Spec deltas
The BLUETTI EB3A (268Wh) and Goal Zero Sherpa 100AC (95Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? We'd buy the EB3A.
The EB3A holds 173Wh more than the Sherpa 100AC — about 2 hours on a fridge against 1 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the EB3A if your primary use is afternoon off-grid. Go with the Sherpa 100AC if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the EB3A works out to about $0.33/kWh against the Sherpa 100AC's $5.28, a gap that compounds in the EB3A's favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
BLUETTI EB3A
At 600W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 10.1 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Costs $30.9 less
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
- +Rated for 2,500 charge cycles — much longer battery lifespan
Trade-offs
- –No major technical downsides compared to rival.
Goal Zero Sherpa 100AC
At 100W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 2.1 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Lighter by 8 lb
Trade-offs
- –Lacks smartphone app control for remote monitoring.
- –Shorter-lived battery — rated for 500 charge cycles vs the EB3A's 2,500, so it wears out sooner.

Scenario verdicts
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 unit covers this scenario's 2,100Wh: the EB3A comes up 1,872Wh short (about 11% covered), the Sherpa 100AC 2,020Wh (4%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
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 EB3A doesn't have the energy either — 228Wh usable against 1,645Wh, 1,417Wh short — so neither route works.

Neither unit
Neither unit covers this scenario's 320Wh: the EB3A comes up 92Wh short (about 71% covered), the Sherpa 100AC 240Wh (25%). On a CPAP that is not a shorter night — the machine stops when the battery does, partway through it. Neither is a bedside backup at this size.

Neither unit
The Sherpa 100AC can't run the 400W peak at all — 150W is the most its inverter will pass even momentarily, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call. The EB3A doesn't have the energy either — 228Wh usable against 670Wh, 442Wh short — so neither route works.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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, EB3A rates 3.8/5 (29th percentile of 22 Personal-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.
EB3A: 50dB Published
50dB is about as loud as moderate rainfall. 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.
Sherpa 100AC: No App Control
Without app control, you have to physically walk to the Sherpa 100AC to check battery level, adjust settings, or monitor power draw. The EB3A lets you do all that from your phone, including getting low-battery alerts.
Surge Power: Inverter Quality Indicator
The EB3A has a 2× surge-to-continuous ratio vs the Sherpa 100AC's 1.5×, and the higher absolute ceiling with it — 1,200W 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 EB3A Lists a UPS Mode
The EB3A can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤30ms — a transfer this long is one many desktops will NOT ride through, so plan on reboots for sensitive gear. Worth it for a router or a modem — not a CPAP: at 228Wh usable it can bridge the flicker but cannot run the night. 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: No Difference
Both units carry the same 2-year warranty, so coverage isn't a tiebreaker here.
Battery Lifespan in Real Years
The EB3A is rated for 2,500 cycles vs 500. In real life: at daily use, that's 6.8 vs 1.4 years. At weekend use (twice a week), it's 24 vs 5 years. One caution reading years across different sizes: a cycle is 268Wh on the EB3A and 95Wh on the Sherpa 100AC, so count lifetime energy — roughly 670 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 EB3A publishes its noise level (50dB); 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 EB3A's 50dB 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
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.
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
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
Goal Zero positions itself as a premium brand with stronger support infrastructure, while BLUETTI competes on value. The question is whether the Goal Zero ecosystem and support premium is worth it for your use case.
Growth path
EB3A
FIXED CAPACITYFixed at 268Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
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.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the EB3A gives you the larger ceiling); you can't add to either later.
The Bottom Line
The full picture comes down to this. The EB3A edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Sherpa 100AC wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the EB3A nor the Sherpa 100AC feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. Prices on portable power stations fluctuate frequently. Both BLUETTI and Goal Zero discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
"2,500 vs 500 cycles" — what does that actually mean for me?
In real years: the EB3A (2,500 cycles) lasts 6.8 years at daily use, 24 years at weekend use (twice a week), or 104 years at twice-monthly camping trips. The Sherpa 100AC (500 cycles): 1.4 years daily, 5 years weekends, or 21 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 268Wh unit becomes a ~214Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Can I use the EB3A as a home UPS to protect my electronics during blackouts?
Yes. The EB3A has UPS mode with true 0ms switchover (double-conversion). Even hospital-grade equipment won't notice. Plug in your desktop PC, router, NAS, or CPAP machine and it switches to battery seamlessly when the grid drops. The Sherpa 100AC does not have this feature. Without UPS, a blackout means: your PC reboots (potentially corrupting unsaved work), your NAS may corrupt its drive array, your CPAP alarms and wakes you up, and your security cameras go dark until you manually switch them over. If always-on power protection matters, this is a dealbreaker advantage for the EB3A.
Is BLUETTI or Goal Zero more reliable for long-term ownership?
Both brands have strengths and trade-offs. BLUETTI: 2-6 years depending on model (up to 10 years on home backup systems). Response times vary significantly. Some reports of units being deemed unrepairable with no parts available for older models. Goal Zero: 5 years on LFP models, 2 years on older NMC models. Battery must be charged within 7 days of purchase and every 6 months to maintain warranty (strict). Product reliability concerns have increased — repeat "Battery Fault" errors reported even on newer Yeti Pro 4000. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Bottom line: should I buy the EB3A or the Sherpa 100AC?
We'd buy the EB3A. Cheaper and more capable. That combination is rare. The Sherpa 100AC doesn't offer a compelling reason to spend more unless you specifically need a feature unique to the Goal Zero ecosystem (expansion batteries, app integrations). Otherwise, clear call.
