AC180 vs Charger 2 Specs
Power Output
The AC180 delivers 1800W of continuous running power and can surge to 2700W for short bursts. This allows you to run larger appliances like microwaves or power tools. The Charger 2 does not output power to your devices. Instead, it provides up to 1200W of charging input to replenish your power station. You use the AC180 to run loads, while the Charger 2 speeds up the refill process via alternator or solar input.
Energy Storage
The AC180 contains a 1152Wh LiFePO4 battery. This capacity stores enough energy to run essential home devices or campsite gear for hours during an outage. The Charger 2 has no internal battery. It is a charging controller that manages energy flow from your car or solar panels into your station. You need the AC180 for actual energy storage, while the Charger 2 is an accessory that helps keep that storage full while you are on the move.
Portability
The AC180 weighs 37.4 pounds and measures 13.4 x 9.72 x 12.5 inches. It is designed to be moved occasionally but is substantial enough to stay in a vehicle or garage. The Charger 2 is significantly lighter at 3.5 pounds and measures just 10.4 x 6.6 x 2.7 inches. You can easily mount it in a car trunk or under a dash without taking up much space. If you need a lightweight component to add to your setup, the Charger 2 is the clear winner.
Charging Speed
The AC180 can fully recharge from empty to 80% in just one hour using its 1440W AC input. Solar charging takes 2.8 to 3.3 hours with 500W input. The Charger 2 adds 1200W of charging power via dual inputs, combining 800W from the alternator and 600W from solar. This dual input capability makes it 13 times faster than standard car cigarette lighter charging. You get the fastest AC refill with the AC180, but the Charger 2 offers rapid replenishment while driving.
Vehicle Integration
The Charger 2 is built specifically for vehicle use. It monitors battery voltage to prevent draining your car battery when the engine is off. It also communicates with smart alternators using a D+ signal. The AC180 can jump-start a car battery via its BAT port, but it does not manage vehicle electrical systems. If you want to charge your power station while driving without risking your car's starter battery, the Charger 2 provides the necessary vehicle-specific protection and integration.
Which BLUETTI Model Fits Your Needs
You need backup power for home outages
The AC180 acts as a UPS with a 20 ms transfer time, keeping essentials running during blackouts. Its 1152Wh LiFePO4 battery provides substantial storage, and the 1800W output handles multiple devices simultaneously. You get reliable energy independence without relying on external fuel sources.
You want to charge your power station in a car
