SOLIX C800 Plus vs Yeti 1500X

This comparison targets buyers weighing a compact, long-cycle portable unit against a higher-output home-backup station. The Yeti 1500X delivers 2000W of running power and 3500W surge, nearly double the C800 Plus's 1200W/1600W output. That extra headroom lets the Yeti power 43 of the 53 devices tested here, while the C800 Plus handles only 24.

Battery capacity tells a similar story: 1516 Wh versus 768 Wh, giving the Goal Zero unit roughly twice the stored energy and expandable capacity on top. Solar input peaks at 600W on the Yeti versus 300W on the Anker, though the C800 Plus recharges faster at 3.7 hours thanks to its smaller battery. The tradeoff is weight and longevity.

At 24 lbs with LFP chemistry rated for 3000 cycles, the Anker is far easier to carry and will last years longer before capacity degrades. The Yeti's NMC cells are rated at just 500 cycles, and the unit weighs 45.6 lbs.

The C800 Plus suits buyers who prioritize portability and long-term battery life over raw output, especially for light camping or small-device charging where 1200W is enough. The Yeti 1500X is the better fit for home backup, higher-draw appliances, and anyone who needs broad device coverage across a household. With a compatibility score of 82.5 versus 48.5 and nearly twice the capacity and power, the Yeti 1500X is the clear winner of this matchup.
