Mango Power E vs EcoFlow DELTA Pro: 3.5 kWh-Class Home Backup Stations Compared

November 9, 2026
Mango Power E Main 123

Last updated: November 9, 2026. Every spec and price here comes from Mango Power’s US product pages for the Mango Power E and its 240V Power Kit, the Mango Power E user manual and mSocket Pro quick guide, EcoFlow’s US DELTA Pro product page, and EcoFlow’s DELTA Pro user manual, all read November 9, 2026. This is a spec comparison, not a hands-on test. We haven’t run either unit ourselves. Anything marked “arithmetic” is our math on the makers’ published figures. Prices and stock change often, so check the live listing before you buy.

The Mango Power E and the original EcoFlow DELTA Pro are close on paper: about 3.5 kWh of LiFePO4 battery, about 100 lb on wheels, and a path to 240 V by pairing two units. On November 9, 2026 both were still sold new on their makers’ US stores. The Mango Power E listed at $1,299 and the DELTA Pro at $1,799.

The short answer: the DELTA Pro has more AC output on paper (3,600 W rated vs 3,000 W, with a 7,200 W surge figure and X-Boost for heating loads up to 4,500 W), a longer published cycle rating to 80%, a 30 ms EPS switchover in its manual, and a bigger accessory system. The Mango Power E costs $500 less, has a wider-voltage 2,000 W solar input and 3,000 W AC charging at 120 V (with an extra cable), and a cheaper two-unit 240 V kit. Neither is simply “better”. It depends on your loads, your solar array, and whether you need 240 V.

Which one handles bigger loads?

On a single 120 V unit, the DELTA Pro has the higher published rating: 3,600 W continuous against the Mango Power E’s 3,000 W. That gap matters if you plan to run something like a window AC, a microwave, and a fridge at the same time.

  • Motor and compressor starts. EcoFlow publishes a 7,200 W surge figure. Mango publishes an overload table instead: up to 3,750 W for 5 minutes, up to 4,500 W for 60 seconds, up to 4,800 W for 10 seconds, and anything over 4,800 W for less than 40 ms. The two makers describe surge differently, so the numbers aren’t a clean head-to-head.
  • Heating loads. EcoFlow’s X-Boost lets the DELTA Pro run devices rated up to 4,500 W by lowering voltage, while rated output stays at 3,600 W. EcoFlow’s manual says it suits heating devices and doesn’t suit appliances with strict voltage requirements. Mango prints no X-Boost-style mode.
  • Computers and medical devices on wall power. EcoFlow’s manual gives a 30 ms EPS switchover and says not to use it for devices that need 0 ms UPS. Mango doesn’t print a switchover time in the spec table or manual we read, so confirm with Mango support before you count on it for a CPAP or a desktop PC. Our CPAP backup guide covers what to check.
  • Idle draw. EcoFlow says the DELTA Pro uses about 30 W on standby with AC output on. Over 24 hours that’s about 720 Wh, our arithmetic. Mango doesn’t publish a standby figure.

How do you get 240 V from each one?

Neither unit makes 240 V by itself. Both need a second unit and an accessory.

  • Mango Power E: two units joined by the E-Link port, with the mSocket Pro (rated 120/240 V, 30 A max output in its quick guide) or the mPanel Pro, give 240 V split phase at 6,000 W total (2 × 3,000 W). Mango’s 240V Power Kit (2 × Mango Power E + 1 × mSocket Pro, 7,066 Wh) listed at $2,599 on November 9, 2026. Mango’s manual says home backup through your panel needs the mPanel Pro.
  • EcoFlow DELTA Pro: two units joined by the Double Voltage Hub give up to 7,200 W. EcoFlow’s “2 × DELTA Pro + Double Voltage Hub” bundle listed at $3,398 and in stock on November 9, 2026. The bundle that adds a transfer switch was sold out that day. EcoFlow’s FAQ puts the hub’s peak at 9,000 W for tens of milliseconds.
  • Wiring into the house. Either way, a 240 V feed into a home panel needs a transfer switch or interlock installed by a licensed electrician. Read our transfer switch safety guide first. For a hardwired furnace blower, see our gas furnace guide.

The price gap on 240 V is the biggest money difference on the page: $2,599 for Mango’s two-unit kit against $3,398 for EcoFlow’s two-unit bundle, both makers’ own prices on November 9, 2026.

How fast do they recharge from the wall and from solar?

