Differences Bluetti AC180 vs Bluetti AC70
Below is a summary of the specifications:
Battery Capacity, Expandability, and Battery Lifespan
The Bluetti AC180 features a large 1,152Wh LiFePO₄ battery, giving it the edge in long-term usage and runtime. It is ideal for powering larger appliances or multiple devices simultaneously during longer trips or extended outages. The Bluetti AC70, while still equipped with a robust 768Wh LiFePO₄ battery, offers less capacity, making it better suited for shorter excursions or light-duty tasks.
In terms of battery chemistry, both models use Lithium Iron Phosphate (LiFePO₄), renowned for its thermal stability, safety, and longevity. The AC180 delivers over 3,500 cycles to 80% capacity, while the AC70 maintains a strong 3,000+ cycles, still well above industry averages.
Neither model supports external battery expansion, so users must choose based on their anticipated energy demands.
Winner: Bluetti AC180
With higher capacity and longer cycle life, the AC180 wins this category for those requiring extended off-grid power and reliability.
Power Output and Appliance Compatibility
When comparing output capacity, the difference between the two models becomes even more evident. The AC180 delivers a continuous 1,800W AC output and can handle surges up to 2,700W, which allows it to power high-wattage devices such as electric cookers, kettles, refrigerators, or even power tools. It also features Power Lifting Mode, which supports resistive loads that exceed its rated output.
The AC70 delivers a more modest 1,000W continuous output and 2,000W surge, suitable for small kitchen appliances, TVs, lights, laptops, and CPAP machines. While reliable for basic usage, it’s not designed for high-demand scenarios.
Winner: Bluetti AC180
Its robust inverter and surge capacity offer broader compatibility with household and heavy-duty appliances, ideal for professional or full-time off-grid users.
AC Charging Speed and Solar Input
In terms of AC charging speed, the Bluetti AC180 leads again with an impressive 1,440W input, charging from 0–80% in approximately 45 minutes, and full charge in about 1.3 hours. This ultra-fast charging is ideal for users on tight schedules or in unpredictable environments.
The Bluetti AC70, while slower, still offers a respectable 850W AC input, also achieving 0–80% in roughly 45 minutes, with full charge around 1.5–2 hours. This performance is commendable for its class and size.
Both models support 500W solar input with MPPT (Maximum Power Point Tracking) controllers and a voltage range of 12–60V, ensuring efficient recharging from portable solar panels like Bluetti’s PV200 or PV350.
Winner: Bluetti AC180
The higher AC input means faster charging in more situations, making the AC180 a better choice for heavy users.
Portability and Size Comparison
The Bluetti AC70 is significantly lighter at just 10.2 kg, making it an excellent choice for those who need true portability—think solo campers, digital nomads, or photographers constantly on the move. It also has a smaller footprint of 314 × 209 × 256 mm, ideal for tight spaces in cars or small tents.
The Bluetti AC180 weighs 16 kg, and although it features a strong carrying handle and balanced design, its bulk makes it more suited for semi-permanent use, such as in RVs, backup power setups, or workstations.
Winner: Bluetti AC70
Its compact and lightweight design make it the more travel-friendly choice, especially for short-term use or frequent relocation.
Connectivity and Smart Features
One of the biggest differentiators is smart connectivity. The Bluetti AC180 includes Bluetooth and Wi-Fi, providing full control through the Bluetti app. Users can monitor battery levels, control AC/DC outputs, enable ECO mode, check charging status, and update firmware remotely.
The Bluetti AC70 does not support any wireless connectivity or app integration. While its manual controls are simple and user-friendly, it lacks remote accessibility and energy management features.
Winner: Bluetti AC180
The smart control functionality adds a premium touch, giving users real-time insight and remote access—a major plus in modern setups.
Ports and Output Variety
The Bluetti AC180 offers a comprehensive array of ports. It includes one 100W USB-C PD port, four USB-A ports at 5V/3A, one 12V/10A car port, two AC outlets rated at 1,800W combined, and a 15W wireless charging pad on top. This combination supports everything from smartphones and laptops to larger kitchen appliances and battery-powered tools.
The Bluetti AC70 features two USB-C PD ports at 100W each, two USB-A ports at 5V/3A, one 12V car port, and two AC outlets at 1,000W. It’s ideal for charging multiple gadgets and running small appliances, though it lacks the wireless charging pad.
Winner: Bluetti AC180
The wider port variety, additional USB-A ports, and inclusion of wireless charging offer better versatility and modern usability.
