A:Answer Dear customer,
The C300X can deliver a maximum of 300W through its AC outlets. It features two 140W USB-C ports: C2 supports both input and output, while C3 supports output only.
With a battery capacity of 288Wh, the C300X can power devices requiring 100W for approximately 2.3 hours. This is calculated as follows: 288Wh x 0.8 (conversion efficiency) / 100W = 2.3 hours.
For further assistance, please email us at support@anker.com. Additionally, please let me know the power requirements of your Starlink Mini Roam. Can your device be recharged via a USB-C port, or does it require an AC port? Thanks for your attention.
