The verdict
Buy the AC200LCheck price at BLUETTI. It costs less per watt-hour ($0.44 against $0.59), and carries 200W more.
The AC200MAX Expandable is the buy only if you find it materially cheaper than the price below. Full working underneath.

The short answer
Both hold 2,048Wh, so this decision is not about capacity at all. The BLUETTI AC200L is the cheaper way to buy a watt-hour, at $0.44 against $0.59. The BLUETTI AC200L carries 200W more continuous load, which is what decides whether the heavier kitchen appliances start at all. The BLUETTI AC200MAX Expandable is rated for more cycles, 3,500 against 3,000, which is a longevity difference rather than a performance one.

A dot marks the better figure on that row. An em dash means the manufacturer does not publish it, and we would rather leave the cell empty than fill it with a number we cannot source.
What each one will run
| Load | AC200MAX Expandable | AC200L |
|---|---|---|
| Wi-Fi router (10W) | 174 hr | 174 hr |
| CPAP, humidifier off (40W) | 44 hr | 44 hr |
| 12V portable fridge (45W avg) | 39 hr | 39 hr |
| Full-size fridge (50W avg) | 35 hr | 35 hr |
| Laptop (60W) | 29 hr | 29 hr |
| 55-inch TV (90W) | 19 hr 21 min | 19 hr 21 min |
| Microwave (1,000W) | 1 hr 44 min | 1 hr 44 min |
Figures are capacity divided by draw, with 15% taken off for inverter losses on AC loads. They are arithmetic rather than bench measurements, and a cold battery or a compressor cycling hard will come in lower. Where a row says the unit will not run a load, that load exceeds what its inverter carries continuously.
Where the AC200MAX Expandable wins
- Rated for 3,500 cycles against 3,000, so it should outlast the other by years of daily use.
- Lighter by 0.5 lb.
Where the AC200L wins
- Carries 200W more continuous load, so it starts appliances the other one refuses.
- $300 cheaper at list.
- Cheaper per watt-hour, at $0.44 against $0.59.
- Takes 300W more solar, which shortens a day of off-grid recharging.
- Recharges from the wall at 2,400W against 500W.
Which to buy
- Buy the AC200L if you are simply buying stored energy at the lowest price and the rest of the spec sheet is close enough not to matter.
- Buy the AC200L if anything on your list has a heating element or a compressor. Output, not capacity, is what decides whether it starts.
AC200MAX Expandable vs AC200L questions
Which has more capacity, the AC200MAX Expandable or the AC200L?
Neither. Both are rated at 2,048Wh, so capacity is not the deciding factor between them.
How long will each one run a fridge?
On a full-size fridge averaging 50W, the AC200MAX Expandable works out at roughly 35 hr and the AC200L at roughly 35 hr. Both assume 85% of rated capacity reaches the load, and a fridge cycling harder in a warm room will pull both numbers down.
Which is better value?
Per watt-hour stored, the AC200L at $0.44 against $0.59. That is the honest measure here, because it is the one figure that puts a price difference and a capacity difference on the same scale.
Which will last longer?
On the published cycle ratings, the AC200MAX Expandable. It is rated for 3,500 charge cycles against 3,000. At one full cycle a day that is roughly 10 years against 8 before the cells reach their rated end of life.
How we compare these
Both columns are the manufacturers’ own published figures, taken from the same catalogue of 458 products we track, and every derived number on this page, cost per watt-hour and estimated runtime, is calculated the same way for every product on the site. We do not publish a star rating for either unit, because we have not bench-tested them and a score we invented would be worth nothing to you. What we can do honestly is put the published figures side by side, do the arithmetic in public, and say plainly where a manufacturer has not published something.
