Spec deltas
The Apex 300 holds 2,765Wh and costs $1,699. The Sherpa 100AC holds 94.7Wh and costs $250. Those aren't two answers to the same question, and the most useful thing this page can do is stop pretending they are.
Our load board runs six scenarios. The Apex wins five, both units fail the sixth, and the Sherpa's best showing on the whole board is the CPAP row, where it's still 240Wh short of a 320Wh requirement. Roughly a quarter of the way to morning. It isn't losing these events. It was never entered in them.
So here's the honest frame. The Apex 300 is an install-class battery: you choose where it goes, you plug the loads into it, and it stays there. The Sherpa 100AC is a 2.1-lb travel bank with a 100W AC outlet, and the one thing it does that no Apex does at any price is clear airline rules and fly with youB1. Buy on which of those two sentences describes your problem. If neither does, both of these are the wrong purchase, and finding that out here is worth the five minutes.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
weight
Nothing on the Apex 300's spec sheet competes with that, because the competition is regulatory rather than technical. The Apex weighs roughly forty Sherpas (83.8 ÷ 2.1) and holds nearly thirty times the energy, and both facts are equally irrelevant at a security checkpoint. The spec that settles this page isn't capacity. It's whether your trip has a boarding pass.
Sherpa 100AC capacity: 94.7WhReviewers describe it as sitting under the 100Wh FAA flight limit and airline-approvedB1Sherpa 100AC weight: 2.1 lbs against the Apex 300's 83.8 lbs
Why it mattersIf you fly with your power, stop comparing: only one of these two is legal in the overhead bin, and it isn't the one that wins every other row.
rated cycles
That buyer reaches the rating in about 1.4 years and then lives with a pack at roughly 80% of its original capacity. The Apex clears the same 500 cycles twelve times over on its way to 6,000 (6,000 ÷ 500). The $250 is not a durable good for the person who actually needs it daily. It's a consumable with a renewal date, and the person who charges it four times a year will never find that out.
Sherpa 100AC rated for 500 cycles, which the lifetime model puts at about 1.4 years of daily useOne reviewer took a laptop from 10% to 100% in 90 minutes and spent 45% of the Sherpa's battery doing itB3Apex 300 rated for 6,000 cycles, or about 16.4 years at the same daily use
Why it mattersDaily users should price in a replacement before they buy; if yours lives in a go-bag, ignore this entirely, because you'll never get near the cycle count.
continuous output
For a whole class of loads, giving the Sherpa a bigger battery would change nothing, because the inverter says no before the cells are asked. Motor loads are the sharp edge of this: fridges, compressors and power tools briefly pull 2-3x their rated wattage at startup, which is precisely what the Apex's 2x surge headroom (7,680W over 3,840W) exists to swallow.
Sherpa 100AC: 100W continuous rating, 150W surge ceilingApex 300: 3,840W continuous, 7,680W surgeTwo of the six scenarios (8-Hour Blackout, Tailgate Party) are decided by peak demand before capacity is consulted
Why it mattersIf anything you plug in has a motor in it, the Sherpa is disqualified on its rating alone, and no amount of extra capacity in that class fixes it.
This is the one row where the Apex's expansion matters more than its capacity does. BLUETTI expansion batteries turn that shortfall into a purchase order instead of a wall. The Sherpa is sealed at 95Wh, which isn't a flaw so much as a description of what a two-pound travel bank is, and it does mean full-time van power was never on the table for it.
Van Life Daily needs 4,685WhApex 300 usable figure: 2,350Wh after the flat 85% factor the load model applies to every unitApex 300 finishes 2,335Wh short; Sherpa 100AC finishes 4,605Wh short
Why it mattersFull-timers should budget for the Apex plus expansion at the outset rather than discovering the gap in month two.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Five of the six scenarios go to the Apex 300 and the sixth goes to neither, which reads better as a sizing chart than as a scoreboard.
Five wins and a mutual failure is a sizing chart, not a scoreboard. Three of those five are settled by capacity the Sherpa 100AC was never built to carry, and two by an inverter rating that declines the load before the battery is consulted. Reading this board as a defeat for the Sherpa gets the page backwards.
