Our Verdict: Anker SOLIX C300 Power Station
A very light 288Wh station whose real usable capacity almost matches its rating, ideal for packing but limited to small loads.
At about 8.3 lb it is one of the lightest 288Wh LiFePO4 units, with an unusually honest near full usable capacity and whisper quiet running.
What's the bottom line?
Measured about 25 dB at 3.3 ft, quiet as a whisper, and about 28 dB under a 250W load.
Reviewers report zero vibration and no meaningful fan noise in normal use.
It is light enough that I actually take it hiking, and I love that the usable capacity really is close to the 288 on the box. Just do not expect it to run anything bigger than a laptop.

What Other Solar Generators Should You Consider?
Not sold on this one? A few others from our testing are worth a look.
The Bluetti Elite 30 V2 Power Station is our best small solar generator. A small 288Wh unit with a 600W inverter, quiet running, and a fast 10ms UPS, a good budget backup for routers and light gear.
The EcoFlow River 3 Plus Power Station is our best portable solar generator. A small 286Wh unit that is genuinely quiet with a fast UPS and snap on expansion, but its low output keeps it in device and small load territory.
The Bluetti AC70 Power Station is our best solar generator for cpap. A quiet, affordable 768Wh unit that is a natural CPAP companion, so long as you budget for real usable energy under the rated figure.
