EF ECOFLOW 800W Alternator Charger, 3-in-1 Fast DC-DC Charger for Portable Power Stations, Car Battery Charger & Jump Starter 8× Faster Than Cigarette Chargers, Charges 1kWh in 1.3 hr

My parents are on a road trip with their grandchildren. One of my grand child really loves milk so we use an ecoflow power bank to power our milk warmer. I decided to get this alternator charger to allow my parents to keep the powerbank charged on the road! Installation was fairly easy! My dad drives a Camry and it wasn’t too hard to route it through all the compartments and run the cables to the trunk. It definitely was long enough for the Camry! Now they are on the road and it seems like the ecoflow power bank is constantly topped up with zero issues! Bonus! My kids loved playing with the box!

I had been eyeing ecoflow products for a while and when everything went on sale for Prime Day I decided to finally give it a shot. My plan is to install this combination in my ‘03 4Runner along with some panels on the roof once I have a roof rack installed. The idea is to essentially turn my 4Runner into an off grid dwelling so this will be powering a diesel heater and some electronics during long overlanding adventures. So far though I have just been using it at home to charge electronics and stuff so I can get a feel for how long it will run. I am very impressed with the build quality of this thing, it looks and feels solid and is extremely quiet when charging AC from the wall and powering DC via USB ports though I suppose that’s an easy load for this thing. The app is great and the ability to track power use over time has allowed me to experiment at home to get a feel for things which is a big plus. It’s about the size I had imagined it would be not super small but also not super large - it is heavy but it’s a battery so that’s basically expected. I can’t wait to get this installed along with my alternator charger but I will have to limit charging speed at first because you pretty much shouldn’t use 800W charging off nearly any stock alternator; you should get a high output alternator for that and that’s my next purchase!

Once up and going, it is worth 5 stars. Getting there was a pain! I have a Delta Pro 3.6kWh system and wanted to connect the alternator charger to it. However, the documentation was not clear. Then after much googling, I learned I needed to buy an adapter (ummm, it should come with it). You need the "smart generator adaptor compatible with Delta Pro" and can find several here on Amazon. I just bought the cheapest and it worked. The cable from the battery plugs into the alternator charger. Install it with the icon facing up and match the icon on the cable to the icon on the alternator charger. You can also tell which one because the cable from the battery does NOT have the small communications pins in the center. Then take the cable that came with the alternator charger and plug one side into the alternator charger (to the connector that HAS the small communication pins in the center and be careful to do it properly). The other end of this cable plugs into the adaptor mentioned above, and then that adaptor plugs into the battery port (I used battery port 1) on the back of the Delta Pro. It can only plug in one way, and the cover on the Delta Pro is just rubber and hinges down out of the way.

This product does not work with the Ecoflow Delta Pro as advertised. When I tried to connect them, I discovered there is no port on the Delta Pro. You actually need a separate $70 adapter — something never mentioned until after purchase. I attempted to buy the adapter directly from Ecoflow, but my orders kept getting mysteriously canceled. Customer support offered no real help beyond “try a different credit card.” Even when my wife tried ordering with a different account, the order was canceled again. I had my wife order the adapter on a different device and credit card and the same thing. Now I just I received an automated emails saying the “trouble report” was closed. The result: I’m stuck with a Delta Pro I cannot charge and an expensive alternator charger that’s useless. Between misleading advertising and the worst customer support I’ve ever experienced, I strongly recommend choosing a different manufacturer if you value transparency and meaningful support.

I'm using this to expand the storage capacity of my Ecoflow Delta 3 plus. I have this running in 24v mode connected to a pair of 100AH LiFePo4 batteries. I plan to expand that battery string to 4 and eventually 6 to get longer runtime at a lower cost than Ecoflow's add-on batteries. This works well for what I wanted accomplish. The device itself is pretty large for what it does. It stays cool. I fully dislike having to use a separate tool to disconnect the cables. There are many existing locking cable harness connector designs that require no tools. One time, the mobile app showed some communication issues with this device and suggested that I reset it at the power button. A reset took care of the issue, but it could happen in a less convenient time.

This thing is a beast and just works great!

I use an ecoflow delta 2 in my camping rig. They talk about controlling with the app, being able to charge the car battery and jump start if needed, but to do this you need to buy the Xt60i cable for another $99 since the included Xt60i cable does not allow you to use these settings. You also cannot adjust the power output so that the alternator charger does not tax your vehicles alternator. Using the included cable also means having to disconnect your solar panel. It just adds more steps to use this and more wear on both the cable and the delta2 input having to switch when driving and parked. I also believe that if you use this with the xt150 cable you lose the ability to use a smart extra battery.

Ótimo produto, a única falha é a ecoflow não informar que para ligar na Delta Pro tem que comprar um adaptador
