Quick Answer
For most buyers it's the Bluetti AC180P. At $1,169 for 1,440Wh, it gives you the most stored power per dollar of the three units in this comparison, and by a wide margin.
Go the EcoFlow Delta 3 Plus if charging speed, surge headroom or future expansion matter more to you than raw capacity. The Delta 3 1500 is the pick when you want EcoFlow's tech with the biggest battery of the lot.
The Versions Sold in Australia
The names can trip you up, so let's sort that first. Neither "AC180" nor "Delta 3" is a single product on Australian shelves any more.
Bluetti AC180 and AC180P
The unit on the shelf today is the AC180P, the upgraded version of the original AC180. It carries a bigger battery (1,440Wh against the old 1,152Wh) in the same body. The full differences are in the AC180 vs AC180P guide if you're curious.
EcoFlow Delta 3 Plus and Delta 3 1500
The Delta 3 sold here comes in two versions: the Delta 3 Plus (1,024Wh, $1,599) and the Delta 3 1500 (1,536Wh, $1,899). Same 1,800W inverter, different battery sizes, so your choice is mostly about capacity. They're compared head to head in the Delta 3 1500 vs Delta 3 Plus guide.

Capacity and Runtime
Capacity is where the AC180P earns its keep. You get 1,440Wh for $1,169. The Delta 3 Plus gives you 1,024Wh for $430 more. Even the 1500, with its bigger 1,536Wh pack, only edges the Bluetti by 96Wh and costs $730 extra.
What does that mean for your setup at camp? Reckon on about 85% of the rated capacity making it to your gear. On a camping fridge drawing an average of 60W, that's roughly 20 hours from the AC180P, 14 from the Delta 3 Plus, and 21 from the 1500.
All three will run your laptop, lights, drone batteries and phone chargers without breaking a sweat. The guide on running a fridge from a power station has the full maths so you can size yours properly.
Output and Surge Power
All three put out 1,800W continuous through pure sine wave inverters, so day to day they run the same gear: your fridge, the coffee machine, most power tools.
The gap is surge. The EcoFlows spike to 3,600W where the AC180P tops out at 2,700W. That extra headroom helps when your compressor fridge or saw draws hard on start-up.
The EcoFlows also carry X-Boost, which lets them run simple heating-element appliances rated up to 2,400W, think your kettle and toaster, by trimming the power delivered. The Bluetti sticks to its 1,800W budget.
Charging Speed
This one goes to EcoFlow. The Delta 3 Plus refills from flat in 56 minutes on AC power. The 1500 takes about an hour and a half, and the AC180P needs 1.3 to 1.8 hours in Turbo mode.
If you're topping up the night before a trip, that gap barely matters. If you decide to head off at lunchtime, it does.
Off-grid, the Delta 3 Plus pulls up to 1,000W of solar and can refill in about 1.5 hours of strong sun. The AC180P and the 1500 both cap at 500W, with the Bluetti taking around 3 hours in ideal conditions. Browse the portable solar panels range to pair with your setup.
Battery Life and Warranty
All three use LiFePO4 chemistry, the safe, long-life stuff. The Delta 3 Plus is rated best at 4,000+ cycles to 80%, the AC180P close behind at 3,500+, and the 1500 at 3,000+ cycles to 70%.
Charge yours a few times a week and it'll still be serving you years from now. All three carry 5-year warranties with local Australian support.
Weight, Ports and Everyday Use
The Delta 3 Plus is the light one at 12.5kg. The AC180P and the 1500 both weigh 16kg. None of them is a burden over a short carry, but the Plus is noticeably easier to lift over your tailgate.
Ports tell a similar story. The EcoFlows give you four AC outlets each, with USB-C at up to 140W on the Plus and twin 100W ports on the 1500. The AC180P has two AC outlets and a single 100W USB-C, but counters with a 15W wireless charging pad on top for your phone.
All three work as a UPS, switching to battery when the grid drops out. The 1500 quotes a switchover under 15 milliseconds, fast enough to keep your desktop alive through a blackout.
Expandability
Only the Delta 3 Plus grows. Add EcoFlow's extra batteries and it stretches from 1,024Wh to 5kWh, which turns a weekend unit into genuine home backup over time.
The AC180P and the 1500 are fixed. What you buy is what you'll have, so size them for your biggest regular trip, not your average one.
Which One Should You Buy
Most Campers and Weekenders
The AC180P. Big battery, proven reliability, wireless pad, and hundreds of dollars left in your pocket for fuel and bait. It's the best value of the three and it isn't close.
Fast Turnarounds and Home Backup
The Delta 3 Plus. A 56-minute charge means it's ready before you've finished packing the car, and the expandable battery gives it a future the others don't have.
Bigger Loads and Longer Trips
The Delta 3 1500. The biggest battery here, 3,600W of surge, and X-Boost for the kettle. Suits longer stays where recharging is rare and your demand is high.
The Verdict
On value, the AC180P wins this comparison and it's not a debate: 40% more capacity than the Delta 3 Plus for $430 less. On features, EcoFlow is ahead, with faster charging, more surge, more ports and expansion on the Plus.
