## Description

desertcart.com: EF ECOFLOW DELTA2 Portable Power Station with 800W Alternator Charger : Automotive

Review: Powerful combo - even if you don't care about alternators! Create a mini power wall. - Instead of hooking this to your car's alternator/battery, just hook it to a Lithium battery bank to add capacity to this EcoFlow Delta 2 for about 33% of the price of the brand name extra batteries. Low cost LiFePO battery packs are all rage now, most come with bluetooth enabled BMS (Battery Management System) and at the time of this writing are about 18 cents per watt/hour or $180 per kwh. (By comparison the EcoFlow extra 2kw/h battery is about 54 cents over $540 per kwh), so you can get a lot of extra storage going this route for . There are some minor downsides but if you are good with hooking up cables, this "alternator charge" is an awesome accessory that complements the Delta 2. So as mentioned this combo enables you to add external / low cost LiFePO battery packs for a fraction of the cost of stacking EcoFlow external batteries. I had this open and running with an external mid-range 24V 100 Ah LiFePO battery that for ~$500 was able to add 2.4 kwh of capacity - this "alternator" gizmo will charge and maintain the external battery, then will reverse and use it as a power source. Right now the app is showing an 800+ watt charge current (30A @ 26v) which will bring this batter from 10% to 100% in about 3.5 hours. Meanwhile the Delta 2 is doing it's normal thing with all it's fancy ports. There's a "maintenance" mode that will keep the external battery bank topped off at 100 watts max. My use case is I needed something to get a small home through an extended power outage that works like a generator for hours at a time without having to actually run a generator all the time. I have a very quiet Honda Eu2200i that can recharge everything rapidly for an on/off duty cycle and quiet power through the evening and most of the day. I can backfeed the EcoFlow Delta into my home's electrical after disconnecting the mains. Works great! Everything works well in the app - both devices are configured/monitored in the same EcoFlow app. The only thing I noticed that may raise an eyebrow is the energy conversion rate from AC input to the EcoFlow Delta 2 to the "Alternator Charging device" to output to the DC charging wattage out to the battery has about a 25% loss, mostly on the AC conversion at the Delta 2. Ok, now that I'm prepared, I'm sure my power will never go out again like the storm that we just had. Better to have it and not need it, then to need it and not have it! :-)
Review: Game Changing Set-up - So far so good! This is to replace a broken River Pro which had that some functions didn't work. I've only used it a few times but it worked out amazingly! I'm an overlander where I need power during camping trips. The struggle with power station is charging it back up. I have solar panels but it charges slowly. I also drive to different spots where the car charging is also slow. The 800w alternator charger is a total game changer for my use case! I charges super fast when I'm driving or idling like I'm charging at home with 115v outlet. Now with a smaller battery set up and faster charging, I lost weight and eliminated the stress of recharge! Huge win.

### ⭐⭐⭐⭐⭐ Quality product for the price
*by E***R on March 23, 2025*

Great quality product and price point!! I used it in the last hurricane when my power went out and it easily powered my refrigerator for most of they day before needing to be recharged. The app is very easy to use and has several smart features. The most important one is regulating how much power it pulls from your alternator. I have a Toyota Camry so it's good not pull maximum draw off a smaller alternator. I liked this one so much that I bought the Delta pro 2 as well to power additional devices in the future. Word of advice, these often go on sale with deep discounts so watch for sales.
