Spec deltas
Both carry the BLUETTI name, but they're built for different buyers. The EP500Pro (5,120Wh, 3,000W) and the Pioneer 150 AC240 (1,536Wh, 2,400W) come from different product lines with different engineering priorities and a $2,500 price gap. The EP500Pro has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the EP500Pro's 3,000W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Pioneer 150 AC240's 2,400W inverter still runs most single appliances; the EP500Pro's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the EP500Pro keeps a fridge alive for roughly 29 hours vs the Pioneer 150 AC240's 9 hours. The cost? Portability. At 187 lbs, the EP500Pro is a two-person lift you set down once and leave. The Pioneer 150 AC240 at 72 lbs is more manageable, though still not light.
Pick the EP500Pro if your primary use is 8-hour blackout or remote workday. Go with the Pioneer 150 AC240 if you primarily need it for tailgate party. 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 EP500Pro
With a massive 3,000W output (and 6,000W surge), the EP500Pro can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 187 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
Trade-offs
- –Significantly heavier (+115 lbs), making it harder to move.
- –Very heavy unit that may be difficult for one person to lift.
BLUETTI Pioneer 150 AC240
With a massive 2,400W output, the Pioneer 150 AC240 can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 72 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Lighter by 115 lb
- +Longer warranty
Trade-offs
- –Weaker inverter (-600W) limits appliance compatibility.

We ran the math on six 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 gives you a powered weekend: the EP500Pro has the energy but doesn't travel, and the Pioneer 150 AC240 covers about 62% of the 2,100Wh. One can't go; the other can't finish.

EP500Pro
The Pioneer 150 AC240 doesn't finish — 1,306Wh usable against the 1,645Wh this needs leaves it 339Wh short, about 79% of the scenario covered. The EP500Pro covers it with 2,707Wh to spare.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both of these cover the night several times over — capacity isn't the question here. What would separate them is fan noise, but EP500Pro doesn't publish a figure, so there's nothing to hold it to. Neither is sold new any more, so weight and fan noise is what's left to weigh, alongside whatever you can find used.

EP500Pro
The EP500Pro clears the workday at 21% used, banking 3,442Wh — late work, extra calls, or a second laptop charge without arithmetic. The Pioneer 150 AC240 at 70% also finishes, with 396Wh of slack for the unplanned.

Tailgate Party
Game day power for the crew
Pioneer 150 AC240
The EP500Pro at 187 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the Pioneer 150 AC240 by default — and it earns it, covering the 670Wh with 636Wh to spare. Capacity was never the EP500Pro's problem here; getting to a tailgate was.

Neither unit
Neither unit covers this scenario's 4,685Wh: the EP500Pro comes up 333Wh short (about 93% covered) (its nameplate 5,120Wh actually clears this — the flat 15% conversion allowance is what tips it under), the Pioneer 150 AC240 3,379Wh (28%). Treat this as partial cover — enough for the essentials in it, not the whole 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, EP500Pro rates 3.5/5 (11th percentile of 20 Home Backup-class units), and Pioneer 150 AC240 rates 4.0/5 (42nd percentile of 27 Everyday-class units).

Weight Reality Check
Neither unit is grab-and-go. The Pioneer 150 AC240 (72 lbs) is manageable solo but heavier than a large checked suitcase. The EP500Pro (187 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 115 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Pioneer 150 AC240: 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.
EP500Pro: Fixed Capacity
The EP500Pro is sealed at 5,120Wh, and that is the ceiling. Normally the counterpoint would be that the Pioneer 150 AC240 can add expansion batteries, but that isn't a live option here: the Pioneer 150 AC240 is no longer sold, and BLUETTI points owners to the AC200L. For a new purchase the expansion question doesn't arise between these two, so the EP500Pro's fixed 5,120Wh is simply what you get.
Pioneer 150 AC240: Power Lifting to 3,600W
The Pioneer 150 AC240 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 3,600W from its 2,400W 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 1,536Wh 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 EP500Pro carries no Power Lifting figure, only a 6,000W surge peak, which is a different rating, so check BLUETTI's own spec sheet before reading this as something the EP500Pro lacks.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Pioneer 150 AC240 is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The EP500Pro 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: 6 Years vs 5
The Pioneer 150 AC240 is covered for 6 years against the EP500Pro's 5 years. The EP500Pro'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.
EP500Pro: Noise Level Not Disclosed
The Pioneer 150 AC240 publishes its noise level (50dB); the EP500Pro doesn't publish one. That isn't evidence the EP500Pro 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 Pioneer 150 AC240'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 EP500Pro before deciding.

Analyst note
Neither is sold new any more, so there is no price left to work a cost per kWh from, and what either costs you now depends on the used market. The hardware comparison still holds: over its rated life the EP500Pro delivers about 17,920 kWh and the Pioneer 150 AC240 about 5,376 kWh. One thing to know reading the table: both carry the same 3,500-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.
Growth path
EP500Pro
FIXED CAPACITYFixed at 5,120Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 2,400W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Pioneer 150 AC240
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,536Wh.
Accepts up to 1,200W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Expansion batteries are BLUETTI-specific. You're investing in the BLUETTI ecosystem.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither of these is sold new any more, so there is no growth path to buy into on either side. If you already own one: the EP500Pro is fixed at 5,120Wh and the Pioneer 150 AC240 takes expansion batteries. As a purchase decision, expandability isn't the question here.
The Bottom Line
The full picture comes down to this. The EP500Pro 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 Pioneer 150 AC240 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the EP500Pro nor the Pioneer 150 AC240 feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. Prices on portable power stations fluctuate frequently. Both BLUETTI 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.
How does the 3,584Wh capacity difference actually affect daily use?
The EP500Pro's 5,120Wh battery keeps a mini-fridge running for roughly 29 hours vs the Pioneer 150 AC240's 9 hours. Where it really matters: during an 8-hour blackout running your fridge, router, lights, AND charging your phone simultaneously (about 1,645Wh total), the EP500Pro handles it while the Pioneer 150 AC240 runs dry. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The EP500Pro's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the EP500Pro, or is the Pioneer 150 AC240 the only portable option?
Neither is "portable" in any hiking sense. The Pioneer 150 AC240 (72 lbs) and the EP500Pro (187 lbs) are both appliances you place and leave. The 115-lb difference matters when loading into a vehicle or moving between rooms, but that's about it. If true portability is your priority, look at units under 20 lbs in a different class entirely.
How fast can each unit recharge from solar panels in real conditions?
On paper, the EP500Pro accepts 2,400W vs the Pioneer 150 AC240's 1,200W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 3.0 hours for the EP500Pro and 1.8 hours for the Pioneer 150 AC240. That gap widens on cloudy days, when the EP500Pro's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the EP500Pro's advantage is substantial.
Does the Pioneer 150 AC240's expandability make it the safer long-term buy?
Not necessarily. The Pioneer 150 AC240 can add BLUETTI batteries, but it starts at 1,536Wh — below the EP500Pro's sealed 5,120Wh. A first expansion battery mostly buys back capacity the EP500Pro already gives you out of the box; expandability only pulls ahead if you expect to grow past 5,120Wh. If you don't, the EP500Pro's larger fixed capacity is the simpler, complete package — not a dead end, just already the bigger battery.
Bottom line: should I buy the EP500Pro or the Pioneer 150 AC240?
Neither, if you're buying new: both are no longer sold. The comparison on this page still helps if you own one.
