Anker SOLIX C300 DC vs Goal Zero Yeti 500X

The Yeti 500X's one irreplaceable trick is the AC outlet the DC-only C300 can't fake; on price, weight, cycle life, and charging speed the Anker wins clean, so the whole decision is simply whether your gear needs a wall plug.

One of these has a wall outlet; the other can't produce one at any wattage. The Anker SOLIX C300 DC is a DC-only unit, all USB ports and a 12V socket with no inverter, so its 300W rating is what those ports move, not what a wall plug sees. The Goal Zero Yeti 500X carries a real inverter behind a single AC outlet. Before price, weight, or battery size, that line decides whether these two are even in the same conversation for your gear.

For the job they actually share, charging phones, laptops, cameras, and 12V gear, take the Anker. It's $200 to the Yeti's $500, weighs 6.2 lbs against 12.9, and is rated for 3,000 charge cycles where the Yeti manages 500. It wins the light-duty lane on every axis that isn't raw capacity, and it isn't close.

The Yeti's counterpunch is that outlet, plus 209Wh more battery. Both are real. But 497Wh at 300W is too small to run the things people buy AC power stations for: a fridge through a blackout, a campsite for a weekend, and a van's daily loads all come back short for both units. So the Yeti's versatility is genuine and narrow at the same time. It can feed a lamp or a small AC gadget the Anker can't, yet it can't scale up to the emergencies that make AC feel essential.

02

What the Numbers Reveal

Each conclusion stated first — the numbers behind it on one line, the full analysis below.

F1

Every heavy AC job people buy power stations for outruns the Yeti too. 422 usable Wh is roughly a quarter of a single blackout night, so the outlet is real yet it tops out at powering a lamp or a laptop brick, not surviving an outage. That's a $300 premium for capability the battery can't back.

Anker C300 DC: 0 AC outlets, DC-only, its 300W is a USB and 12V port total with no inverterYeti 500X: real inverter, 1 AC outlet, 497Wh, 300W continuous with 600W surge8-Hour Blackout needs about 1,645Wh, Weekend Camping about 2,100Wh, Van Life about 4,685Wh, all 'neither', and the Yeti holds only 422 usable Wh

Why it mattersIf you want true AC backup, neither box qualifies; if you only ever charge USB and 12V gear, you're paying extra for an outlet you'll never plug into.

F2

cost / lifetime kWh

Per kilowatt-hour you actually pull from it, the Yeti runs about $2.01 to the Anker's $0.23, nearly nine times as much, and it charges that premium on the outgoing chemistry it's already replacing.

Anker C300 DC: 3,000 cycles, $200, 288Wh, works out to $0.23 per lifetime kWh and about 864 kWh totalYeti 500X: 500 cycles, $500, 497Wh, works out to $2.01 per lifetime kWh and about 249 kWh totalThe Yeti uses older Li-NMC cells, since replaced by an LFP Yeti 500B1B4

Why it mattersAnyone keeping the unit for years rather than months should read the Yeti's price tag as buying less usable life, not more.

F3

weight

There the Anker is simply the better version of the same thing: about half the weight, more than twice the USB-C output, and a roughly one-hour top-up, while the Yeti brings nothing to this job except more mass.

Afternoon Off-Grid, about 100Wh, is the one scenario both units finish comfortablyAnker C300 DC weighs 6.2 lbs, Yeti 500X weighs 12.9 lbsAnker pushes up to 140W over USB-C against the Yeti's 60W, and refills to 80% in about an hourA2

Why it mattersThe device-charging buyer gets a lighter bag and faster charging by taking the cheaper unit, full stop.

The specific dimensions that decide these two units — everything else is a tie.

What the Specs Don't Tell You

Selected because: The Anker is DC-only and the Yeti carries an AC inverter, the single line that decides whether your gear even plugs in, before any other spec matters.

rated cycles

The C300 DC's 300W isn't an inverter rating, it's the sum of what its USB and 12V ports can push. Plug a $12 box fan into it and nothing happens, because there's no socket to plug into. The Yeti 500X carries a real inverter behind one AC outlet, so a lamp, a fan, or a laptop's wall brick all work. Decide which side of that line your gear sits on, and most of this page is already settled.

