Frequently Asked Questions

Will this product damage the alternator, starter battery, or affect the overall lifespan of the vehicle?

No, the 800W alternator charger's charging logic does not rigidly apply 800 watts. Instead, it depends on the power surplus of the car's alternator. It ensures the alternator is not overloaded, allowing up to a maximum of 800 watts without harming the car's battery.

Will this product consume more fuel (i.e. affect gas mileage) when used?

The product uses the electricity generated by the car's alternator. Even if all the electrical devices inside the car are turned off, the alternator still generates electricity while the car is running. The alternator charger utilizes the surplus electricity generated by the car's alternator and stores it in a portable power station through the charger. The impact on fuel consumption is very minimal.

Do I need to drill holes to install this product? Will it cause any damage to the vehicle?

Drilling is not required for installation. The wiring connection to the alternator at the front of the car does not need drilling and will not damage the vehicle. It can simply be wired through the firewall near the driver's seat. The alternator charger can also be installed using methods that do not require drilling.

Is this product suitable for DIY installation?

The installation of the alternator charger is not very complicated, and it is feasible for professional users with some hands-on ability to install it themselves. However, it is still recommended to contact professional personnel from related workshops for installation. Installation advice: When wiring, avoid high temperature, sharp, and friction-prone areas, and securely fasten the cables to avoid cable wear or loose connections caused by cable movement. The alternator charger may generate high temperatures, so avoid covering the product. After use, avoid immediate direct contact to prevent the risk of burns.

Is it normal for the alternator charger to get hot?

Yes. The alternator charger may generate high temperatures, so avoid covering the product. After use, avoid immediate direct contact to prevent the risk of burns.

How long does it take to fully charge a DELTA Series product?

DELTA 2 (1kWh) - 1.3 hr; DELTA 2 Max (2kWh) - 2.6 hr; DELTA Pro (3.6kWh) - 4.8 hr; DELTA Max 2000 - 2.6 hr; DELTA Max 1600 - 2.1 hr; DELTA 2 Extra Battery - 1.3 hr; DELTA 2 Max Extra Battery - 2.6 hr.

Compared to charging via the cigarette lighter, what advantages does the alternator charger offer when used in a vehicle?

The charging power is significantly increased. The charging power of a cigarette lighter is about 100W, whereas the alternator charger can support charging continuously at a high power of 800W during driving for portable power stations, which is 8 times the power of a cigarette lighter.

Solution to the problem that the EcoFlow WAVE 2 add-on battery does not work with the alternator charger.

Please first connect the EcoFlow WAVE 2 add-on battery to EcoFlow WAVE 2, and then upgrade the firmware to the latest version through the app.

How can I tell if the alternator charger is applicable to my car?

The alternator charger operates with an input voltage of 11V-35V, so in theory, any vehicle with a starter battery operating on a 12V or 24V voltage can use this product.

What protections are in place for the alternator charger in a car?

Reverse polarity protection/overcurrent protection/short circuit protection/overvoltage and undervoltage protection.

How many operation modes are there for the alternator charger?

1. Charging mode: Strictly speaking, it is the car's alternator charging the battery of the portable power station, with the car's battery acting as a load to conduct the current. 2. Reverse charging mode: The portable power station charges the vehicle starter battery or the RV house battery reversely at a rapid rate, with a relatively high current. 3. Battery maintenance mode: Similarly, the portable power station charges the battery, but with a smaller current.

What does the indicator light on the alternator charger mean?

Green light: Charging mode; Blue light: Battery maintenance mode; White light: Reverse charging mode; Yellow light: Unbinding success indicator; Red light: Device failure indicator.

How does the alternator charger automatically start and stop?

The alternator charger operates based on voltage recognition, and it can charge when the input voltage is greater than 13V.

What type of vehicles are suitable for installation? Do they all reach the maximum charging power of the alternator charger?

Based on the principle of the alternator charger, gasoline vehicles are the most suitable for use, while hybrid and range-extended vehicles can also be adapted. The specific operating power depends on the surplus power of the vehicle's alternator, so the charging power may fluctuate. Additionally, some older or special models may not work properly due to overall low voltage.

What is the input of the alternator charger?

Charging mode: 11V-35V, 76A Max Battery maintenance mode: 40V-60V, 3A Max Reverse charging mode: 40V-60V, 21A Max

What is the output of the alternator charger?

Charging mode: 40V-60V, 800W Max Battery maintenance mode: 13.8V/27.6V, 100W Max Reverse charging mode: 13.8V/27.6V, 800W Max

What are the operating and storage temperatures of the alternator charger?

Operating temperature: โ€“4โ„‰ to 140โ„‰, Storage temperature: โ€“22โ„‰ to 158โ„‰

Will installing an alternator charger affect my car's warranty?

Please confirm with your vehicle manufacturer regarding vehicle warranty issues.
