Spec deltas
Line up the two spec sheets and the capacity row is identical: 288Wh on each, though the Jackery is rated for 4,000 charge cycles to the Anker's 3,000. Runtime lives in the battery, the capacities match, so this was never going to be decided by how long either one lasts on a charge.
Almost everything that isn't the battery favors the Anker. The SOLIX C300 lists three AC outlets where the Explorer 300D, a DC-only unit, has none, a five-year warranty against three, a UPS mode rated to switch within 10ms where the Jackery lists none, and a published 25 dB noise rating against the Jackery's 45 dB, each maker's own figure. What it doesn't do is cost less: it's $330 against the Jackery's $179, about $151 more.
The Jackery's answer to all of that is that it's 3.6 lb lighter, about $151 cheaper, rated for a thousand more cycles, and that it comes from the brand with the widest retail footprint, Costco and Amazon included, where a return is a counter visit. Those are real. For many buyers the verdict is the Anker β it does more, with AC outlets, a UPS mode, a longer warranty, and a lower published noise figure β but it asks a ~$151 premium and gives up weight, so the call is a close one.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
rated cycles
The warranty doesn't rescue it. The Anker is covered for five years against three, but its higher price still works out to more per covered year than the Jackery's, and per lifetime kWh the Jackery costs less than half as much ($0.16 against $0.38). Every line of the cost math runs the Jackery's way.
the C300 holds 288Wh and costs $330the Explorer 300D holds 288Wh and costs $179the C300 is rated for 3,000 charge cycles, the Explorer 300D for 4,000
Why it mattersSo the usual instinct half-holds here: the pricier station is the Anker, and it is the better-covered, better-specced one β but you pay about $151 more up front, and whether that's worth it comes down to needing the outlets, the lower noise rating, and the UPS.
That's a category difference, not a rounding error: the C300 lists a UPS mode rated at 10ms or less, and the 300D lists none, so anything plugged into it rides an outage only as far as your reaction time. Sitting under a desk guarding a router or a mini-PC, the C300 is the one built to carry the load through a flicker without a reboot.
the C300 has three AC outlets and a top USB-C port of 140Wthe Explorer 300D is DC-only, with no AC outletthe C300 is rated to switch to battery within 10ms; the 300D lists no UPS mode
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 USB charger with no outlet at all.
Fan noise matters most under load, exactly when you're fast-charging a laptop off that 140W port or topping up overnight. The Anker's published figure is the lower one, but without a like-for-like test the gap is a reason to listen before you buy, not a measured result.
the C300 is rated 25 dBJackery publishes 45 dB for the Explorer 300Dboth are small 288Wh chargers meant to sit close to you
Why it mattersIf this charges your phone two feet from your pillow, weight the Anker's lower published rating, but hear both fans before letting noise settle anything.
The specific dimensions that decide these two units β everything else is a tie.
Lifetime Value
Selected because: The money case lives here: the cheaper Jackery also delivers more lifetime energy, while the Anker carries the longer warranty.
cost / lifetime kWh
This table usually breaks a tie; here it runs one way. Both batteries store 288Wh, but the Jackery is rated for 4,000 cycles to the Anker's 3,000, so it delivers 1,152 kWh over its life against the C300's 864. It also charges you less to get there, $179 against $330, so its cost per lifetime kWh comes in at less than half the Anker's ($0.16 against $0.38). More energy for a smaller sticker, and both are the Jackery's.
The warranty is the one place the Anker pushes back. It covers the C300 for five years, Jackery covers the 300D for three, but at the C300's higher price that longer coverage still costs a little more per covered year than the Jackery's. So the Jackery is cheaper to buy, cheaper per lifetime kWh, and marginally cheaper per warranted year; what the Anker's extra money buys is the five-year term itself and the AC side of the spec sheet.
Portability & Form Factor
Selected because: The Jackery's clearest physical win (weight) is here; voice it honestly, then price it against what it costs.
weight
Give the Jackery its due, because this row is clearly its. The Explorer 300D weighs 5.5 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 3.6 lb difference is genuine.
