Head-to-head test
BLUETTI Apex 300 vs BLUETTI EP500
The EP500 sells one thing the Apex 300 can't match, a second night of stored power, and the price is $1,300 more, another 83 pounds, and an inverter a little over half the size.

Spec deltas
The cheaper of these two is also the stronger one nearly everywhere it counts. The Apex 300 lists at $1,699 and the EP500 at $2,999, and that extra $1,300 buys 2,355Wh more battery, 5,120Wh against 2,765Wh. What it gives back is an inverter rated for 2,000W instead of 3,840W, a pack rated for 3,500 cycles instead of 6,000, and another 83 pounds to find a home for.
The EP500's depth is real, and it wins the night that matters most to a home buyer: the outage that doesn't end at bedtime. Come morning it has most of another evening banked while the Apex 300 has under half of one. That is the entire argument for spending more here, and for one specific buyer it is enough.
For everyone else, take the Apex 300. It costs less, it hands over nearly the same energy across its rated life, it starts harder loads, it takes the 240V and RV plugs the EP500 has none of, and one adult can get it into a truck bed. The EP500 is the right box for a basement corner in a house with long outages, and the wrong one almost everywhere else.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Price is the part that is not close. $2,999 against $1,699 is 77% more money for that 8% of extra energy, which lands at about $0.17 per lifetime kilowatt-hour on the EP500 against $0.10 on the Apex 300. Every kilowatt-hour the EP500 will ever deliver costs roughly 70% more than the same one from the Apex, and capacity is the only line item it has to argue back with.
Apex 300: 6,000 rated cycles at 2,765Wh a cycle, or 16,589 kWh of rated lifetime energyEP500: 3,500 rated cycles at 5,120Wh a cycle, or 17,920 kWh of rated lifetime energyApex 300 at $1,699 against EP500 at $2,999
Why it mattersIf you plan to own this for years rather than for one storm, the Apex 300 is the unit that keeps being cheaper long after the receipt is filed.
continuous output
That caps what the depth is for. Nothing drawing over 2,000W is on the EP500's menu at any state of charge, and the two plugs that carry loads like that, a 240V outlet and a 30A RV socket, sit on the Apex and read as zero on the EP500. A well pump or a dryer circuit doesn't care that there is 5,120Wh behind an outlet it can't use.
Apex 300: 3,840W continuous, 7,680W surge, with one 240V outlet and one 30A RV outletEP500: 2,000W continuous, 4,800W surge, with zero 240V outlets and zero 30A RV outlets on its recordEP500 capacity 5,120Wh against the Apex 300's 2,765Wh
Why it mattersIf your backup list includes a 240V appliance, or your rig ends in a 30A cord, the EP500 isn't the more expensive option here, it's the wrong one.
solar input
The Apex's answer to the shorter night is sunlight, and that is where its case softens. Its 2,400W solar figure is the biggest input number on this page and the most contested: nothing in our field coverage demonstrates the unit charging anywhere near it, and what coverage exists is early reviewer testing rather than measured charge runsA0. Treat it as a published rating. The EP500's smaller input has at least been timed by someoneB7, and stored energy never has to wait for the weather.

