BLUETTI EB3A vs DJI Power 500
The Power 500 wins every number on this page that involves energy, so the EB3A's case comes down to six pounds and a 12V socket, which is a real case for exactly one kind of buyer and nobody else.

Spec deltas
BLUETTI's store has had the EB3A sold out since July 2026, so this page shows it no price. The Power 500 brings 244Wh more battery, 400W more continuous output and 1,500 more rated charge cycles. It is the buy. On any number that involves energy it is not close.
The EB3A's case is physical and narrow. It weighs 10.1 lbs against 16.1, the difference between a unit you forget you are carrying and one you set down to open a gate, and its record carries a 12V car outlet that the Power 500's record does not carry at all. A 12V fridge or a tyre inflator plugs straight into one and needs a workaround on the other. If that is your list, the EB3A still fits it, though any unit you find now is leftover stock. BLUETTI's Elite 30 V2 is the live unit in that size.
What ends the EB3A for anything resembling standby duty is its own field file. Owners report false overload shutdowns under light 40 to 60W loads in UPS mode, from 2022 through 2024, unfixed by firmwareA5A6A7A8. The Power 500's record is thin by comparison, four review-site entries and no long-term ownersB0, but nothing in it is that.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The capacity miss is the smaller half of it. The failures owners document cluster at exactly the 40 to 60W band a CPAP draws, in exactly the UPS mode a bedside unit sits in, across three years and a firmware update that did not helpA5A6A7A8. Running dry at hour five is an inconvenience. A false overload two hours into the night is a different category of problemA7, and no sticker gap covers it.
EB3A: 268Wh nameplate, 228Wh of working energy after the flat 85% usable derate applied to every unit hereThe overnight CPAP profile needs 320Wh, which is eight hours at the 40W it assumesOne tester ran a CPAP about six hours on a full EB3A chargeA17Power 500: 435Wh working, finishing the same night with 115Wh spare
Why it mattersIf this is going next to a bed to run a CPAP, the EB3A is off the list at any price, because the Power 500 is the only one of the two that gets through the night.
rated cycles
Fifteen cents per lifetime kilowatt-hour on the Power 500, and the EB3A has no live price to set beside it. Three times the lifetime energy settles it on its own: the only buyer who comes out ahead on the EB3A is one who genuinely will not cycle it much.
EB3A: 2,500 rated cycles at 268Wh, 670 kWh of lifetime energyPower 500: 4,000 rated cycles at 512Wh, 2,048 kWh of lifetime energyPower 500: $299; the EB3A is no longer sold by BLUETTI
Why it mattersAnyone who will reach for this weekly rather than twice a summer is buying the battery that lasts when they buy the Power 500.
continuous output
On the ratio the EB3A genuinely wins, and the ratio is what absorbs a compressor's startup. But a ratio is not a wattage. Anything rated between the EB3A's 600W and the Power 500's 1,000W sits inside one unit's continuous rating and outside the other's, which covers most microwaves, most kettles and a lot of corded tools. The Power 500's missing peak figure is a hole in the documentation rather than a hard wall, and the one reviewer who pushed it got 1,500W out of it brieflyB3.
EB3A: 600W continuous, 1,200W published peak, a 2x ratioPower 500: 1,000W continuous, and its record publishes no peak above that figureOne reviewer measured the Power 500 holding a 905W load and briefly riding a 1,500W spike past its ratingB3
Why it mattersChoose on the ratio if your load is a small motor rated comfortably under 600W. Choose on the continuous rating if anything you plug in draws more than that, and it is the Power 500 that wins there.
solar input
The catch is that the Power 500's 300W is a figure you have to buy your way to. There is no built-in charge controller, the adapter is proprietary, it is not in the boxB4, and this page carries no price for it. The EB3A's 200W needs a panel and nothing else.
EB3A: 200W solar ceiling into 268WhPower 500: 300W solar ceiling into 512WhDJI's record carries no built-in solar charge controller, so its solar input runs through a separate proprietary adapterOne reviewer noted the Power 500 ships with only a wall plug, no solar or car-charging cablesB4
Why it mattersIf solar is the main charging plan rather than a backup, price DJI's adapter and check what it actually passes before you compare stickers. If a wall outlet is your charger, ignore all of it.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Capacity decides this pair, and after the flat 85% usable derate the working figures are 228Wh against 435Wh.
continuous output
The flat 85% derate applied to every unit here turns 268Wh into 228Wh of working energy and 512Wh into 435Wh. That 207Wh difference is the page. It is the difference between a unit that finishes the 320Wh overnight profile with 115Wh in hand and one that stops 92Wh short, and between covering 65% of a tailgate list and 34% of it.
