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

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!

Charges my Anker Solix 1000 4 times faster than DC charging alone. My Frig/Freezer will never run out of power. Turns off when vehicle is turned off and turns on as it should when vehicle moves. Easy to install. Build quality is solid. Made of aluminum.

WARNING! Do not connect to a 12v Lithium Battery before running the apo. DC Output is defaulted to 24V. If you are charging a 12v Lithium Battery please download the app and make sure the DC OUTPUT is adjusted to 12v, set to "Charge Battery". I connected the DC output before I ran the app/changed settings, it blew my 12v battery monitor. Other than that, this DCDC Charger is awesome! Reverse charging is possible thru the app. My truck's battery always discharges to 12.3v after 5 days so I just "Activate Car Battery". Once it reaches at least 12.6v I'm able to start my truck. Bluetooth connectivity is awesome. My truck is in the driveway and my bedroom is all the way to the back and I can still control the charger.

Great product for use with my solar generator. Having the extra charging from the car battery is such a nice feature when tied to the solar input makes it quick to have the system fully charged while traveling.The software interface could be improved for the configuration process. Or if possible a pull down menu that automatically configures for various standard units.Advice to all - READ and Re-READ the manual as there are good hints hidden in the various sections.

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.

Great to have a dc to dc charger that not only offers fast charge directly from your alternator but also from solar. No way you could be that. It's literally the best of both worlds if your looking very convenient way of having your power bank charged. It's tiny, all metal and well built so if you're thinking of buying a dc to dc and a solar inverter separately. You should definitely give this a shot.

This is the worst. It would connect to the app for a bout a week, then suddenly the app would not connect to it. I removed the app from my phone, attempted to repair it. It will not pair. It will power on when I push the power button, but will not charge. It will not shut off even when I hold the power button down. The documentation is horrible. When it did work, the vibration auto on feature was flaky and didn't work half the time. I've apparently wasted my money.Update August 1 2025. I contacted etaker support 10 days ago. I got 2 responses where they told me to go through pairing procedure exactly as stated in the manual. I had already tried that. They now claim they are trying to recreate my problem in their lab. K. I don't know how they're going to do that. It feels like I'm getting the run around.
