Head-to-head test
Goal Zero Sherpa 100AC vs Jackery Explorer 300
They're $9 apart but they're not the same tool: the only question that decides it is whether the battery has to fly — if it does, the airline-legal Sherpa 100AC; if it doesn't, the Explorer 300 is triple the capacity for barely more money.

Spec deltas
These two cost within $9 of each other and could not be more different. The Sherpa 100AC is a 94.7Wh travel battery that fits in a laptop bag; the Explorer 300 is a 293Wh camp station, roughly three times the battery and three times the continuous output at 300W to the Sherpa's 100W. Same price bracket, $259 against $250, completely different tools.
If you're choosing on price, the Explorer settles it. That $9 buys triple the capacity, and its stored energy costs $0.95 a watt-hour against the Sherpa's $2.64. A battery that's going to live at a campsite, on a desk, or in a trunk should be the one that gives you more of everything for barely more money.
The Sherpa earns its place in exactly one situation, and it's a real one. At 94.7Wh it slips under the 100Wh limit airlines put on lithium batteries, which the Explorer nearly triples, so it's the only one of these two you can carry onto a planeA1. Two pounds, a 100W USB-C port that refills a laptop and needs no wall brickA3, plus 15W wireless chargingA2. Fly for work? Buy it. Everyone else: the Explorer.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Measured as a way to store and deliver power, the Explorer isn't marginally cheaper: its energy costs $1.19 a lifetime kilowatt-hour against $5.28, roughly a quarter as much, for a sticker only $9 higher. The Sherpa's price is buying travel hardware, not battery.
Sherpa 100AC: 94.7Wh for $250; Explorer 300: 293Wh for $259Cost per watt-hour: $2.64 vs $0.95Sherpa rated for 500 cycles, Explorer for 800Lifetime energy: about 47 kWh vs 234 kWh; $5.28 vs $1.19 per lifetime kWh
Why it mattersAnyone shopping these as batteries — for a campsite, a desk, a trunk — is overpaying badly with the Sherpa; the Explorer is the value pick and it isn't close.
continuous output
For a traveler the whole comparison inverts. One of these is a 2-lb, airline-legal battery that tops up a laptop over a single 100W USB-C cable with no wall brickA3; the other is a 7-lb box that legally can't leave the ground. The extra 200Wh isn't a feature to someone boarding a plane — it's the exact thing that grounds it.
Sherpa 100AC: 94.7Wh, under the 100Wh airline limit, airline-approvedA1Explorer 300: 293WhSherpa is 2.1 lb with a 100W USB-C port that also recharges it, plus 15W wirelessA2A3Explorer is 7.1 lb and its USB-C caps at 60W
Why it mattersIf your use case includes airports, the value math is irrelevant: the Sherpa is the only eligible option, and it's the buy.
The gap isn't only how long each runs — it's what each can run at all. On a 150W blackout load the Explorer holds while the Sherpa, able to surge to 150W, drops to 100W and quits; a 400W tailgate load the Explorer at least starts and the Sherpa can't touch. Capacity never even gets a say.
Sherpa: 100W continuous, 150W surge; Explorer: 300W continuous, 500W surge8-hour-blackout 150W load: the Explorer sustains it; the Sherpa surges to 150W but drops back to its 100W rating and stallsTailgate 400W peak: the Explorer can start it on its 500W surge; the Sherpa can't start it at all
Why it mattersIf you need to run anything with a motor or a heating element, even briefly, the Sherpa's 100W ceiling rules it out before watt-hours matter — that buyer wants the Explorer, or something bigger.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: The one axis that flips the verdict: the 94.7Wh, 2.1-lb Sherpa is airline-legal and fits a laptop bag, while the 293Wh, 7.1-lb Explorer can't fly at all.
weight
This is the only spec that reverses the verdict, so start here. The Sherpa 100AC weighs 2.1 lb and holds 94.7Wh, deliberately under the 100Wh ceiling airlines put on lithium batteries, which is why it's filed as carry-on gear rather than a power stationA1A2. The Explorer 300 is 7.1 lb and 293Wh: more than three times the weight, and nearly three times over that airline limit. One rides in your laptop bag onto a plane; the other rides in your trunk to a campsite.
The Sherpa backs the travel story with the right ports. Its 100W USB-C both charges a laptop over one cable and refills the Sherpa itself with no separate wall brick, and there's 15W wireless charging on topA2A3. The Explorer's USB-C caps at 60W and it's a two-hands lift. If 'portable' for you means an airport and a seat-back tray, the Sherpa is the only one of these two that qualifies, and that's worth more than any watt-hour it gives up.
Lifetime Value
Selected because: Within $9 on price, the Explorer holds just over three times the capacity (293Wh vs 94.7Wh); if the battery isn't flying, that value gap decides it.
cost / lifetime kWh
The value table points one direction and doesn't waver. The Explorer holds a larger pack and is rated for more charge cycles, 800 to the Sherpa's 500, so both the price-per-watt-hour and the lifetime-cost columns land in its favor — the second by a wider margin than the first, because capacity and cycle life multiply. You are, in effect, paying the Sherpa a premium for being small and flightworthy.
That premium is worth real money to the right buyer and nothing to the wrong one. If the battery flies or lives in a bag, the travel engineering is the point and the gap is a fair trade. If it sits at a campsite, the same gap is just money left on the table. Nothing in this section rescues the Sherpa as a battery; it only reframes what you're paying for.
Your Life, Your Pick
Selected because: Neither is a house battery, but the Explorer's 300W inverter and 293Wh run small AC loads the Sherpa's 100W can't start, and it finishes light tasks the Sherpa falls short on.
Run these against real loads and the picture is honest: neither is a power station. The weekend-camping profile wants 2,100Wh, and the Sherpa covers about 4% of it, the Explorer about 12%. An 8-hour blackout at 1,645Wh is the same story a size larger. These are day-batteries — a phone, a laptop, a camera, a fan — not house batteries.
Where they part ways is the small stuff. The Explorer's 300W inverter starts and holds loads the Sherpa's 100W can't, even when its 293Wh can't run them long. And on a genuinely light task the Explorer simply finishes and the Sherpa doesn't: a 100Wh afternoon off-grid session leaves the Explorer 149Wh of headroom while the Sherpa comes up 20Wh short. The Explorer isn't a bigger Sherpa; it's the next category up.
What the Specs Don't Tell You
Selected because: Warranty ties at two years; the lone asterisk is a noise one — the Explorer lists a 36dB floor, the Sherpa lists nothing — and it barely bites at these sizes.
rated cycles
Two footnotes, one that matters. Warranty is a wash — both carry two years, so it can't break the tie. The noise line is subtler: the Explorer publishes a 36dB figure and the Sherpa publishes none. That isn't evidence the Sherpa is louder; it's that there's no number to hold it to, and the 36dB is a best-case 'as low as' floor anyway, not what you'll hear under load.
It barely matters here, and that's the useful part. Noise is a bedside spec — it decides CPAP and bedroom units — but at 94.7Wh and 293Wh neither of these runs a CPAP through the night, which is roughly a 320Wh ask. If silence next to your pillow is the goal, the quietest number on this page still isn't the answer; a larger, quiet-rated station is.

