The differences that matter
- Warranty 2 years vs 5, declared cycles 6000 vs 3000 → on the Elite 300 the warranty runs out first: the big cycle number does not decide anything.
- Weight 26.3 kg vs 39 kg → the Elite 400 has wheels and a handle because it needs them; the 300 is easier to lift.
- Solar input 1200 W vs 1000 W → the Elite 300 takes more panels at once.
Which one to choose
Choose BLUETTI Elite 300 if…
you carry it by hand or load it in the car: 26.3 kg against 39. It takes 1200 W of solar input, 200 W more than the Elite 400, and a USB-C port up to 140 W. You accept 0.8 kWh less and only two years of warranty.
Choose BLUETTI Elite 400 if…
you need more energy in one unit, 3.84 kWh, with five years of warranty; wheels and a handle help move it, and it works between -20 and 40 °C. That is 39 kg to move and 1000 W of solar input instead of 1200.
