Jackery HomePower 3600 vs EcoFlow DELTA 3 Max: which power station should you bring on an RV or flight trip?

Beat surprise power bills and dead batteries: which portable power station actually makes sense to pack for an RV trip — or even try to bring on a flight?

If you’re a deals-first traveler you’ve seen the flash prices: the Jackery HomePower 3600 Plus dropping as low as $1,219 in mid‑January 2026 and the EcoFlow DELTA 3 Max popping up at $749 during recent sales. Numbers look tempting — but for travel shoppers the real questions are practical, not promotional: How much usable energy will I actually get per pound in my trailer? Can I legally bring this on a plane or a ferry? How fast will it recharge between campsites or during a long day of driving? And when I factor in sale price, what’s the true cost‑per‑watt for my trip?

Quick verdict (most readers want one right away)

• For road trips and extended boondocking in an RV: The Jackery HomePower 3600 gives higher total capacity at sale price and is often the better choice if you prioritize raw runtime and want to run a mid‑size fridge, small chest freezer, lights and charge devices for several days without plugging in.
• For short van trips, day camps and fast recharges between stops: The EcoFlow DELTA 3 Max is the better-value, lighter, faster-charging pick — especially if you rely on daytime solar or want quicker AC top-ups at campgrounds.
• For air travel: Neither is realistically airline‑portable. International and U.S. carrier rules limit lithium batteries; most power stations this size exceed allowed watt‑hour limits for carry‑on. Choose a compact sub‑160Wh travel battery if you must fly with power.

Why this comparison matters in 2026

Two trends accelerated through late‑2025 and into 2026 that directly affect your purchase decision:

1. Flash pricing plus bundling: Retailers ran deep discounts in early 2026 (example: Jackery HomePower 3600 Plus bundles, EcoFlow flash sales). That moves the cost‑per‑watt needle and changes which unit is the better deal for trips.
2. Operational expectations have risen: Travelers now expect near‑car charging speeds, solar integration and smart app control. Models that charge faster or accept larger solar inputs reduce downtime during road trips.

Side‑by‑side: practical travel factors

1) Capacity vs weight — what matters on the road

Raw watt‑hours (Wh) tell you how long a device will run, but the travel metric that matters is usable Wh per pound. That ratio dictates whether you lug the unit or pick something lighter and supplement with solar or an alternator charger.

• How to compute usable Wh per pound: usable Wh ÷ weight in pounds. Usable Wh = nominal Wh × usable depth of discharge (often ~90% for modern LFP; some manufacturers quote nominal capacity, not usable).
• Example (use these numbers as a template to plug real specs): If a 3,600Wh unit weighs 56 lbs and you can use 90% of capacity, usable Wh = 3,240Wh. Usable Wh per lb ≈ 57.9Wh/lb.
• What to aim for: 40–70 Wh/lb is typical for large portable stations. If your rig has weight limits or you backpack often, aim higher (lighter is better even if capacity is lower).

2) Airline and ferry rules — what you can actually bring

Short answer: don’t plan to fly with these large power stations. Airline and shipping rules around lithium batteries have not relaxed; they are generally more strictly enforced than in earlier years.

• Airlines (carry‑on rules): The industry standard continues to treat batteries by watt‑hour: under 100Wh allowed freely, 100–160Wh allowed with airline approval (limited spare batteries), and >160Wh typically prohibited in passenger aircraft. Most large portable power stations exceed 160Wh by a wide margin — they are not airline‑portable. Check your carrier; some cargo services will ship them with special handling, but that’s costly and can take days.
• Ferries and maritime transport: Rules vary. Many passenger ferries allow power stations if declared and stowed per operator guidance; Ro‑Ro and freight ferries treat them like dangerous goods and may require documentation. Always contact the operator in advance and carry manufacturer spec sheets and MSDS if you plan to board with a large battery.
• Tip: For mixed travel (fly+drive), purchase or rent a small sub‑160Wh travel battery for flights and buy or ship the large unit to your destination. In 2026, same‑day rental services in major outdoor hubs have become more common and can save headaches.

