Anker SOLIX C300 vs Jackery Explorer 300D
Two identical 288Wh batteries, now priced about $91 apart — and this time the pricier one is the Anker, which still wins on outlets, warranty, switchover speed, and noise. The Jackery's rebuttal is that it's under a pound lighter and about $91 cheaper.

Spec deltas
Line up the two spec sheets and the row that matters is identical: 288Wh of capacity on each, both rated for 3,000 charge cycles. Runtime lives in the battery, the batteries match, so this was never going to be decided by how long either one lasts on a charge.
Everything that isn't the battery favors the Anker. The SOLIX C300 lists three AC outlets to the Explorer 300D's one, a 140W USB-C port against 100W, a five-year warranty against three, a sub-10ms UPS switchover against sub-20ms, and a 25 dB noise floor against 45 dB under load. What it no longer does is cost less: it's now $269.99 against the Jackery's $179, about $91 more.
The Jackery's answer to all of that is that it's under a pound lighter, about $91 cheaper, and that it comes from the brand you can buy at Costco and hand back across the same counter. Those are real, and now they add up to more than before. For many buyers the verdict is still the Anker — it does more, with more outlets, a longer warranty, and a quieter, faster build — but it now asks a ~$91 premium and gives up weight, so the call is closer than it was.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Price
The warranty complicates it. The Anker now costs more up front, but it's covered for five years against three, which pencils out to about $54 per covered year against the Jackery's $60. So the pricier sticker is still the marginally cheaper one to own per warranted year — the one place the cost math hasn't flipped.
the C300 holds 288Wh and costs $269.99the Explorer 300D holds 288Wh and costs $179both are rated for 3,000 charge cycles
Why it mattersSo the usual instinct half-holds here: the pricier station is now the Anker, and it is the better-covered, better-specced one — but you pay about $91 more up front, and whether that's worth it comes down to needing the outlets, the quiet, and the UPS.
That switchover gap is a category difference, not a rounding error: the engine reads the C300's sub-10ms as line-interactive and the 300D's sub-20ms as standby. Sitting under a desk guarding a router or a mini-PC, line-interactive is the one that holds voltage steady through a flicker without a reboot.
the C300 has three AC outlets and a top USB-C port of 140Wthe Explorer 300D has one AC outlet and a top USB-C port of 100Wthe C300 switches to battery in under 10ms versus the 300D's under 20ms
Why it mattersIf the job is a quiet always-on backup for sensitive electronics, the C300 is built for it and the 300D is a charger that also has an outlet.
The noise only shows up under load, exactly when you're fast-charging a laptop off that 140W port or topping up overnight. At 45 dB the Jackery's fan is audible from across a quiet room; at 25 dB the Anker stays near-silent doing the same work.
the C300 runs at 25 dBthe Explorer 300D reaches 45 dB under loadboth are palm-sized device chargers meant to sit close to you
Why it mattersIf this ever charges your phone or CPAP two feet from your pillow, the noise spec settles it before any other number does.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The whole verdict lives here: identical lifetime energy, and the cheaper unit is also the longer-warrantied one.
cost / lifetime kWh
This table usually breaks a tie; here the price has crossed since launch. Both batteries store 288Wh and carry the same 3,000-cycle rating, so each delivers the same 864 kWh over its life. The Jackery now charges you less to get there, $179 against $269.99, which is the entire reason its cost per lifetime kWh now comes in lower. There's no efficiency trick, just a smaller sticker on the same battery, and it's now the Jackery's.
The warranty is the one place the money argument still favors the Anker. It covers the C300 for five years, Jackery covers the 300D for three, so the Anker's protection costs about $54 per covered year against the Jackery's $60. So while the Jackery is cheaper to buy and cheaper per lifetime kWh, the C300's longer coverage makes it marginally cheaper per warranted year — the money argument now splits rather than running one direction.
Portability & Form Factor
Selected because: The Jackery's one and only computed win (weight) is here; voice it honestly, then price it against what it costs.
weight
Give the Jackery its due, because this is the one row it wins. The Explorer 300D weighs 8.27 lb to the C300's 9.1, and its upright, speaker-shaped bodyB2 stands apart from the typical power-station box. If you're the person carrying it every day and counting every ounce, that under-a-pound difference is genuine.
It's also no longer the whole of the Jackery's physical case — it now pairs that lighter body with the lower price, about $91 under the C300. Reviewers call the Anker impressively compact and light for 288Wh in its own rightA2, so this isn't heavy versus light, it's light versus slightly lighter. Eight-tenths of a pound is about a full soda can, but it now comes bundled with the cheaper sticker, so weigh the C300's two extra outlets and longer warranty against both.
What the Specs Don't Tell You
Selected because: All three firing cards (noise, ups, warranty) point the same way; a clean sweep is itself the finding.
rated cycles
Three gotcha cards fire on this pairing, and the Anker sweeps all three. It's quieter (25 dB versus 45 under load), it hands off to battery faster (under 10ms versus under 20), and it's warrantied longer (five years versus three). None of these is a dramatic gap on its own; together they're the Anker's real case now that the price row has crossed to the Jackery — capability the cheaper unit simply doesn't match.
The switchover card is the one worth a second look. The engine grades the C300's sub-10ms handoff as line-interactive and the 300D's sub-20ms as standby, a real topology difference if you're using either as a desk-side backup. For plain device charging it's academic; for a mini-PC or a modem you can't afford to reboot, it's the tiebreaker.
Brand Trust
Selected because: Cross-brand pair where Jackery's retail reach is its best counter to losing the spec sheet.
This is where the Jackery earns part of its keep. Anker brings the stronger app, its SOLIX app clears 4.5 stars on iOS while Jackery's sit at the bottom of the category. Jackery brings distribution: Costco, Home Depot, Best Buy, Amazon — plus, now, the lower price. For a sub-$300 purchase, the counter you can walk a defective unit back to is worth real money, and Jackery has more of them.
Neither support story is spotless. Anker's once-famous no-hassle replacements have drifted toward scripted AI agents, and Jackery's warranty service draws its own criticism, which is exactly why buying a 300D from a retailer with a generous return window is the smart hedge. On the brand row Jackery now leads on both price and reach — the Anker's counter is its stronger app, its longer warranty, and its fuller spec sheet.

