The differences that matter
- Continuous output, 1,000 vs 500 W → the BLUETTI takes on loads twice as large.
- Maximum solar input, 500 vs 220 W → the BLUETTI uses a large panel in full; the RIVER 2 Max takes 220 W of it.
- Capacity and weight, 864 Wh and 10.2 kg vs 512 Wh and 6.1 kg → more hours at the same load, for four kilos more to carry.
- Backup, UPS at 20 ms vs EPS with a pause (30 ms) → in a power cut the BLUETTI moves to battery in continuity mode, the RIVER 2 Max with a short pause.
Which one to choose
Choose BLUETTI AC70P if…
you power appliances the RIVER 2 Max does not sustain and want to recharge quickly: the maker declares 0.85 kW from the mains and 0 to 80% in 45 minutes, with a 1,500 W peak. You can also add capacity later, and operation is declared from −20 °C. The price is weight, which makes it less convenient to carry around.
Choose EcoFlow RIVER 2 Max if…
you carry it around often and lighter loads are enough; it works up to a declared 45 °C and the declared peak reaches 1,000 W. You give up output, solar input and energy, and in a power cut it moves to battery with a short pause.
