Specifications checked against manufacturer pages on 2026-08-23.
The Bluetti AC180 (1,152 Wh, 1,800 W) and the Bluetti AC180P (1,440 Wh, 1,800 W), compared on the figures their makers publish. Bluetti changed 3 published figures between them — rated capacity, weight, manufacturer list price when checked — and states 2 more only for one of the two.
In short. The AC180 leads on cost per watt-hour ($0.43/Wh vs $0.45/Wh) and continuous watts per dollar (3.61 W/$ vs 2.77 W/$). The AC180P leads on watt-hours per pound (40.8 Wh/lb vs 32.6 Wh/lb). 3 of 6 measures tie or are not comparable. Note: the AC180P is listed as discontinued at the manufacturer; the price used here is its last list price.

Notes on the figures
- AC180, rated capacity: 1,152Wh (AC180) / 1,440Wh (AC180P)
- AC180P, rated capacity: From Tech Specs > BATTERY INFO. Headline bullet also says “1,440Wh Larger Capacity*”; comparison table column for AC180P says 1440Wh.
- AC180, continuous output: 4 x 120V/15A 1800W In Total
- AC180P, continuous output: From Tech Specs > OUTPUT. Headline bullet: “1,800W AC Output / 2,700W Power Lifting Mode”. Discharging temperature line adds a derate: 86°F-104°F: 1,500W Max.
- AC180, surge: The spec table labels this “Surge Power”, but the same 2,700 W figure is Bluetti’s Power Lifting Mode for resistive heating loads (FAQ Q1: “AC180 can run high-power heating devices up to 2,700W … Do NOT use this unit to run an air conditioner or washing machine.”). Treat as a boost mode for resistive loads; it is not a conventional motor-start surge rating and should not be read as one.
- AC180P, surge: The spec table labels this “Surge Power”, but the same 2,700W figure is marketed as “Power Lifting Mode” for resistive heating loads (FAQ Q1: “AC180P can run high-power heating devices up to 2,700W … Do NOT use this unit to run an air conditioner or washing machine.”). Treat as a boost mode for resistive loads, not a conventional motor-start surge rating.
- AC180, recharge: Bluetti publishes a 0–80% time (45 minutes), not a full-charge time.
- AC180P, full recharge: Upper bound of the stated full-charge range (≈1.3-1.8 hours = ≈78-108 min) in Turbo Charging mode (1,440W, enabled via the BLUETTI App). FAQ Q5 on the same page gives a different range: “you can fill it up in only 1.5-2 hours”. The 0-80% figure is stated separately: “0-80% Recharging in 45Mins with 1,440W AC Input”. Standard mode (around 1,000W) is 1.7-2.2 hrs; Silent mode (260W) 4.9-5.4 hrs per FAQ Q6.
- AC180, cell chemistry: LiFePO₄ (Lithium Iron Phosphate)
- AC180P, cell chemistry: From Tech Specs > BATTERY INFO.
- AC180, cycle life: 3,500+ Cycles to 80% Original Capacity
- AC180P, cycle life: Stated as “3,500+”, i.e. a minimum; 3,500 is the floor.
- AC180P, cycle life: Life Cycles: 3,500+ Cycles to 80% Original Capacity
- AC180, expandable: Bluetti’s B-series batteries can charge the AC180 but do not extend its capacity as a single system.
- AC180P, expandable: FAQ Q13. The marketing paragraph “Get your AC180P charged via expansion batteries – B80 (806Wh), B230 (2048Wh), and B300 (3072Wh) – to ensure a continuous power source of up to 4,224Wh” describes using those batteries as a charging source, not a combined expandable system.
- AC180, solar input: Solar Input: 500W Max., VOC 12-60VDC, 10A
- AC180P, solar input: From Tech Specs > INPUT. FAQ Q8 repeats: Total open circuit voltage 12-60V, Max. input power 500W, MC4 connectors.
- AC180, AC input: Turbo Mode figure from SPECS > INPUT.
- AC180P, AC input: Turbo Mode figure (Tech Specs > INPUT; also “Max Input: 1,440W”). Standard Mode is “1000W Max.”; Turbo is switched on in the BLUETTI App per FAQ Q5.
- AC180, AC outlets: From SPECS > OUTPUT.
- AC180P, AC outlets: From Tech Specs > OUTPUT. Comparison table: “4x120V(1800W Total)”.
- AC180, USB-C: From SPECS > OUTPUT.
- AC180P, USB-C: Single USB-C port. Other ports: 4 x USB-A (two pairs at 15W in total each), 1 x 12V/10A car outlet, 1 x 15W wireless charging pad.
- AC180, app: Bluetooth only; the page does not claim Wi-Fi.
- AC180P, app: Bluetooth only; comparison table lists “BLUETTI App (Bluetooth)”. The page does not claim Wi-Fi.
- AC180P, noise: FAQ Q6. Applies only to the Silent (260W) charging mode; the manufacturer states no noise figure for normal operation or Turbo charging.
- AC180, warranty: From SPECS > GENERAL.
- AC180P, warranty: From Tech Specs > GENERAL; page header also says “5-year Hassle Free Warranty”.
- AC180, weight: Bluetti’s page gives 35.3 lb in the spec table and 37 lb in the description; we use the spec table.
- AC180P, weight: From Tech Specs > GENERAL. The comparison table rounds this to “35.3 lbs”; the description says “weighs about 35.27lbs/16kg”.
- AC180, price: Manufacturer price when checked; no separate list price was shown.
- AC180P, price: Manufacturer price for the base variant “AC180P | 1800W,1440Wh,Power Station”. All variants were marked ” – sold out – ” at check time. Bundle prices: AC180P+200W Solar US$899.00; AC180P+350W Solar US$1,199.00; AC180P+Charger 1 US$799.00.
The same specs, normalized
Ratios, so the bigger unit does not win by default.
| Measure | AC180 | AC180P |
|---|---|---|
| Cost per watt-hour | $0.43/Wh ✓ | $0.45/Wh |
| Watt-hours per pound | 32.6 Wh/lb | 40.8 Wh/lb ✓ |
| Surge headroom | Not comparable — the AC180 figure is a boost-mode rating, not a motor-start surge. | |
| Recharge rate | Not comparable — Bluetti does not state a full-recharge time for the AC180. | |
| Rated cycle life | 3,500 | 3,500 |
| Continuous watts per dollar | 3.61 W/$ ✓ | 2.77 W/$ |
Definitions and direction of each ratio: How we verify. A recharge rate marked ≥ is computed from an upper-bound recharge time, so the true rate is at least that figure; no check mark on that row.