3) Charging speed — recharge time between camps

Charging speed is the practical limiter on how you use a power station while traveling. Two things matter: maximum AC input charging rate and maximum solar (PV) input.

• EcoFlow advantage: Across multiple DELTA generations EcoFlow has prioritized fast AC charging and multi‑stage input (sometimes branded tech names in their marketing). That means you can often go from near‑empty to 80% in roughly an hour on AC at full input rates on the DELTA family — a big advantage when you only have an hour at a service area or the campground office.
• Jackery trade‑offs: Jackery’s HomePower 3600 focuses on larger capacity and bundled solar options. AC recharge rates are solid but typically slower than EcoFlow’s fastest charge modes — translate that to longer downtime if you’re relying on shore power between boondocking days.
• Solar charging: Both brands support portable panels and MPPT charging. For travel use, always favor higher PV input limits (more watts in) and accept that real‑world solar harvest is ~50–70% of rated panel power, depending on conditions. A 500W panel will rarely deliver 500W continuous.

4) Output capacity and appliance compatibility

Check continuous AC output (watts) and surge capability for appliances with motors. RV fridges, coffee makers, portable induction cooktops and HVAC fans spike at start‑up — you’ll need a unit that can handle the surge.

• Continuous vs surge: A unit advertised as 3,000W continuous with a 6,000W surge is ideal for short motor starts. If you want to run a full RV AC, you’ll still be grid‑limited unless you combine battery with an inverter or generator.
• Practical tip: For overnight off‑grid with a mid‑size compressor fridge and lights, focus on Wh capacity. For daytime power at campsites where you sometimes need to run a microwave or hair dryer, output wattage matters more.

Cost‑per‑watt: how to compare sale prices (real buyer math)

Deals change the math. Use this simple formula to compare apples to apples:

cost‑per‑watt = sale price ÷ nominal Wh (then adjust for usable Wh if you want more precision)

Example calculations using January 2026 sale prices spotted in public deal trackers:

• Jackery HomePower 3600 Plus — sale price $1,219: If nominal capacity is 3,600Wh, cost‑per‑Wh = $1,219 ÷ 3,600Wh ≈ $0.34/Wh. Adjust for usable (90%) → $0.38/usable Wh.
• EcoFlow DELTA 3 Max — sale price $749: If nominal capacity is 2,016Wh (check the spec sheet for your exact model), cost‑per‑Wh = $749 ÷ 2,016Wh ≈ $0.37/Wh. Adjust for usable (90%) → $0.41/usable Wh.

What that tells you in practice: on sale, Jackery’s higher capacity can deliver better value per Wh — but the EcoFlow can beat you in convenience value because it charges faster and weighs less, so actual trip costs (paid campground power, time, towing fuel) can shift the real ROI.

Solar compatibility and set‑ups that work on the road

Both brands support portable panels and MPPT charging, but there are practical differences you can leverage:

• Panel bundle vs modular panels: Jackery often bundles a 500W panel option with the HomePower 3600 Plus, which is convenient if you want an out‑of‑the‑box solar kit. EcoFlow supports third‑party panels and sometimes offers higher PV input ceilings on their controllers — good for scaling up.
• Panel deployment: For real travel use, 1,000W of mounted or portable panels (split across morning and afternoon angles) is a practical target to maintain a ~2–3kWh station on multi‑day boondocks in sunny climates. Expect lower output on cloudy or winter days.
• Battery chemistry and longevity: Travel users should prefer LFP (LiFePO4) chemistry for cycle life if they plan to rely on the station year after year. Both brands have been increasing LFP adoption across 2024–2026; confirm your model’s cell chemistry when buying.

