Beat the blackout panic: real-world Jackery HomePower 3600 Plus runtimes (and what they cost when you’re on a budget)

If you’re tired of hunting discount deals only to discover a power station won’t keep your freezer, fridge, or CPAP running, this hands‑on guide is for you. We break down realistic runtimes for common home gear, show the math behind a backup-power calculator you can use right now, and convert the current sale price into a useful cost-per-hour so you can decide whether the Jackery HomePower 3600 Plus makes sense for your emergency plan.

Deal note (Jan 15, 2026): Jackery HomePower 3600 Plus is at an exclusive low of $1,219, or $1,689 bundled with a 500W solar panel. Use those sale prices below to see real cost-per-hour numbers.

Quick bottom line (most important takeaways)

Nominal battery size: ~3,600 Wh (3.6 kWh). After inverter losses and a practical depth-of-discharge, expect ~2.7–3.1 kWh usable for calculations—this article uses a conservative ~2,850 Wh usable.
Single full-discharge cost-per-kWh: at $1,219 you’re effectively paying roughly $428 per usable kWh; the solar bundle raises the upfront cost but lets you recharge off-grid.
Real runtimes: Router + Wi‑Fi lasts days, a modern fridge runs ~19 hours (conservative), a CPAP can last ~12 nights, and a microwave has ~170 minutes of total cook time on a full charge.
Best ROI trick: think in lifecycle terms (cycles/years). If you use this station for monthly full discharges over 5 years, the per‑hour cost for critical loads falls into the $0.50–$3/hr range — far more reasonable for emergency planning.

Why the sale price matters in 2026 (and what’s changed recently)

By late 2025 and into 2026, portable power stations saw two big shifts: prices continued to fall modestly after the post-pandemic battery-cost squeeze, and consumer expectations rose because more people now treat these units as true emergency infrastructure — not just camping toys. Manufacturers pushed larger capacities, better LiFePO4 chemistries, and improved inverter efficiency. Flash sales (like the one that put the HomePower 3600 Plus at $1,219) are now common entry points for buyers seeking household resiliency without breaking the bank.

That said, even at sale prices, a portable station is an investment. Converting that sticker price into tangible runtime and cost-per-hour helps you decide if this model fits your household priorities (fridge vs. lights vs. medical devices vs. EV charging) — which is exactly what we do next.

How we calculate runtime (the simple backup-power calculator)

Use this three-step method whenever you want a fast estimate.

Estimate usable energy: Nominal battery Wh × inverter efficiency × recommended max depth of discharge. For conservative planning use ~0.75–0.80 of nominal. Here we use 2,850 Wh usable (3,600 Wh × ~0.79).
Sum continuous load: Add the wattage of devices you’ll run simultaneously. For appliances that cycle (fridges) use an average running wattage, not the peak compressor draw.
Runtime (hours) = usable Wh ÷ total watts. For intermittent devices (pumps/microwaves), calculate total minutes of operation = (usable Wh ÷ device W) × 60.

Why we use a conservative usable Wh

Inverter losses, cable losses, and the recommendation to avoid cycling a battery completely mean you’ll get less than the nominal Wh printed on the spec sheet. LiFePO4 improvements in 2025–26 help, but for emergency planning it’s safer to use a conservative usable figure so you’re not surprised when the lights go out.

Practical runtime estimates (real-world house gear)

Below are common loads, a realistic average wattage, runtime on a conservative 2,850 Wh usable capacity, how long that would sustain normal daily service, and the single-discharge cost-per-hour using the sale price of $1,219. We also include an amortized per-hour example assuming 60 full cycles (monthly full discharge over 5 years) to show long-term value.

Wi‑Fi router + modem (20 W)

Runtime: 2,850 ÷ 20 ≈ 142.5 hours (~6 days). Single-discharge cost/hour: 1,219 ÷ 142.5 ≈ $8.55/hr. Amortized over 60 cycles: total hours 8,550 → cost/hr ≈ $0.14/hr.
Six LED lights (54 W total; 9 W bulbs)

Runtime: 2,850 ÷ 54 ≈ 52.8 hours (~2.2 days). Single-discharge cost/hr: ≈ $23.10/hr. Amortized (60 cycles): ≈ $0.39/hr.
Modern refrigerator (150 W average cycling)

Runtime: 2,850 ÷ 150 = 19 hours. Single-discharge cost/hr: 1,219 ÷ 19 ≈ $64.16/hr. Amortized (60 cycles / 5 yrs): ≈ $1.07/hr. Tip: pre-cooling and keeping doors closed stretch that time.
Chest freezer (100 W average)

Runtime: 2,850 ÷ 100 = 28.5 hours. Single-discharge cost/hr: ≈ $42.77/hr. Amortized: ≈ $0.71/hr.
CPAP (30 W)

Runtime: 2,850 ÷ 30 = 95 hours (that’s ~12 nights of 8‑hour use). Single-discharge cost/hr: 1,219 ÷ 95 ≈ $12.83/hr. Amortized: ≈ $0.21/hr. For medical devices, prioritize a dedicated circuit and confirm inverter pure-sine output and DC coupling if required.
Sump pump (800 W running, but intermittent)

Running continuously: 2,850 ÷ 800 ≈ 3.56 hours of continuous motor time. But pumps are intermittent – if your pump runs 10 minutes every hour (typical in heavy rain), average energy per hour ≈ 133 Wh. That gives 2,850 ÷ 133 ≈ 21.4 pump‑on hours, which equates to ~5.4 days of frequent 10‑min/hr operation. Single-discharge cost/hour while pump is active: 1,219 ÷ 21.4 ≈ $56.89/hr.
Microwave (1,000 W) — short bursts

Total minutes of cooking on one full charge: (2,850 ÷ 1,000) × 60 ≈ 171 minutes total. In practice, that’s many short meals (e.g., ten 1.5‑minute uses), but avoid heavy continuous loads during a critical outage.
