Whole-Home Backup Tester
Both carry the BLUETTI name, but they're built for different buyers. The Apex 200 + B300K (5,325Wh, 3,600W) and the EP500Pro (5,120Wh, 3,000W) come from different product lines with different engineering priorities and a $1,300 price gap. We'd buy the Apex 200 + B300K.
The Apex 200 + B300K holds 205Wh more than the EP500Pro β about 30 hours on a fridge against 29 β 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 Apex 200 + B300K if you want the unit that wins the head-to-head on balance. Go with the EP500Pro if its specific strengths below line up better with your use. 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 200 + B300K
With a massive 3,600W output, the Apex 200 + B300K can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 124.5 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 $0.41 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Lighter by 62.5 lb
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
- +Rated for 6,000 charge cycles β much longer battery lifespan
Trade-offs
- βVery heavy unit that may be difficult for one person to lift.
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
- +Longer warranty
Trade-offs
- βSignificantly heavier (+62.5 lbs), making it harder to move.
- βWeaker inverter (-600W) limits appliance compatibility.
- βVery heavy unit that may be difficult for one person to lift.
- βSealed capacity β the Apex 200 + B300K can add batteries to grow past 5,120Wh; this one can't.
- βShorter-lived battery β rated for 3,500 charge cycles vs the Apex 200 + B300K's 6,000, so it wears out sooner.
Will It Power Your Gear?

Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 Β· 2 nights Β· needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Scoring these two at a campsite is a category error: neither travels β the Apex 200 + B300K is 124.5 lbs and the EP500Pro 187 lbs, and at those weights they roll off a truck bed if they go anywhere at all. The 2,100Wh here is trivial for either β it's the going that doesn't happen. If you need power away from the building, you're shopping the wrong class.

Either unit
Both survive the blackout with similar margin, and both list a UPS mode β compare their stated switchover classes, and remember those are manufacturer ratings, not measurements.

SCN-03 Β· 8 hours Β· needs 320Wh
CPAP Overnight
Sleep therapy without interruption β 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 β capacity isn't the question here. What would separate them is fan noise, but neither maker publishes a fan-noise figure, so there's nothing to hold either of them to. Only the Apex 200 + B300K is still sold, so for a new buy it takes this by default; the EP500Pro is worth weighing on weight and fan noise only if you already own one.
Battery budget usedlower = more headroom
LOADΒ Β CPAP Machine 40WΓ8h
SCN-04 Β· 8 hours Β· needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Either unit
Both power your workstation all day without strain. At these utilization levels the real difference is USB-C for direct laptop charging β 140W on the Apex 200 + B300K against 100W β which beats the inverter for convenience and wastes less energy.

Neither unit
Scoring these two at a tailgate is a category error: neither travels β the Apex 200 + B300K is 124.5 lbs and the EP500Pro 187 lbs, and at those weights they roll off a truck bed if they go anywhere at all.

Van Life Daily
A full day of mobile living β the ultimate endurance test
Neither unit
This scenario needs 4,685Wh and neither unit quite finishes it. The Apex 200 + B300K lands within 4% of it β close enough that trimming one appliance, or accepting a shorter evening, gets you there on the day.

See the full weight table and data sourcing on our methodology page βClass ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, Apex 200 + B300K rates 4.4/5 (62nd percentile of 22 Home Backup-class units), and EP500Pro rates 3.5/5 (10th percentile of 22 Home Backup-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 Apex 200 + B300K (124.5 lbs) is spread across its boxes β no single lift, but nothing you reposition on a whim. The EP500Pro (187 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 63 lb difference, and it is paid once β getting the heavier one into position, not every time you move it.
EP500Pro: Fixed Capacity
The EP500Pro is sealed at 5,120Wh β fine if that covers you, but it's the ceiling. By contrast the Apex 200 + B300K can add expansion batteries, so if your needs grow past 5,120Wh it has somewhere to go the EP500Pro doesn't β and at this size that path genuinely points toward partial-home backup.
UPS Switchover: β€15ms vs β€20ms
Both list a UPS mode, at different rated speeds. The Apex 200 + B300K is rated β€15ms β fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The EP500Pro is rated β€20ms β 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.
Battery Lifespan in Real Years
The Apex 200 + B300K is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. After hitting the cycle limit, the battery doesn't die β it drops to ~80% of original capacity, which is still very usable.

Analyst note
The EP500Pro 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 Apex 200 + B300K works out at $0.07/kWh over its rated life. If you already own the EP500Pro, the hardware comparison still holds: over its rated life the Apex 200 + B300K delivers about 31,949 kWh and the EP500Pro about 17,920 kWh.
Growth path
Apex 200 + B300K
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit β useful if your needs may climb past 5,325Wh.
Accepts up to 3,000W 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.
EP500Pro
FIXED CAPACITYFixed at 5,120Wh β 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.
Realistic full solar rechargeat 70% of rated panel output β see methodology
Analyst note
Growth only counts if you can still buy in, and the EP500Pro is no longer sold (BLUETTI points owners to the Apex 300 + B300K). That leaves the Apex 200 + B300K: it starts at 5,325Wh and takes BLUETTI expansion batteries, so the ceiling moves if your needs do. The EP500Pro's fixed 5,120Wh still matters if you already own one, but it isn't a reason to pick it over the Apex 200 + B300K.
The Bottom Line
The full picture comes down to this. The Apex 200 + B300K 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 β if the EP500Pro wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the Apex 200 + B300K nor the EP500Pro feels like the right fit, your power needs probably sit outside what these two target. For lighter use β weekend camping or phone/laptop charging β you'd be overpaying for capacity you'll rarely tap. Consider a unit in the 500β1,500Wh 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.
Can I actually carry the EP500Pro, or is the Apex 200 + B300K the only portable option?
Neither is "portable" in any hiking sense. The Apex 200 + B300K (124.5 lbs) and the EP500Pro (187 lbs) are both appliances you place and leave. The 62.5-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 200 + B300K accepts 3,000W vs the EP500Pro's 2,400W 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 2.5 hours for the Apex 200 + B300K and 3.0 hours for the EP500Pro. That gap widens on cloudy days, when the Apex 200 + B300K'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 200 + B300K's advantage is substantial.
"6,000 vs 3,500 cycles" β what does that actually mean for me?
In real years: the Apex 200 + B300K (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 EP500Pro (3,500 cycles): 9.6 years daily, 34 years weekends, or 146 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 5,324.8Wh unit becomes a ~4,260Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
What if I need more capacity than the EP500Pro's 5,120Wh later?
The EP500Pro is sealed at 5,120Wh, so if you expect your needs to climb, the Apex 200 + B300K is the more future-proof pick: it starts at 5,324.8Wh and adds BLUETTI-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own β if 5,120Wh comfortably covers your loads, the EP500Pro is a complete unit, not a downgrade.
Bottom line: should I buy the Apex 200 + B300K or the EP500Pro?
We'd buy the Apex 200 + B300K. The EP500Pro is no longer sold, so there is no price to weigh it against; the comparison on this page still helps if you own one.
