Bluetti AC180 vs EcoFlow Delta 2
Two of the most cross-shopped 1000Wh-class LiFePO4 units, and a genuinely close call. The AC180 wins on capacity and is often the cheaper box, which makes it a strong value pick. The Delta 2 wins on recharge speed, ports, and the option to add more capacity later. Which one fits comes down to whether you want the best deal for occasional use or a unit that grows with you.

Where each one wins
AC180 wins on value and capacity
The Bluetti AC180 gives you more energy in the box at 1152Wh and usually does it for less money. It runs the same 1800W continuous output as the Delta 2, so it handles a microwave, coffee maker, or power tool just as confidently. For the person who wants a dependable backup battery for camping and occasional outages, and does not need fast recharging or expansion, it is the smarter spend.
Delta 2 wins on speed and growth
The EcoFlow Delta 2 charges from empty to 80 percent in about 50 minutes, gives you six AC outlets, and accepts a smart extra battery to roughly double its capacity to 2048Wh. The Wi-Fi app and faster recharge make it the better fit for van life and daily cycling, where you top up often and may want more capacity later. It is the more flexible long-term platform.
Which should you buy?
For value and occasional use, buy the Bluetti AC180. You get more capacity than the Delta 2 and usually pay less for it, with the same strong 1800W output. If the unit will spend most of its life on standby and come out for trips and outages, the AC180 gives you the most battery for your money.
For van life and expandable backup, buy the EcoFlow Delta 2. The far faster recharge, extra outlets, Wi-Fi app, and the clean path to add a second battery make it the better choice when you cycle it daily or expect your needs to grow. Both are LiFePO4, so longevity is not the deciding factor here. The split is value versus flexibility.

Frequently Asked Questions
Which holds more energy, the Bluetti AC180 or the EcoFlow Delta 2?
The Bluetti AC180, by a small margin. It carries about 1152Wh against the Delta 2's 1024Wh, so it has a little more runtime in the tank before it needs a recharge. In real use that gap is around 12 percent, which buys you maybe an extra hour or two on a fridge. It is a tiebreaker, not a headline reason to choose one box over the other, since both sit firmly in the same 1000Wh class.
Which charges faster from the wall?
The EcoFlow Delta 2, clearly. It reaches 80 percent in about 50 minutes and a full charge in roughly 80 minutes, while the Bluetti AC180 takes closer to 1.5 hours for a full top-up. In an outage that speed matters, because the Delta 2 can grab a fast charge during a brief grid window or off a generator and get back to standby quickly. If you expect to recharge often and want minimal downtime, the Delta 2 has the edge here.
Which takes more solar input?
The EcoFlow Delta 2, at up to 500W of solar against the Bluetti AC180's 500W ceiling as well, but the Delta 2's MPPT tends to start harvesting sooner in low light. Both will refill from panels in similar time under full sun, roughly 3 to 4 hours with enough watts on the array. The practical difference is small here, so solar charging is not the deciding factor between these two. Match your panel wattage to whichever unit you buy and either will keep up.
Can either one be expanded with more capacity?
The EcoFlow Delta 2 can, and it is one of the main reasons to pick it. It accepts a 1024Wh smart extra battery that roughly doubles capacity to about 2048Wh, and the platform supports growth toward around 3kWh. The Bluetti AC180 is a sealed unit with no expansion port, so what you buy is what you have for its whole life. If you think your needs might grow, the Delta 2's clean expansion path is worth real money.
Are both safe to run a CPAP or fridge overnight?
Yes. Both are around the 1000Wh class with pure sine wave output, which is plenty to run a typical CPAP through the night with capacity to spare, and enough to keep an efficient 12V fridge cold for a day or more. Turn off any CPAP humidifier heat to stretch runtime, since that heater is the single biggest draw on the machine. For a fridge, both units will idle quietly between compressor cycles and last well past a single night.
