Spec deltas
$199.99 buys the Anker SOLIX C300 DC six USB ports and zero AC outlets. $179 buys the Jackery Explorer 300D one AC outlet, three ports, and — now — a roughly $21 lower price. Same 288Wh battery, same 300W ceiling, same 3-year warranty, so the gap is what you can plug into it, and the price has quietly moved in the Jackery's favor.
For pure device charging, Anker is still the better tool on the axes that matter there: lighter, faster USB-C, and more ports to spread across. What it no longer is, is the cheaper one — and none of that changes the one thing it can't do: run anything that needs a wall outlet.
The Explorer 300D's single AC outlet and published 20ms UPS switchover are real, if modest, capabilities the Anker doesn't have at any price — literally: Anker doesn't publish a UPS spec at all, because it doesn't have one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The gap isn't in what either unit can deliver in watts — it's in what's plugged into it. Anker's cost per Wh is now $.69 against Jackery's $.62, so the Jackery has become the cheaper battery per watt-hour — a reversal of the lead Anker used to hold.
The SOLIX C300 DC costs $199.99 for 288Wh at 300W outputThe Explorer 300D costs $179 for the same 288Wh capacity and 300W output
Why it mattersFor a buyer who's never going to plug in anything but USB-C and USB-A devices, the C300 DC is still the faster, lighter tool — but it's now the pricier one, so that buyer pays a small premium for the DC-charging edge rather than saving.
Anker's own product name says it outright — 'DC' — and the spec sheet backs it up with a flat 0 in the AC Outlets column, not a smaller number.
The Explorer 300D has one AC outlet rated for 300W continuous with a 600W surge and a published 20ms UPS switchoverThe SOLIX C300 DC has zero AC outlets, no surge rating listed, and no UPS spec at all
Why it mattersAnyone whose plan includes even one wall-current device — a lamp, a CPAP power brick, a small appliance during an outage — should stop comparing price and just buy the Explorer 300D; the Anker isn't a smaller option for that job, it's not an option.
That speed advantage comes with 2.1 fewer pounds to carry, not a tradeoff against it — Anker is simultaneously the faster charger and the lighter unit.
The SOLIX C300 DC charges via USB-C at up to 140W; the Explorer 300D caps at 100WThe SOLIX C300 DC weighs 6.17 lbs against the Explorer 300D's 8.27
Why it mattersFor laptop and device charging specifically, the primary job a DC-only unit like this is built for, Anker is the faster and lighter tool — though no longer the cheaper one.
The Explorer 300D publishes worse-sounding numbers in places — 45dB isn't whisper-quiet — but at least gives you something to compare against; Anker's silence on noise, surge, and UPS could mean anything.
Anker doesn't publish a noise rating for the SOLIX C300 DC at all, while the Explorer 300D is rated 45dBAnker also lists no UPS spec and no surge rating, while the Explorer 300D publishes both
Why it mattersIf you're choosing on documented behavior rather than price, the Explorer 300D is the more transparent of the two, even though it loses on nearly every other spec.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: The AC-outlet/UPS gap, warranty math, and Anker's undisclosed noise spec are the core decision drivers.
rated cycles
The AC Outlets column reads 0 for the SOLIX C300 DC and 1 for the Explorer 300D, and that's the whole story in one line — Anker doesn't have a smaller AC capability, it has none. Pair that with Anker's blank UPS and surge-rating fields against Jackery's published switchover and surge numbers, and the Explorer 300D is the only one of these two with a documented backup-power role.
Anker also doesn't publish a noise rating at all, while Jackery states 45dB. That's not necessarily a mark against Anker's real-world noise — it might be perfectly quiet — but there's nothing on the spec sheet to hold it to, and an unpublished spec isn't a substitute for a number.
Lifetime Value
Selected because: Anker's cost-per-kWh advantage is the steepest of any pair in this batch and worth quantifying.
cost / lifetime kWh
The cost-per-kWh gap has actually flipped: Anker's $.69 per Wh now sits above Jackery's $.62, on batteries that share the same 288Wh capacity and 3,000-cycle rating. Nothing about longevity explains it — it's purely the sticker price, which now runs the other way.
Both share the same 3-year warranty, so there's no coverage tradeoff hiding in the math either. At $199.99 against $179, the Explorer 300D is now the better financial deal of the two — the C300 DC's case rests on its charging speed and weight, not on price.
Your Life, Your Pick
Selected because: Every scenario ties on capacity since both units share 288Wh and a 300W ceiling — worth saying plainly rather than pretending otherwise.
Every scenario on this page lands the same way for both units, and it's worth saying plainly rather than pretending there's a winner: same 288Wh capacity, same 300W output ceiling, so the energy math is identical down to the percentage point for Weekend Camping, the 8-hour blackout, CPAP overnight, the remote workday, and van life. Neither has the tank for any of them.
Tailgate Party isn't really an exception — both units fail it the same way, output-limited rather than energy-limited, because neither's 300W ceiling can power the scenario's 400W blender. For once, scenario math isn't the deciding factor on this page at all; spend the mental energy on price and the AC-outlet question instead.
Portability & Form Factor
Selected because: Anker is the lightest unit in this batch and it's a real, unambiguous win.
weight
6.17 lbs is genuinely light — 2.1 lbs under the Explorer 300D, and the lightest unit across every comparison in this batch. That's a real, uncomplicated win, not a marginal one.
It's also not bought at the expense of charging speed: Anker's faster USB-C means the lighter unit is also the quicker one to top off a laptop. There's no tradeoff to explain away here, which is rare on this page.
Brand Trust
Selected because: Anker's app and value proposition edge out Jackery's, reinforcing the price case.
Anker's app rates 4.5 on iOS and 4.3 on Android, both ahead of Jackery's 2.3-to-3.3 range split across two confusing apps. For a unit you're monitoring by phone, that's a real day-to-day difference.
Support is closer to a wash: Anker's has reportedly softened from its historically excellent standard, and Jackery's is criticized for scripted responses and strict receipt requirements. Neither brand gives you a strong reason to pick it on support alone.