  • Wall, 120 V: Mango lists 3,000 W max AC input, 80% in 1 hour and 100% in 1.5 hours, but only with a 30 A fast-charging cable sold separately and the max AC input current set to 30 A. Its manual says the included cable is 15 A. The DELTA Pro lists 1,800 W at 120 V (about 2.7 hours) and 3,000 W on a 240 V circuit (about 1.8 hours).
  • Solar: the Mango Power E takes up to 2,000 W at 60–150 V. Its page says to connect at least two panels in series, supports up to three in series, and includes parallel cables. The 60 V floor rules out a single 12 V or 24 V panel. The DELTA Pro takes up to 1,600 W at 11–150 V and 15 A, so it accepts small single panels as well as long strings.
  • Other inputs: EcoFlow lists EV-station charging up to 3,400 W (about 1.7 hours), 12/24 V car charging, and its Smart Generator. Mango lists EV-charger input with an adapter and generator input.

How long will each one run a fridge, a router, or a well-sized load?

Neither maker prints a runtime formula on the pages we read, so the table below is plain arithmetic: battery Wh ÷ load watts. Treat it as a ceiling. Real runtime on AC will be lower because of inverter losses and standby draw. Mango prints an inverter efficiency of up to 88%, which would leave at most about 3,109 Wh usable on AC (our arithmetic). EcoFlow prints about 30 W of standby draw with AC on, which you’d add to your load.

Average loadMango Power E ceiling (3,533 Wh ÷ W)DELTA Pro ceiling (3,600 Wh ÷ W)
50 W (router, modem, lights)About 70.7 hAbout 72.0 h
100 W (fridge average)About 35.3 hAbout 36.0 h
300 W (fridge, lights, TV, fans)About 11.8 hAbout 12.0 h
1,000 W (microwave, space heater on low)About 3.5 hAbout 3.6 h

Fridges and freezers cycle, so their average draw is well below the running watts on the label. Our fridge and freezer runtime guide shows how to estimate it, and our space heater guide explains why heat empties a battery quickly.

Where do the makers’ own numbers disagree?

  • Mango warranty: the product page headline says “10-Year Warranty” for the CATL LFP battery, while the same page’s FAQ and the user manual both say 5 years. Get the warranty terms in writing before you buy.
  • Mango cycle wording: the spec table says 6,000 cycles to 70% capacity. The page copy also says “over 20 years lifespan”, based on one full cycle every 1.5 days.
  • DELTA Pro outlet count: the spec table says 5 AC outlets, and the output FAQ on the same page lists 4 × 20 A. The FAQ also prints “220V, AC 50/60Hz”, which reads like the international version. The US spec table and EcoFlow’s US charging note are 120 V figures.
  • DELTA Pro charging totals: the page advertises 6,500 W MultiCharge and says 1.9 hours with AC + solar at 3,000 W, while the FAQ says AC and DC charging together max out at 2,200 W.
  • DELTA Pro maximum capacity: the page says 21.6 kWh in one place and 21.5 kWh in the FAQ for two units with four Extra Batteries. The 25 kWh headline counts Smart Generator fuel too.
  • Cycle ratings use different end points: Mango rates to 70% remaining capacity and EcoFlow to 80% and 50%, so 6,000 vs 3,500 isn’t a like-for-like comparison.

Which one fits which buyer?

  • Lean toward the Mango Power E if price per kWh matters most, you have or plan a high-voltage solar string (60–150 V, up to 2,000 W), you want the cheaper two-unit 240 V kit, or you’ll buy the 30 A cable for 3,000 W wall charging.
  • Lean toward the DELTA Pro if you need more than 3,000 W on 120 V, want X-Boost for heating loads, need a published EPS switchover time, want to charge from small single panels, or want EcoFlow’s accessory system (Extra Batteries, Smart Generator, Double Voltage Hub, Smart Home Panel).
  • Look at newer models too. The original DELTA Pro has newer siblings. Our Anker SOLIX F3800 Plus vs DELTA Pro comparison and EcoFlow vs Anker SOLIX lineup guide cover them.

FAQ

Is the original EcoFlow DELTA Pro still sold new? Yes. On November 9, 2026 EcoFlow’s US store listed it at $1,799 and in stock. Several DELTA Pro bundles were sold out that day.

Can one Mango Power E or one DELTA Pro run a 240 V well pump or dryer? No. Each unit puts out 120 V on its own. Both makers need two units plus an accessory (Mango’s mSocket Pro or mPanel Pro, EcoFlow’s Double Voltage Hub) for 240 V.

Which charges faster from a normal outlet? On paper, the Mango Power E: 3,000 W and 100% in 1.5 hours, but only with Mango’s separately sold 30 A cable on a circuit that can supply it. On a regular 15 A outlet, both are limited by the circuit. The DELTA Pro lists 1,800 W and about 2.7 hours at 120 V.

Did you test these? No. This page compares the makers’ own published specs, read November 9, 2026.
