EcoFlow 500W Alternator Charger
Overview
The EcoFlow 500W Alternator Charger turns your vehicle's drive time into charging time, recharging an EcoFlow portable power station up to 5 times faster than a standard 12V cigarette socket. Top up around 1kWh of energy in just 2.1 hours of driving, so you arrive at camp, the bach, or the worksite with your power station ready to go.
Built for SUVs, utes, vans, motorhomes, and 4WDs, the unit uses GaN (Gallium Nitride) technology for efficient, cool-running operation and includes multiple safety protections, including undervoltage cut-off to protect your starter battery. Compatible with EcoFlow RIVER and DELTA Series power stations, as well as most third-party portable power stations with an XT60 input.

Top Up 1kWh in Just 2.1 Hours of Driving
Plug in, drive, and arrive charged. The 500W Alternator Charger taps into the excess energy your alternator already produces while you drive, then channels it through an efficient onboard DC-DC converter to recharge your EcoFlow power station up to 5 times faster than a traditional cigarette outlet. For NZ road trips, weekend trips to the bach, hunting and fishing missions, or short commutes to a worksite, this means you stop wasting drive time and start using it.
5x Faster Than a 12V Cigarette Socket
A standard 12V vehicle outlet typically tops out around 100W of useful charging power. The 500W Alternator Charger delivers up to 500W, giving you significantly faster charge times and making short drives genuinely useful for keeping your power station full. Ideal for tradies between job sites, campers heading off-grid, and anyone who needs reliable power without waiting hours for a top-up at camp.
Built for NZ Vehicles and Conditions
Compatible with both 12V and 24V vehicle systems, the 500W Alternator Charger suits the most common Kiwi vehicle types, including SUVs, utes, vans, 4WDs, and motorhomes. Plug-and-play installation with the included 5m input cable, fuse cable, and installation hardware means a clean fit without aftermarket modifications. The GaN-based design runs cool, reliable, and stable under sustained loads.
Safe and Reliable on Every Drive
GaN (Gallium Nitride) technology delivers high efficiency with low heat, making sustained 500W charging stable even on long drives. Built-in safety protections include undervoltage cut-off (which prevents your starter battery from being drained), overvoltage, overcurrent, short-circuit, reverse-polarity, and over-temperature protection. The unit only draws power when your engine is running, so it cannot accidentally flatten your vehicle's battery overnight.
Want Reverse Charging and Battery Maintenance?
The 500W Alternator Charger is technically capable of reverse charging your starter battery and acting as a battery maintainer, but these modes require an optional XT150 cable that is not included with this unit. If you specifically want a charger that ships with everything needed for full 3-in-1 capability (charging, reverse charging, and battery maintenance), have a look at the EcoFlow 800W Alternator Charger, which comes with the XT150 cable and delivers more power for larger setups.
3-Step Easy Installation
The 500W Alternator Charger comes with everything needed for a clean install: 5m input cable, fuse cable, output cable, mounting hardware, and a cable puller. Connect the fuse cable to the vehicle battery, route the input cable to the charger, then plug the output cable into your power station. Detailed install instructions are in the box. For permanent installation in motorhomes, caravans, or work vehicles, we recommend a qualified NZ auto-electrician.
Important Installation Notice
Alternator output capacity varies by vehicle. Please check your vehicle or alternator manual to confirm it can support the charger's maximum 500W draw before installation. For permanent installation in vehicles, motorhomes, and caravans, we recommend using a qualified auto-electrician to ensure safe, compliant wiring.
Frequently Asked Questions
How fast does the 500W Alternator Charger recharge my EcoFlow power station?
It can top up around 1kWh of energy in approximately 2.1 hours of driving, which is up to 5 times faster than a standard 12V cigarette socket. Actual speeds depend on your vehicle's alternator output and the specific power station you are charging.
Will it work with my vehicle?
The 500W Alternator Charger is compatible with both 12V and 24V vehicle systems and works with most SUVs, utes, vans, 4WDs, and motorhomes. Always check your vehicle or alternator manual to confirm it can supply 500W of output before installation.
Which EcoFlow and third-party power stations is it compatible with?
It works with EcoFlow RIVER and DELTA Series power stations, as well as most third-party portable power stations that accept an XT60 input.
Does the 500W Alternator Charger really do reverse charging and battery maintenance?
The hardware supports these modes, but they are not available with the included XT60 cable. To unlock reverse charging (using your power station to charge your vehicle's starter battery) and battery maintenance (keeping a parked vehicle's battery healthy), you would need an optional XT150 cable used with an EcoFlow DELTA Series power station. If you want full 3-in-1 capability included in the box, consider the EcoFlow 800W Alternator Charger instead, which comes with the XT150 cable as standard.
Can I install the 500W Alternator Charger myself, or do I need an auto-electrician?
The unit ships with the cables, fuse, and hardware needed for installation, and EcoFlow describes it as a 3-step process. A confident DIYer with vehicle wiring experience can install it. For permanent installs in motorhomes, caravans, or work vehicles, we recommend a qualified NZ auto-electrician to ensure safe and compliant wiring, especially for high-current connections to the starter battery.