The board's real limitation is what it doesn't test. There's no row for fitting under the seat in front of you, and no row for going through an X-ray machine without a conversation, and those are the rows the Sherpa would win outright. If your power problem is one of the six described here, buy the Apex 300 and stop reading. If your problem isn't on the list at all, this board has nothing useful to say about your decision.
Portability & Form Factor
Selected because: 2.1 lbs against 83.8 lbs is the one axis where the Sherpa 100AC wins outright, and for some buyers it's the only axis that exists.
weight
The Apex 300 is the only unit here that requires a plan before it arrives. Reviewers who've actually lifted it split the difference honestly: one credits the handles and modular battery design with keeping it manageable, another says they can barely move it a few feet and couldn't get it onto a tableA6A8. Both readings are compatible. Good handles don't repeal 83.8 lbs.
Weight decides where these live, not how far they travel. The Apex is a place-it-once appliance, and its 2,400W of solar input tells the same story, because 2,400W is a roof or a ground array rather than something you unfold at a picnic table. The Sherpa 100AC's 60W input is the folding panel. Two different products wearing the same category name.
Lifetime Value
Selected because: 500 rated cycles against 6,000 changes what each of these costs to keep, not just what it costs to buy.
cost / lifetime kWh
The Sherpa 100AC will deliver 94.7Wh x 500 cycles across its entire rated life. The Apex 300 covers that in seventeen full charges of its own 2,764.8Wh, and it is rated for 6,000 of them. That's where ten cents against five dollars twenty-eight per lifetime kWh comes from, and once you've read it the arithmetic is finished.
The catch is that cost per kWh only measures the right thing if energy is what you're buying. Nobody purchases a 94.7Wh bank to store cheap electricity. They purchase something that disappears into a laptop bag with a wall outlet on the side of it, and no denominator captures that. Where the lifetime math does bite the Sherpa is the 500-cycle rating: at daily use that's about 1.4 years, so a unit that genuinely works for a living is a consumable. Used four times a year, it will comfortably outlast your interest in it.
What the Specs Don't Tell You
Selected because: Nine cards fire on this pair; most restate the size gap, and a couple carry information the size gap doesn't.
rated cycles
Nine cards fire on this pair and seven of them are the size gap wearing different hats. Two aren't. The Sherpa 100AC publishes no noise figure at all, which is not evidence that it's quiet, it's the absence of a number to hold it to, and the Apex 300's 45dB is the only published figure on the table. And the surge card quietly reframes the whole matchup, because a 100W continuous rating with a 150W ceiling rules out motor loads no matter how much battery sits behind it.
The app card cuts both ways, and it's worth saying so before you read it as a clean win. App control genuinely matters on a unit that lives in a basement bay, and it's also the Apex 300's most-complained-about surface: sluggish next to the EcoFlow and Anker apps, and prone to trouble immediately after a firmware updateA1A4A10. The Sherpa's missing app costs you nothing, since you check a 95Wh bank by looking at it.
Brand Trust
Selected because: Five years of BLUETTI warranty on a $1,699 unit is a longer relationship than two years of Goal Zero on a $250 one.
A five-year warranty is a five-year relationship, and on a $1,699 unit that deserves more thought than the sticker does. What we can say about the Apex 300 so far is that its early record is largely a firmware record: four separate owner reports of an update breaking something, from a unit stuck in Backup mode to Bluetooth dropping out of a Home Assistant integrationA1A2A3A4. The unit is new enough that this is simply the evidence that exists, not a verdict on the hardware.
Goal Zero's side of this is smaller in every direction. It's a US company in Salt Lake City with the longest heritage in the category, and it's asking you for $250 and two years rather than $1,699 and five. A commitment that short and that cheap is a bounded risk. If a $250 bank dies the year after its warranty ends you buy another one, which is not a sentence anybody says about the Apex 300.

