How we evaluated these units

Our comparison uses the buyer pain points for value shoppers: clear numeric specs, real‑world runtimes, charge strategies, portability, warranty & service, and current prices/deal windows. We reference recent 2025–2026 trends — wider LFP adoption, faster AC + solar hybrid charging, and improved firmware for battery management — to judge future reliability and resale value.

Side‑by‑side: key attributes at a glance

Below is a concise comparison focused on metrics that matter to buyers. Where specific numbers vary by sub‑model or bundle, we explain the practical effect and how to check what matters to you.

Capacity (usable Wh)

Why it matters: Watt‑hours (Wh) tell you how long a battery can run a device. For decision‑making, calculate the appliance power (W) × hours to choose Wh size.

Jackery HomePower 3600 — Marketed as a multi‑kWh unit in the 3,000–3,600 Wh class ("3600" in the model name indicates ~3.6 kWh). That capacity positions it as a small home backup battery rather than a day‑trip power bank.
EcoFlow DELTA 3 Max — Positioned in the mid‑range portable class. Manufacturers have pushed DELTA 3 variants into roughly the 1,000–2,000 Wh class for a mix of portability and runtime. The "Max" variant increases usable energy and output relative to the base model but remains targeted at RVs and mobile use.
Practical tip: Multiply appliance watts × hours, then add a 20–30% buffer for inverter losses and inefficiency when mapping Wh needs.

Inverter power (continuous & surge)

Why it matters: Inverter wattage governs what appliances you can run simultaneously. Continuous rating is what you can sustain; surge rating handles motor starts (fridges, pumps).

Jackery HomePower 3600 — Built for higher continuous loads typical for home backup: this class typically supports multi‑kW continuous output and generous surge capacity to start compressors and pumps. That makes it suitable for powering multiple household circuits.
EcoFlow DELTA 3 Max — Designed for high peak output relative to size, excelling at short bursts (suitable for AC units and power tools in many cases), while keeping continuous output tuned to RV and outdoor use. The tradeoff is fewer sustained kilowatt hours versus a multi‑kWh home battery.
Practical tip: For refrigerators, check starting wattage and ensure the inverter surge rating covers it. For medical devices or heaters, prioritize continuous wattage and stable sine‑wave output. See our companion piece on powering travel tech, inverters and battery banks for charger and inverter specifics.

Charge time and real‑world recharge options

Why it matters: Fast recharge reduces downtime during rolling outages or between campsite stops. Look at AC wall charge time, solar input limits, and whether the unit supports AC + solar simultaneous charging.

Jackery HomePower 3600 — Multi‑kWh units typically take longer to charge from AC but can charge faster if they support high‑power AC input or add‑on wall chargers. Bundles that include 500W panels (current bundle price noted below) accelerate off‑grid recharge but will still take multiple hours with a single panel.
EcoFlow DELTA 3 Max — EcoFlow has prioritized fast AC + solar charging in its recent models, often using combined AC + solar or dual AC ports to reach industry‑leading recharge speeds. That makes DELTA 3 Max attractive for users who need quick turnaround between uses. Our field tests and portable power & lighting kit reviews document real charge times and recharge strategies.
Practical tip: If you plan overnight home backup, fast recharge is less critical. If you plan daily mobility (RV, events), prioritize units with faster wall and solar charging and look for simultaneous input capability.

Solar compatibility and expandability

Solar compatibility varies by input voltage, max input wattage and whether the unit accepts multiple panels in series/parallel. In 2026, look for these features:

High MPPT input limits (>=500W) for faster solar recharge;
Compatibility with standard MC4 panels or bundled proprietary panels;
Ability to chain or stack batteries for multi‑kWh systems (more common in home‑oriented models).

Jackery HomePower 3600 is sold in bundled packages with panels (e.g., HomePower 3600 Plus + 500W panel). This suggests factory support for larger solar arrays and longer off‑grid runtime. EcoFlow DELTA 3 Max prioritizes high MPPT throughput and modular charging speed, though expandability beyond the single unit differs by model. See our field review of solar-powered cold boxes and battery strategies for related panel and input-limit guidance.