Conclusion
July 13, 2026
Verdict: the Anker SOLIX C300
The batteries are twins: 288Wh each, both rated for 3,000 cycles, so runtime and lifespan are settled before you compare anything else. From there the Anker SOLIX C300 wins the spec sheet: three AC outlets to the Jackery's one, 140W from its top USB-C port against 100W, a five-year warranty instead of three, a sub-10ms switchover instead of sub-20, and 25 dB where the Explorer 300D hits 45 under load. What's changed is price — the C300 now costs about $91 more ($269.99 against $179), so it's the premium pick, not the value one. It's still more charger, and its longer warranty even makes it marginally cheaper per covered year, but you're paying up front for the capability. Take the C300 if you want the extra outlets, the quiet, and the faster UPS and USB-C; take the Jackery if the lower price and lighter weight matter more.

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 rates 4.4/5 (67th 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.
25 dB versus 45 dB
The C300 works at about 25 dB; the Explorer 300D climbs to 45 dB when its fan spins up under load. That's roughly the jump from a library to a refrigerator's hum. On a unit small enough to live on a nightstand, the quieter fan isn't a luxury spec, it's whether the thing wakes you at 2 a.m. while it tops off your phone.
Line-interactive versus standby
Both units switch to battery fast, but not the same fast. The C300's sub-10ms handoff grades as line-interactive; the 300D's sub-20ms grades as standby. For charging phones it makes no difference. For a desk-side router or mini-PC that can't take a reboot, line-interactive is the one that rides through a flicker without dropping the load.
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.

Community
The smallest enthusiast community of the major brands, though name recognition keeps its YouTube presence healthy.
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
Availability and recognition, the dependable, everywhere-in-stock default of power stations, easy to buy and easy to return.
Worth knowing
The weakest app experience among the majors, with multiple confusing apps and a mandatory login even offline. Slowest of the big brands to move fully to LFP.
Analyst note
Two different bets for a sub-$300 charger. Anker gives you the better app, the longer warranty, and the fuller spec sheet; Jackery gives you the lower price now, about $91 less, and the store you can walk the unit back into if it arrives wrong. The Anker's capability edge is real, but it's no longer the cheaper bet, so the choice comes down to whether you need the extra outlets, quiet, and UPS.

