Head-to-head test
Anker SOLIX C200 DC vs BLUETTI Apex 300 + 2×B300K
One has no AC outlet, the other weighs 213.9 pounds, so this is settled before capacity or price: whether your power has to travel, and whether the gear you're running plugs into a wall.

Spec deltas
The numbers up front: the Anker SOLIX C200 DC is $140 and 4.2 lbs; the BLUETTI Apex 300 with two B300K batteries is $3,699 and 213.9 lbs. One rides in a backpack to a fishing boat. The other is a two-person lift you place once and never move again. Whatever brought you to this page, these two aren't competitors, they're answers to different questions.
The dividing line isn't capacity, it's the outlet. The C200 has no AC outlets at all; its 200W is a DC total across USB and 12V ports, so anything that ends in a wall plug, a fridge, a router, a TV, a coffee maker, never runs on it at any charge level. The Apex carries a real inverter behind 6 AC outlets and 8,294Wh, enough to keep a house's essentials alive through a blackout. So the first question isn't which is better; it's whether the gear you care about plugs into the wall.
That makes this a tie in the only sense that matters: neither is the better buy, because they aren't buys for the same person. If your power needs to travel and top up phones, laptops, a camera or a Starlink Mini, the $140 Anker is the whole answer and the BLUETTI is 213 pounds of overkill. If you need to keep a fridge and a router running through an outage, only the Apex can do it, and even then most people staring at both should buy neither and get a mid-size AC unit that splits the difference.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Typical price
That $0.13 only beats $0.24 if you actually pour tens of thousands of kilowatt-hours through the thing. Buy the $3,699 system to run a phone and a headlamp and the per-kWh advantage never arrives; you've paid about 26 times the Anker's price to touch a sliver of what 192Wh even demands.
Apex 300 + 2×B300K: $0.13 per lifetime kWh vs the SOLIX C200 DC's $0.24the Apex delivers 29,030 lifetime kWh against the C200's 576the Apex is $3,699 vs the C200's $140
Why it mattersIf your real need is a few hundred watt-hours, ignore 'cheaper to own' entirely; it's an accounting feature of capacity you'll never spend.
The C200's real ceiling isn't 192Wh, it's the outlet. A fridge, router, TV or coffee maker can't run on it at any state of charge, which is why it clears exactly one job, the 100Wh afternoon of phones and a speaker, while the Apex clears the household loads by simply owning an inverter behind 6 AC outlets.

Why it mattersIf anything you want to power ends in a wall plug, the Anker is out before capacity is discussed; if nothing does, the Apex's inverter is 213.9 lbs of dead weight.
weight
These sit at opposite ends of the single axis that decides a power station's life, which is where it can be. The Anker's whole value is that people take it placesA3A4; the Apex's whole value is that it never moves and holds 8,294Wh while not moving. Neither can do the other's job at any price.

