Two Major Sales, One Breakdown
Two of the biggest names in portable solar power are running fall sales right now. EcoFlow's Autumn Sale has member-only pricing with up to 62% off bundles. ALLPOWERS' Fall Power Sale runs Sept 8–30 with up to 65% off across their entire lineup.
We've tracked both brands' pricing all year. Here's what's actually worth buying — ranked by value, not just discount percentage.
1. EcoFlow DELTA 2 Max + 2×220W Solar — Best Overall Deal
This is the deal. You get the DELTA 2 Max (normally $1,299) plus two 220W bifacial solar panels (normally ~$900 each) for $1,599 total. That's less than the power station alone at full price. The DELTA 2 Max runs a full-size fridge, router, fans, and medical devices simultaneously. Add the panels and you're recharging from the sun in 3–4 hours.
- Runs: fridge, CPAP, router, fans, laptop, TV
- Solar recharge: ~3–4 hours with included 440W panels
- Expandable: up to 6,144Wh with extra batteries
- Battery life: 3,000+ cycles to 80% (LiFePO4)
2. ALLPOWERS P1800 — Best Mid-Range Value
This is a $1,060 power station for $439. The P1800 delivers 1,152Wh of LiFePO4 capacity with 1,800W output — enough for a mini fridge, CPAP, phone charging, and lights during a multi-day outage. At this price, you're paying less per watt-hour than almost any competitor.
- Runs: mini fridge, CPAP, phone charging, LED lights
- Cost per Wh: $0.38/Wh (outstanding value)
- UPS function: automatic switchover during outages
- Sale ends: September 30, 2026
3. EcoFlow DELTA Pro — Best Large Capacity
The DELTA Pro has been the portable power standard since launch. At $1,899 (down from $2,799), you're getting 3,600Wh of LiFePO4 storage with 3,600W output. That's enough to run a full-size fridge, window AC unit, and power tools. Expandable to 25kWh with extra batteries for whole-home backup.
- Runs: full-size fridge, window AC, power tools, medical devices
- Expandable: add up to 2 extra batteries (25kWh total)
- Smart home: integrates with EcoFlow Smart Home Panel
- Also available: DELTA Pro + 400W Solar at $2,399 (28% off)
4. ALLPOWERS R3500 — Best ALLPOWERS Flagship
ALLPOWERS' flagship goes head-to-head with the DELTA Pro at $475 less. The R3500 delivers 3,168Wh with 3,500W output — slightly less capacity but nearly identical output power. If brand loyalty isn't a factor and you want the most watts per dollar, the R3500 wins on pure value at this sale price.
- Runs: full-size fridge, power tools, window AC, medical devices
- vs. DELTA Pro: $475 cheaper, similar specs, less brand ecosystem
- Expandable: yes, with ALLPOWERS expansion batteries
- Sale ends: September 30, 2026
5. EcoFlow DELTA Pro Ultra — Best Whole-Home Backup
This is the Tesla Powerwall alternative you can buy online and install yourself. The DELTA Pro Ultra delivers 6.1kWh with 7,200W output — enough to power central AC, well pumps, and your entire home. Expandable to a staggering 90kWh. The 30% federal tax credit brings it to roughly $2,939, making it cheaper than a Powerwall with a 6-month waitlist.
- Runs: central AC, well pump, full kitchen, whole home
- Tax credit: qualifies for 30% federal ITC (~$1,260 back)
- No installer: ships to your door, plug and play

6. EcoFlow DELTA 2 Max — Best All-Rounder
If you don't need the solar panels from the bundle deal (#1), the standalone DELTA 2 Max at $1,049 is still a strong buy. 2,048Wh with 2,400W output handles everything short of central AC. The sweet spot between portability and power.
7. ALLPOWERS R600 — Best Budget Pick
Under $220 for a LiFePO4 power station that charges your phone 25+ times, runs a CPAP all night, and powers LED lights for days. The R600 is the entry point into solar backup — pair it with a 100W panel ($70 during the sale) and you have a self-charging emergency kit for under $300.

Should You Buy Now or Wait for Black Friday?
Buy now if:
- You're in a hurricane-prone area — September is peak season and stock sells out during storms
- You need the DELTA 2 Max bundle — the 62% off deal may not return
- You want the ALLPOWERS P1800 — 59% off is the deepest cut we've seen on this unit
Wait if:
- You're not in a rush and can gamble on a slightly deeper Black Friday bundle
- You want a product not currently on sale (BLUETTI, Jackery)
Our take: these prices are within 5–10% of last year's Black Friday deals. The DELTA 2 Max bundle at $1,599 is already at or below Black Friday 2025 pricing. If you need backup power before November, buy now.