Why it mattersIf your outages have a history of running into a second or third day, especially under grey skies, the EP500's depth is the one thing here worth paying extra for.
Buying that socket back means the Hub D1 at around $300A7A11, bolted on rather than built in. The Apex is still the cheaper unit by a wide margin afterwards, but it is a real line item, and the accessory ladder keeps climbing: one reviewer puts the parallel box for linking two Apex units at about $699A12.
Apex 300 port record: six AC outlets, two USB-A, two USB-C at 100W, and zero 12V car outletsEP500 port record: four AC outlets, two USB-A, two USB-C at 100W, and one 12V car outletReviewers price the Hub D1 accessory that adds DC output at about $300A7A11
Why it mattersIf your load list is full of 12V gear, either budget the hub into the Apex's price or take the EP500, which has the socket on board.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The EP500 holds 5,120Wh to the Apex 300's 2,765Wh, and that gap is the only reason on this page to pay more.
continuous output
Every scenario the EP500 wins, it wins by having energy left over rather than by doing something the Apex 300 cannot do. That distinction is the whole purchase, because a reserve is only worth money if you ever reach it.
Look at where the headroom actually gets spent. A CPAP asks for 320Wh a night and a remote workday 910Wh, and both units treat those as rounding errors. The EP500's depth only becomes decisive at the far end, the outage that runs into a second day or the stretch of grey ones. If you can name the last time you needed more than one night off-grid, buy the depth. If you can't, you are paying for a floor you will never walk on.
Lifetime Value
Selected because: Both packs hand over within 8% of the same energy across their rated lives, 16,589 kWh against 17,920 kWh, at prices that are nowhere near as close.
cost / lifetime kWh
The per-kilowatt-hour gap only bills you if you actually cycle the battery. A unit that comes out of the closet twice a year for storms will age out long before either pack approaches its rated cycle count, and for that buyer the lifetime arithmetic is a footnote to the sticker price. The sticker price points the same way, which makes this the easy version of the decision.
The EP500 does claw something back here. Its cycles are bigger, 5,120Wh moved per cycle against 2,765Wh, so a real night of use eats a smaller fraction of its rated life. Run both hard every day and it still runs out of years first, 9.6 against 16.4. Run them a few times a season and neither will ever notice the difference. This is a heavy-use gap, so work out how hard you will actually run it before you let it decide anything.
Portability & Form Factor
Selected because: 83.8 lbs against 167 lbs settles two of the six scenarios before capacity gets a vote.
weight
167 pounds is not a unit you carry, it's a unit you install: two people, a spot chosen in advance, and no plans to revisit the decision. That is the right shape for a basement backup and a disqualification for anything involving a tailgate. Reviewers who moved the Apex 300 call it manageable thanks to the handles but genuinely hard to carry any distance, one of them unable to lift it onto a tableA6A8.
So the honest framing isn't heavy against light. It's heavy-and-portable against heavy-and-permanent, and permanent only works if your power problem stays inside one building.
Growth Path
Selected because: One of these takes expansion batteries and the other is sealed at 5,120Wh, which sounds like it settles the matchup and doesn't.
solar input
Expansion looks like the Apex 300's trump card and mostly functions as a catch-up mechanism. It starts at 2,765Wh against a fixed 5,120Wh, so the first battery you bolt on is largely buying back capacity the sealed unit already includes. Past 5,120Wh the Apex is the only one of the two that can go there at all, and that, not the brochure line, is what the expansion port is worth.
The other growth path is sunlight, and it needs an asterisk. The Apex 300's 2,400W published solar input is the largest input figure on this page and the most contested one: nothing in our field coverage shows it charging anywhere near that rate, and the coverage that exists is early reviewer testing rather than measured charge runsA0. The EP500's 1,200W is the smaller number, but a reviewer actually timed a full refill at as little as 4.7 hoursB7. Don't buy the Apex on the strength of its solar ceiling. Buy it for the inverter and the expansion port, and treat that figure as a bonus nobody has proven yet.
Your Life, Your Pick
Selected because: The six profiles split three ways: two to the Apex 300 on portability, two to the EP500 on leftover capacity, one a dead heat, and one that neither unit covers.
Read the split as a question about where the unit lives rather than what it can do. Both of the Apex 300's wins are wins by default, because 167 pounds doesn't come to a campsite or a parking lot. Both of the EP500's are wins on leftovers, because the Apex finishes those days too, just with less in the tank.
Only the van-life row separates them on something neither can fake, and there it separates them into the same answer: not enough. Nothing in this table rules the Apex out. It only names the one night it would rather not be asked to work.

Weekend Camping
Two nights off-grid with essential comfort
Apex 300
The Apex 300 covers this 2,100Wh weekend with 250Wh left, which is a pass rather than a cushion: it finishes at 89% used. It wins anyway, because 167 pounds doesn't get to a campsite. If your weekends run heavier than this profile, plan on a solar top-up instead of assuming headroom.

