali Ocean T6.1 2023. Everything seems to work fine, charges with 800W at 13.5 V (after update of EF and EAC) and reverse charges as well. Does it look ok to you how know these things? I guess it will only charge the rear AGM battery? I wonder if Calis battery management system will get confused?
Yes, and the small electronic thing on the -pole (connected with a cable to the +pole)l had the marking in the last picture, just as information.
