Spec deltas
Both carry the BLUETTI name, but they're built for different buyers. The Apex 300 + 2×B500K (13,005Wh, 3,840W) and the Elite 320 (3,200Wh, 1,800W) come from different product lines with different engineering priorities and a $4,299 price gap. The Apex 300 + 2×B500K 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 Apex 300 + 2×B500K's 3,840W inverter has the headroom for a window AC, a full-size fridge, and power tools. The Elite 320's 1,800W inverter still runs most single appliances; the Apex 300 + 2×B500K's real edge is surge headroom for the biggest motor starts and stacking several heavy loads at once. On stamina, the Apex 300 + 2×B500K keeps a fridge alive for roughly 74 hours vs the Elite 320's 18 hours. The cost? Portability. At 282.2 lbs, the Apex 300 + 2×B500K is spread across boxes you site once and leave. The Elite 320 at 75 lbs is more manageable, though still not light.
Pick the Apex 300 + 2×B500K if your primary use is 8-hour blackout or remote workday. Go with the Elite 320 if you primarily need it for weekend camping or tailgate party. Most buyers stop at the sticker price and miss this: over a full lifespan the Apex 300 + 2×B500K works out to about $0.07/kWh against the Elite 320's $0.11, a gap that compounds in the Apex 300 + 2×B500K'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 Apex 300 + 2×B500K
With a massive 3,840W output, the Apex 300 + 2×B500K can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 282.2 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion. A standout feature is the value proposition: at roughly $0.42 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$4,299) than the Elite 320.
- –Significantly heavier (+207.2 lbs), making it harder to move.
- –Very heavy unit that may be difficult for one person to lift.
BLUETTI Elite 320
The 1,800W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. Weighing in at 75 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion. A standout feature is the value proposition: at roughly $0.34 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Costs $4,299 less
- +Lighter by 207.2 lb
Trade-offs
- –Weaker inverter (-2,040W) limits appliance compatibility.
- –Sealed capacity — the Apex 300 + 2×B500K can add batteries to grow past 3,200Wh; this one can't.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the Apex 300 + 2×B500K's 6,000, so it wears out sooner.

Weekend Camping
Two nights off-grid with essential comfort
Elite 320
The Apex 300 + 2×B500K at 282.2 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the Elite 320 by default — and it earns it, covering the 2,100Wh with 620Wh to spare. Capacity was never the Apex 300 + 2×B500K's problem here; getting to a campsite was.

Keep the essentials running through a night without power
Apex 300 + 2×B500K
Both survive the night. The Apex 300 + 2×B500K finishes at 15% used with 9,409Wh left — 5.7 more nights like it. The Elite 320 finishes at 60% with 1,075Wh, 65% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

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 Elite 320 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

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, Apex 300 + 2×B500K rates 3.5/5 (14th percentile of 29 Whole-Home / Off-Grid-class units), and Elite 320 rates 4.1/5 (46th percentile of 27 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The Elite 320 (75 lbs) is manageable solo but heavier than a large checked suitcase. The Apex 300 + 2×B500K (282.2 lbs) is spread across its boxes — no single lift, but nothing you reposition on a whim. That's a 207 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
Apex 300 + 2×B500K: 45dB Published
45dB is about as loud as a running refrigerator. 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.
Elite 320: Fixed Capacity
The Elite 320 is sealed at 3,200Wh — fine if that covers you, but it's the ceiling. By contrast the Apex 300 + 2×B500K can add expansion batteries, though the first thing it has over the Elite 320 is its own 13,005Wh base — expansion is the step after that, for the buyer who would outgrow 13,005Wh as well.
Power Lifting: 7,680W and 2,700W
Both units have BLUETTI's Power Lifting mode: the Apex 300 + 2×B500K to 7,680W on a 3,840W inverter, the Elite 320 to 2,700W on 1,800W. It works by delivering less power than the appliance asks for rather than more than the inverter has, so the appliance runs slower rather than not at all. 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. Surge is a separate figure: the Elite 320 publishes a 3,600W surge peak, the figure a motor's switch-on draw meets, and the Apex 300 + 2×B500K's record carries none. Neither Lifting figure speaks to motor loads. Judge the Lifting figures on which ceiling covers the resistive load you actually own.
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 Elite 320 works out at 4.5 years of cover per $1,000 spent against the Apex 300 + 2×B500K's 0.9, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Apex 300 + 2×B500K is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. One caution reading years across different sizes: a cycle is 13,005Wh on the Apex 300 + 2×B500K and 3,200Wh on the Elite 320, so count lifetime energy — roughly 78,029 kWh against 9,600 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.
Elite 320: Noise Level Not Disclosed
The Apex 300 + 2×B500K publishes its noise level (45dB); the Elite 320 doesn't publish one. That isn't evidence the Elite 320 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 + 2×B500K'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 Elite 320 before deciding.

