The Ultra’s 3,072Wh is a ceiling. The Apex 200’s 2,560Wh is a floor.
The EcoFlow DELTA 3 Ultra gives you more on day one: 3,072Wh, 3,600W, a 7,200W surge rating, a switchover under 10ms and a 25dB rating at 600W. It stays that size for life and takes 800W of solar. The BLUETTI Apex 200 starts at 2,560Wh and 3,200W, but takes up to six expansion batteries and 3,000W of solar, has a 12V/30A Anderson port, and fits in less than half the space at 59.3 lb. If 3kWh will always be enough, the Ultra is the simpler pick: more output, more surge and a faster switchover from one box. If your system will grow, or it lives in an RV, look at the Apex 200.
Below: every difference with numbers, a 20-second calculator for your own gear and eight modeled situations. No full independent review of the Apex 200 exists yet, so its side comes from BLUETTI.
Prices $200 apart today. The DELTA 3 Ultra holds 512Wh more, delivers 400W more, has the higher surge rating and the faster switchover. The Apex 200 weighs 12.8 lb less, takes 2,200W more solar, has a 12V/30A Anderson port and is the only one you can expand.
- you’ll add batteries later
- you run over 800W of solar
- your RV wants 12V/30A
- you need surge for motors
- you want a 10ms switchover
- 3kWh will stay enough
The six differences that decide it
Both are 120V LFP stations with 20A outlets, a TT-30, USB-C up to 140W and a 12V socket. These six gaps decide it.
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 2,176Wh usable on the Apex 200 and 2,611Wh on the DELTA 3 Ultra; nobody has published a measured figure for either.
Appliance for appliance, the Ultra lasts 20% longer than the Apex 200.

The price gap, in numbers
The EcoFlow DELTA 3 Ultra costs $200 more than the BLUETTI Apex 200 and adds 512Wh: that is $0.39 per extra Wh, against $0.43 per Wh for the Apex 200.
Prices refresh daily from BLUETTI US and EcoFlow US.BLUETTI rates the Apex 200 at 6,000+ cycles to 70%; EcoFlow publishes no cycle count for the Ultra, only an estimated 10 years, so a cost-per-cycle card would not compare like with like. One B300K takes the Apex 200 to about 5.3kWh and lifts its output to 3,600W. Prices move often; our engine refreshes them daily.
Eight modeled situations, worked out
Same formula as the calculator above: 85% of the rated capacity, no extra battery unless stated. The fridge averages 60W, about 525kWh a year.
24-hour outage, essentials only
The Apex 200 lands just short of a day, the Ultra a few hours past it. Only the Apex 200 can reach a second day, with an expansion battery.
Microwave, coffee maker and space heater together
The Ultra sits right at its rating. The Apex 200 alone is over: BLUETTI’s manual allows 3,360 to 3,840W for 2 minutes only, and rates it at 3,600W with an expansion battery. Drop one appliance and both cope.
Starting a motor
EcoFlow lists a 7,200W surge for the Ultra. BLUETTI’s manual gives the Apex 200 3,840 to 4,800W for 10 seconds, or 4,320 to 5,400W with an expansion battery. The Ultra has more margin on paper, so compare your motor’s start-up draw with both figures.
RV with a 30A inlet and 12V gear
Both take the 30A cord directly. The Apex 200 adds a 12V/30A Anderson port next to its 12V socket; EcoFlow’s table lists no Anderson port on the Ultra, only the 126W car socket. Both charge while you drive with an accessory.
Refill from solar, each at its maximum
With a big array the Apex 200 refills in a morning. With 800W of panels the gap shrinks to about 4.6 h against 5.5 h, so the 3,000W only pays if you own the panels.
Keeping a router and a PC on when the grid drops
EcoFlow lists under 10ms, and the Ultra’s 140W USB-C supports HID. The Apex 200 switches within 15ms, but its UPS mode is off by default, and BLUETTI’s manual says it is not for data servers or workstations. For a PC, the Ultra is the better fit.
CPAP in a bedroom
About a week on either. EcoFlow rates the Ultra at 25dB or less at 600W; BLUETTI’s 50 dB is a maximum, so neither figure tells you how a 40W load sounds. Check with your device maker before relying on a UPS mode for medical gear.
Moving it
The Apex 200 is 12.8 lb lighter and less than half the volume, but BLUETTI calls it a two-handed carry. The Ultra is bigger and heavier, with rear wheels for flat floors. Stairs favor the Apex 200.
Nine more differences, the spec sheet and the box
Smaller gaps that rarely decide the purchase, then the full specifications and what ships in the box.