The smaller cards all tilt the same way the big one does. The Anker checks its charge and pings low-battery alerts to your phone while the Yeti makes you walk over and read the front panel, and Anker backs its unit for three years to Goal Zero's two. None of those decide anything on their own. They just mean the older, pricier unit isn't buying you maturity anywhere obvious.

Lifetime Value

Selected because: 3,000 cycles against 500, at $200 versus $500, drives a lifetime-energy gap of $0.23 vs $2.01 per kWh that's too big to ignore.

cost / lifetime kWh

Nearly nine times. That's how much more the Yeti costs per kilowatt-hour you'll actually pull from it over its life, $2.01 against the Anker's $0.23, and it isn't close enough to argue with. The math behind it is brutal for the Yeti: 500 charge cycles of a 497Wh pack is about 249 kWh of total energy, while the Anker's 3,000 cycles of 288Wh come to roughly 864 kWh, about three and a half times more, for $300 less up front.

The reason is chemistry the Yeti can't fix. It runs older Li-NMC cells that Goal Zero has already replaced with an LFP Yeti 500B4, so you'd be paying a premium for the outgoing pack. After the rated cycles neither battery dies; both settle to about 80% of original capacity and keep going. The Anker just takes six times as long to get there.

Your Life, Your Pick

Selected because: Both are small units; the scenarios show exactly which jobs each can finish and where both fall short.

Line up the load profiles and a pattern jumps out: almost everything comes back 'neither'. Weekend camping wants about 2,100Wh, an eight-hour blackout about 1,645, a van-life day about 4,685, and both units are a fraction of all three. These are small batteries, and no framing changes that. The honest read is that neither is an outage plan or a campsite power supply.

Two jobs actually separate them. A humidified CPAP night, about 320Wh, is the one overnight load a DC unit can attempt, and here the Yeti's larger pack matters: it finishes with 102Wh to spare while the Anker stops 75Wh short. But drop to a light afternoon off-grid load and both cruise it, the Anker at 41% used and the Yeti at 24%, at which point capacity stops mattering and the lighter, cheaper unit wins by default.

Portability & Form Factor

Selected because: At roughly double the weight for the Yeti, portability is the tiebreak in the light-duty jobs both units can actually do.

weight

This is the difference between a unit you sling into a daypack with two fingers and one you carry like a small toolbox. The Anker is about half the weight of the Yeti, and for batteries this size that's not a footnote, it's most of the point. Nobody cross-shopping a 288Wh and a 497Wh box is planning to run a house; they're deciding what rides in the bag.

The weight gap comes with a charging-speed gap pointing the same direction. The Anker moves more than twice the USB-C wattage of the Yeti, so it refills a laptop faster and, with a strong enough input, tops itself back to 80% in about an hourA2. The heavier unit is also the slower one to feed. If your kit lives in a bag you actually carry, this section alone is the argument.

Will It Power Your Gear?

Scenario math and per-appliance runtimes, modeled from the spec record.

Scenario verdicts

We ran the math on seven real-world scenarios. Here's which unit survives your actual life.

SCN-01 · 2 nights · needs 2,100Wh

Weekend Camping

Two nights off-grid with essential comfort

Neither unit

The SOLIX C300 DC has no AC outlets, so the led lights and box fan in this scenario never plug in — it's a DC station for USB and 12V gear, and no wattage figure changes that, so capacity never gets a say. This is the wrong kind of unit for the job rather than a close call. The Yeti 500X doesn't have the energy either — 422Wh usable against 2,100Wh, 1,678Wh short — so neither route works.

SCN-02 · 8 hours · needs 1,645Wh

8-Hour Blackout

Keep the essentials running through a night without power

Neither unit

Neither box is an outage plan. The fridge, router, and modem all want wall outlets the Anker doesn't have, so it sits the night out completely. The Yeti can actually power them, for a while: its 422 usable Wh is about a quarter of the roughly 1,645 an eight-hour night needs, so the lights go out well before morning. If blackout backup is why you're shopping, both are the wrong size, and this is a job for a unit several times larger.

