Quick answers
- Is the Anker SOLIX C800 X better than the Goal Zero Yeti 700 6th gen (LiFePO4)?
- Anker SOLIX C800 X leads by 24 points overall.
- Which has more usable capacity, the Anker SOLIX C800 X or Goal Zero Yeti 700 6th gen (LiFePO4)?
- Neither, in any way you would notice: 580 Wh against 575 Wh is a 0.9% gap, which is smaller than the swing you get from running the same load on a cold morning. Treat them as the same size and decide on output, weight, or today's price instead. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices.
- Which has more AC output, the Anker SOLIX C800 X or Goal Zero Yeti 700 6th gen (LiFePO4)?
- The Anker SOLIX C800 X: 1,200 W versus 600 W continuous. That gap matters only if a load sits between the two numbers — below 600 W both run it, above 1,200 W neither does. Surge headroom follows the same order: 1,600 W against 1,000 W, and surge is what decides whether a compressor or pump actually starts.
- How does runtime compare between the Anker SOLIX C800 X and Goal Zero Yeti 700 6th gen (LiFePO4)?
- They run within 0.9% of each other on the same load — about 9.2 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
- Which is lighter, the Anker SOLIX C800 X or Goal Zero Yeti 700 6th gen (LiFePO4)?
- The Goal Zero Yeti 700 6th gen (LiFePO4), by 1.7 kg (9.2 kg versus 10.9 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
- Which recharges faster from the wall, the Anker SOLIX C800 X or Goal Zero Yeti 700 6th gen (LiFePO4)?
- The Anker SOLIX C800 X: 58 minutes from empty to full against 102 minutes, a difference of 44 minutes. This matters most between outages and during a short grid window — if you only ever recharge overnight, it does not matter at all.
- Which model should I buy for my use case?
- On the sub-scores that describe each use case: the Anker SOLIX C800 X for home backup; the Goal Zero Yeti 700 6th gen (LiFePO4) for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
