ETAKER 1000W Alternator Charger, DC to DC Charger for Portable Power Stations, Solar Generator, Charges 1kWh in 1H，Sutible for RVs,SUVs,Diesel Cars, Boats

I have checked all the settings in the app. Getting great voltage on the alternator port and DC port. But it will not charge the battery no matter what settings I set. Very disappointed. Would be the perfect product if it worked. No other products like it on the market. Update: I reached out to support and they worked with me and we diagnosed that I had a failed unit. They sent a new one out quickly and its working as intended. Will definitely recommend reaching out to support with any problems! This is perfect for my use case. I have a Ford Transit work van with a 48v LFP battery and inverter. The van alternator charges the 48v battery and it also has an additional 12v output for accessories that won't drain the main van battery but instead pull from the 48v battery. Great all-in-one unit!

The F1000 does what it is supposed to do when properly set up. It's exactly what I needed. I'm an idiot with no experience with these type things and have come to the hard realization that I have become the stereotypical parent who calls their kids for techy help. In my case it was ETAKER customer service which is outstanding. I dealt with Lueng who was extremely helpful and patient. He didn't talk down or use techno babble, he sent screen shots of what to check and what settings were required. I'm using this in a 2025 Kia Carnival to charge portable solar batteries while road tripping. The Kia's built in AC port is only 100watts and the minimum my batteries will accept is 300watts. I originally was going to use a larger Power converter until I read about possible damage to the alternator. I can also run solar panels through this when parked. Another nice feature is it can be reversed to charge your car battery from your portable battery if ever needed. The addition of exceptional customer service made this a no brainer.

I wanted to like this product. First of all once I got it setup I was camping in my overlanding vehicle and the voltage cutoff didn’t work and it killed my starting battery. Then there’s the whole ordeal with the proprietary plug that the company doesn’t even sell the cord for. Then theres the fact that now the app doesn’t detect the etaker f1000pro and I can’t adjust any settings. I wish I could return it or get a refund. I have tried contacting etaker support and they have not helped.

This is an amazing product! Hooks up very easy and fast, works amazing! We have a camper van that we travel in and 200 watts of solar on the roof. But we have ran out of power so many times due to weather conditions. This is a total game changer, while we drive we hit the button on and we get almost 500 watts of power going into our power station without the solar. If we add the solar you can get up to 800 or more. I’m so happy with this product. I can’t say enough about it!

I have a 2017 RAM Promaster City, Bluetti AC180, and 350 watt of solar panels. I was getting power starved on my camping trips and wanted something to supplement my system. I picked this product because it does both solar and the alternator while many of the others I saw only did alternator charging with no solar. Pros: This product feels well built and relatively quiet. The cable included feels durable and cable is long. The cable sleeve included was terrible as it unravels at the ends. I love that it allows for alternator and solar charging though I don't see evidence of it doing both at the same time. The install was easy but I did have to modify the round cable connector as it wouldn't find around any battery terminals. On the 500 watt setting, it charges a steady 410 watt to my battery. The PV port on my battery only does 500watt max so 410watt input is fine with me. Cons: I dislike that the on/off button also affects the solar charging. If the device is off, the solar wouldn't charge my battery. So I have to keep the device permanently on to be able to let my solar work. Because of leaving the device always power on, I depend on the vibration detection on/off setting to turn the alternator charging on and off. The vibration detection on/off setting is a hit or miss. I've notice times where it didn't kick in so I drove around without it charging my battery. I thought maybe I had the vibration setting off but did verify it was on. I notice that the vibration detection often doesn't work after leaving the car overnight. I have to turn the device off then back on for alternator charging to kick in. Once on though, it seems to automatically shuts off fine. The battery will continue to charge after the car is shut off but the device usually turns it self off in a few mins. I've had the device shut off while I was idling the car. So the vibration detection has to be turned off if idling. Things I'm still watching for: I have 350 watt of solar and it usually puts out a steady 260 watt output. After plugging it into the Etaker, I notice that it hasn't been performing as well as it should. I won't blame the device just yet as winter rolled in and the Sun is sitting lower in the horizon now but I will revisit this review in the summer. Currently I only see 150 - 180 watt output from my solar. One thing to keep in mind about solar is to pay attention to how it's wired. I wired my two solar panels as series directly to my AC180. Works great. But to use with the device, I had to rewire my solar panels to parallel. I tried keeping the series setup and connected it to the charger. However, it was 2 volts over spec and I saw the charger turns itself off periodically. So I had to rewire my setup to parallel and it has worked fine since. I did notice a 30 watt average decrease in output after going to parallel though. I did debated whether I should return this product. I wanted something that just works and that I didn't have to worry about it. However, I feel I have to constantly monitor the charger and make sure it actually turns on. But I all I really have to do is flip it on/off so it isn't a huge deal. Just be mindful where to mount the device as you may need to access it often. There wasn't many other alternator/solar chargers on the market so I think I'll keep this for now though I still feel I got to keep an eye out for something better to upgrade to. Overall: My goal was to be less power starved and this charger was successful in that regards.

It so far does what I bought it for which is to add battery capacity to my power station but having to use an app that I can't get to work to adjust the settings just plain sucks. I wish it had a screen where you could make the changes instead of a worthless app. It won't pair with my phone no matter what I do but out of the box with no changes made it transfers 450 watts from my 400 ah power bank into my power station so I can run an electric heater all night when I'm camping. That is what I wanted it for otherwise I would send it back so beware if you need to use the app.

Did not do what it should not charge an battery pack up using the plug on the side only the power bank of there make

It didnt work with me I saw the electricity going in, but it doesn’t go out so I don’t know whether this one that I receive it manufactures problem or all the products like this.!