Why it mattersAnswer 'does my power need to travel?' before comparing one more spec; that one question retires half this page.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: The gap that settles this fastest: 4.2 lbs you carry anywhere versus 213.9 lbs you install once.
weight
Start here, because it eliminates one of these for you in about a second. The C200 is 4.2 lbs, luggage; owners drop it in a bag and take it onto a fishing boat or a delivery routeA3A4. The Apex is 213.9 lbs, an appliance you dolly into a corner and leave, a two-person lift you perform exactly once. There's no scenario where the same person wants both weights. You either need to carry your power or you need it to stay put, and that alone sends you to one side of this page.
Your Life, Your Pick
Selected because: Across seven real-world loads the DC-only Anker clears just one; the rest need an AC outlet it doesn't have.
The scoreboard looks lopsided for the Apex, and it's measuring the wrong thing for the Anker. The C200 clears exactly one of the seven jobs here, the 100Wh afternoon of phones and a speaker, which it finishes at 61% used, and it loses most of the rest not on capacity but on the outlet: the fridge, router, TV and camp lights in those scenarios are wall-plug devices that never touch a DC-only unit. Read the losses correctly and they don't say the Anker is too small. They say the Anker was never in the scenario. The Apex wins them because it has an inverter and 8,294Wh; the Anker sits them out because it has neither an outlet nor any intention of running a house.
What the Specs Don't Tell You
Selected because: The make-or-break catches, no AC outlets on the Anker versus 213.9 lbs and a UPS mode on the Apex, point at opposite buyers.
rated cycles
The catches on this page belong to two different buyers, which is the tell that it's a mismatch. The Anker's is decisive and simple: no AC outlets at all, so nothing with a household plug runs on it, ever; the 200W is a USB-and-12V total, not an inverter rating. The Apex's catches are the opposite kind, the price of being big: 213.9 lbs of place-it-once weight, a 45dB floor under load where the Anker just sits silent with no fan to runA0A2, and, on the plus side, the only UPS mode of the two. None of these catches trade against each other, because they answer to different people. That's the whole comparison in one section.
Lifetime Value
Selected because: Why the Apex's lower cost-per-kWh is a trap for anyone who doesn't actually need 8,294Wh.
cost / lifetime kWh
By every rate, the big BLUETTI is the 'cheaper' unit: $0.45 a watt-hour to buy against the Anker's $0.73, and less still once you spread it over its lifetime. Every one of those rates is real, and every one is beside the point, because you don't pay a rate, you pay a total. The number that lands on your card is $140 or $3,699, and which of those is 'cheaper to own' depends entirely on whether you'd ever use the energy that makes the Apex's rate look good. For a phone-and-laptop buyer, the cheapest unit on this page by a mile is the one that costs $140.
Strengths & trade-offs
Anker SOLIX C200 DC
Strengths
- +Costs $3,559 less
- +Lighter by 209.7 lb
Trade-offs
- –Weaker inverter (-3,640W) limits appliance compatibility.
- –Sealed capacity — the Apex 300 + 2×B300K can add batteries to grow past 192Wh; this one can't.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the Apex 300 + 2×B300K's 6,000, so it wears out sooner.
BLUETTI Apex 300 + 2×B300K
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$3,559) than the SOLIX C200 DC.
- –Significantly heavier (+209.7 lbs), making it harder to move.
- –Very heavy unit that may be difficult for one person to lift.

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
Neither, and for mirror-image reasons. The camp lights and box fan in this weekend are wall-plug devices, so they never touch the outlet-less C200, and no watt figure changes that. And nobody's hauling a 213.9-lb Apex to a campsite. One can travel but can't run the gear; the other can run the gear but can't travel. A genuinely powered weekend means a mid-size unit with AC outlets you can still lift.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Apex 300 + 2×B300K
The Apex wins, but the interesting part is how the Anker loses. A CPAP with a heated humidifier is an AC machine, and the C200 has no AC outlet to give it. Even a low-draw 12V CPAP only gets about half a night: 163Wh usable against the 320Wh this scenario needs, roughly 51% covered. The Apex finishes with 6,730Wh untouched. Eighteen inches from your head, the spec that decides this isn't capacity, it's whether there's an outlet the machine can use at all.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Apex 300 + 2×B300K
The Apex, and it isn't close. A full van day here is 4,685Wh, fridge, lights, laptop, water pump, and the Apex spends about two-thirds of its usable energy to cover it, 2,365Wh still in reserve. The 192Wh Anker isn't merely short; it's the wrong instrument, since those are AC loads it has no outlet for. Daily draw like this means you're shopping installed systems, and the C200 is the phone-charger you bring along, not the thing running the van.

Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This row is here for the SOLIX C200 DC's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the SOLIX C200 DC finishes at 61% used, and the Apex 300 + 2×B300K barely notices it. For this job the Apex 300 + 2×B300K's extra capacity is dead weight, not headroom; take the SOLIX C200 DC at 4.2 lbs and leave the rest at home.

Conclusion
August 30, 2026
Verdict: the Apex 300 + 2×B300K, on Power Score margin
Call it a tie, because these solve different problems and no amount of spec-stacking turns them into rivals. The $140 Anker is a 4.2-lb DC battery for phones, laptops, cameras and a Starlink MiniA4A5; it has no AC outlets, so it clears exactly one of seven usage scenarios, the 100Wh afternoon of phones and a speaker, and is disqualified from the rest before capacity even matters. The $3,699 BLUETTI is a 213.9-lb installed system with 8,294Wh and a real inverter that runs a blackout with room to spare, but it never leaves its corner. Buy the Anker if your power travels and stays under a couple hundred watt-hours; buy the Apex only if you genuinely need whole-home-scale backup and can site 214 pounds permanently. Most people looking at both actually want something in between.

