Review: It works well for my dad and my babies! - 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!
Review: Solid Product, Great Price - 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!

## Features

- 8x Faster Than a Cigarette Lighter Charger. The 800W Alternator Charger replenishes 1kWh to a portable power station within a 75-minute drive. It capitalizes on surplus alternator energy, enabling you to power essential devices like phones, coffee makers, and lights while on the move. *Note: Alternator capacity varies by vehicle - Please verify with your manual (or the alternator's manual) that the alternator's output supports the alternator charger's maximum power draw for safe operation.
- 3-in-1 Functional Design. Three integrated features that charge your portable power station, keep your vehicle battery in peak condition and act as a jump starter when you need it most.
- Easy-to-Install System. Enhance your overlanding and vanlife with EcoFlow power stations. Perfect for supplementing your 12V RV house battery, and extending your runtime. It's not just for use in your van, our compact and lightweight power stations can be taken off-grid and used to power the outdoors. *Note: A DELTA Pro to Smart Generator Adapter is required to connect the Alternator Charger with DELTA Pro and DELTA Pro 3.
- Access the EcoFlow App Anywhere. Easily view your vehicle's energy usage in real-time, including power consumption and charging status, anywhere. Monitor and manage your entire vehicle, from temperature to appliance power.
- 2-Year Service&Vehicle Protection. Utilizing GaN technology, the DC-DC Charger efficiently converts electricity, preventing overheating even at high speeds. It safeguards your vehicle from reverse polarity, overcurrent, short circuits, and voltage abnormalities.

### ⭐⭐⭐⭐⭐ HOW TO INSTALL, AND THE ADAPTOR YOU WILL NEED
*by S***E on January 8, 2026*

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.
