At a Glance
This comparison targets buyers choosing between two 1800W portable power stations with similar device coverage but meaningfully different longevity and expansion paths. The DELTA (Gen 1) from EcoFlow edges ahead on raw capability: it packs 1260 Wh of capacity versus the C1000's 1056 Wh, and its 3300W surge rating outclasses the Anker unit's 2400W, giving it a better chance of starting high-draw motors and compressors.
In device compatibility testing across 53 products, the DELTA powered 40 while the C1000 managed 38. The tradeoff is lifespan and flexibility.
Anker's LFP battery is rated for 3000 cycles, nearly four times the DELTA's 800-cycle NMC cell, and the C1000 supports battery expansion and a 20ms UPS transfer for home backup use. Faster solar charging at up to 600W input also favors the Anker, cutting a full solar recharge to roughly 3.8 hours compared to 4.5 hours for the DELTA.

The Bottom Line
Pick the SOLIX C1000 if long cycle life, expandable storage, and UPS functionality matter most, especially for semi-permanent home backup or off-grid solar setups where the 3000-cycle LFP battery and 600W solar input pay dividends over years of use. Choose the DELTA (Gen 1) if you need higher surge power and greater out-of-the-box capacity for demanding appliances and can accept a shorter battery lifespan. With a compatibility score of 75.5 versus 72 and stronger surge handling, the DELTA takes the overall win for buyers prioritizing immediate power coverage.
