At a Glance
This comparison targets buyers deciding between a high-capacity home backup unit and a lighter, more portable alternative from the same brand. The AC200MAX delivers 2200W of running power with a 2048 Wh battery, powering 45 out of 53 tested devices. The AC70 manages 1000W and 768 Wh, covering 24 of those same 53 devices.
That gap in device compatibility is significant: the AC200MAX scored 88.5 versus the AC70's 46.5 in our testing. Expansion capability further separates these two, since only the AC200MAX supports add-on batteries. Solar input also favors the larger unit at 900W max versus 500W on the AC70.
The tradeoff is weight and portability. At 22.5 lbs, the AC70 is roughly a third the weight of the 61.9 lb AC200MAX, making it far easier to grab for camping, tailgating, or day trips.