SCN-03 · 8 hours · needs 320Wh

CPAP Overnight

Sleep therapy without interruption — the #1 medical use case

Yeti 500X

This is the one overnight job a DC unit can attempt, since plenty of CPAPs run off 12V and skip the wall outlet the Anker lacks. But a humidified night draws about 320Wh, and the Anker's 245 usable Wh stops 75Wh short, roughly three-quarters of the way there. The Yeti finishes the same night with 102Wh in reserve. If your machine runs on 12V and your nights are humidified, that spare capacity is the entire reason to pay up.

Remote Workday

Full work day off-grid without power anxiety

Neither unit

The SOLIX C300 DC has no AC outlets, so the external monitor and router + modem in this scenario never plug in — it's a DC station for USB and 12V gear, and no wattage figure changes that, so capacity never gets a say. This is the wrong kind of unit for the job rather than a close call. The Yeti 500X doesn't have the energy either — 422Wh usable against 910Wh, 488Wh short — so neither route works.

Tailgate Party

Game day power for the crew

Neither unit

Neither runs the party. The blender and TV want wall outlets, so the DC-only Anker is out before the burgers are off the grill. The Yeti's 600W surge can jolt a 400W blender to life, but its 300W continuous rating can't hold it there, and its 422 usable Wh would run dry about 248Wh short of the 670 the afternoon needs anyway. Bring a bigger battery, or bring ice.

Van Life Daily

A full day of mobile living — the ultimate endurance test

Neither unit

The SOLIX C300 DC has no AC outlets, so the mini-fridge, led lights and the rest in this scenario never plug in — it's a DC station for USB and 12V gear, and no wattage figure changes that, so capacity never gets a say. This is the wrong kind of unit for the job rather than a close call. The Yeti 500X doesn't have the energy either — 422Wh usable against 4,685Wh, 4,263Wh short — so neither route works.

Afternoon Off-Grid

Phones and a speaker at the park, beach, or campsite — the small-unit job description

Either unit

This is the job small stations are actually for, and both do it: the SOLIX C300 DC finishes at 41% used, the Yeti 500X at 24%. At this size the decider is what rides in the bag — 6.2 lbs for the SOLIX C300 DC against 12.9 for the Yeti 500X — and price, not the leftover watt-hours.

Conclusion

August 30, 2026

Verdict: the SOLIX C300 DC

Take the Anker SOLIX C300 DC unless you specifically need a wall outlet. For the device-charging job these two share, it wins on every axis that isn't raw capacity: $300 cheaper, roughly half the weight, six times the cycle life, and far cheaper per kilowatt-hour over its life. The Yeti 500X's one irreplaceable card is the AC inverter the DC-only Anker lacks, but at 497Wh and 300W it's too small to carry the fridge-through-a-blackout jobs that make AC feel essential, so that outlet mostly powers a lamp or a laptop brick. Buy the Yeti if you have a specific low-draw AC device and won't carry a separate inverter, or if a heavier overnight load like a humidified CPAP needs the extra 209Wh. If you need real outage backup, skip both and size up to a larger LFP unit.

Test Notes & Caveats

Hidden gotchas and advantages we spotted that you won't find on the product page.

[CAUTION]

SOLIX C300 DC: No AC Outlets At All

The SOLIX C300 DC's 300W is a DC port total — USB and 12V — not an inverter rating. Anything with a wall plug (a fridge, a TV, a coffee maker, most fans and lamps) never plugs in, at any wattage. That's the design, not a defect: it buys weight, silence, and efficiency for phone, laptop, camera, and 12V-CPAP loads. The Yeti 500X carries a real inverter behind 1 AC outlet, so it plays in both worlds. Decide which side of that line your gear lives on before weighing anything else on this page.