Reviewer coverage of the C300 keeps landing on the same three notes. It's impressively compact and light for a 288Wh unitA2, its 10ms UPS switchover is genuinely rare at this size and priceA3, and the 140W USB-C makes it a real laptop charger rather than a glorified power bankA1.

Who Should Buy Which
Buy the SOLIX C300 if you…
- →You want the most capable charger in a small unit, the nightstand, desk, or campsite companion where an extra AC outlet, a 140W USB-C port, a quiet fan, and a five-year warranty each earn their place. The C300 gives you all of that, now for $269.99.
- →You want a tiny always-on backup for a router, modem, or mini-PC. The sub-10ms line-interactive switchoverA3 is the reason to pick this over the 300D for anything you can't afford to have reboot.
- →You're near it while it works, charging overnight or at a quiet desk, and the 25 dB noise floor matters more to you than the last eight-tenths of a pound.
Buy the Explorer 300D if you…
- →You carry it daily and every ounce counts. The 300D is under a pound lighter (8.27 lb against 9.1) and now about $91 cheaper too, so the lighter unit is also the less expensive one.
- →You specifically want Jackery's reach, the ability to buy it at Costco or Amazon and return it there painlessly if it arrives wrong. On a sub-$300 unit, that return counter is a real form of insurance.
- →You're drawn to the upright, speaker-style form factorB2 and you're charging phones, cameras, and a laptop rather than running anything through an AC outlet.
If neither fits
If you need to run an actual appliance, skip both. A full CPAP night wants about 320Wh and neither 288Wh box guarantees it; a fridge, a blackout, or a weekend of camping runs multiples past what either holds. These are device chargers for phones, laptops, cameras, and a CPAP for part of a night, not battery banks for the house. If your list includes a wall-powered appliance, buy a station two to three times this size and don't make a 288Wh unit do a job it was never built for.
The Bottom Line
Same 288Wh battery, same 3,000 cycles, now about $91 apart — and the Anker SOLIX C300 is the pricier one, but also the one with more outlets, the faster USB-C, the longer warranty, the quicker switchover, and the quieter fan. The Jackery Explorer 300D gives most of that up, but wins the two things a lot of buyers weigh first: it's under a pound lighter and about $91 cheaper.
It's a well-specced little unit that now asks a real premium over its lighter twin. If you want the extra outlets, the quiet, the longer warranty, or the line-interactive UPS, the C300 is worth the ~$91 and stays the pick. If you mostly want a 288Wh charger for the least money and don't need those, the Jackery now makes that case.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
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.
Why does the Anker C300 cost more if it has the same battery?
You're paying for capability, not capacity. Both hold 288Wh and both are rated for 3,000 cycles, so lifetime energy is identical at 864 kWh. The C300's roughly $91 premium ($269.99 against $179) buys three AC outlets to the Jackery's one, a 140W USB-C port against 100W, a five-year warranty against three, a faster UPS switchover, and a quieter fan, not more power or longer life. If you don't need those, the Jackery's lower price is the stronger argument.
Can either one run a CPAP all night?
Not with margin. A full eight-hour CPAP night draws roughly 320Wh, and both units hold 288Wh, so a humidified machine will likely outlast the battery before morning. For reliable overnight medical use, step up to a station with more headroom; these 288Wh chargers are better suited to a partial night or a machine with the humidifier off.
Which is quieter, the C300 or the 300D?
The Anker C300, clearly. It's rated at 25 dB against the Explorer 300D's 45 dB under load, roughly the difference between a whisper and a refrigerator's hum. If the unit will sit on a nightstand or a quiet desk while it charges, that 20 dB gap is the most noticeable difference between them.
Do these have real AC outlets, or are they USB-only?
Both have AC. The C300 carries three AC outlets, the Explorer 300D one, alongside USB-C and USB-A ports on each. They're small 288Wh units, so the AC outlets are for lamps, laptops, and small electronics rather than a fridge or a power tool, but the wall plugs are there, and the Anker gives you three of them to the Jackery's one.