EP500
Both units get through the night. The EP500 gets through the next one too, and that is the whole case for it. Check your own history: if your outages end by breakfast, the Apex 300's leftover is enough and the extra capacity is a reserve you won't reach. If they run into a second day, the EP500 is the only one of the two that gets there without sun.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP asks for roughly 320Wh a night, 14% of the Apex 300 and 7% of the EP500, so capacity decides nothing. Fan noise would, and only one of these has a published figure to be held to: 45dB on the Apex, nothing at all on the EP500. Decide on weight, price, and whether you can live eighteen inches from a fan with no published figure behind it.

EP500
Calling this one for the EP500 is a technicality. It finishes at 21% used against the Apex 300's 39%, and both have hours of slack for a late call or a second laptop charge. A laptop, a monitor and a router will never find the bottom of either battery, so if this is the load you're buying for, you're only choosing which unit to under-use.

Tailgate Party
Game day power for the crew
Apex 300
A tailgate is an outlet problem more than a capacity one. The Apex 300 clears the 670Wh with room to spare, brings six AC sockets to the EP500's four, and has enough surge ceiling that the 400W peak here never registers. It also weighs roughly half what the EP500 does, which is the part that decides whether it comes at all.

Neither unit covers a 4,685Wh day. The EP500 gets to 93% of it, coming up 333Wh short once the flat 15% conversion allowance is taken off its 5,120Wh nameplate, and the Apex 300 covers about half. Full-timers at this draw should be shopping hardwired house banks, not portable boxes. If your van is a weekend van rather than a home, either unit works with a daily solar top-up.

Conclusion
September 13, 2026
Verdict: the Apex 300
Buy the Apex 300. It costs less up front, delivers nearly the same total energy across its rated life (16,589 kWh against the EP500's 17,920 kWh) at a much lower cost per kilowatt-hour, runs a 3,840W inverter against 2,000W, holds the higher surge ceiling, carries a 240V outlet and a 30A RV outlet the EP500 records as zero, and weighs 83 pounds less. The EP500's single real advantage is 5,120Wh of stored depth, and it is decisive in exactly one situation: a multi-day outage in a house where the unit never has to move. If that is your situation, the extra money is well spent. If it is not, the Apex is the better unit on every axis you will actually touch, with two things to budget for: there is no 12V car socket without an accessory that reviewers price around $300A7A11, and early firmware has been the source of most owner complaints so farA1A2A3A4.
Today the Apex 300 is $1,499, $200 under its typical $1,699. The verdict weighs typical prices, not today's. Prices checked 16 days ago.

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 4.9/5 (92nd percentile of 26 Large-class units), and EP500 rates 3.4/5 (5th percentile of 20 Home Backup-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.
Two Lifts, Two Different Problems
83.8 lbs is a bent-knees, two-hands lift that one adult can get into a truck bed and should not attempt on basement stairs. 167 lbs isn't a lift at all, it's an installation: a second person, a spot chosen in advance, and no plans to move it again. The 83 lb difference gets paid once on the EP500, when you put it where it will live. On the Apex it gets paid every trip, which is only a cost if you take trips.
Read the 45dB the Way It Was Published
45dB is about a running refrigerator, close enough to matter in a bedroom. It is also a spec-sheet figure rather than something measured here, and published noise numbers tend to describe the quiet end of a unit's range instead of what it does under a heavy charge. Treat it as the floor of the Apex 300's behavior rather than its ceiling.
The Expansion Path Starts From Behind
The Apex 300 takes expansion batteries and the EP500 is sealed, which reads like a win until you check the starting line. The Apex opens at 2,765Wh against a fixed 5,120Wh, so the first battery you add is mostly buying back capacity the EP500 includes in the box. Expansion only becomes an advantage if your needs climb past 5,120Wh. That is the Apex's honest weakness on this page: its growth story costs money to reach a place its rival ships from.
Apex 300: Power Lifting to 7,680W
The Apex 300 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 7,680W from its 3,840W inverter. It does that by delivering less power than the appliance asks for, not more than the inverter has: the heater still works, it just heats more slowly. Two things follow. BLUETTI scopes the mode to purely resistive loads — a heater, a kettle, an incandescent lamp — so it does nothing for a fridge compressor, a pump or a power tool, and this record publishes no surge figure at all, so read the mode as a resistive-load feature rather than as starting ability. And it is not a reason to size down, because running a load that big from 2,765Wh is a short session either way. Genuinely useful if a heater or a kettle is why you're buying; beside the point otherwise. Our record for the EP500 carries no Power Lifting figure, only a 4,800W surge peak, which is a different rating, so check BLUETTI's own spec sheet before reading this as something the EP500 lacks.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Apex 300 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The EP500 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. 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: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Both figures are maximums rather than guarantees — they depend on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. Worth saying because the per-dollar framing can suggest otherwise: the Apex 300 works out at 2.9 years of cover per $1,000 spent against the EP500's 1.7, but that spread is the price gap, not the terms.
Count Energy, Not Years
6,000 rated cycles against 3,500 looks like the Apex 300 outliving the EP500 by a mile, and at daily use it does: 16.4 years against 9.6. But a cycle isn't the same thing on both units. The Apex moves 2,765Wh per cycle and the EP500 moves 5,120Wh, so the lifetime energy totals nearly converge. Neither figure is a death date either. At the cycle limit these packs are down to roughly 80% of original capacity, which is still a working battery.
EP500: Noise Level Not Disclosed
The Apex 300 publishes its noise level (45dB); the EP500 doesn't publish one. That isn't evidence the EP500 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 EP500 before deciding.
Full record above — the Test Desk pick is the Apex 300.