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 C200 DC rates 4.0/5 (43rd percentile of 22 Personal-class units), and Apex 300 + 2×B300K rates 3.4/5 (7th percentile of 29 Whole-Home / Off-Grid-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.
Apex 300 + 2×B300K: 213.9 lbs Is a Commitment
At 213.9 lbs across its boxes, no one piece is the whole problem — but this is hardware you site, not hardware you carry. Once it's set up, you won't want to move it. It's a semi-permanent appliance. Pick your spot.
Apex 300 + 2×B300K: 45dB Published
45dB is about as loud as a running refrigerator. It is BLUETTI's own rating rather than a reading on a shared bench — makers differ on whether they quote a best case or a figure under load, so treat it as a starting point rather than what you would hear at a bedside. For most people, fan noise around 45dB and up is where sleep starts to suffer.
SOLIX C200 DC: No AC Outlets At All
The SOLIX C200 DC's 200W 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 Apex 300 + 2×B300K carries a real inverter behind 6 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.
Fixed at 192Wh, And That's Fine
Sealed capacity isn't a knock on a 4.2-lb DC battery; it's the design. You size a phone-and-laptop unit to your need and carry it, you don't bolt extra batteries onto something you throw in a bag. The Apex expands because it's the opposite kind of product, a base you grow toward partial-home backup. Their growth paths don't compete any more than the rest of these specs do.
UPS Mode: Only One Even Qualifies
The Apex can sit between the wall and a desktop or router and flip to battery in no worse than 10ms when the grid drops. Read that as the spec-sheet ceiling it is rather than a measured result, but on paper it's quick enough to ride a PC through. The C200 can't do this, and not because it's slow: with no AC outlet, there's nothing to pass through. If ride-through is why you're shopping, only the Apex is in the room.
Warranty: 5 Years vs 3
The Apex 300 + 2×B300K is covered for 5 years against the SOLIX C200 DC's 3 years. The cheaper SOLIX C200 DC does buy more warranty per dollar (21.4 years per $1,000 against 1.4), but that is a statement about price, not about coverage — if a fault appears in year 4, only one of these is still covered. The Apex 300 + 2×B300K's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Apex 300 + 2×B300K is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. One caution reading years across different sizes: a cycle is 8,294Wh on the Apex 300 + 2×B300K and 192Wh on the SOLIX C200 DC, so count lifetime energy — roughly 49,766 kWh against 576 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.
SOLIX C200 DC: Noise Level Not Disclosed
The Apex 300 + 2×B300K publishes its noise level (45dB); the SOLIX C200 DC doesn't publish one. That isn't evidence the SOLIX C200 DC is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the Apex 300 + 2×B300K's 45dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the SOLIX C200 DC before deciding.

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
Parent brand trust from Anker's consumer electronics dominance. InfiniPower technology for long cycle life. Strong $/Wh value in the mid-size and larger units — the S2000, F2600 and C1000 are among the better buys per watt-hour in the catalog.
Worth knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
Analyst note
For once the brand question sits behind the hardware one; you're choosing a category before a maker. If support ends up deciding it, both have soft spots: Anker's once no-hassle service has drifted toward generic AI-agent replies, and BLUETTI's is the most inconsistent in the category, ranging from great to non-existent. If you do go BLUETTI, buy direct rather than through a reseller; it tends to produce better outcomes.

