Jackery vs EcoFlow: Which Portable Power Station Is the Best Deal Right Now?

Hook: Hate wasting time hunting deals only to get an undersized power station?

If you're juggling flash sales, confusing specs and coupon codes while trying to pick a backup battery that actually covers your needs, you're not alone. Two of the most-talked-about portable power stations in early 2026 are on unusually low-price rotations: the Jackery HomePower 3600 Plus (exclusive low from $1,219) and the EcoFlow DELTA 3 Max (flash sale at $749). This guide cuts through marketing, gives numbers you can trust, and helps you decide which model is the better long-term value for your use case.

Quick verdict (so you can act fast)

Short answer: If you need maximum kWh for whole-home backup and long-term value per watt-hour, the Jackery HomePower 3600 Plus typically wins. If you want the best up-front price for portable, fast-charging power for camping, vanlife or short outages, the EcoFlow DELTA 3 Max at $749 is the smarter bargain right now.

Below we break down price-per-Wh math, long-term cost (cycle life & warranty), real-world runtimes and the practical tradeoffs — plus actionable buying steps to lock in the best deal while these sales last.

Why this comparison matters in 2026

Battery and inverter tech matured dramatically through 2024–2025. By late 2025 and into 2026 we saw three trends that matter to buyers:

• LFP adoption: More mid- and high-tier power stations use lithium iron phosphate cells for longer cycle life and safer thermal profiles.
• Sharper price competition: Post-pandemic supply normalization and higher LFP production pushed street prices down; flash sales are more common.
• Software & integration: OTA firmware, (bi-)directional charging and smarter solar input handling are becoming table stakes.

Those trends make the question less about brand loyalty and more about what you’ll actually use the unit for over the next 3–7 years — whether that’s stationary whole-home support, weekend events or outfitting a touring rig (see tips for weekend sellers and creators).

Current sale snapshot (Jan 2026)

Jackery HomePower 3600 Plus — exclusive low from $1,219 (or $1,689 bundled with a 500W solar panel). EcoFlow DELTA 3 Max — flash sale at $749 (second-best price). Prices recorded mid-Jan 2026.

How to compare: the three numbers that decide value

When evaluating a power station, focus on these metrics:

1. Usable battery capacity (Wh) — how many watt-hours you actually get.
2. Cost per usable Wh — simple price-to-capacity math for comparing value.
3. Long-term cost: cycles, warranty and efficiency — how much life you get before performance drops.

Additional important specs: continuous inverter output (W), peak/surge capability, charging speed, fast AC & solar charging compatibility and weight.

Price-per-Wh: straightforward math

To compare apples-to-apples we start with the sale prices above and the manufacturer-advertised capacities. For the Jackery the model name indicates roughly 3,600 Wh of capacity. EcoFlow's DELTA 3 Max is a mid-sized DELTA-series unit—manufacturers vary on the exact advertised Wh, so we'll show a conservative range (1,500–2,200 Wh) and run the math both ways. Always confirm the current spec on the retailer page before purchase.

Scenario math (sale prices applied)

• Jackery HomePower 3600 Plus: $1,219 / 3,600 Wh ≈ $0.34 per Wh
• EcoFlow DELTA 3 Max (example ranges):
  • If 1,500 Wh: $749 / 1,500 Wh ≈ $0.50 per Wh
  • If 2,000 Wh: $749 / 2,000 Wh ≈ $0.37 per Wh
  • If 2,200 Wh: $749 / 2,200 Wh ≈ $0.34 per Wh

Takeaway: at these sale prices, Jackery's higher kWh typically delivers a lower price-per-Wh — i.e., better raw energy bang-for-your-buck — unless the DELTA 3 Max model you find has an advertised capacity near the top of the range.

Real-world runtimes: what these numbers mean

Capacity is numbers on a page until you translate them into runtimes. Here are real-world examples using typical appliance draws.

Common draws (for estimates)

• Small fridge: ~100–180 W running
• Full-size refrigerator (cycling): average ~150–300 W — useful to compare against home battery backup systems
• CPAP machine: ~30–60 W — if you plan medical use, see notes on mobile clinic essentials
• LED lights + router + phone charging: ~30–60 W
• Portable induction cooktop or hair dryer: 1,200–1,800 W (needs high continuous and surge capability)

Example runtimes (approximate usable capacity assumptions)

• Jackery HomePower 3600 Plus (3,600 Wh usable):
  • Small fridge at 150 W: ~24 hours continuous
  • CPAP at 60 W: ~60 hours
  • Lights + router (50 W): ~72 hours
• EcoFlow DELTA 3 Max (assume 2,000 Wh usable):
  • Small fridge at 150 W: ~13 hours
  • CPAP at 60 W: ~33 hours
  • Lights + router (50 W): ~40 hours

These illustrative runtimes highlight why kWh matters for prolonged outages or powering multiple circuits. If you only need short runtime for weekend trips or small loads, the lower-cost DELTA 3 Max often makes sense.

Beyond raw capacity: cycle life, warranties and real cost per cycle

Price-per-Wh ignores how many full cycles the battery can deliver before degrading. That's where long-term value shows up.

• Cycle life: LFP chemistry commonly claims 2,000+ cycles to 80% capacity; NMC or hybrid chemistries typically show fewer cycles. More cycles = lower cost per cycle. (For broader market impacts and end-of-life economics, see battery recycling economics.)
• Warranty: Look for multi-year coverage with capacity guarantees (e.g., 70–80% after X years).
• Efficiency & inverter losses: Expect 85–95% round-trip depending on how aggressively the unit manages power and how often you use high-load outputs.

Actionable step: divide the sale price by (usable Wh × expected full cycles) to estimate $/Wh/cycle. For example, $1,219 / (3,600 Wh × 2,000 cycles) gives you a rough sense of long-term cost, then compare that to the DELTA 3 Max using its cycle rating.

Power delivery & features: where the EcoFlow often shines

EcoFlow historically pushes aggressive inverter and charging specs at compact sizes. That shows in features buyers care about:

• Fast AC & solar charging: EcoFlow models often support high input rates so you can recharge quickly from shore or panels.
• High power density: More W output per kg in mid-size units.
• Smart app control: Robust apps, OTA updates and integrations with home circuits or smart panels.

For users who prioritize quick recharge between outings or high AC surge power to start motors, EcoFlow's engineering focus can outweigh its smaller kWh.

Portability and deployment: pick your priority

If you'll move the unit frequently (camping, vanlife, events), battery weight and form factor matter as much as kWh. Larger-capacity units like the Jackery HomePower 3600 Plus are heavier and need more careful handling, while DELTA-series units from EcoFlow are often designed for easier transport (see hands-on field kits and reviews such as the NomadPack review for a sense of real-world portability tradeoffs).
