BLUETTI AC models compared

What the AC series units we track show

Computed from the sourced specifications of the models in our catalogue — a deliberately selected slice of what this brand sells, never the full lineup.

The five AC units in this published family comparison run 448 Wh to 2,048 Wh, and four of the five carry a sourced expansion capability — the AC50B is the exception, and it is also the only one in the family with no sourced surge figure at all, which is a real gap on a unit small enough that surge is what decides its limits. The AC70 is the one worth a second look: at 768 Wh and 10.2 kg it scores 71.1, the highest of these five and, by a tenth of a point, the highest of any Bluetti unit we track — the 2,764.8 Wh Apex 300 sits just behind it at 71.0. Treat that gap as a tie rather than a verdict; what it really says is that the AC70 buys its place with output and charging rather than capacity, and that the Apex 300 is scored as the bare unit, without the optional Hub D1 that carries its 12 V and Anderson ports.