[NOTE]

An app on one, a walk to the other

The Anker reports its charge and pushes low-battery alerts to your phone; the Yeti 500X makes you walk over and read the front panel. Genuinely handy day to day, and genuinely not a tiebreaker. The one moment you might want a remote read is a blackout, which is also when you're standing right next to the thing anyway.

[NOTE]

Three years against two, and why it matters here

Anker covers the C300 DC for three years to Goal Zero's two. On its own, a single year of coverage is a tiebreaker, not a reason to buy. It earns its place only stacked on the cycle-life gap: the unit built to last far longer is also the one its maker stands behind longer.

[NOTE]

Battery Lifespan in Real Years

The SOLIX C300 DC is rated for 3,000 cycles vs 500. In real life: at daily use, that's 8.2 vs 1.4 years. At weekend use (twice a week), it's 29 vs 5 years. One caution reading years across different sizes: a cycle is 288Wh on the SOLIX C300 DC and 497Wh on the Yeti 500X, so count lifetime energy — roughly 864 kWh against 249 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Brand trust

Anker

Ecosystem

7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system

Support

US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.

Community

Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.

App experience

Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android

Unique strength

Rides Anker's consumer-electronics reputation, and the InfiniPower cell design behind that 3,000-cycle rating is the real thing. Across the mid-size and larger SOLIX line, Anker is among the stronger dollar-per-watt-hour buys in the category.

Worth knowing

SOLIX-specific support has slipped from Anker's old no-hassle standard toward scripted, AI-agent responses, and firmware updates have quietly pulled features. The hardware here is newer and cheaper; the service isn't the differentiator it once was.

Goal Zero

Ecosystem

Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series now out of stock across every model on Goal Zero's own store (checked 2026-09-13: 200X, 500X, 1000X, 1500X, 3000X, 6000X, some listed only as open-box), so buying one new means finding retailer stock, Sherpa power banks for the under-100Wh tier, plus Alta coolers, Nomad/Ranger solar panels, and vehicle integration kits

Support

US-based company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.

Community

Small but loyal — strong following in overlanding and preparedness communities. Official community forums were recently shuttered, frustrating long-time users.

App experience

Rated 4.4/5 iOS (~1,200 ratings) but recent reviews skew negative — recurring connectivity issues, crashes, and stability problems.

Unique strength

The company that started this category, US-based, with genuinely rugged, weather-minded designs and a tight Yeti-Ready ecosystem of coolers, lights, and vehicle kits. The heritage is real.

Worth knowing

This 500X is the outgoing Li-NMC generation, already replaced by an LFP Yeti 500. Support has drifted from its premium reputation, with long waits and the official community forums recently shut down, so the price premium buys less service cover than it used to.

All Goal Zero power stations tested →

Analyst note

Both brands' support has come down from a high, so neither wins this on service the way it might have two years ago. On the hardware in front of you, the Anker is the newer, cheaper, longer-lived design and the Goal Zero is the heritage pick you pay a premium to own. Buy the story only if you also need the outlet.

Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the Yeti 500X gives you the larger ceiling); you can't add to either later.

What Owners Report

Patterns from published owner reports and long-term reviews — every claim cited to its source below.

Anker SOLIX C300 DC

Field data is still thin here, the C300 DC is a new unitA0, so what exists is reviewer-level rather than years of ownership. The consistent notes are the light DC-only build at about 6.2 lbs and the fast two-way USB-C that refills the unit to 80% in roughly an hourA1A2, plus early owners charging phones and laptops several times over and running a fan for hours on a chargeA3. The recurring framing is a device charger for modern travelers, not an appliance runnerA4.

A 288Wh unit that ditches the heavy AC inverter to focus on DC power, keeping it very light at about 6.2 lbs.

Goal Zero Yeti 500X

The Yeti 500X reads as compact and well-built for its size, among the more portable 505Wh-class stations at 12.9 lbsB2, with owners reliably charging laptops, a Switch, an iPad, and phones without troubleB3. The steady knock is the chemistry: a 500-cycle Li-NMC pack that a newer LFP Yeti 500 has since replacedB1B4. Nobody reports it failing at the light-duty work; they report that a longer-lived design now exists next to it.

