How we assign awards →The differences that matter
- 300 W vs 600 W continuous, 600 W vs 1500 W peak → the first handles a few small devices; the second takes more at once and has room for heavier start-up loads.
- Solar input 100 W vs 200 W → the second can be paired with a panel twice the size, so charging from the sun is quicker.
- 25 dB vs 30 dB → the first is the quieter one, which matters if the battery sits near someone sleeping or working.
Which one to choose
Choose Anker SOLIX C300 if…
you keep it next to you, at night or where people work, and run only a few small loads: it is rated at 25 dB. You accept 300 W continuous with a 600 W peak and a solar input of at most 100 W, so charging from a panel is slower.
Choose BLUETTI Elite 30 V2 if…
you need to plug in something above 300 W, up to 600 W continuous with a 1500 W peak, or charge from panels of up to 200 W. You settle for a declared 30 dB instead of 25.