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
Apex 300
A weekend that wants 2,100Wh is the one row that genuinely leans on the Apex 300. It finishes with 250Wh in hand, its thinnest margin anywhere on this board. The Sherpa 100AC ends up 2,020Wh short of the 2,100Wh the weekend asks for, which isn't undersizing so much as the wrong appliance for the trip.

8-Hour Blackout
Keep the essentials running through a night without power
Apex 300
Capacity never gets a vote here. The scenario peaks at 150W, which is exactly the Sherpa 100AC's surge ceiling and half again its 100W continuous rating: a figure an inverter can touch, not one it can hold. The Apex 300 carries the full 1,645Wh with 705Wh still in the tank. For outage buyers, this row is the entire argument.

SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Apex 300
This is the closest the Sherpa 100AC comes on the whole board, and it's still only 80Wh against the 320Wh a CPAP night asks for. A quarter of the way to morning, then nothing. The Apex 300 finishes the night on 14% of its usable capacity, so the question stops being whether it lasts and becomes where you put it. It publishes 45dB under load. Eighteen inches from your head is not the spot.

LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Apex 300
910Wh is a desk, not a laptop. The Sherpa 100AC holds 80Wh usable and finishes 830Wh short of it, which is the honest description of a 100W travel bank: one device at a time, done well. The Apex 300 covers the day with 1,440Wh spare, enough to cover the next one too.

Tailgate Party
Game day power for the crew
Apex 300
A 400W peak is four times the Sherpa 100AC's 100W continuous rating, so this never reaches the capacity question. The inverter declines first. The Apex 300 runs the tailgate on 670Wh and keeps 1,680Wh back, which is enough to do the whole thing twice more.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit finishes this day. Full-time van life here means 4,685Wh, and the Apex 300 comes up 2,335Wh short, near enough to its whole 2,350Wh usable tank that the honest answer is that you need two of them. The Sherpa 100AC is 4,605Wh short, which stopped being a shortfall and became a category. The tiebreak that matters: only the Apex takes expansion batteries, so only one of these two has a route to yes.

The Sherpa 100AC doesn't finish — 80Wh usable against the 100Wh this needs leaves it 20Wh short, about 81% of the scenario covered. The Apex 300 covers it with 2,250Wh to spare.

Conclusion
August 9, 2026
Verdict: the Apex 300, on Power Score margin
Take the Apex 300 if your problem is one that either of these could plausibly solve, because the Sherpa 100AC solves none of them. It clears zero of the six load scenarios, and on two of them its 100W continuous rating turns the load away before capacity is even consulted. The Apex covers five with room to spare and costs $0.10 per lifetime kWh against $5.28. Then there's the caveat the scoreboard hides: if what you actually need is 94.7Wh in a laptop bag that clears airline rulesB1, the Apex isn't a worse version of that, it's not a version of it at all, and the Sherpa wins that comparison by forfeit.
Today the Apex 300 is $1,499, $200 under its typical $1,699. The verdict weighs typical prices, not today's. Prices checked 1 day ago.

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, Apex 300 rates 5.0/5 (99th percentile of 26 Large-class units), and Sherpa 100AC rates 3.3/5 (1st 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.
83.8 lbs Is a Two-Person Decision
83.8 lbs is the weight at which 'portable' quietly becomes 'where does it live.' Pick the Apex 300's spot before it arrives, whether that's a basement corner, an RV bay or the bed of a truck, because you'll move it deliberately and not often. Note the direction of travel, too: adding expansion batteries makes the installation heavier, never lighter.
Apex 300: 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.
No App, and Almost No Reason for One
App control earns its keep on a unit you install somewhere and then stop looking at. You check the Sherpa 100AC's charge by glancing at the bank sitting next to you. Score this card for the Apex 300 if it's going to live in a basement or an RV bay, and score it zero if it's going to live in your carry-on.
Fixed at 95Wh, and That's the Design
Calling a 2.1-lb travel bank 'not expandable' is a bit like calling a bicycle 'not towable.' The Sherpa 100AC is sealed at 95Wh because that's what the form factor is for, and expansion hardware would fight the only thing it does better than the Apex 300, which is disappear into a bag. Read this card as a question about which class you're shopping rather than a mark against the Sherpa. If your answer is 'I might need more,' you were never in the 95Wh class to begin with.
Surge Power: Inverter Quality Indicator
The Apex 300 has a 2× surge-to-continuous ratio vs the Sherpa 100AC's 1.5×, and the higher absolute ceiling with it — 7,680W against 150W. At 2× it clears the 2× rule of thumb for absorbing motor startups — fridges, AC compressors and power tools briefly draw 2-3× their rated wattage. What decides whether a given motor starts is the ceiling, not the ratio: the Sherpa 100AC still surges to 150W, so check the startup draw of the heaviest thing you plan to run against that figure rather than assuming it trips.
Only the Apex 300 Lists a UPS Mode
The Apex 300 can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. Worth it for a router, a desktop PC, or a CPAP. The Sherpa 100AC's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Warranty: 5 Years vs 2
The Apex 300 is covered for 5 years against the Sherpa 100AC's 2 years. The cheaper Sherpa 100AC does buy more warranty per dollar (8 years per $1,000 against 2.9), but that is a statement about price, not about coverage — if a fault appears in year 3, only one of these is still covered. The Apex 300'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 is rated for 6,000 cycles vs 500. In real life: at daily use, that's 16.4 vs 1.4 years. At weekend use (twice a week), it's 58 vs 5 years. One caution reading years across different sizes: a cycle is 2,765Wh on the Apex 300 and 95Wh on the Sherpa 100AC, so count lifetime energy — roughly 16,589 kWh against 47 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.
Sherpa 100AC: Noise Level Not Disclosed
The Apex 300 publishes its noise level (45dB); the Sherpa 100AC doesn't publish one. That isn't evidence the Sherpa 100AC 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'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 Sherpa 100AC before deciding.

