EcoFlow vs Jackery vs Bluetti — read the Wh label

Six official sheets, two size bands, read on 2026-10-21. The job is to turn a printed watt-hour label into energy at your loads. There is no winner and no hands-on test on this page.

Usable Wh from the printed label

The drawing uses a round 1,000 Wh label so the factors are easy to see. The six shop labels below are not 1,000 Wh. Apply the same two products. Round the delivered watt-hours once, with Math.round. Days later in this page divide the exact product, not that rounded watt-hour.

On a phone, swipe the tables sideways.

1,024 × 0.90 = 921.6 → 922 Wh on 12 V. 1,024 × 0.81 = 829.44 → 829 Wh on AC.

DELTA 2 Max and the AC200L print the same 2,048 Wh, so these two rows match. Explorer 2000 v2 prints 2,042 Wh, six watt-hours lower on the label. 6 × 0.81 = 4.86 Wh on the AC product before rounding. Chemistry, cycle endpoint, solar limits, car-charge limits, and expansion are the lines that still differ. The ~1,000 Wh class on this site runs from 513 Wh through 1,152 Wh, so 1,152 Wh is the class ceiling. 2,042 Wh and 2,048 Wh sit in the 1,153 Wh and up band.

What each sheet actually prints

All six base units print a LiFePO4 (LFP) cell. Cycle counts are not one test: EcoFlow’s manuals stop at 80%+, the Jackery sheets stop at 70%+, and the two BLUETTI product pages stop at 80% of original capacity. A higher count with a lower leftover percent is a different claim. The LiFePO4 vs NMC page is the chemistry primer. These six base sheets do not include an NMC station. The EcoFlow extra-battery page does: it lists a 2,016 Wh pack, chemistry NCM, 800 cycles to 80%, as applicable to DELTA 2. The station’s LFP line does not carry over to that pack. Day counts below stay on the base labels.

Continuous watts are the holding number. Surge, X-Boost, and Power Lifting are other lines. Jackery’s FAQ calls the short number “Maximum Instantaneous Output Power.”

Charge limits, the 12 V port, and expansion

Solar input fails if any one of watts, voltage, or current is outside the line. Car-outlet amps run a 12 V load. Car-charge amps, or watts, are what the station draws from the vehicle. A millisecond figure is the sheet’s switch claim. It is not a 0 ms UPS, and it is not a test performed here.

The van guide cites the CFX3 35 rated DC input of 7.5 A. At 12 V that rating is 90 W. Every 12 V outlet in the table prints 10 A. 7.5 A is under 10 A. EcoFlow’s shared cap is 126 W, and 90 W is under 126 W. Jackery’s pass-through line prints 120 W max on that port, and 90 W is under 120 W. Those are rating comparisons. They do not show that the compressor starts, and they do not clear a shared-port load beside the fridge.

The manuals print their own runtime shortcuts. This page does not use them. The AC180 manual’s small-load example is capacity × 90% × 85% ÷ (load + about 15 W), and its worked line is about 17 hours for a 40 W refrigerator. The AC200L manual’s example uses 95% depth of discharge, inverter efficiency over 93%, and about 12 W of self-consumption. WattNeeds keeps η, DoD, and buffer apart. The Explorer 1000 v2 FAQ prints standby power consumption of 18 W. That 18 W is not subtracted here. A Jackery runtime article that used to describe capacity × 0.8 returned HTTP 404 on 2026-10-21, so this page does not cite it.

Rainy camping weekend, fridge on 12 V

Same stack as weekend camping and rainy weekend. Solar = 0. The fridge row is the 320 Wh/day planning band, not the CFX3 282 Wh/day test point. Laptop 70 W × 2 h = 140 Wh. Lights 10 W × 5 h = 50 Wh. Phones 60 Wh. Total at the loads: 570 Wh/day.

Fridge on the 12 V port (320 Wh, η = 1.00) and phones on USB (60 Wh, η = 1.00). Laptop and lights on AC (190 Wh, η = 0.90). Battery draw per day is 380 + 190 / 0.90 = 591.111… Wh. Days = (nameplate × 0.90) / 591.111…. The all-AC column is the rainy-weekend path, every load on the inverter: days = (nameplate × 0.81) / 570.

Worked DELTA 2 row, mixed path: 1,024 × 0.90 = 921.6. 921.6 / 591.111… = 1.559098, shown as 1.559 days. Half-up to three decimals. Do not divide the rounded 922 Wh by 591.111….