Analyst note
The Apex 300 wins on both sticker price and long-term value. At $0.10/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner. One caution on the lifespan row: the Apex 300 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the EP500 still delivers more over its shorter horizon (17,920 vs 16,589 kWh). Years measure wear, not usefulness.

Analyst note
Don't read the Apex 300's expandability as a straight win here: it starts at 2,765Wh, below the EP500's 5,120Wh, so a first expansion battery largely buys back capacity the EP500 already includes. It only pulls ahead if you'd grow past 5,120Wh — short of that, the EP500's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI Apex 300
Field data on the Apex 300 is thin and earlyA0: most of what exists is press review units plus a handful of posts on BLUETTI's own forum, with no long-term owner reports yet. What is there points one direction, because owners report firmware updates breaking things shortly after they install themA1A2A3A4. One unit stuck in Backup mode with the app refusing to switch it outA1, another throwing Error 004 and stopping its charge at 97%A2, Bluetooth and Home Assistant disconnects that began after an updateA3, and an app that keeps offering an update it has already appliedA4. None of that is a hardware verdict, and firmware is the one category a later release can fix, but it is the pattern in the record as it stands.
On the physical side, reviewers who hauled it call the weight workable because of the handles and still hard to move any distance, with one saying he could hardly carry it more than a few feet and couldn't get it onto a tableA6A8. The fans drew praise rather than complaints, described as relatively tame under load next to units that sound like small jet enginesA5. The recurring gripe about missing DC output is worth separating from the noise around it: those entries are right that the Hub D1 costs about $300A7A11 and that the parallel box runs near $699A12, while the base unit's own record lists USB-A and USB-C on board. The app itself was called sluggish next to EcoFlow's and Anker'sA10, and the rubber bungs over the sockets get annoying with oversized plugsA9.
“I was using Bluetti-bt until the latest Bluetti firmware update. I then started having disconnects.”
BLUETTI EP500
The EP500's record is reviewer test units rather than ownersB0: no long-running owner thread specific to the non-Pro EP500 turned up, and most BLUETTI forum activity found centers on the EP500 Pro or the AC series instead. Weight is the one point every reviewer agrees on, called the unit's biggest problem and simply too heavy to take campingB1B9.
What reviewers liked lines up with what the specs implyB3B4B5B6. The UPS mode was singled out as a genuine safeguard for medical equipment during an outageB3, app control saves a trip to the garage to check on itB4, the pack stays cool enough that a phone charging beside it isn't at riskB5, and the capacity holds a fridge for days at a stretchB6. Two caveats from the same pages: the touchscreen was called laggyB2, and the 1,200W solar input was timed at a full refill in as little as 4.7 hoursB7, slower than the Apex's rating but a number somebody actually put a clock on.
“The EP500's UPS mode is a true lifesaver for medical equipment users when the power goes out.”

