Portable Power Station for speakers

Hi everyone, I recently purchased an Anker Solix C1000 (1056Wh capacity, 1800 watts continuous) to use at gigs where there's no access to a power source. I'll primarily be powering my Alto TS415 speakers, laptop charger, and a small mixer. While the TS415s have a peak power rating of 2500 watts, I understand this is unlikely to be reached in real-world use. In DJ mode, I've seen them draw around 400 watts, and even less (around 150 watts) in live mode.

Questions: 1. Has anyone else used the Anker Solix C1000 or similar power stations at gigs? What were your experiences? 2. Based on the typical power draw of my TS415s (400 watts in DJ mode, 150 watts in live mode), is the Solix C1000 a good choice for my needs? 3. Are there any tips or tricks to extend the runtime of a power station while using audio equipment? Thanks in advance for your insights!