It isn't the whole of the Jackery's case, either β it pairs that lighter body with the lower price, about $151 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 lighter. The Jackery gets there partly by leaving out the inverter, so weigh the C300's three AC outlets and longer warranty against both.
What the Specs Don't Tell You
Selected because: Five cards fire: noise, AC outlets, UPS, warranty and cycle life; four point the Anker's way, and cycle life is the Jackery's.
rated cycles
Five gotcha cards fire on this pairing, and the Anker takes four. It publishes the lower noise figure (25 dB versus 45, each maker's own number), it's the only one with AC outlets, it's the only one with a UPS mode (rated within 10ms), and it's warrantied longer (five years versus three). The fifth, cycle life, goes to the Jackery: 4,000 cycles against 3,000, about 11 years of daily use against 8.2. Together the Anker's four are its real case, since the price row goes to the Jackery β capability the cheaper unit simply doesn't match.
The switchover card is the one worth a second look. The C300 lists a UPS mode rated at 10ms or less and the 300D lists none, a real 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 rates about 4.5 stars on iOS, while Jackery's sit at the bottom of the category. Jackery brings distribution: Costco, Home Depot, Best Buy, Amazon β plus the lower price. For a purchase this size, 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 leads on both price and reach β the Anker's counter is its stronger app, its longer warranty, and its fuller spec sheet.

Conclusion
October 14, 2026
Verdict: the Anker SOLIX C300
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. From there the Anker SOLIX C300 wins the spec sheet: three AC outlets to the Jackery's none, a five-year warranty instead of three, a UPS mode rated to switch within 10ms where the Explorer 300D lists none, and a published 25 dB against the Explorer 300D's 45 dB, though each maker publishes its figure its own way. The catch is price β the C300 costs about $151 more ($330 against $179), so it's the premium pick, not the value one. It's still more charger, but the Jackery's lower price and longer cycle rating make it the cheaper unit to own per lifetime kWh and per covered year, so you're paying up front for the capability. Take the C300 if you want the AC outlets, the lower noise rating, and the UPS; take the Jackery if everything you charge runs on USB and the lower price and lighter weight matter more.

Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, SOLIX C300 rates 4.3/5 (58th percentile of 25 Personal-class units), and Explorer 300D rates 4.8/5 (88th percentile of 25 Personal-class units).
How the class ranking is computed βTest Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
25 dB versus 45 dB
The C300 is rated 25 dB; Jackery publishes 45 dB for the Explorer 300D. Each maker measures its own way, so the 20 dB spread on paper is not a like-for-like gap. On a unit small enough to live on a nightstand, the lower published figure is worth weighting, but hear the fan before you let it decide whether the thing wakes you at 2 a.m. while it tops off your phone.
Explorer 300D: No AC Outlets At All
The Explorer 300D's 300W is a DC port total β USB and 12V β 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 SOLIX C300 carries a real inverter behind 3 AC outlets, so it plays in both worlds. Decide which side of that line your gear lives on before weighing anything else on this page.
A UPS mode on one side only
Only the C300 lists a UPS mode: it is rated to hand off to battery within 10ms when the grid drops. The 300D's spec sheet lists none, so anything plugged into it rides an outage only as far as your reaction time. For charging phones it makes no difference. For a desk-side router or mini-PC that can't take a reboot, the C300 is the one built to ride through a flicker without dropping the load.
Warranty: 5 Years vs 3
The SOLIX C300 is covered for 5 years against the Explorer 300D's 3 years. An underrated factor if you're keeping this unit for years.
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 β it drops to ~80% of 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 β 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. A couple of older models still ship NMC chemistry with a shorter rated life, so check the cycle rating on the specific unit; this one is rated for 4,000 cycles.