Real‑world travel scenarios (pick the scenario that matches your trip)

Scenario A — 5‑day boondocking in a quiet desert canyon (no hookups)

• Priority: Maximum runtime for fridge + lights + phone charging.
• Recommendation: Jackery HomePower 3600 plus a 500W panel bundle — the larger battery reduces risk on consecutive cloudy days. On sale prices, this is often the best cost‑per‑Wh option.
• Why: Higher total Wh means fewer days you need to run a generator or conserve power heavily.

Scenario B — Weekend van trip with short stops and 2–3 hours between shore power opportunities

• Priority: Fast top‑ups and lighter carry weight.
• Recommendation: EcoFlow DELTA 3 Max for faster AC recharge and better power density. If you only need to top up a couple of times, faster charging beats raw capacity.

Scenario C — Fly into a national park then road/van rental

• Priority: Minimize shipping hassle and follow airline rules.
• Recommendation: Rent or ship the large station to your destination; fly with a compact sub‑160Wh travel battery in carry‑on. In 2026 many outdoor rental services now offer same‑region delivery for power stations — check local rental platforms like the ones that support portable pitch‑side and creator kits.

Durability, warranty and trust — important for affiliate buyers

Deals are great, but for travel buyers you should prioritize warranty length, cycle rating and customer support responsiveness. Both Jackery and EcoFlow expanded warranty and in‑field support programs in 2024–2026; still verify whether your seller is an authorized reseller to preserve warranty coverage. If you’re comfortable with refurbished or open‑box gear, reputable refurb options can save serious money — similar guidance applies when buying refurbished electronics for travel use.

Actionable checklist before you buy (use this at checkout)

1. Confirm the nominal Wh and usable Wh on the manufacturer spec sheet.
2. Divide sale price by nominal Wh to compute baseline cost‑per‑Wh. Adjust by assumed usable % if needed.
3. Check the continuous AC output and surge capability against the appliances you plan to run.
4. Verify solar input (max W) and connector type — does it suit the panels you already own? Will you need additional adapters?
5. Confirm weight and compute Wh per lb. If you’re packing it into a vehicle with payload limits, test weigh the unit or ask for exact kg/lb specs.
6. Contact your ferry or airline carrier in advance if you plan to move the unit by water or air. Keep MSDS and spec sheets handy.
7. Buy from an authorized seller and check the warranty terms — especially for travel use where drop damage and temperature extremes are common.

2026 buying and price‑drop strategies for deal shoppers

As buyers chasing the best price, you should:

• Track flash sales and weekday drops: Many big discounts hit mid‑January and again in spring 2026. Use price‑tracking tools or set alerts on affiliate pages.
• Bundle smartly: Sometimes a small increment in cost to get the bundled solar panel or extra inverter is better value than buying panels separately.
• Consider refurbished or open‑box units: For road travelers who don’t need mint packaging, reputable refurb units can cut cost‑per‑Wh dramatically — but confirm battery cycle life and warranty. If you’re running a small field production setup, field-tested kits and portable network & COMM kits are another place to look for used and modular gear.

Final takeaways — which to buy for your travel style

1. If you prioritize raw off‑grid runtime and the best cost‑per‑Wh during sales: lean toward the Jackery HomePower 3600 (especially when it appears in bundle deals).
2. If you prioritize lighter weight, faster top‑ups and flexibility between shore power stops: the EcoFlow DELTA 3 Max wins for weekenders and travelers who value quick turnaround.
3. If you plan to fly: don’t expect either to go into checked luggage or carry‑on — choose a travel battery under 160Wh or arrange ground shipping.

Closing — how I’d choose for my next trip (practical example)

If I were planning an 8‑day mixed car/boondock trip in 2026 with an intermittent generator and a 500W roof panel on my camper, I’d buy the Jackery HomePower 3600 on a sale because it reduces generator runtime and buys me quiet evenings. For a 3‑day van weekend where I want to move quickly and top up between coffee stops, I’d pick the EcoFlow DELTA 3 Max for its faster recharge and lower weight. In both cases I’d set a price alert today — early 2026 deals have shown the biggest swings and you can save hundreds if you time a purchase right.
