At a Glance
This comparison targets buyers choosing between two Bluetti LFP stations that share the same solar panel compatibility (19 panels, 500W max input) but sit in different weight and output classes. The AC180 delivers 1800W of running power with 2700W surge and a 1152 Wh battery, powering 39 out of 53 devices tested.
The AC70 runs at 1000W with a 2000W surge and 768 Wh of capacity, covering 24 of those same 53 devices. That gap in device coverage is significant: every device the AC70 can handle, the AC180 handles too, but 15 additional devices only run on the larger unit.
The AC180 also adds UPS functionality with a 20ms switchover and offers 3500 charge cycles versus 3000. The tradeoff is weight: at 36.2 lbs the AC180 is nearly 14 lbs heavier than the 22.5 lb AC70, which matters for camp trips and trunk space.
