BLUETTI AC180P vs BLUETTI AC180
BLUETTI AC180P
BLUETTI AC180The AC180P holds 25% more energy, and that is the gap worth deciding on: it runs longer between charges. They are level on AC output, weight and rated cycle life. Scored across this catalogue they land at 6.9 and 6.5 out of 10.

The rows worth your attention are the ones where the gap is large enough to change a decision. On this pair that means capacity. Everything else is close enough to ignore.
Where they really separate: capacity
This is the one gap large enough to decide the question. The AC180P comes out 25% ahead on capacity, and the reason that matters is practical rather than arithmetic.
Capacity sets how long a unit runs something, not what it can run. A larger pack behind the same inverter buys hours, not new appliances.
What each one will run
Same arithmetic for both: usable watt hours after an assumed 85% inverter efficiency, divided by average draw rather than peak.

Common questions
Is the AC180P or the AC180 better value?
This site does not print prices, because a stale price is worse than none. Check both on Amazon, then weigh the gap against the differences above. A 25% lead on capacity is worth paying for only if that axis matters to your use.
Can I compare their surge ratings directly?
Not always. BLUETTI's Lifting Power and EcoFlow's X-Boost run appliances above rated output by lowering voltage, which suits a kettle or a heater but not a motor or a computer. A conventional surge rating means something else: a brief tolerance for start-up current. The table keeps each maker's own label attached.
Is the newer one simply a better version?
Not automatically. Makers revise units to hit a different price or size, and a newer model sometimes drops something the older one had. Read the table rather than the generation number.
