The differences that matter
- Solar input 500 vs 220 W → the first accepts an array of panels more than twice as large.
- 1000 vs 800 W continuous → 200 W more headroom on what runs together.
- 10.2 vs 7.8 kg → 2.4 kg more to carry with the first.
- UPS in 20 ms vs EPS in 30 ms → when the mains drops, the first switches to battery faster.
Which one to choose
Choose BLUETTI AC70P if…
you charge from panels and want an input of up to 500 W, with loads up to 1000 W, UPS mode (20 ms declared) and the option to expand it. You carry 10.2 kg instead of 7.8.
Choose EcoFlow RIVER 2 Pro if…
you move it often and 800 W continuous with a 1600 W peak is enough: 7.8 kg and maximum charging of 0.94 kW. You accept at most 220 W of solar and a 30 ms gap when switching to battery (EPS).