Refill speed does not rescue the smaller pack either. One tester filled the EB3A from a household outlet in just over four hoursA17, and the Power 500's larger battery comes with a larger solar ceiling to match it, 300W against 200W, so choosing the bigger unit does not buy you a longer wait. The runtime argument left for the EB3A is that it is enough, and for an afternoon of laptop, lights and a speaker it is: 44% used against the Power 500's 23%, both comfortably done.
Lifetime Value
Selected because: One of these is rated for 670 kWh over its life and the other for 2,048 kWh, which reorders which one is actually the better battery.
A cycle is not a unit of value. Energy is. The EB3A spends two of its cycles to move what the Power 500 moves in one, which is how a 1,500-cycle gap on paper becomes a three-to-one gap in lifetime energy. Cycled daily, the Power 500's rating stretches to 11 years against the EB3A's 6.8, and the warranty follows the same direction: up to five years for the Power 500, tied to buying from DJI's own store, against a flat two.
Nobody buys a 268Wh unit planning to cycle it daily for years, and that is the honest limit of this section. If it is the box you throw in the car four times a summer, both of these outlast your interest in them, and the lighter one is the easier case to make. The lifetime figures start mattering the moment this becomes the thing you reach for every week.
What the Specs Don't Tell You
Selected because: Both carry documented catches: the EB3A's fan and light-load UPS behaviour, and a Power 500 record that publishes no peak above its 1,000W continuous rating.
rated cycles
The EB3A's two documented problems are the two that matter most in a bedroom. Owners consistently report the fan cycling at idle, roughly every 20 minutes even at full charge with the AC input plugged inA3, with a buzz that arrives ahead of itA4 and a wobble one owner traced to an unbalanced fanA1. Worse, the light-load UPS overload pattern runs from 2022 to 2024 across the maker's own forum, a DIY solar forum and a retailer's review comments, at 40 to 60W, with a firmware update that changed nothingA0A5A6A7. One review states flatly that there is no true UPS here and puts the real interruption at one to two secondsA15. Our record still carries the rated 30ms class for it, that disagreement is unresolved, and an unresolved disagreement is itself the answer for anyone shopping for standby power.
The Power 500's catch is a documentation gap rather than a complaint, and it deserves saying out loud: its record publishes no peak above 1,000W, so its motor-starting behaviour is unquantified rather than proven bad. Add no built-in solar charge controller, a proprietary adapter for the solar input, and a box that ships with only a wall plugB4, and the shape of what you are buying is clear enough. It is the better battery with fewer answers attached.
Portability & Form Factor
Selected because: 10.1 lbs against 16.1, plus a 12V car socket on one record and none on the other. The EB3A's whole case lives here.
weight
Six pounds is the EB3A's entire argument and it is a real one. 10.1 lbs is a one-handed carry you stop noticing. 16.1 lbs is the weight you set down to open the tailgate and then pick back up. Neither is a two-person lift, so this is not a basement-stairs question. It is a how-far-are-you-walking question, and the answer differs for a kayak trip and a garage shelf.
The socket is the sharper point. The EB3A's record carries a 12V car outlet and the Power 500's carries none, so a 12V fridge, a tyre inflator or a 12V fan runs natively on one and needs an AC adapter and inverter losses on the other. Running the other way, the Power 500 carries two 100W USB-C ports against the EB3A's one, which decides it if a laptop and a camera battery both want fast charging at the same time. Pick by the cables you already own.
Brand Trust
Selected because: Two years of cover against up to five, and two opposite support stories behind them.
Up to five years against two is the part you can hold someone to, with one condition attached: the five is DJI's maximum, advertised for units bought from DJI's own store. Buy the Power 500 through a marketplace reseller and check what term actually comes with it.
The support stories behind those terms run in opposite directions. BLUETTI has the longer history in this category, the wider catalogue and the better-rated app, along with the least predictable support desk in the space, and two owners here describe tickets going unanswered and firmware advice that made things worse during exactly the UPS troubleshooting this unit needsA9A10. DJI has almost no power-station history and the repair network of a company that has been fixing expensive drones for years. Neither is a guarantee. One of them has a stated five-year reason to pick up the phone.