The SOLIX C200 DC is sealed at 192Wh, which is fine if that covers you. The Apex 300 + 2×B300K starts at 8,294Wh and can grow beyond it with BLUETTI expansion batteries — real headroom the SOLIX C200 DC doesn't have if your needs climb toward partial-home backup.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C200 DC
Owners like the C200 exactly where it's aimed. Several bought it specifically to run a Starlink Mini off-grid, on a fishing boat or at a remote site, and report flawless pass-through power for six-plus hours without an inverterA4A5A15. Continuous-duty use holds up better than people expect, from an eight-hour delivery shift keeping a phone and tablet topped upA3 to always-on power for a Linux SBCA6 to a 2.5-day iPad sessionA14. The recurring gripe isn't the battery, it's the box: no wall charger is included, and decent charge speed means supplying your own high-wattage USB-C brick, up to 140W, which blindsided at least one owner badly enough to send the unit backA2A7A10. One uncorroborated red flag worth noting and not overweighting: a single YouTube commenter reported three units in a row developing USB-C port failuresA12, one voice rather than a pattern, and our field record here leans on Amazon and Anker's own reviews with no Reddit corroborationA0.
“But in the specs it says the usb ports will shut off in 2 hours and that time can't be changed... I'm deciding between it and the Jackery 240D which keeps the ports on for 12 hours. But the Anker is lighter, cheaper and has a better warranty.”

The Apex 300 is a 2025-launch system, so long-term field data is thin, nothing past about six months and no cold-weather reports at allB0. What owners do document in this multi-battery configuration is charge desync: packs charging at different rates, one sitting at 100% while another is at 50%, which BLUETTI support has called normalB1B3. Solar buyers, the people this unit courts hardest, are its loudest critics, calling the 60V input ceiling 'misleading' and flagging a firmware bug that drops solar detection until you unplug and replugB8B9. Support runs hot and cold, from smooth help to multi-week silenceB4B11, and reviewers note that basic DC and USB ports sit behind a roughly $300 Hub D1 accessory rather than on the unit itselfB10B17. To its credit, hands-on reviewers ran household essentials for more than a full dayB16, found the fan even enough to sit beside a sleeping areaB14, and measured a low 20W idle drawB15. Just don't confuse it for portable; at 213.9 lbs it's a place-it-once installB12B13.
“For me the 240V output is great. I can stick it in the back of my PHEV and use the 240V output to charge at 3.3KW when I stop.”

- No wall charger is included, and getting decent charge speed means sourcing a high-wattage (18W+, ideally 140W PD3.1) USB-C charger yourself — a recurring source of either mild annoyance or, for one reviewer who lacked a compatible charger on hand, a full return-to-sender experience. [SOLIX C200 DC · 3 entries]
- Independently of Anker's own marketing, multiple owners specifically bought and use the C200 DC to run a Starlink Mini off-grid (boat, remote site), reporting flawless pass-through power and multi-hour runtime without an inverter. [SOLIX C200 DC · 3 entries]
- Sustained, continuous-duty use (an 8-hour delivery shift, always-on passthrough to a Linux SBC, a multi-day iPad session) holds up better than owners expected, with battery percentage staying higher than they anticipated. [SOLIX C200 DC · 3 entries]
- Despite Anker's "39% smaller than peers" marketing claim, real-world size/weight impressions are split — some owners find it genuinely pocketable, others notice real heft once it's actually loaded in a bag. [SOLIX C200 DC · 2 entries]
- When multiple Apex 300 units (as in this 2x-B300K configuration) are charged together, owners report state-of-charge sync problems and solar input capped far below the advertised rating, which Bluetti support has called 'normal' behavior. [Apex 300 + 2×B300K · 3 entries]
- Customer/RMA support experience is inconsistent — some owners report smooth help, others describe multi-week delays and unresponsive tickets. [Apex 300 + 2×B300K · 2 entries]
- The base unit's 60V solar input ceiling and a firmware bug that drops solar detection (requiring an unplug/replug) are the two most-cited technical gripes among solar-focused owners. [Apex 300 + 2×B300K · 2 entries]
- Because the Apex 300 ships with no built-in DC/USB ports, owners and reviewers alike flag the mandatory ~$300 Hub D1 accessory as an unexpected added cost. [Apex 300 + 2×B300K · 2 entries]
- Despite being marketed as 'portable,' the unit's weight (~38kg/85lb base alone, more with B300K batteries) leads multiple sources to describe it as effectively a stationary/semi-permanent installation rather than something carried around. [Apex 300 + 2×B300K · 2 entries]

“It's lightweight, easy to carry, and has enough power for phones, lights, a fan, and smaller devices... I like how quiet it is compared to larger units. My only complaint is I wish it included the wall charger instead of having to buy one separately.”

