Our verdict

The best USB-C hub here — but the Elite 30 V2 is better value for AC loads.

288 Wh, three AC outlets and two 140 W two-way USB-C ports in a tall, compact 9 lb body. It's whisper-quiet at 25 dB and backed by a 5-year warranty, but costs more than rivals with twice the output.

Ideal for

Laptop-heavy travel, a quiet bedside CPAP (no heat) and desk UPS duty.

Skip it if

Anything that draws more than 300 W.

In-depth review

What it's like to own

The C300 is built for laptops and gadgets: two 140 W USB-C ports (PD 3.1) can fast-charge big laptops or recharge the station itself, and three AC outlets share 300 W.

It reaches 80% in 50 minutes from the wall and doubles as a 10 ms UPS. Fan noise is rated at 25 dB, among the quietest here, which matters for a bedside CPAP.

Owners call it neat and well built, and several use it as a desk UPS. At $330 it's pricier than the Elite 30 V2, which has twice the AC output.

Pros

  • Two 140 W two-way USB-C ports
  • 25 dB quiet
  • 10 ms UPS
  • 5-year warranty

Cons

  • Only 300 W AC
  • 100 W max solar
  • Pricier than the Elite 30 V2