Conclusion
November 1, 2026
Verdict: the Power 500, on Power Score margin
Buy the Power 500, at $299. BLUETTI no longer sells the EB3A, so this page shows it no price, and the Power 500 would win a live matchup anyway. It holds 244Wh more battery, 400W more continuous output, 1,500 more rated cycles, 100W more solar ceiling and three more years of cover, and it is the one that finishes the 320Wh overnight CPAP profile with 115Wh in hand while the EB3A stops 92Wh short of it. A leftover EB3A stays the right answer in two situations and no others: you are carrying it far enough that six pounds registers, or you need the 12V car socket its record carries and the Power 500's does not. If you want a BLUETTI the maker still stocks in that size, the Elite 30 V2 is the unit that replaced the EB3A. Buy neither of these two for standby duty on a desktop, and neither for a real blackout list.

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 3.9/5 (33rd percentile of 25 Personal-class units), and Power 500 rates 4.6/5 (74th percentile of 20 Compact-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.
Noise: Ask About Duty Cycle, Not Decibels
Two makers, two methods, two best-case figures, so the 25dB against 50dB here is not a measured gap and should not be read as one. Both describe the quietest state each unit can be in, which means both are louder while charging or under real load. And a published decibel figure cannot tell you the part that actually wakes people: how often the fan runs, and whether it runs while the unit sits idle on the charger. If this one is sleeping in the bedroom with you, that is the question to ask.
Surge: A Ratio Is Not a Wattage
The EB3A genuinely wins this one on paper. A 2x peak over its 600W continuous rating is the headroom a compressor or a drill wants for the half-second it spikes, and the Power 500's record publishes no peak at all above its 1,000W continuous rating, which is a hole in the documentation rather than proof of a hard wall, so plan its motor-starting at face value. The line worth keeping: if your motor's rated draw sits comfortably under 600W, the EB3A has the published answer. Above 600W the ratio stops deciding anything and the continuous rating takes over.
UPS Mode: Two Ceilings, No Stopwatch
Both list a UPS mode, at different rated speeds. The Power 500 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The EB3A is rated ≤30ms — a transfer this long is one many desktops will NOT ride through, so plan on reboots for sensitive gear. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: 5 Years vs 2
The Power 500 is covered for 5 years against the EB3A's 2 years. The Power 500's figure is a maximum rather than a guarantee — it depends on buying from DJI's own store, which is where the full five years is advertised. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Power 500 is rated for 4,000 cycles vs 2,500. In real life: at daily use, that's 11 vs 6.8 years. At weekend use (twice a week), it's 38 vs 24 years. One caution reading years across different sizes: a cycle is 512Wh on the Power 500 and 268Wh on the EB3A, so count lifetime energy — roughly 2,048 kWh against 670 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.

Analyst note
The EB3A is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the Power 500 works out at $0.15/kWh over its rated life. If you already own the EB3A, the hardware comparison still holds: over its rated life the EB3A delivers about 670 kWh and the Power 500 about 2,048 kWh.
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 support desk is the coin-flip in this matchup. Some buyers get a fast, competent answer. Others get weeks of email with a timezone sitting between replies, and an offer of a discount on a new unit where a repair belongs. Buying direct from BLUETTI rather than through a reseller tends to end better, and on a two-year term that distinction is worth settling before checkout.
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
The catalogue behind this unit is the widest in the category, which cuts both ways: plenty of upgrade paths later, but also older models that can become unrepairable once spare parts stop existing.
DJI
Ecosystem
New entrant (2024) — five power station models to date: Power 500, Power 1000 (since superseded by the V2 but still sold), Power 1000 V2, Power 1000 Mini, Power 2000. Buying a "Power 1000" listing? Check which revision it actually ships.
Support
Leveraging DJI's established global support and repair center network from the drone business. Generally positive reputation inherited from drone operations, but limited power-station-specific track record.
Community
There is no power-station community here yet. Questions about this unit land in forums full of drone pilots, which is fine for build quality and useless for long-term battery experience.
App experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique strength
The fast-charge port for DJI's own batteries is the real differentiator and it is proprietary: worth actual money if you already own DJI gear, worth nothing if you do not.