Brand trust
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
Support is the risk premium on a BLUETTI. It's email-first with China-timezone delays, and outcomes swing wide, from clean quick claims to weeks of back-and-forth and offers of a discount on a new unit in place of a repair. Buying direct rather than through a marketplace tends to land you on the better side of that spread.
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
Some of the best capacity per dollar in the category, and the widest catalogue in it: 15 to 20 models spanning budget banks, sodium-ion cold-weather units, balcony storage and vehicle solar hubs. The Apex 300 sits at the flagship-portable end of that range.
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.
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
Goal Zero is a US company in Salt Lake City, owned by NRG Energy, and for years that bought a genuinely premium support reputation. That argument has weakened: long waits and unanswered tickets are part of the picture now, and the official community forums were shuttered. On a $250 bank this matters less than it would on a whole-home unit.
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 category's original brand, with ruggedised IPX4 designs and a tight Yeti-Ready ecosystem of coolers, lights and vehicle kits. The Sherpa line is the travel end of that, and it's the part of the range with the least competition from cheaper rivals.
Worth knowing
Typically the priciest brand per watt-hour — though individual pairings vary, and on some pages the Yeti is the cheaper energy. Support quality has declined from its "premium" standard. Perceived as competitively stagnant vs. faster-innovating Chinese competitors. Reliability reports on newer models are concerning.
Analyst note
The support question scales with the invoice. With the Apex 300 you're asking the company with the least consistent service record in the category to stand behind $1,699 for five years, and that's a real premium hiding past the sticker price. With the Sherpa 100AC you're asking Goal Zero to stand behind $250 for two, which is a much smaller ask of a promise that has also lost some shine. Neither service desk is a reason to pick one of these units over the other. The size of the box settled that first.
Growth path
Apex 300
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 2,765Wh.
Accepts up to 2,400W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
Expansion batteries are BLUETTI-specific. You're investing in the BLUETTI ecosystem.
Sherpa 100AC
FIXED CAPACITYFixed at 95Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 60W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.

Analyst note
The Sherpa 100AC is sealed at 95Wh, which is fine if that covers you. The Apex 300 starts at 2,765Wh and can grow beyond it with BLUETTI expansion batteries — real headroom the Sherpa 100AC doesn't have if your needs climb toward partial-home backup.

One unit stuck in Backup mode after an update, another throwing Error 004 at 97% charge, a Home Assistant integration that started dropping its Bluetooth connection after the latest update, and an app that keeps offering an update it then insists isn't neededA1A2A3A4. Four separate reports pointing at the same surface, on a product whose headline feature is app-managed backup.
The physical reports are mixed in a way that reconciles easily. One reviewer credits the handles and modular battery design with making the weight manageable; another can hardly move it a few feet and couldn't lift it onto a tableA6A8. A third notes the fans stay comparatively tame under load, which is worth something on a unit rated at 45dBA5, and a fourth flags that the rubber bungs over the ports get annoying with oversized plugs and adaptorsA9. The app itself is described as functional but sluggish next to EcoFlow's and Anker'sA10.
One thing we can't resolve, and you should know about it: several reviewers describe the base unit as having no USB or DC ports on its face, with a paid add-on hub needed to get themA7A11, while the spec sheet we hold for this unit lists a 100W USB-C output. We haven't reconciled those two accounts, so don't buy the Apex 300 for its port panel until you've confirmed the exact configuration you're ordering.

Goal Zero Sherpa 100AC
The Sherpa 100AC's field record is thin and uniformly warm, which is roughly what a simple product earns: four entries, all from reviewers rather than long-term owners, all positiveB1B2B3B4. The specifics that recur are the travel ones. 94.7Wh under the airline limit with a real 100W AC outletB1, two pounds with 15W wireless charging built inB2, and a 100W USB-C port that took a laptop from 10% to 100% in 90 minutes while spending 45% of the packB3.
What's missing is any durability signal whatsoever. Nothing in the record speaks to how it holds up after a year of living in a bag, how the cells age, or what happens when something goes wrong. The framing throughout is great travel gadgetB4. Against a 500-cycle rating, that's the gap worth noticing: the praise is all about week one.
“A 94.7Wh power bank — under the 100Wh FAA flight limit, so it's airline-approved — with a 100W AC port for laptop chargers, camera cradles, or small lamps.”