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 Apex 300 if you…
- →You want one box that goes camping in October and backs the house in January. At 83.8 lbs it is a one-adult load into a truck bed, and it is the only one of the two with a 240V outlet and a 30A RV socket on it.
- →Your backup list includes something that starts hard: a well pump, a compressor, a shop tool. 3,840W continuous with 7,680W of surge is the bigger tap, and the EP500's 2,000W is the ceiling you would be hitting.
- →You will genuinely cycle it, with weekly camping, seasonal RV use, or daily solar shuffling. That is where 6,000 rated cycles stops being a spec and turns into years.
- →You want the option to grow later and you are clear-eyed about what it costs: the first expansion battery mostly gets you to where the EP500 already starts, and only past 5,120Wh does the port become an advantage.
Buy the EP500 if you…
- →Your outages have a history of running into the next day, and the unit is going to sit in one corner of a basement or garage for the rest of its life. That is the case where 5,120Wh in a sealed box earns the money.
- →Everything on your backup list runs under 2,000W: fridge, router, lights, a CPAP, a couple of laptops. You will never meet the inverter ceiling, so depth is the only spec left standing.
- →You want a 12V car socket on the unit itself for a DC fridge or a tire pump, without buying an accessory to get one.
If neither fits
Full-time van dwellers drawing about 4,685Wh a day should skip both. The EP500 reaches 93% of that day and the Apex 300 about half of it, so either one has you rationing before dinner. A hardwired house bank with its own inverter is the right shape for that load. And if what you actually want is something you can pick up with one hand and carry across a campsite, neither of these is that unit either. Go look at the small carry-handle class and leave both of these to the people who need a fixed installation or a truck.
The Bottom Line
Take the Apex 300. The two packs hand over nearly the same total energy across their rated lives, and only one of them charges you a second time for the deeper tank. It also runs the bigger inverter, starts the harder loads, takes the 240V and RV plugs the EP500 records as zero, and can be moved by one person who doesn't own a hand truck.
The EP500 earns its keep for one buyer, and it is worth naming plainly: the person whose outages run two days and whose unit is never leaving the basement. Depth is the one advantage on this sheet you cannot work around on the Apex unless the sun cooperates or you buy another battery. Everyone else should take the lighter, stronger, longer-lived box and put the difference toward panels.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI EP500 worth the extra money over the Apex 300?
Only if your outages run past one night and the unit will never move. The EP500's advantage is stored depth, 5,120Wh against 2,765Wh, which is the difference between starting day two with reserves and starting it with a fraction of an evening. Output, surge, weight, rated cycles, and cost per kilowatt-hour over the pack's life all belong to the Apex 300.
Can the Apex 300 run 240V appliances or an RV hookup?
It is the only one of the two set up for either. The Apex 300's record lists one 240V outlet and one 30A RV outlet, and the EP500 lists zero of both. The Apex also carries the higher surge ceiling at 7,680W against 4,800W, though whether your particular pump or compressor starts depends on its own inrush rather than on a headline number.
Does the BLUETTI Apex 300 have a 12V car outlet?
No. Its port record lists six AC outlets, two USB-A and two USB-C at 100W, and zero 12V car outlets, so there is no cigarette-lighter socket on the unit itself. Getting DC output means the Hub D1 accessory, which reviewers price at about $300. The EP500 has one 12V socket on board.
Which one is quieter, the Apex 300 or the EP500?
There is no honest answer, and be suspicious of anyone who gives you one. The Apex 300 publishes 45dB, roughly a running refrigerator, and BLUETTI publishes no figure at all for the EP500. Published noise numbers usually describe the quiet end of a unit's range rather than the loud one, so treat the Apex's as a floor and the EP500's silence as missing data rather than bad news.
Can I add more batteries to the Apex 300 later?
Yes, it accepts BLUETTI expansion batteries, while the EP500 is sealed at 5,120Wh. Price the path honestly, though: the Apex starts at 2,765Wh, so the first expansion battery largely buys you back to where the EP500 begins. The port only becomes an advantage if you end up needing more than 5,120Wh.
