BLUETTI AC200MAX: Runtime & Specs

By Hicham M. · Specs from BLUETTI's published documents, as of September 2026 · How we calculate

The BLUETTI AC200MAX is a 2,048 Wh LiFePO4 power station with 2,200 W of continuous AC output and a 4,800 W surge rating. It runs a typical full-size fridge for about 30 hours. It has been replaced or discontinued, but many are still in use.

Our notes

The AC200MAX's standout spec is its solar input. It accepts 10 to 145 V, far wider than the 60 V cap on most 2 kWh models, so you can wire several panels in series and run longer cables with less loss, up to 900 W. It also has a TT-30 outlet for RV use and expands to 8,192 Wh with two B300 batteries.

Its weak spot is wall charging. The standard adapter supplies 500 W, about 5.5 to 6 hours for a full charge, or 1,000 W with a second adapter. BLUETTI's replacement, the Elite 200 V2, charges at 1,800 W (full in about 1.4 hours), adds a 15 ms UPS mode and is lighter (53.4 lb against 61.9 lb), but it can't be expanded.

BLUETTI lists no UPS switchover for the AC200MAX. A fridge runs about 30 hours on the main battery, and about five days with both expansion batteries. It's at its best in an RV or a cabin with a good panel array. If you'll mostly top it up from a wall outlet before a storm, that 500 W charger gets old fast.

Simulated runtimes (not measured)

Nobody tested this unit for this page. These figures come from a computer simulation of the AC200MAX, and they are estimates. The plain runtime table below divides energy by average draw at 85% efficiency. The simulation also charges the battery for the power the inverter burns just by being switched on, which is why small loads come out shorter. Where we have measured a unit, the measurement is shown separately and labeled as measured.

Simulated runtimes for the BLUETTI AC200MAX
Device	Spec-sheet math	Simulated, typical	Likely range	Simulated at 0 °C
Wi-Fi router + modem	4.8 days	2.2 days	42 hours to 2.7 days	43 hours
CPAP (no humidifier)	2.4 days	36 hours	32 hours to 42 hours	30 hours
Starlink Standard	19 hours	16 hours	15 hours to 18 hours	14 hours
Refrigerator (full-size, ENERGY STAR)	30 hours	23 hours	21 hours to 26 hours	20 hours

Nonstop runtime from full to battery cutoff. Likely range = middle 80% of 200 simulated runs with the uncertain inputs varied. The inverter idle draw is assumed, not published: we assumed about 21 W for this model, varied from 13 to 32 W. If the real figure is lower, real runtimes land closer to the spec-sheet column.

How this was simulated

The battery is stepped down every 2 minutes until it reaches cutoff, for 200 runs per device. Results are seeded, so the page shows the same numbers on every build.
Battery draw = load + inverter idle draw + 4–8% of the load + a loss that rises with load squared (4% at full output).
Usable capacity = 92–98% of rated Wh, for protection cutoff and aging.
At 0 °C, 80–90% of that capacity is assumed available.
Fridges cycle on and off every 30–50 minutes at the share of the time set by their average draw. The inverter idle draw continues while the compressor is off.
Devices that exceed this model's output or surge rating are left out. Loads are US 120 V devices.

Questions

How long will the BLUETTI AC200MAX run a refrigerator?

About 30 hours for a typical ENERGY STAR full-size fridge averaging 58 W, assuming 85% inverter efficiency. Older or larger fridges use more. Try your own numbers.

Can the BLUETTI AC200MAX run a microwave?

Yes. A typical 1,000 W microwave pulls about 1,500 W from the outlet, within its 2,200 W continuous output. A full battery gives about 1.2 hours of cooking.

How many amp-hours is the BLUETTI AC200MAX?

The BLUETTI AC200MAX works out to about 171 Ah at 12 V, or 160 Ah at 12.8 V, the nominal voltage of a 12 V LiFePO4 battery. Both are our conversion of BLUETTI's 2,048 Wh rating: amp-hours = watt-hours ÷ volts. The battery inside may run at a different voltage, so an amp-hour figure in a manual or on a product listing can look very different for the same energy. For scale, a 12 V 100 Ah LiFePO4 battery holds 1,280 Wh, so this model holds about as much as 1.6 of them. How we convert amp-hours.

How long does the BLUETTI AC200MAX take to charge?

BLUETTI's published charging claim: “≈5.5–6 h (500W adapter)”. Max AC charging power is 500 W. With solar, it accepts up to 900 W. With 900 W of panels that's roughly 3 hours of good sun from empty.

Is the BLUETTI AC200MAX expandable?

Yes, up to 8,192 Wh with BLUETTI's extra batteries.