Weighs 12.9 lbs and is one of the most compact 505Wh power stations, with praised portability and build quality.

Who Should Buy Which

Buy the SOLIX C300 DC if you…

  • The traveler whose whole kit charges over USB-C or 12V, the phone, the laptop, the camera, a drone battery or two. At about six pounds it rides in the daypack you're already carrying, and its fast USB-C tops a laptop back up on the move.
  • The buyer who wants the unit to still work eight years from now: the cycle rating is over eight years of daily top-ups, and its lifetime energy comes out close to free per kilowatt-hour.
  • Anyone who already owns a larger AC station for the house and just wants a light DC runner for trips and the nightstand.

Buy the Yeti 500X if you…

  • The person who needs a wall socket for one specific low-draw device the Anker can't feed, a small AC-only gadget, and won't carry a separate inverter to get it.
  • The heavier-overnight buyer: a humidified CPAP night runs about 320Wh, past the Anker's 245 usable but inside the Yeti's 422, so the bigger pack is what finishes the night.
  • The buyer who values one box that covers both AC and DC over the lightest, cheapest option, and accepts the shorter-lived NMC pack to get it.

If neither fits

If the plan is a fridge through a multi-hour blackout, a weekend campsite, or a van's daily loads, both are too small; every one of those comes back short for the pair. That's a job for a larger LFP unit with a real inverter, a size class up from these two. Size it for your needs up front, since neither of these expands.

08

The Bottom Line

The whole page reduces to one question the Anker answers by leaving it out: does your gear need a wall plug? If it doesn't, the C300 DC is the better unit and it isn't a hard call, lighter to carry, roughly half the price, six times the cycle life, and far cheaper per kilowatt-hour across its life. The Yeti's inverter is its one true advantage, and 497Wh is a ceiling low enough that the outlet can light a lamp but not survive a blackout.

So buy the Yeti 500X only if a specific low-draw AC device or a heavier overnight load makes that outlet or its extra 209Wh worth $300 and double the weight. If you need genuine outage backup, close this tab and step up to a larger LFP unit. Everyone else, the person with a bag full of USB-C, takes the Anker and pockets the difference.

Frequently Asked Questions

Answers drawn from the spec record and cited owner research.

Can the Anker SOLIX C300 DC run AC appliances?

No. It's a DC-only unit with no inverter and no wall outlets, and its 300W rating is the total across its USB and 12V ports. Anything with a two-prong plug, a lamp, a TV, a coffee maker, won't run on it at any wattage. If you need a wall socket, that's the Yeti 500X's job in this matchup.

Why is the Goal Zero Yeti 500X more than twice the price for the same wattage?

You're paying for the AC inverter and the larger 497Wh battery versus 288Wh, not more continuous output, since both are rated 300W. Whether that's worth $300 comes down entirely to whether you need the wall outlet. If your gear is all USB and 12V, it isn't.

Which lasts longer, the C300 DC or the Yeti 500X?

The C300 DC, by a wide margin. It's rated for 3,000 charge cycles against the Yeti's 500, roughly eight years of daily use versus under two. The Yeti uses older Li-NMC cells that a newer LFP model has since replaced, and even after their rated cycles both packs keep working at about 80% capacity.

I just want to charge phones, a laptop, and a camera on trips. Which one?

The C300 DC. It's half the weight at 6.2 lbs against 12.9, it's $300 cheaper, and it pushes up to 140W over USB-C against the Yeti's 60W, so it tops a laptop up faster. For a pure device-charging kit, the Yeti's AC outlet and extra capacity are dead weight.

Is the Yeti 500X a good backup for a power outage?

Not really. At 497Wh and 300W it can keep phones, a laptop, and a light going, but a typical eight-hour blackout with a fridge, router, and lights needs about 1,645Wh, more than three times what it holds. For genuine outage backup, look a size class up at a larger LFP unit with a real inverter.