Worth knowing
DJI arrived in power stations in 2024, so there is no queue of five-year-old units to point at. What sits behind it instead is a hardware company with an existing global repair network, which is a different kind of reassurance. And the five-year term is a maximum, advertised for units bought from DJI's own store rather than a marketplace.
Analyst note
Two opposite bets. BLUETTI brings the deeper catalogue, the better-rated app and years of field history in this category, along with the least predictable support in it. DJI brings almost no power-station history and the infrastructure of a company that has been repairing expensive gear for years. Neither is a guarantee, so the printed term, up to five years against two, is the part you can actually hold either of them to.
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.
Power 500
FIXED CAPACITYFixed at 512Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 300W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Growth only counts if you can still buy in, and the EB3A is no longer sold (BLUETTI points owners to the Elite 30 V2). That leaves the Power 500: it is sealed at 512Wh, so buy the size that covers you now. The EB3A's fixed 268Wh still matters if you already own one, but it isn't a reason to pick it over the Power 500.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI EB3A
The EB3A's field file is the loudest on this page, in both senses. Owners consistently report the fan cycling on and off at idle, one describing it running every 20 minutes even fully charged with the AC input inA3, another a periodic buzz every 10 to 15 minutes that sometimes precedes itA4, another a 25-second sequence of electrical noises when it kicks inA2, and one tracing the wobble to an unbalanced fanA1. A reviewer put the charging fan on a level with a cordless tool battery chargerA12.
The more serious pattern is the light-load UPS failure. Owners across 2022 to 2024 report false overload shutdowns at 40 to 60W in UPS mode, including one whose CPAP tripped it two to three hours into the night on a 40W drawA5A7, one who counted the same failure in every unit he knew of in that roleA8, and one for whom the firmware update made the fault more frequent before support ran out of ideasA6A9. A second owner never got a reply to an app support ticket at allA10, and one reported enough harmonics on the AC line to disturb a monitor standing next to itA11. Against that, extended testers are warmerA13A16A17: a 60-day run across two camping trips, an 18-hour outage and five days of van life ended in a would-buy-againA16, another reviewer called it well polished for how much it crams into the size while naming the clunky app and missing port coversA13A14, and one measured about six hours of CPAP on a charge with a wall refill in just over fourA17. Our own coverage note flags that this positive testimony is review-site testing rather than multi-year ownershipA0.
“Bluetti advertises the EB3A as "tiny but mighty," and I have to agree. They crammed a lot of ports and functionality into a very portable package... it seems to be a very well-polished product.”

DJI Power 500
The Power 500's field record is thin and worth saying so: four review-site entries, no long-term owner accounts, and a researcher note that the sourcing is established review sites rather than ownersB0. What exists is consistent. One reviewer measured it holding a 905W load and briefly riding a 1,500W spike past its 1,000W rating, and rated it more efficient than DJI's larger Power 1000B3. Another put the carry weight at about 7.3 kg, which is the 16.1 lbs our record carriesB2. The cycle and lifespan figures come from DJI by way of the review rather than from independent measurementB1, and one review flagged that the box ships with only a wall plug, no solar or car-charging cablesB4. Treat the absence of complaints as absence of data, not proof of reliability.
“A 512Wh LFP battery with up to 1,000W output; the automotive-grade LFP cells are rated up to 3,000-4,000 cycles for roughly a 10-year lifespan.”

Every owner claim in this report is traceable to a published source. The bracketed references above resolve here.
Recurring owner themes
- Multiple owners across forums (2022-2024) report the EB3A randomly shutting off or throwing false 'overload' errors under light loads (40-60W) when used in UPS mode for CPAPs, computers, or routers — a persistent, unresolved issue even after firmware updates. [EB3A · 6 entries]
- Recurring complaints about fan noise and odd fan behavior (ramping, buzzing, wobble) span from 2022 through 2024, spanning silent mode, idle, and charging states, suggesting an ongoing hardware/firmware characteristic rather than a one-time defect. [EB3A · 5 entries]
- Owners report poor or unresponsive Bluetti customer support when troubleshooting UPS failures, including unhelpful firmware fixes and unanswered app support tickets. [EB3A · 2 entries]
- Despite reliability complaints in UPS use, several long-term/extended testers (60+ days, CPAP overnight use) report satisfaction with portability, build quality, and real-world runtime for camping/outage scenarios. [EB3A · 3 entries]
- Light, efficient LFP unit with strong real-world output and drone-pilot appeal; the caveat is minimal included accessories. [Power 500 · 3 entries]

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
Who Should Buy Which
Buy the EB3A if you…
- →You are walking with it. A kayak, a bike trailer, a long haul from the car park: six pounds is worth more than watt-hours when you are the one carrying them.