Analyst note
The Elite 320 is sealed at 3,200Wh, which is fine if that covers you. The Apex 300 + 2×B500K starts at 13,005Wh and can grow beyond it with BLUETTI expansion batteries — real headroom the Elite 320 doesn't have if your needs climb toward partial-home backup.
The Bottom Line
The full picture comes down to this. The Apex 300 + 2×B500K 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 Elite 320 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the Apex 300 + 2×B500K nor the Elite 320 feels like the right fit, your power needs probably sit outside what these two target. For lighter use — weekend camping or phone/laptop charging — you'd be overpaying for capacity you'll rarely tap. Consider a unit in the 500–1,500Wh range instead. 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.
Is the Apex 300 + 2×B500K worth $4,299 more than the Elite 320?
The short answer: yes, if you'll actually use the extra capability. The Apex 300 + 2×B500K costs $4,299 more, but that premium buys you 9,804.8Wh more battery capacity (that's 56 extra hours of running a mini-fridge); 2,040W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 6,000 cycles — that's 16 years at daily use; 1,400W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.42/Wh vs $0.34/Wh. Factor in cycle life and the math flips: the Apex 300 + 2×B500K costs $0.07/kWh over its lifetime vs $0.11/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
How does the 9,804.8Wh capacity difference actually affect daily use?
The Apex 300 + 2×B500K's 13,004.8Wh battery keeps a mini-fridge running for roughly 74 hours vs the Elite 320's 18 hours. Both can handle a full 8-hour blackout setup (fridge + router + lights + phone charging ≈ 1,645Wh), but the Apex 300 + 2×B500K finishes with significantly more margin. That matters if conditions aren't ideal or the outage runs long. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The Apex 300 + 2×B500K'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 Apex 300 + 2×B500K, or is the Elite 320 the only portable option?
Neither is "portable" in any hiking sense. The Elite 320 (75 lbs) and the Apex 300 + 2×B500K (282.2 lbs) are both appliances you place and leave. The 207.2-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 Apex 300 + 2×B500K accepts 2,400W vs the Elite 320's 1,000W 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 7.7 hours for the Apex 300 + 2×B500K and 4.6 hours for the Elite 320. That gap widens on cloudy days, when the Apex 300 + 2×B500K'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 Apex 300 + 2×B500K's advantage is substantial.
"6,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the Apex 300 + 2×B500K (6,000 cycles) lasts 16.4 years at daily use, 58 years at weekend use (twice a week), or 250 years at twice-monthly camping trips. The Elite 320 (3,000 cycles): 8.2 years daily, 29 years weekends, or 125 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 13,004.8Wh unit becomes a ~10,404Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
What if I need more capacity than the Elite 320's 3,200Wh later?
The Elite 320 is sealed at 3,200Wh, so if you expect your needs to climb, the Apex 300 + 2×B500K is the more future-proof pick: it starts at 13,004.8Wh and adds BLUETTI-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 3,200Wh comfortably covers your loads, the Elite 320 is a complete unit, not a downgrade.
Bottom line: should I buy the Apex 300 + 2×B500K or the Elite 320?
We'd pay the premium for the Apex 300 + 2×B500K. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The Elite 320 is still solid if budget is the priority, but the Apex 300 + 2×B500K will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
