Very little. Both are 2,048Wh LiFePO4 stations with the same 2,400W output, 4,000W peak, 30-amp TT-30 RV outlet, charging, expansion, size and weight. The difference is the outlet layout: on our listings, the C2000 Gen 2 has five household AC outlets plus the TT-30R, and the C2000X Gen 2 has four plus the TT-30. They carry different Anker model numbers, A1783 for the C2000 Gen 2 and A1785 for the C2000X Gen 2.

Which to buy
Buy whichever is in stock or better priced on the day. If you will plug in a lot of household devices at once, the C2000 Gen 2's extra outlet is a small convenience. Everything that matters for an RV, including the TT-30 outlet, the solar input, the alternator-charging option and the BP2000 expansion battery, is the same on both.