Who Should Buy Which
Buy the Apex 300 if you…
- →You want the house to stay up through a working day without power. The Apex 300 covers the 1,645Wh eight-hour outage scenario with capacity left over, and it can act as a UPS so the router and the desktop never blink.
- →You're wiring a cabin, an RV bay or a garage where the unit sits permanently and the loads come to it, rather than the other way round.
- →Something you run has a motor in it. 3,840W continuous with 7,680W of surge headroom is what absorbs a compressor or a circular saw at startup.
- →You expect your draw to grow. Expansion batteries make 2,765Wh a floor rather than a ceiling, which is the only reason either unit survives the van-life scenario as a plan.
Buy the Sherpa 100AC if you…
- →You fly with a camera kit or a laptop and want a wall outlet in your bag when you land. At 94.7Wh it's under the carry-on ceiling and sold as airline-approvedB1.
- →Your day is one device at a time. A single laptop charge from 10% to 100% ran 90 minutes and cost 45% of the packB3, which is an honest picture of what 94.7Wh does.
- →You want the phone charging pad built into the same brick you're already carrying, at 15WB2, rather than another cable in the bag.
If neither fits
If your day looks like the van-life row at 4,685Wh, neither of these finishes it. You're shopping for a system rather than a box: the Apex plus expansion batteries, or two units run in parallel. And at the other end, if all you need is a phone and a headlamp topped up over a weekend, $250 for 94.7Wh is an expensive way to buy that. A plain USB-C power bank is the category you actually want, and nobody will be offended if you close this tab and go buy one.
The Bottom Line
Buy the Apex 300 if you're buying a power station. Seventeen of its charges equal the Sherpa 100AC's entire rated lifetime, it clears five of the six load scenarios with the thinnest margin still 250Wh, and the sixth defeats both units, though only the Apex has an expansion path out of that. The firmware reports are the real caveat on it, and they're a software problem on a new product rather than a reason to buy 94.7Wh instead.
Buy the Sherpa 100AC only if what you're solving is travel. Two pounds, a genuine AC outlet, and it flies. That's a real product with a real buyer, and that buyer's decision was made before they landed on this page. Everyone else: the Apex, and clear a spot for it before it shows up.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can I take the Sherpa 100AC on a plane?
Yes, and that's most of the point of it. At 94.7Wh it sits 5.3Wh under the 100Wh limit airlines apply to lithium batteries in carry-on, and it's sold as airline-approved. The Apex 300, at 2,765Wh and 83.8 lbs, is not going anywhere near a cabin.
What's the difference between the Sherpa 100AC and the Sherpa 100PD?
The AC in the name is the AC outlet. The Sherpa 100PD is the USB-C-only variant of the same 94.7Wh pack and carries no AC inverter at all, so it can't run a wall plug. If the 100W AC port is why you're here, check the suffix on the listing before you check out. The two names are one letter apart and only one of them has an outlet on it.
Can the Sherpa 100AC run a CPAP overnight?
No. Our CPAP scenario needs 320Wh and the Sherpa holds 94.7Wh, or about 80Wh once you apply the flat 85% usable factor the load model puts on every unit. That's roughly a quarter of the night. The Apex 300 does the same night on 14% of its usable capacity, with one caution attached: it's rated at 45dB under load, so put it across the room rather than beside the bed.
Is the Apex 300 actually portable?
Not in the way the word usually implies. At 83.8 lbs it's a deliberate two-person move rather than something you carry to a campsite, and reviewers who've handled one describe it as barely liftable alone. Treat it as an appliance you position once: a basement corner, an RV bay, the bed of a truck.
Which one do I want for a power outage?
The Apex 300, and it isn't close. The eight-hour outage scenario needs 1,645Wh with a 150W peak, and the Sherpa's 100W continuous rating stops it at that peak before capacity ever matters, while the Apex covers the load with 705Wh spare and can carry the router and PC through the cut as a UPS. The Sherpa 100AC's role in an outage is keeping a phone and a laptop topped up, which its 94.7Wh will do.
