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.

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 $91 more (on last listed prices) or a slightly heavier bag.
Decided 7 matchups · read one →
Anyone who wants a grab-and-go unit that lives in the trunk and gets carried to the picnic table without a second thought.
Decided 4 matchups · read one →
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.
Decided 3 matchups · read one →
Your loads are phones, tablets, laptops, and small gadgets, not appliances that spike hard on startup [A1][A4].

A rival won when…
You want the lower price ($239, last listed price) and the lighter body (7.8 lb).
Decided 6 matchups · read one →
The value buyer: the same 288Wh battery for $30 less, and the cheaper one to own over its life.

The homeowner who wants partial-home backup that rides out a multi-day outage instead of a single evening.

You run a CPAP away from a wall outlet. It's the only unit here that finishes the 320Wh night, and it ends with 166Wh still in the tank.

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.

From the test desk
“Default to the SOLIX C300.”
“Buy the C300X unless you want a battery with no app layer at all or need the C300's second USB-A port — and know that at today's prices that choice costs you.”
“The batteries match in size but not in kind: 288Wh each, but only the Anker has an inverter and AC outlets, while the Jackery is DC-only and rated for 4,000 cycles to the Anker's 3,000.”

Questions people ask
What solar panels work with the SOLIX C300?
Any panel between 11 V and 28 V, through its XT60 input, up to 100 W. 12 of the 39 panels we track work with it. Our pick: the Renogy 200W Portable Solar Panel Blanket. One panel delivers 100 W, the most the input takes.
Is the SOLIX C300 worth $190 more than the C200 DC?
Only if you need what that $190 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 actual difference between the Anker SOLIX C300 and C300X?
On every spec we track, almost nothing: same 288Wh, 300W output, 600W surge, 140W USB-C fast charging, a 10ms UPS rating, published 25 dB, 3,000 cycles, and five-year warranty. The ports are the difference: the C300 has two USB-A ports to the X's one, and Anker lists two 140W USB-C ports on the C300 where it states a single 140W figure for the X. The C300X is the up-trim 'X' version that adds the Bluetooth app and monitoring layer, and at current prices it costs $30 less, not more. If you won't use the app, you're still buying the same hardware at two prices, and the X is the lower one.
Is the Anker SOLIX C300 better than the Jackery Explorer 300D?
For many buyers, yes — but it's the pricier pick. They share the same 288Wh capacity, and the C300 adds three AC outlets where the DC-only 300D has none, a UPS mode, a five-year warranty against three, and a lower published noise figure, 25 dB against 45. The catch is price: the C300 costs about $151 more, and the 300D's edges are that it's 3.6 lb lighter, rated for 4,000 cycles to the C300's 3,000, and the cheaper of the two.
What's actually different between the SOLIX C300 and the SOLIX C300 DC?
The battery, cycle life, and USB-C charging speed are identical — 288Wh, 3,000 cycles, dual 140W ports on both. The real difference is the C300's AC inverter: 600W of surge capacity and a 10ms UPS switchover the DC doesn't have, because Anker's own spec sheet lists zero AC outlets on the DC.