The buffered plans are the weekend-camping results: mixed one day 755 Wh (exact 755.309), mixed two days 1,511 Wh (exact 1,510.617), all-AC two days 1,619 Wh. “Covers” means the printed label is at least that buffered nameplate. The ~1 kWh labels cover one mixed day and miss two mixed days with solar at zero. The 2,042 Wh and 2,048 Wh labels cover the 1,511 Wh plan and the 1,619 Wh all-AC plan (2,042 − 1,619 = 423 Wh of label above that plan). A 1,000 Wh round label on the rainy page is 1.4 days at one decimal of 810 / 570 = 1.421. These rows use the printed labels, so they are not that 1.4.

Home outage essentials

Scenario A on home outage, AC plugs only. Router 20 W × 24 h = 480 Wh. LED lamps 40 W × 6 h = 240 Wh. Phones and laptops allowance 150 Wh. Total 870 Wh/day. One buffered day is 1,235 Wh. Two buffered days are 2,470 Wh. Days here are (nameplate × 0.81) / 870. Buffer is not applied on the way down.

The 1,152 Wh label’s runtime check crosses one day (1.073) and still misses the buffered plan by 1,235 − 1,152 = 83 Wh. Shop the buffered nameplate. The runtime column is the check with the buffer left off.

Scenario B on that guide adds the cited 434 kWh/year fridge label, 1,189 Wh/day, for 2,059 Wh/day and a one-day nameplate of 2,923 Wh. Every label in this table is under 2,923 Wh. Days at 2,059 Wh on AC: 1,024 Wh lasts 0.403 day, 1,070 Wh lasts 0.421 day, 1,152 Wh lasts 0.453 day, 2,042 Wh lasts 0.803 day, and 2,048 Wh lasts 0.806 day. A ~2 kWh base unit is under one day of that stack. HVAC, a well pump, a range, and a transfer switch stay off this page, same as the home-outage guide. The DELTA 2 Max product page mentions a transfer switch for partial home backup. This page does not repeat that procedure.

Parked van day, plus Starlink Mini

The mild parked day on van daily Wh is 635.8 Wh at the loads, all on 12 V or USB in that guide: CFX3 35 test point 282 Wh, one fan 25.2 Wh, four pucks 44 Wh, two phones 40 Wh, one laptop recharge 52.6 Wh, router ceiling 192 Wh. The Starlink guide sizes the Mini at the top of its sheet average, 40 W × 8 h = 320 Wh. Eight hours is that guide’s planning pick. The sheet average band is 25–40 W, and the input line is 12–48 V, 60 W max.

All-DC day: 635.8 + 320 = 955.8 Wh at η = 1.00. One-day buffered nameplate: 955.8 × 1.15 / 0.90 = 1,221.3 → 1,221 Wh. Split day: the van loads stay on 12 V / USB and the Mini uses its included AC supply. Battery draw = 635.8 + 320 / 0.90 = 991.355… Wh. Passes: 635.8 × 1.15 / 0.90 = 812.411 (the van guide’s 812 Wh) and 320 × 1.15 / 0.81 = 454.321 (the Starlink guide’s 454 Wh). Exact sum 1,266.732 → 1,267 Wh. The rounded passes add to 812 + 454 = 1,266. Add the exact passes first.

60 / 12 = 5 A at the Mini’s 60 W input maximum if the source is 12 V. 5 A is under the 10 A printed on these 12 V outlets. That comparison does not choose a connector. The Starlink guide’s rule stands: use the DC cable in the Mini kit, or the included AC supply. This page does not splice a cable. A station USB-C port at 100 W is the accessory-port method on the Starlink page, not this 320 Wh row.

Worked all-DC DELTA 2 day: 1,024 × 0.90 = 921.6. 921.6 / 955.8 = 0.964218, shown as 0.964 day. The 1,152 Wh label’s runtime crosses one all-DC day (1.085) and is still 69 Wh under the 1,221 Wh buffered plan. Moving the Mini onto the AC supply shortens every row, because that 320 Wh then pays η = 0.90. Solar credit is zero, same as the van guide.

What these rows leave open

None of the day counts start a compressor, hold a kettle, or prove a router stays up through a switch. Continuous watts have to cover what is on together. Read surge, X-Boost, and Power Lifting as separate lines. Re-read the sheet that ships in the box if the model number differs, including AC180 versus AC180P (the product page prints 1,440 Wh for AC180P). Region columns differ: the AC180 manual’s EU voltage is not the US 120 V column used here, and the Jackery figures are the US FAQ rows dated above.

Wh calculator — one η per pass. 12 V and USB: set inverter efficiency to 1.00. AC outlets: leave η at 0.90. nameplate = (Wh/day × days × 1.15) / (0.90 × η).