Every port, side by side
Apex 200
DELTA 3 Ultra
Practical consequence: the Ultra has one more 20A outlet and three USB-C, though its two 45W ports share 45W. The Apex 200 has two full USB-C, two USB-A and a 12V/30A Anderson port, plus a battery port the Ultra doesn’t have.
08 · NoiseNoise: Apex 200 vs Ultra
EcoFlow rates the EcoFlow DELTA 3 Ultra at 25dB or less at 600W, at 1 m and 77°F. BLUETTI’s US manual gives the BLUETTI Apex 200 50 dB max. One is a 600W rating, the other a ceiling, so neither wins yet, and nobody has published a measurement of either.
Brand figures only, not like for like.Every figure we found, with its source
Measured by a tester Brand figure
- EcoFlow’s figure is for a 600W load; expect more fan noise above it. On the Apex 200, Silent mode caps AC input at 600W.
Cold and heat: Apex 200 vs Ultra
The BLUETTI Apex 200 runs colder, down to −4°F against 14°F. The EcoFlow DELTA 3 Ultra takes more heat, up to 113°F against 104°F. Neither charges below 32°F.
Figures from the BLUETTI US user manual and the EcoFlow US DELTA 3 Ultra specs.- Keep both above 32°F while they charge, in a cold garage or RV.
- Keep the Apex 200 under 104°F in a hot rig; the DELTA 3 Ultra has 9°F more room.
App, UPS and smart features
The EcoFlow DELTA 3 Ultra switches over faster, under 10ms against within 15ms, and connects to a transfer switch or inlet box. The BLUETTI Apex 200 is the only one that takes extra batteries, and adds smart outlets.
Each uses its brand’s app; both can charge on lower-rate hours.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Can you add a battery later? The BLUETTI Apex 200 takes up to six batteries, 33.28kWh with B500K; EcoFlow lists 0 scalability for the EcoFlow DELTA 3 Ultra.
Does it connect to a home panel? EcoFlow lists a manual transfer switch and an inlet box for the EcoFlow DELTA 3 Ultra; BLUETTI lists no panel input for a single BLUETTI Apex 200, only a two-unit Hub A1 bundle with a home kit.
Does it work as a UPS? The BLUETTI Apex 200 switches within 15ms once you set UPS mode in the app; BLUETTI’s manual says it is not for data servers or workstations. The EcoFlow DELTA 3 Ultra lists under 10ms.
Can it run a heater or kettle above its rating? X-Boost supports heating loads up to 4,600W on the EcoFlow DELTA 3 Ultra. Power Lifting on the BLUETTI Apex 200 accepts heating loads up to 5,400W, is off by default, and real output stays 3,200W.
Can it charge off-peak? Both schedule charging on lower-rate hours: TOU mode on the BLUETTI Apex 200, timed missions on the EcoFlow DELTA 3 Ultra.
Does it prepare for storms? The BLUETTI Apex 200 alerts you and charges only once you allow it; the EcoFlow DELTA 3 Ultra’s Storm Guard triggers AC charging ahead of severe weather after you activate it in the app.
Warranty and support
Both reach 5 years, but the BLUETTI Apex 200 lists them outright. The EcoFlow DELTA 3 Ultra has 3 years, plus 2 more once registered in the EcoFlow app.
A small edge to the Apex 200: no extra step is listed.Subject to each brand’s warranty terms and eligibility.
BLUETTI rates the Apex 200 at 6,000+ cycles to 70% of capacity. EcoFlow US doesn’t publish a cycle rating for the DELTA 3 Ultra, only an estimated 10 years of use from internal simulation.
- Keep the warranty card that ships with the Apex 200.
- Register the DELTA 3 Ultra in the EcoFlow app to get the extra 2 years.
What reviewers report
We have not had these two units in hand. As of November 4, 2026, no full independent review of the Apex 200 had been published. We found no full independent test of the base DELTA 3 Ultra either; reviews we found cover the Ultra Plus. Every figure on this page comes from BLUETTI’s US page and manual and EcoFlow’s US page, attributed as such.
Practical limits before you buy
- The Apex 200’s surge is short. BLUETTI’s manual gives 3,360 to 3,840W for 2 minutes and 3,840 to 4,800W for 10 seconds. Power Lifting’s 5,400W is for heating loads only, is off by default, and real output stays 3,200W.
- The DELTA 3 Ultra can never be expanded. If you want EcoFlow and room to grow, the Ultra Plus adds a battery port, up to 11kWh, 1,600W of solar and an Anderson port.
- The Apex 200’s 3,600W needs an expansion battery connected. On its own it stops at 3,200W, and a bigger system stays at 3,600W.
- The Apex 200’s 80% in 45 minutes needs Turbo and an optional cable. Turbo’s 3,200W goes through the P050A port, and its TT-30P or 14-50P cable is sold separately. The included 15A cable stops at 1,800W.
- The Apex 200’s UPS mode is off by default. Set it in the app. BLUETTI’s manual says it is not for data servers or workstations.
- The Apex 200’s high-voltage solar input runs 60 to 280V. Rooftop arrays must stay within its voltage, current and power limits.
- The DELTA 3 Ultra has no Anderson port. Its 12V output is the 126W car socket.
- Register the Ultra in the EcoFlow app to get the extra 2 years of warranty.
- Neither does 240V. Both are 120V only.

How we compared and sources
Research-based comparison. We have not had either unit in hand, and no full independent review of the Apex 200 existed on November 4, 2026. Specs come from the BLUETTI US Apex 200 product page and US user manual, and from the EcoFlow US DELTA 3 Ultra page. Prices and availability were checked on November 4, 2026.
- Specs: BLUETTI US, Apex 200 product page and its US user manual (V1.0), read on November 4, 2026, and EcoFlow US, DELTA 3 Ultra with its specs and Basic vs Plus table, read on November 3, 2026.
- Size and weight math is ours: 59.3 against 72.1 lb, 36.2 against about 81 L.
- Two EcoFlow conflicts: page text mentions an Anderson port, but its Basic vs Plus table gives the Ultra none, so we follow the table. The table lists 1,600W generator charging, the page text 1,800W. BLUETTI’s US user manual rates 3,600W with an expansion battery; its product page adds active AC or solar input. We use the manual.
- Runtime = capacity × 0.85 ÷ watts. Solar harvest = min(panel watts, max input) × sun hours × 0.70. Cost per lifetime kWh = price ÷ (cycles × capacity in kWh).
2,560Wh that grows to 33.28kWh with 3,000W of solar, against 3,072Wh and 3,600W with a 7,200W surge that stay as they are.