Keep the essentials running through a night without power
Neither unit
The Sherpa 100AC can start the 150W peak but not hold it — 150W of surge gets it going, then the 100W continuous rating takes over, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call. The Explorer 300 doesn't have the energy either — 249Wh usable against 1,645Wh, 1,396Wh short — so neither route works.

Conclusion
August 30, 2026
Verdict: the Explorer 300, on Power Score margin
The Explorer 300 wins for the overwhelming majority of buyers: $9 more than the Sherpa buys just over three times the capacity (293Wh vs 94.7Wh), three times the continuous output (300W vs 100W), and stored energy that costs a fraction as much over the unit's life. The one buyer who should flip to the Sherpa is the traveler — at 94.7Wh it's the only one of the two that clears the 100Wh airline limit and rides in a laptop bag, with a 100W USB-C port that charges a laptop and refills the unit with no wall brickA1A3. Not a close call on value; a genuine fork on use case.

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, Sherpa 100AC rates 3.3/5 (1st percentile of 22 Personal-class units), and Explorer 300 rates 3.6/5 (19th percentile of 22 Personal-class units).

Warranty: No Difference
Both units carry the same 2-year warranty, so coverage isn't a tiebreaker here.
Noise: one published number, and it barely applies
The Explorer 300 lists a 36dB floor; the Sherpa 100AC lists nothing. That's not proof the Sherpa runs louder — there's simply no figure to hold it to, and the 36dB is a best-case 'as low as' rating, not what you'll hear under load. It matters less than it looks: noise is a bedside spec, and at 94.7Wh and 293Wh neither of these lasts a night on a CPAP anyway. If a silent unit next to your pillow is the point, the number to chase is on a larger station, not either of these.

Brand trust
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
US-based company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.
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
Pioneer of the portable power market — strongest brand heritage. US-based company with ruggedized, weather-resistant designs (IP ratings vary by model). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
Goal Zero more or less invented this category and builds rugged, US-designed gear. But its once-premium support has slipped, with recent reports of long waits and its user forums shuttered. Don't pay the brand premium expecting white-glove service.
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
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
Jackery's real edge is availability — it's on the shelf at Costco, Home Depot, Best Buy, and Amazon. Direct warranty claims draw criticism, so buy from a retailer with a solid return window and let that be your warranty backstop.
Analyst note
Neither company's support desk is a reason to buy right now; both draw complaints, and both apps lag rivals. Choose on the hardware and your use case, then buy from a seller with a real return policy.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Goal Zero Sherpa 100AC
Field notes on the Sherpa read like a travel review, not a power-station review, because that's what it is. Reviewers highlight the airline-legal 94.7Wh, the 2-lb weight that disappears into a laptop bag, and best-in-class 15W wireless chargingA1A2. One hands-on test charged a laptop from 10% to 100% in about 90 minutes off the 100W USB-C port, using 45% of the Sherpa's own battery, and noted it refills from a USB-C source with no wall plugA3. The through-line: this is gear for someone who moves, and the people who like it are digital nomads and outdoor creativesA4.
“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.”