- →Your load list is 12V. A small car fridge, a tyre inflator, a 12V fan. The EB3A's record carries the socket and the Power 500's does not.
- →You want a first, small station for phones, lights and a laptop on an afternoon out, you have found leftover stock, and you are clear-eyed that it is an afternoon unit. At 44% used on that profile, it does that job and finishes it.
Buy the Power 500 if you…
- →Anything overnight, and anything medical. It is the only one of the two that finishes the 320Wh CPAP profile, and it does it with 115Wh left.
- →Anything rated between 600W and 1,000W. A microwave, a kettle, a corded tool: one of these units has that inside its continuous rating and the other does not.
- →You already own DJI gear. The fast-charge port is proprietary, so it is worth real money if you already fly DJI gear and nothing at all if you do not.
- →You will use it weekly for years. Three times the lifetime energy and up to five years of cover is the whole answer to that question.
If neither fits
If your list is a fridge through an eight-hour outage, a full workday off-grid or van life, close the tab: that profile wants 1,645Wh and the bigger of these two still comes up 1,210Wh short, so buying either means buying twice. You want a 1,000Wh-and-up unit. The same applies if you need genuine UPS for a desktop with unsaved work, because the EB3A's standby behaviour is disputed in its own field fileA5A15 and the Power 500's rated 20ms class has no measurement behind it in oursB0.
The Bottom Line
Take the Power 500. Three times the lifetime energy, nearly twice the working capacity, 400W more continuous output and up to five years of cover, and it is the only one of the two that gets a CPAP through the night. BLUETTI no longer sells the EB3A, so this page shows it no price, and the capability argument decides it on its own.
The EB3A keeps one honest job: the light one you carry, with a 12V socket the Power 500 does not have. If that is the unit you need, you knew it two paragraphs ago, and BLUETTI's Elite 30 V2 is the live unit in that size. For everyone else, six extra pounds is the price of a battery still working long after the other one has finished its rated life.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 500 worth buying over the BLUETTI EB3A?
For almost everyone, yes, and BLUETTI no longer sells the EB3A, so this page shows it no price. The Power 500 brings 244Wh more battery, 400W more continuous output, 1,500 more rated cycles, 100W more solar ceiling and three more years of cover, and it turns a unit that cannot finish an overnight CPAP profile into one that finishes it with 115Wh spare. The buyers who should take a leftover EB3A anyway are the ones carrying it any real distance, and the ones who need its 12V car socket.
Can the BLUETTI EB3A run a CPAP all night?
Not on the overnight profile used here. 268Wh derates to 228Wh of working energy, and at the 40W that profile assumes, that is about five and a half hours, leaving it 92Wh short of the 320Wh a full night needs. One tester measured about six hours on a charge. There is a second reason to skip it for this job: owners report false overload shutdowns in UPS mode at exactly 40 to 60W, unfixed by firmware between 2022 and 2024.
Which is quieter, the EB3A or the DJI Power 500?
On paper the Power 500, at 25dB published against the EB3A's 50dB, but both are maker best-case figures measured each to its own method, so that is not a like-for-like gap. The more useful answer is behavioural: owners report the EB3A's fan cycling on and off at idle, even fully charged with the wall plug in, and a buzz that precedes it. If the unit sleeps in your bedroom, weigh that rather than the decibel figures.
Does the DJI Power 500 charge from solar panels?
Up to 300W, but not straight out of the box. DJI's record carries no built-in solar charge controller, so the solar input runs through a separate proprietary adapter, and one review noted the unit ships with only a wall plug, with no solar or car-charging cables included. The EB3A takes up to 200W and needs only a panel. If solar is your main charging plan, price that adapter before you compare the two.
Will either of these run a refrigerator during a power outage?
For a few hours, not for a day. The EB3A's 1,200W peak over a 600W continuous rating gives it the 2x headroom a compressor startup wants, while the Power 500's record publishes no peak above its 1,000W continuous rating at all. On energy, though, the eight-hour blackout profile needs 1,645Wh, and the Power 500 is 1,210Wh short of it while the EB3A is 1,417Wh short. Use either as a stopgap; do not plan an outage around them.