Conclusion
July 14, 2026
Verdict: the Anker SOLIX C300 DC
Take the SOLIX C300 DC for pure device charging — 2.1 lbs lighter, faster USB-C (140W vs 100W), and more ports, on a battery that matches the Explorer 300D everywhere else: same 288Wh, same 300W ceiling, same 3-year warranty. The price has shifted, though: at $199.99 the C300 DC now costs about $21 more than the $179 Explorer 300D, so it's the pricier unit rather than the value pick. And it still has zero AC outlets and no UPS spec, while the Explorer 300D has one AC outlet with a published 20ms switchover. If your plan includes even one wall-current device, or you just want the cheaper unit, buy the Explorer 300D; the C300 DC earns its keep only if you want the lightest, fastest DC-only charger and will never need AC.

Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, SOLIX C300 DC rates 4.2/5 (52nd percentile of 22 Personal-class units), and Explorer 300D rates 4.8/5 (86th percentile of 22 Personal-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
45dB Against an Unknown
Jackery states 45dB for the Explorer 300D. Anker doesn't publish a number for the SOLIX C300 DC at all. A stated 45dB is at least something to plan around; an unpublished spec could be quieter or louder, and there's no way to check from the spec sheet alone.
Same Years, Different Money
Both units carry a 3-year warranty, so the coverage length is identical. What differs is what you're paying for each year of it: roughly $67 a year for the SOLIX C300 DC against $60 for the Explorer 300D — a small edge that now tips to the Jackery.
Battery Lifespan in Real Years
The Explorer 300D is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. After hitting the cycle limit, the battery doesn't die. It drops to ~80% original capacity, which is still very usable.
The Blank Field
Anker's spec sheet leaves noise level blank for the SOLIX C300 DC. That's not automatically bad — plenty of DC-only units with no fan-heavy inverter run quiet — but it means there's nothing published to hold the unit to, unlike the Explorer 300D's stated 45dB.