Who Should Buy Which
Buy the SOLIX C200 DC if you…
- →You power phones, tablets, a laptop or a camera away from the wall and want to actually carry the thing, 4.2 lbs into a backpack, a boat, a delivery routeA3A4.
- →You run a Starlink Mini or other USB and 12V gear off-grid; owners do exactly that for six-plus hours and rate it highlyA4A5.
- →You want silence and your loads are DC. No inverter, no fan, nothing to wake youA0A2. Just size to 192Wh up front, because that's the ceiling.
Buy the Apex 300 + 2×B300K if you…
- →You need genuine backup: a fridge, router and lights through an 8-hour blackout, with 5,405Wh left over and a UPS handoff rated no worse than 10ms so a desktop or router never blinks.
- →You're wiring a van, cabin or partial-home setup around 8,294Wh you can expand later, and you can give 213.9 lbs a permanent home.
- →You'd otherwise assemble an inverter, solar charger and battery bank separately; at least one owner priced that DIY route and the Apex came out similarB6.
If neither fits
If you pictured carrying something to a tailgate that still runs a blender and a TV, or a home battery that doesn't weigh as much as a grown adult, buy neither. The Anker can't power an AC appliance at all, and the BLUETTI can't come with you. What most people weighing these two actually want is the ground between them, a mid-size portable with real AC outlets that one person can still lift, a different class than either the $140 DC brick or the $3,699 install, and where this search usually should end.
The Bottom Line
The scoreboard says the Apex wins four scenarios outright, with two more going to neither unit, but that's the wrong way to read a mismatch. The Anker loses those rows on the outlet, not the battery: the fridge, TV and camp lights in them are wall-plug devices a DC-only unit was never going to run, while the single job it's built for, a 100Wh afternoon of phones and a speaker, it does at 4.2 lbs for $140. This was never a fight; it's a fork.
So don't crown a winner; answer a question. If your power travels and tops up small gear, the Anker is the entire answer and the BLUETTI is 213.9 lbs of overkill. If you must run a house through an outage, the Apex can, for $3,699 that stays in one spot. And if you're like most people who land on this comparison and wanted something between a pocket DC brick and a 213.9-lb install, close the tab and go price a mid-size portable with real AC outlets. That's the honest end of this page.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the Anker SOLIX C200 DC run a CPAP overnight?
Not reliably. A CPAP with a heated humidifier is an AC device, and the C200 has no AC outlet, so it can't run that kind at all. A low-draw 12V CPAP is within its wheelhouse, but 163Wh of usable energy against a typical 320Wh night leaves it about 157Wh short, roughly half the night. For dependable overnight CPAP you want an AC outlet and more capacity than that 320Wh, which points at the Apex or a mid-size unit, not this.
Why is the BLUETTI called 'cheaper to own' when it costs $3,699?
Because 'cheaper to own' is measured per kilowatt-hour of lifetime energy, not per purchase. The Apex delivers about 29,030 kWh over its life to the Anker's 576, so its price spreads to roughly half the cost per kWh. That's only a saving if you actually use that much energy. Need a few hundred watt-hours instead? The $140 Anker is far cheaper in the only way that reaches your wallet.
Does the Anker C200 DC have AC outlets, or can it run household appliances?
No AC outlets, and no household appliances. It's a DC-only unit; its 200W rating is a USB and 12V total with no inverter, so anything with a wall plug won't run on it at any wattage. Phones, laptops, cameras, USB and 12V gear are its world; a fridge, TV or coffee maker are not. If you need to power an appliance, that one fact rules it out.
Is the BLUETTI Apex 300 actually portable?
Not in any practical sense. At 213.9 lbs it's a two-person lift and a place-once install; reviewers describe it as effectively stationary. Think of it as an appliance you wire in, not a box you carry. If you need to move your power around, this is the wrong tool, which is exactly what the 4.2-lb Anker is for.
For van life, which one do I need?
Your daily draw decides it, and the split is clean. A built-out van pulling about 4,685Wh a day, fridge, lights, laptop, water pump, needs the Apex, which covers it with 2,365Wh to spare and can expand later. Those are AC loads the 192Wh Anker has no outlet for. But if your 'van life' is really phones, a fan and a Starlink Mini on DC, the 4.2-lb Anker is the smarter, lighter buy.
