Anker SOLIX C300
The SOLIX C300 is nine pounds and 300 watts: a laptop all day, a fridge declined on principle. It finishes an afternoon off-grid on under half the tank and nothing longer. Fourteen owner reports run above the corpus norm, several from ex-EB3A owners; one went back after the case hit 52 degrees on the charger.

What the SOLIX C300 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.

03 · From the verdicts
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 C300 if…
You want the quieter unit (25dB) and don't mind $31 more or a slightly heavier bag.

You want a desk that rides through outages. The ≤10ms UPS keeps a router or a desktop alive through a grid blip; the 535 has no UPS to offer.

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.

67% positive weighted · corpus 51% · above the norm
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.

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
“The batteries are twins: 288Wh each, both rated for 3,000 cycles, so runtime and lifespan are settled before you compare anything else.”
“Default to the SOLIX C300.”
“Strip away the shared 288Wh cell, the shared 3,000-cycle/5-year warranty, and the identical 10ms UPS switchover, and what's left is BLUETTI charging $30.99 less for an inverter that does twice the C300's work: 600W…”

Questions people ask
Is the Anker SOLIX C300 better than the Jackery Explorer 300D?
For many buyers, yes — but it's now the pricier pick. They share the same 288Wh battery and 3,000-cycle life, and the C300 adds two more AC outlets, pushes 140W from USB-C against the Jackery's 100W, carries a five-year warranty against three, and runs quieter at 25 dB versus 45. What flipped is price: the C300 now costs about $91 more, so the 300D's edges are that it's under a pound lighter and the cheaper of the two.
Is the SOLIX C300 worth $160 more than the C200 DC?
Only if you need what that $160 buys: an AC section with three outlets and 300W of output, 600W of surge headroom, a 10-millisecond UPS switchover, more capacity, and two extra years of warranty. If your gear is all USB-C or USB-A, none of that premium does anything for you, and the C200 DC is both the cheaper purchase and the cheaper unit to own.
Is the SOLIX C300 in this comparison the same as the SOLIX C300 DC?
No, and the naming here is genuinely confusing. This comparison covers the standard SOLIX C300, which includes AC outlets. Anker also sells a separate C300 DC variant that drops AC output the same way the C200 DC does. If a listing you're looking at shows a C300 with no AC outlets, you're likely looking at that different SKU.
What's the real difference between the Anker SOLIX C300 and BLUETTI Elite 30 V2?
Both hold 288Wh on an identical 3,000-cycle, 5-year warranty, but the Elite 30 V2 runs a 600W continuous inverter with a 1,500W surge against the C300's 300W and 600W. The Elite 30 also costs $30.99 less. The C300 counters with dual 140W USB-C ports against the Elite 30's single 100W port, and a 5dB quieter idle fan.
Is the DJI Power 1000 just a bigger, better version of the Anker SOLIX C300?
Not really — they're sized for different jobs. The C300 (288Wh, 9.1 lbs, $300) is built to disappear into a bag and keep phones and small gear charged [A1][A2]; the Power 1000 (1,024Wh, 28.7 lbs, $699) carries the 2,200W inverter to run real appliances. Bigger, yes. Better only if your loads actually need that headroom.
