Bluetti’s AC200P is the AC180’s bigger sibling. At 2000Wh capacity and 2,000W output, the AC200P has more energy and power under the hood. Both use long-life LFP batteries (~3500 cycles) and sturdy inverters, but there are trade-offs. The AC200P delivers about 750Wh more battery (2kWh vs 1.152kWh) and can handle slightly higher loads, but it’s also much heavier (~60.6 lbs vs ~35 lbs) and more expensive (around $1,199 vs ~$1,099). It also has 6 AC outlets (vs 4 on the AC180).
One big practical difference is charging. The AC180 can top up very quickly (1440W AC input), but the AC200P has a 400W built-in charger (you must use an external AC adapter) and 700W solar input (1100W combined) – so it charges more slowly on wall power. In test, the AC200P took ~2 hours to refill its 2kWh battery with full power + solar.
In use, if you need every watt (e.g. running an RV AC for longer), the extra capacity of AC200P helps. It ran a 9,200 BTU air conditioner (~1,100W draw) for about 2 hours, whereas the AC180 would run out sooner. But for lighter duty, the AC180 offers faster recharge and easier handling. In short: go with AC200P if you want max backup (and don’t mind the weight/price); choose AC180 if you want a lighter, faster-charging unit for general camping or smaller backup needs. Both have top-notch LFP batteries, but one is just bigger.