Analyst note
Two different bets for a small 288Wh charger. Anker gives you the better app, the longer warranty, and the fuller spec sheet; Jackery gives you the lower price, about $151 less, and the store you can walk the unit back into if it arrives wrong. The Anker's capability edge is real, but it isn't the cheaper bet, so the choice comes down to whether you need the extra outlets, quiet, and UPS.

Who Should Buy Which
Buy the SOLIX C300 if youβ¦
- βYou want the most capable charger in a small unit, the nightstand, desk, or campsite companion where AC outlets, a 140W USB-C port, a lower published noise rating, and a five-year warranty each earn their place. The C300 gives you all of that for $330.
- βYou want a tiny always-on backup for a router, modem, or mini-PC. The UPS mode, rated to switch within 10msA3, is the reason to pick this over the 300D, which lists no UPS mode, for anything you can't afford to have reboot.
- βYou're near it while it works, charging overnight or at a quiet desk, and the published 25 dB rating matters more to you than 3.6 lb of extra weight.
Buy the Explorer 300D if youβ¦
- βYou carry it daily and every ounce counts. The 300D is 3.6 lb lighter (5.5 lb against 9.1) and about $151 cheaper too, so the lighter unit is also the less expensive one.
- βYou specifically want Jackery's reach, a brand stocked at Costco, Home Depot, Best Buy and Amazon, so you can buy where a return is easy if it arrives wrong. On a unit this small, that return counter is a real form of insurance.
- βYou'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, which the 300D doesn't have.
If neither fits
If you need to run an actual appliance, skip both. A full CPAP night wants about 320Wh and neither 288Wh box covers it, each coming up about 75Wh short; 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, size a station to that load (the eight-hour blackout we model needs 1,645Wh) and don't make a 288Wh unit do a job it was never built for.
The Bottom Line
Same 288Wh capacity, about $151 apart β and the Anker SOLIX C300 is the pricier one, but also the one with AC outlets, the longer warranty, a UPS mode, and the lower published noise figure. The Jackery Explorer 300D gives most of that up, but wins the things a lot of buyers weigh first: it's 3.6 lb lighter, about $151 cheaper, and rated for 4,000 cycles to the C300's 3,000.
It's a well-specced little unit that asks a real premium over its lighter rival. If you want AC outlets, the lower noise rating, the longer warranty, or the UPS mode, the C300 is worth the ~$151 and stays the pick. If you mostly want a 288Wh USB charger for the least money and don't need those, the Jackery 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 β 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.
Why does the Anker C300 cost more if it has the same battery?
You're paying for capability, not capacity. Both hold 288Wh, and the Jackery is actually rated for more cycles, 4,000 to 3,000, so it delivers more lifetime energy (1,152 kWh against 864 kWh). The C300's roughly $151 premium ($330 against $179) buys three AC outlets to the Jackery's none, a five-year warranty against three, a UPS mode the Jackery doesn't list, and a lower published noise rating, 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?
No. A full eight-hour CPAP night draws roughly 320Wh, and each 288Wh unit has about 245Wh usable, so both come up about 75Wh short, covering roughly 76% of the night. For reliable overnight medical use, step up to a station with more headroom; these 288Wh chargers are better suited to a partial night.
Which is quieter, the C300 or the 300D?
On paper, the Anker C300. It's rated at 25 dB against the Explorer 300D's published 45 dB, but each maker publishes its figure its own way, so that 20 dB spread isn't a like-for-like measurement. If the unit will sit on a nightstand or a quiet desk while it charges, the lower published figure is worth weighting; hear both before treating it as settled.
Do these have real AC outlets, or are they USB-only?
Only the Anker has AC. The C300 carries three AC outlets behind a real inverter; the Explorer 300D is DC-only, with USB-C and USB-A ports and no AC outlet at all. They're small 288Wh units, so the C300's AC outlets are for lamps, laptops, and small electronics rather than a fridge or a power tool, but the wall plugs are there; on the Jackery, anything with a wall plug never plugs in.
