Anker SOLIX C300 vs BLUETTI Premium 30 V2
Technical comparison · Ultraportable
Anker SOLIX C300 and BLUETTI Premium 30 V2 are two small stations with the same LFP chemistry and almost the same capacity (about 0.3 kWh), both with declared continuous backup (UPS) and a five-year warranty. What separates them is the power they sustain, and with it what you can plug in. Figures are manufacturer-declared.

The differences that matter
- Continuous output 300 W vs 600 W → above 300 W of load you need the BLUETTI, which also declares a 1500 W peak against the Anker's 600 W.
- Solar input 100 W vs 200 W → with a portable panel the BLUETTI recharges from the sun faster.
- Outputs: the BLUETTI declares a mains socket, two USB-A and two 12 V → it powers mains and 12 V devices directly.
Which one to choose
Choose Anker SOLIX C300 if…
you charge a phone and laptop over USB-C and keep a router on through a short outage, with a 4.13 kg unit that declares 25 dB. The trade-off: power stays low, and panel charging is slower.
Choose BLUETTI Premium 30 V2 if…
you plug in mains or 12 V devices, not just phones and laptops, and want headroom for peaks. It also declares a 95% depth of discharge and a 4.5 W idle draw, worth counting if you leave it switched on. The trade-off: 4.3 kg to carry, and the idle draw.