Portability: weight, form factor, and use cases

Why it matters: If you plan to move the unit frequently — camping, tailgates, or mobile work — weight and handles matter as much as raw capacity.

Jackery HomePower 3600 — Multi‑kWh home units are heavier and bulkier. They’re ideal for semi‑permanent installation in a garage or basement, or as a stationary backup that is occasionally relocated.
EcoFlow DELTA 3 Max — Engineered for portability: smaller footprint, lighter weight, and easier to stow in a vehicle. Best where transportability and fast charge outweigh maximum stored energy. If portability is your top priority, also check compact charger and powerbank reviews such as our roundup of best budget powerbanks & travel chargers.
Practical tip: For rooftop or car trunk portability, check the actual weight — many values over 30–50 lb become impractical for one person to carry safely.

Warranty, battery chemistry and lifecycle

Why it matters: Warranty length and battery chemistry (LFP vs NMC) determine lifetime cost and reliability. Since 2024–2026, the industry has trended strongly toward LFP (lithium iron phosphate) because of long cycle life and thermal stability.

Jackery HomePower 3600 — Home‑grade units typically ship with multi‑year warranties and a focus on cycle life; check retailer details because some sale bundles include extended service plans.
EcoFlow DELTA 3 Max — EcoFlow has expanded warranties and service programs in 2025–2026 to support fleet and RV customers; verify exact years and cycle ratings (e.g., 2,000+ cycles at 80% DoD) when buying.
Actionable check: Look for explicit cycle guarantees and whether the warranty covers household use (not just recreational). For multi‑kWh units, prefer LFP chemistry or explicit high‑cycle claims. Also read the warranty fine print carefully and watch for deceptive returns & warranty abuse traps in reseller policies.

Real‑world use cases and sample runtimes

Below are practical scenarios and how each unit class performs. Use the included formulas to customize calculations for your devices.

How to calculate runtime (simple)

Runtime (hours) ≈ (Battery Wh × usable % / Appliance W) × efficiency factor (0.7–0.85). Assume 0.8 for modern inverters.

Use case: Short outage + fridge + lights

Scenario: Run a modern refrigerator (avg 80–200W running, 800–1,200W start), 4 LED lights (20W total) and charge phones for 6–8 hours overnight.
Jackery HomePower 3600: Multi‑kWh capacity handles this for 24+ hours depending on fridge cycles. Its surge capability is helpful for compressor starts. If you’re pairing a small fridge, review small-capacity refrigeration field notes like our small-capacity refrigeration review for starter-draw guidance.
EcoFlow DELTA 3 Max: Suitable for 8–12 hours depending on exact Wh and fridge efficiency; fast recharge helps if you can top up during the day with solar.

Use case: Weekend off‑grid for 2 people (lights, laptop, small fridge)

Scenario: 2 laptops (2 × 60W), small fridge (100W avg), lights (30W total), periodic coffee maker (800W for 5 minutes).
Jackery HomePower 3600: Excellent — you’ll have multiple charge cycles and headroom for appliances.
EcoFlow DELTA 3 Max: Strong option if you prioritize portability and fast solar recharge; pair with at least 400–600W of solar for day‑to‑day topping up.

Use case: Whole‑house short backup (partial circuits)

Scenario: Power essential circuits: fridge, router, lights, well pump in short rotation.
Jackery HomePower 3600: Built for this — choose it if you need sustained kilowatt output without running a gas generator.
EcoFlow DELTA 3 Max: Only if you limit loads to critical items and accept shorter run times or plan to recharge quickly via AC or solar.

Current deals (Jan 2026) and how to lock savings

Value shoppers have options right now, but timing and bundles matter:

Jackery HomePower 3600 Plus — Exclusive new low price from $1,219 for the station; HomePower 3600 Plus + 500W solar panel bundle at $1,689 (prices noted Jan 15, 2026). These bundle discounts significantly improve off‑grid value.
EcoFlow DELTA 3 Max — Flash sale price reached $749 (second‑best price at the time of the Jan 2026 flash sale). EcoFlow flash events often include accessory discounts (extra panels, carrying cases).

