Anker SOLIX C800 Plus
The C800 Plus outlived its twin, the C800, in Anker’s catalogue: the same 768 watt-hours and 1,200 watts, 24 pounds, a CPAP night on half the tank. It loses two head-to-heads in three, 12 wins in 37, to units with more tank. The few owners who wrote in own the EcoFlow too and prefer this chassis, a specific compliment.

What the SOLIX C800 Plus actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the SOLIX C800 Plus if…
You want the cheaper watt-hour today and don't need to run more than one device at a time.
Decided 11 matchups · read one →
The camper or prepper whose heaviest load is a fridge, lights, and device charging — 768Wh and 1,200W cover it, and you keep $300.
Decided 3 matchups · read one →
The camper who wants the lights: the pop-up camping-light pole is a real feature after dark, and no S2000 spec replaces it.
Decided 2 matchups · read one →
Your loads are small and you know exactly what they are. A fridge and freezer drawing 10% of the pack over eight hours [B6] is well inside 653Wh of usable energy.

A rival won when…
You want the top cubby for cords and small gear more than you want a built-in light.
Decided 10 matchups · read one →
You need genuine surge headroom for a compressor or motor start, or you want the option to add capacity later without buying a second whole unit.
Decided 2 matchups · read one →
You want one box for the outage list and no second thoughts. 1,800W continuous covers a normal household emergency list, and 870Wh of usable energy runs a 320Wh CPAP night for nearly three nights.

How to read this
- Usual is the price the unit carried most of the time, tested for how long it held rather than how often we looked. A weekend promotion cannot move it.
- Best is the lowest price we have read on the store itself. Typed coupon codes, member-only prices and marketplace listings are not counted; anything applied automatically at checkout is.
- A gap in the line is a day we could not read a price. We never draw across one, and we never show the store’s own “was” price.

Raw counts reward whoever writes most, and people write when something breaks. Here each report is weighted by what the complaint costs a buyer (a failure outranks an app gripe) and by its evidence (a measured owner report outranks a shopper’s opinion), then compared with every report in the corpus.

Fan noise is consistently reported as noticeable during fast AC charging or high sustained wattage, though most reviewers call it 'manageable' rather than a dealbreaker.

Anker, brand-wide
56% positive across 687 reports. The brand-wide complaint is durability & failures (65% negative); the brand-wide praise is capacity & runtime (84% positive).
From the test desk
“Every axis that used to require a trade-off now points the same direction.”
“Spec for spec these are the same machine: 768Wh, 1200W with a 1600W surge, 300W solar, 3,000 cycles, a 5-year warranty, ~24 lbs, and the same 58-minute fast charge.”
“Identical 768Wh capacity removes storage from the argument entirely, so the question is what you pay for everything built around that battery — and at $349 against $649 the RIVER 2 Pro is now about $300 cheaper for the…”

Questions people ask
Can the SOLIX C800 Plus be expanded later if I need more capacity?
No — it's a closed system for the life of the unit. The C1000 Gen 2 accepts Anker's expansion batteries, so it can grow past its starting 1,024Wh if your needs increase.
Is the Anker SOLIX C800 Plus just a bigger 535 PowerHouse?
Not really. It has 256Wh more capacity, but the bigger differences are a UPS switchover, an Anker app, faster solar input, and more than double the continuous output (1200W against 500W), capabilities the 535 was never built with, not just a larger battery.
Is the SOLIX C800 Plus's 45dB noise rating trustworthy?
It's Anker's own published spec, so it's a real number, but reviewers running the unit under sustained load or fast charging describe the fan as clearly audible in a quiet room [B1][B11], treat 45dB as a lab measurement, not a guarantee of how it sounds mid-charge. The 535, for comparison, has no published dB figure at all.
Is the EcoFlow RIVER 3 Max or the Anker SOLIX C800 Plus better for backpacking?
The RIVER 3 Max, decisively. At 10.4 lbs against the C800 Plus's 24, it's the only one of the two that genuinely fits a backpack, and it costs $80 less. Just know its 600W continuous output can't run higher-draw devices the C800 Plus's 1,200W can.
Is the EcoFlow DELTA 2 cheaper than the Anker SOLIX C800 Plus?
Yes. The DELTA 2 is $499 against the SOLIX C800 Plus's $649 — a $150 gap that also buys 256 more watt-hours, 600 more output watts, and an expansion path the C800 Plus doesn't have.