Calculated, not measured: hours = rated Wh × efficiency ÷ (appliance W × duty); assumptions on How we verify. “Unlikely to start”: start-up surge exceeds the stated surge rating. “Start-up not assessed” appears where the start-up draw meets or exceeds the unit’s continuous rating and the unit states no conventional motor-start surge to check it against (AC180 and AC180P); the hours assume the motor starts.
What the AC180P changes
Of the 16 published specifications we compare, Bluetti changed 3 (AC180 → AC180P); 11 are the same on paper.
- Rated capacity: 1,152 Wh → 1,440 Wh
- Weight: 35.3 lb → 35.27 lb
- Manufacturer list price when checked: $499 → $649
Bluetti states 2 more only for one of the two: Full recharge from wall (Manufacturer does not state (0–80% in 45 min) → 78–108 min); Stated noise (Manufacturer does not state → 45 dB).
Not listed as changes: surge output (the two figures are not measured on the same basis; see the notes).
What the differences mean
Price per watt-hour. At the list prices we checked, the AC180 costs $0.43/Wh against $0.45/Wh for the AC180P. At list the AC180 is $150 cheaper ($499 vs $649) for 1,152 Wh vs 1,440 Wh. Prices move with sales; the ratio moves with them. Note: the AC180P is listed as discontinued at the manufacturer; its figure here is the last list price shown.
Weight for the capacity. The AC180P carries 40.8 Wh/lb against 32.6 Wh/lb for the AC180. Both are two-hands-and-a-flat-surface units; the difference matters if the unit moves between car, porch and basement.
Output for the money. 3.61 W/$ on the AC180 against 2.77 W/$ on the AC180P: this is the ratio to read if your outage plan is one big appliance, not many small ones.
Which one, and for whom
On normalized measures the AC180 leads on cost per watt-hour ($0.43/Wh vs $0.45/Wh) and continuous watts per dollar (3.61 W/$ vs 2.77 W/$). The AC180P answers on watt-hours per pound (40.8 Wh/lb vs 32.6 Wh/lb). The deciding figure is the one your own outage will test first:
- CPAP overnight. Switchover: AC180 no UPS figure stated, AC180P no UPS figure stated. A 40 W CPAP runs roughly 20–24 hr on the AC180 and 25–30 hr on the AC180P. Both run the night; neither maker states a switchover time, so published numbers cannot separate them for CPAP use.
- Keeping a refrigerator cold. The compressor has to start before hours matter. The AC180 states a boost figure rather than a motor-start surge rating; the AC180P states a boost figure rather than a motor-start surge rating. A full-size refrigerator needs about 900 W to start.
- A multi-day outage with a generator or solar to recharge from. Full recharge: AC180 0–80% in 45 min (no full-charge time stated), AC180P a stated 78–108 min range. These are not comparable: Bluetti states no full-charge time for the AC180.

A 1,152–1,440 Wh battery cannot do what a gasoline generator does — the runtime table shows a 1,500 W space heater emptying either unit in 0.6–0.8 hr — but it also cannot poison a household. How often gasoline generators kill indoors — and how the official count keeps being revised — is documented in our CPSC revision matrix, and this page puts every verified unit on the same refrigerator scenario.