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
Anker's SOLIX C300 DC backs its parent brand's consumer-electronics trust with the fastest USB-C charging speed in this comparison and the lighter build of the two.
Worth knowing
SOLIX-specific support has reportedly softened from Anker's historically excellent standard, trending toward more generic AI-driven first-line responses.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Jackery's brand recognition and retail footprint are the widest in the category, and the Explorer 300D is the only unit here with a documented AC outlet and UPS switchover spec.
Worth knowing
The app is the weakest of the major brands — though the Explorer 300D no longer carries a price premium over the Anker; it now undercuts it by about $21 while adding an AC outlet and a UPS spec.
Analyst note
Anker's app is the stronger one, and the C300 DC is the lighter, faster-charging tool; but Jackery now holds the value edge too, undercutting the Anker by about $21 while adding the AC outlet and UPS spec the C300 DC lacks. Whether the Anker is worth its small premium depends entirely on whether you'll only ever charge over USB.
Growth path

Analyst note
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 SOLIX C300 DC 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
Owners describe the SOLIX C300 DC as deliberately built around what it drops rather than what it adds — no AC inverter, kept to about 6.2 lbs as a resultA1. Two-way USB-C with PD 3.1 is the headline feature, recharging the unit itself to 80% in about an hourA2.
Field feedback on capacity is positive but modest in scope: enough to charge a phone and laptop several times, run a fan for hours, or power a small light setupA3. It's consistently positioned as a device-charging tool for modern travelers rather than a backup-power unit — app integration and solar support are there, but running AC appliances explicitly isn't the jobA4.

Against a competitor with zero AC outlets, the Explorer 300D's owner coverage doesn't dwell on the outlet itself so much as the overall shape: a compact, vertical, speaker-like unit reviewers single out as small for its 288Wh capacityB2, built around one AC outlet alongside its USB-C and USB-A ports.
It's rated around 4.3 out of 5 and aimed at digital nomads and outdoor device usersB4, but there's no field data yet on how that one AC outlet or its 20ms switchover perform under real, repeated use — the reviews on record are first impressions, not months-later verdicts.

Who Should Buy Which
Buy the SOLIX C300 DC if you…
- →You're charging phones, laptops, and drones and never plan to plug in anything that needs a wall outlet — Anker is lighter and faster at that exact job (140W USB-C against 100W).
- →You want the most USB-C ports and the fastest PD charging speed in this class.
Buy the Explorer 300D if you…
- →You need even one AC-outlet device covered — a lamp, a CPAP power brick, a small appliance — or want a unit with a published UPS switchover spec; and it's now the cheaper of the two on top of that.
If neither fits
If your actual need is running real appliances or getting through a multi-day outage, skip both — 288Wh and a 300W ceiling can't cover Weekend Camping, an 8-hour blackout, or van life regardless of which one you buy. Look at a station with a real AC inverter rated well above 300W.
The Bottom Line
Same battery, same output ceiling, same warranty — and the one hard difference is a column on the spec sheet: AC Outlets, 0 against 1. The price gap has narrowed and flipped: the C300 DC now runs about $21 more than the Explorer 300D. For pure device charging it still wins on weight and USB-C speed — it's just no longer the cheaper way to get there.
But if there's even one wall-current device in your plan, or you want a documented UPS switchover, that single outlet is worth more than everything else on this page combined — and the Jackery is now the cheaper unit too. Buy the Anker for the lightest, fastest USB-only charging. Buy the Jackery the moment anything needs to plug into a wall, or if you just want to spend less.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Does the Anker SOLIX C300 DC have an AC outlet?
No. It has zero AC outlets — the 'DC' in the name is literal. It's built entirely around USB-C, USB-A, and solar or car-socket input, with no inverter at all. The Jackery Explorer 300D has one AC outlet rated for 300W continuous with a 600W surge, which is the one thing the Anker can't do at any price.
Which one is cheaper?
The Explorer 300D now, by about $21 ($179 vs the C300 DC's $199.99) — a reversal from when the Anker held a wide price lead. The two still match on capacity (288Wh), output (300W), cycle rating (3,000), and warranty (3 years), so the gap tracks to what each unit can plug into, not what it can hold.
Which charges a laptop faster?
The Anker SOLIX C300 DC, via USB-C at up to 140W against the Explorer 300D's 100W cap. That's on top of being 2.1 lbs lighter, so there's no tradeoff between charging speed and portability here.
Does either one work as a UPS?
Only the Explorer 300D. It publishes a 20ms switchover spec; the SOLIX C300 DC lists no UPS capability and no surge rating at all. If backup power for a router or similar device is the plan, the Anker isn't built for it.
Is the Anker SOLIX C300 DC loud?
Unknown from the spec sheet — Anker doesn't publish a noise rating for it at all, while Jackery states 45dB for the Explorer 300D. That's not evidence it's louder or quieter, just that there's nothing published to check it against.