Jackery Explorer 300
The Explorer's field reports are the quiet-and-easy kind you'd expect from a small unit. One owner ran phones, a speaker, a fan, and an air mattress on a camping trip with no trouble and called it lightweight, quiet, and simple to use; another recharged everyday electronics and ran low-wattage gear for about two weeks before the battery ran downB3B4. One caveat on the paper trail: much of the glowing online coverage is actually about the newer Explorer 300 Plus, a different LFP unit we've set aside here, and this base model is older lithium-ion rated for 800 cycles, not the Plus's longer-lived packB0. Judged as a proven, no-drama 293Wh camp battery, though, it holds up.
“288Wh capacity with 300W output on LiFePO4 chemistry rated for 3,000+ cycles — over a decade of daily use, a major upgrade from the older lithium-ion Explorer 300 (500 cycles).”

Who Should Buy Which
Buy the Sherpa 100AC if you…
- →The frequent flyer. At 94.7Wh the Sherpa clears the 100Wh airline limitA1, so it's the power bank you actually carry onto the plane, not the Explorer.
- →The traveling photographer or laptop-first digital nomad: 2 lb in the bag, a 100W USB-C port that refills the laptop and the Sherpa itself with no wall brick, and 15W wireless chargingA2A3.
- →Anyone whose 'power problem' is a long flight or a coffee-shop workday rather than a campsite or an outage.
Buy the Explorer 300 if you…
- →Car campers and tailgaters who want the most battery and output per dollar and aren't flying with it — $9 over the Sherpa for triple the capacity and a 300W inverter.
- →The desk or nightstand backup buyer keeping phones, a laptop, a router, or a fan going for a few hours. Owners report it handles exactly that kind of small mixed load quietly and without fussB3B4.
- →Basically everyone who isn't getting on a plane with it.
If neither fits
Anyone planning to ride out a real blackout, run a CPAP all night, or power a fridge should skip both. These are a travel battery and a small camp battery: a single night's CPAP alone (about 320Wh) outlasts either, and an 8-hour blackout needs around 1,645Wh, which neither comes close to covering. That buyer wants a power station several times the size of either, not a choice between these two.
The Bottom Line
Buy the Explorer 300 unless you're getting on a plane. For $9 more than the Sherpa it gives you three times the battery, three times the output, and far cheaper energy over its whole life — the value case isn't close, and no 94.7Wh travel bank changes it for someone charging gear at a campsite or a desk.
The Sherpa 100AC wins one argument and wins it clean: it's the only one of the two that's airline-legal and rides in a laptop bag, with a 100W USB-C port to keep a laptop alive on the roadA1A3. Fly for work and that's the whole decision. Otherwise the Explorer is more of everything for $9 more — go get it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can I take the Jackery Explorer 300 on a plane?
No. Airlines cap spare lithium batteries at 100 watt-hours without special approval, and the Explorer 300's 293Wh is nearly triple that, so it can't be carried on or checked. The Goal Zero Sherpa 100AC was built to sit just under that ceiling at 94.7Wh, which is the main reason a traveler would choose it over the larger, cheaper-per-watt Explorer.
Is the Sherpa 100AC worth nearly as much as the Explorer 300 for a third of the battery?
Only if you fly with it or live out of a bag. As a battery the Sherpa is the expensive way to buy less: nearly the same price as the Explorer, a third of the capacity, and a higher cost per watt-hour to match. That $9 gap gets you the Explorer's triple capacity, so spend it unless the battery has to fly.
Which is quieter for a bedroom or a CPAP?
The Explorer 300 publishes a 36dB noise floor; the Sherpa 100AC publishes no figure at all, which isn't proof it's louder, only that there's nothing to hold it to. It's close to moot here, though: a typical CPAP night draws around 320Wh, more than either unit holds, so the machine stops mid-night regardless of how quiet the box is. For silent, all-night medical backup, size up to a larger station.
Can either one run a mini fridge or get me through a blackout?
Not really. The Sherpa's 100W inverter can't even start many fridges, and its roughly 80Wh of usable energy empties in about an hour of real AC use. The Explorer's 300W inverter (500W surge) will start and run a small fridge, but its 293Wh still empties in a few hours, and an 8-hour blackout needs around 1,645Wh, which neither comes close to covering.