Deal strategy: If a multi‑kWh station falls into your budget via a flash sale, buy the larger unit. For portability needs, prioritize the fastest recharge unit even if smaller. Use price trackers (browser extensions, deal newsletters) to catch end‑of-season and post‑holiday clearances — EcoFlow and Jackery both run aggressive promotions around CES and early‑year inventory moves.

Advanced strategies buyers use in 2026

Recent trends (late 2025 to early 2026) changed how people configure portable power:

LFP adoption: Prioritize LFP chemistry where possible; it increases lifecycle and resale value.
Hybrid charging: Combine AC + solar simultaneously for dramatic recharge speed gains during limited sun windows.
Stacking & modular expansion: Use home‑grade units as base plus portable DELTA‑class units for surge or mobility — see pop‑up tech and hybrid showroom kits for modular power and touring setups.
Firmware & app integration: In 2026, smart BMS features (OTA updates, battery conditioning modes) are differentiators — favor manufacturers that push frequent firmware support.

Warranty fine print and service considerations

Value shoppers should read the warranty and service terms closely:

Does the warranty cover battery degradation (e.g., capacity below X% within Y years)?
Is on‑site support or depot repair available, or must you ship the unit back? Consider shipping cost and downtime.
Are replacement batteries or accessory panels readily available and reasonably priced?

Tip: If you plan to run the unit heavily (daily cycling), opt for the longer warranty and documented cycle ratings even if up‑front price is slightly higher.

Short list: who should buy which (decision framework)

Choose Jackery HomePower 3600 if you need multi‑kWh storage for long outages, want whole‑home partial backup, and can manage a heavier, station‑style unit.
Choose EcoFlow DELTA 3 Max if you want a portable, fast‑charging station for RVs, weekend camping, or frequent use with solar recharge opportunities.
Choose both if you want a hybrid approach: HomePower at home for sustained outages, DELTA 3 Max for mobility and quick top‑ups.

Actionable checklist before you buy

Calculate needed Wh: list devices, average W, and target hours; add 20–30% buffer for inverter losses.
Check continuous and surge inverter ratings vs your highest start‑draw device.
Verify solar input limits and whether the unit supports simultaneous AC + solar charging.
Confirm battery chemistry and cycle warranty (prefer LFP and 2,000+ cycle claims for heavy use).
Compare bundle value: included panels or cables can change total cost of ownership.
Set price alerts (deal newsletters, browser extensions) for scarce big drops — the Jan 2026 Jackery and EcoFlow deals are examples of time‑limited opportunities. See our bargain‑hunter's toolkit for tracking deals.

What to avoid

Buying a unit because of a low headline Wh number without checking inverter continuous rating.
Assuming all panels are equal — panel wattage, orientation, and MPPT compatibility affect real solar throughput. For cold-chain or camp refrigeration, read our field notes on solar cold boxes and battery strategies.
Overlooking warranty exclusions for commercial or heavy cycling use.

“Price matters, but the right balance of usable capacity, inverter rating and recharge speed will save you time and money in the long run.”

Final takeaways — concise

Jackery HomePower 3600 — Best value for multi‑kWh home backup during current sale cycles; ideal when sustained runtime and surge capacity matter most.
EcoFlow DELTA 3 Max — Best value for portable, fast‑charging mid‑range power with strong solar charging options — great for RVers and frequent travelers during flash sales.
Buy tip: If the HomePower 3600 Plus falls under $1,300 in a bundle (as it did in Jan 2026), it becomes a compelling multi‑kWh value; if you need portability and fast recharge, the DELTA 3 Max at ~$749 is a strong pick.

Next steps — how to buy smarter today

Set an alert for the exact model you want. If you need both mobility and home backup, pair a stationary multi‑kWh unit with a DELTA‑class portable. Check warranty terms and confirm panel compatibility before checkout.
