โšก Quick verdict (TL;DR): We tested both. For occasional outages + camping + RV trips, the EcoFlow Delta 2 wins on portability and fast charging.

Deep dive: EcoFlow Delta 2

The Delta 2 has been EcoFlow's "do-everything" mid-range since 2023, and firmware updates have kept it competitive in 2026. What it does well:

  • Genuinely fast recharge. 50 min from 0-80% on AC. When a storm is approaching and you've got a small window to top off, this matters.
  • Best app in the category. Real-time consumption, smart scheduling, push alerts. Hands down the most polished mobile experience among power stations.
  • Cheap solar ecosystem. EcoFlow's 110W and 220W panels offer the best price-to-watt ratio if you ever want to add solar.
  • Light (27 lbs). Significantly easier to haul to the campsite, trunk, or basement than the AC180.
  • Modular path. Add a Delta 2 Extra Battery later to double capacity. Plan for growth.

What's not great:

  • Base 1,024 Wh is light for multi-day outages without an extension battery.
  • Expansion batteries are pricey (~$499 each). If you know you'll need more than 1 kWh from day one, the AC180 makes more sense.

Deep dive: BLUETTI AC180

The AC180 is the favorite of off-grid forums and storm-prep communities in 2026. It costs less, packs more, and lasts longer. Pros:

  • More capacity per dollar. $0.61/Wh is the best value in its class โ€” beats Delta 2 ($0.78/Wh) and Jackery 1000 v2 ($0.75/Wh).
  • 3,500 cycles vs 3,000. If you cycle it daily, that's ~17 months extra real-world life.
  • True 20ms UPS. Sensitive to electronics like CPAP machines, desktops, or work-from-home rigs? This passes the test. Delta 2's 30ms EPS is fine for most but not for ultra-sensitive gear.
  • Power Lifting up to 2,700W. Runs space heaters, hair dryers, and resistive loads other units in this class can't.

What's not great:

  • Heavy (35 lbs / 16 kg). 8 lbs more than Delta 2 โ€” noticeable if you move it often or take it camping.
  • Not truly expandable. For growth path, look at AC180P (1,440 Wh) or jump to AC200L. Lacks Delta 2's modularity.

๐Ÿ† Final verdict

Occasional home backup + camping

EcoFlow Delta 2 (~$799). Hard to beat the combination of fast charge, lightweight, and best-in-class app for occasional use.

Best value buy

Storm prep / daily off-grid

BLUETTI AC180 (~$699). Cheaper, more capacity, longer lifespan, 20ms UPS. If you'll use it weekly or monthly, this is the smart money.

Budget alternative (~$599)

Anker SOLIX C1000 โ€” 1,056 Wh LiFePO4, charges 0-100% in 58 min, solid Anker support. Great if your budget caps at $600.

Whole-home base ($1,599)

EcoFlow Delta 2 Max โ€” 2,048 Wh, 2,400W output, expandable to 6 kWh. The right move if you want a serious backup system you can grow.

Frequently asked questions

A typical home refrigerator pulls about 80W average (compressor cycles on/off). Rough math: Delta 2 โ†’ 10-12 hours. AC180 โ†’ 11-13 hours. Pair either one with a 200W solar panel and you can essentially run a fridge indefinitely during a multi-day outage in daylight conditions.
Yes, both. A typical CPAP without humidifier uses 30-60W. Either unit will run a CPAP for 15-30+ hours on a single charge. For sensitive medical devices, the BLUETTI AC180's true 20ms UPS gives you slightly better protection during the switchover.
Maybe. A 5,000 BTU window AC pulls ~450W running but can surge to 1,200W on startup. Both units can handle that surge. Runtime: ~2 hours on Delta 2, ~2.5 hours on AC180. For longer AC runtime, look at the Delta 2 Max (2,048 Wh).
LiFePO4 (lithium iron phosphate) is safer (won't catch fire), lasts more cycles (3,000+ vs 500-800), and handles temperature extremes better. It's the standard for serious home backup. Both units compared here use it.
No. Both exceed the FAA limit (100 Wh per battery in carry-on). These are home/RV/car-trip products, not air travel.
Both offer 5-year manufacturer warranty. EcoFlow has stronger US presence (faster shipping, English-speaking support, easier RMA process). BLUETTI's US support has improved a lot since 2024 but EcoFlow still has the edge on customer service.
