  • Works great for charging an Ecoflow battery backup using cars alternator
Works great. A couple tips: The cell phone App will not work on the road if you used house wifi to connect, But you can delete this unit from the App and reinstall easily and it will then use Bluetooth to enable using App on phone again. It keeps working in previous mode even when app is unavailable, My alternator is rated 135 amps but could only get the 70 amps of max charge rate intermittently due to my "Smart" alternator. Many modern alternators reduce voltage output during acceleration etc to increase efficiency/ mileage and hence this unit can't get full amps all the time. My charge time was significantly longer due to this (maybe 50% longer? ). The most critical thing to keep in mind is the unit cuts out if it detects voltage too low like when car is off.. (But this will also happen with a "smart" alternator that reduces voltage under certain conditions..) You can reduce the cut out voltage easily through the well laid out phone App, BUT you now have to make sure you turn off the unit before shutting off the car or it Will start draining your car battery because it now "thinks" that the car is still running if you lower the cut-out voltage.. Unit restarts from sleep if you power on the Ecoflow battery back up sometimes too so make sure the green led on the side of the unit is off if you're still connected to the car (if you lowered the cut-out voltage). You can see if you have a "Smart" alternator by plugging one of those little LED voltage readers into your cigarette lighter and keep an eye on voltage swings while driving (voltage starts at ~14volts after starting vehicle but will then vary between 12 and 13 volts as you drive if it's a "Smart" alternator) ... show more

  • A must for if you use for EcoFlow for long road trips.
This is a game changer if you use your EcoFlow Power Station for long road trips. I use mine in my truck camper where it charges my EF Delta 2 w/ Extra Battery that in turn powers a 12V fridge/freezer. While driving my power station is always fully charged as the 800W charger is more than my fridge (and any other accessories I have plugged in) are drawing. This allows my start camp with a full battery to last throughout the night before I hit the road again. Great product. ... show more

  • Beast of a charger; perfect for topping off EcoFlow batteries for camping
This is the long-awaited solution to charging up EcoFlow power stations like the Delta 2 series or Delta Pro (with a Smart Generator Adaptor) in your truck, SUV, or car. It's DC-to-DC so no more AC inverter losses, saving you about 20% electricity. By tapping into your alternator, this new EcoFlow Alternator Charger delivers up to 800w to quickly top off your power stations. No more of that slow 100w cigarette lighter nonsense (which are prone to melting). The installation could not be easier. Tighten down the included cables onto your battery terminals, including the 125a fuse that comes in the box on one end. Then route the 5 meter cable (6 awg) to the inside of your vehicle, where you can either place the charger directly on top of your power station or mounted from a bracket screwed into a wall. With the included 1 meter XT150 cable, you can securely lock onto one end of the charger and the other end into your battery. The connection is solid and even requires a special removal tool (included in box) to push open the prongs clamping down on the connection points. The entire unit is metal and feels hefty. Surprisingly heavy. The cables and thick and beefy, so they can stand up the high amperage coming through. In the EcoFlow app, you can control how fast or slow you want to charge too, up to 800w. This is critical for those with smaller alternators. The 3-in-1 features include 1) power station charging at 800w, 2) reverse charging, so your EcoFlow battery can charge your car's 12v lead-acid battery, and 3) maintenance mode (100w) to ensure your 12v vehicle battery doesn't die (keep it always juiced up). There is a wifi dongle and a yet-to-be used ethernet port that is included as well. Presumably, those will unlock more options later, but right now, they are not functional or needed yet. Talking to the EcoFlow reps, I've also learned they are currently undergoing testing this charger with Teslas, both the old ones with 12v batteries and the new ones with 16v batteries. If those can work, it will open up a whole new world beyond ICE vehicles. Use cases for this include weekend camping trips. I can toss a Delta 2 battery in my trunk, then once it depletes at camp, I can throw it on the charger and have a fully charged Delta 2 again in just over an hour. The speed is incredible. It's really as simple as plug and play. Solid build quality. Slim profile for easy mounting. Great included cables, mounting accessories, fuse, and cable removal tool. And being a DC-to-DC charger, I can now avoid the dreaded modified sine wave issue that many vehicle's AC inverters have, which doesn't provide clean power to the EcoFlow battery, so they can't be charged that way. I can now charge directly and not worry about finding pure sine wave inverters, nor worry about the inversion losses of using an AC inverter to begin with (20% or so). So far, I've seen this product is only compatible with EcoFlow batteries that have either an XT150 port or an extra battery port that lets you use the EcoFlow Smart Generator Adaptor, which transforms the extra battery port into an XT150 port. So Delta 2, Delta 2 Max, Delta Pro, and Wave 2 batteries work. You can even directly charge the extra batteries without the main battery unit itself using this charger. Possibly, the EcoFlow Power Kit batteries are compatible too (using the Smart Generator Adaptor), though this charger is redundant to the built-in alternator charging capabiities of the EcoFlow Power Kit system already. This unit is a gamechanger for camping, off-roading, or long road trips. ... show more

  • Works after Firmware update that Ecoflow has to manually send you.
Hefty , quality built bit of kit. Comes with everything you need to charge up your Delta Style Powerbank. However, my Delta Max 2016wh would not communicate with the charger and actually drained by 50% overnight. I spoke with Tech Support / Customer service that have always been great with any issues that I have had and they are replacing my Delta Max under Warranty. I am sure this will be a good addition to my boondocking camping style. ... show more
