The Jackery HomePower 3600 Plus has been in my house since the start of hurricane season. Jackery sent it, this is a paid partnership, and what follows is what I found after a season with it in the house.
I expected a big battery in a nice box. What I found is a battery priced better per watt-hour than anything else I have looked at in this chemistry. It also has a ten-millisecond switch that turns it into a whole-house UPS for the things that matter.
The video goes through all of it on camera. This is the written version, with the numbers, the math, and the setup.
THE MATH THAT SOLD ME
Watts are what a box can push right now. Watt-hours are how much energy is in it, and that is what you pay for. This box holds 3,584 watt-hours.
Divide the price of the unit by 3,584 and you get about 53 cents per watt-hour. That is the number I care about, and it is the reason this review exists.
What that money buys is lithium iron phosphate, LiFePO4, the safest and longest-lived lithium chemistry you can put in a house. Jackery rates it at 6,000 cycles with 70 percent of capacity left at the end. Cycle it every day and that is over sixteen years. Cycle it for storms and cold snaps and your kids will inherit it.
Under 55 cents a watt-hour for that chemistry and that cycle count is the best I have found. That is the whole reason this box is in my house.
Most people buy these on the watt number printed on the front and never do this division. That is how you overpay.
WHAT 3,600 WATTS ACTUALLY RUNS
The unit puts out 3,600 watts continuous and 7,200 watts surge. Surge is the number that matters for a fridge, a pump or anything with a motor, because motors spike when they start.
The test I ran on camera is the simplest one. Plug a 1,500 watt space heater into one of the AC outlets and switch it on. The watt number on the display jumps to about 1,500 and the box does not blink.
That is one heater. A fridge pulls a fraction of that. Jackery’s chart says two to three days on a 100 watt fridge, and the label inside your own fridge door gives you the number you plan around.
A microwave, a coffee maker or a hair dryer pulls 1,000 to 1,500 watts and any one of them runs without a thought. Run the fridge, the router, the lights and the phones together and you are still using a fraction of what it can push.
The front panel carries five AC outlets, four standard 20 amp household outlets and one 30 amp TT-30, the RV plug. Two USB-C at 100 watts and two USB-A at 18 watts sit beside them.
One unit is 120 volts. When you want 240 for a big well pump or a dryer, a second unit ties in on the expansion port and you have it. Start with one and grow.
THE BATTERY
Lithium iron phosphate does not behave like the battery in your phone. It does not swell, it is far more stable under heat than the older lithium chemistries, and it does not mind sitting at full charge for months.
Jackery rates it at 6,000 cycles to 70 percent and a 16-year battery lifespan. That is a house appliance, not a gadget.
It also holds its charge on the shelf. Jackery calls it ZeroDrain. In plain terms, the box you topped off in June is still ready in October, which is exactly what you want from a hurricane battery.
It is rated to run down to 14 degrees Fahrenheit and to charge at freezing or above. In Ormond Beach that never comes up. In North Idaho it lives inside where it is warm, which is where the outlets and the fridge are anyway.

CHARGING IT BACK UP
Four ways in. A wall outlet, solar, a gas generator, or wall plus solar at the same time.
From the wall, two and a half hours at 1,800 watts. Wall plus solar together, two hours. That is the length of a movie for a full 3,584 watt-hours.
Jackery sent two SolarSaga 200 watt panels with the unit. I set them up in the yard on camera. Unfold them, point them at the sun, plug into the DC input, and the input number on the screen comes up. With a thousand watts of panel it fills in about four hours. With these two, plan on a sunny day from empty to full, which is free power in an outage that runs past a day.
The input I like for a long outage is the gas generator. Run a small generator for two and a half hours, fill the box, and shut the generator off. You get quiet, no fumes, and no fuel burned overnight while the fridge coasts on the battery.
That last one changes how much gas you need to store. Two and a half hours of generator time a day is a fraction of running one around the clock.
THE TEN-MILLISECOND SWITCH AND THE APP
Plug the box into the wall. Plug your gear into the box. When the grid drops, it switches to battery in under ten milliseconds. Jackery calls it UPS mode.
On camera I pulled the wall plug with a lamp and the router on the box. The lamp did not flicker and the display did not change. A computer, a modem or a CPAP never knows the grid went away.
The app shows the percent, the watts going in, the watts going out, and the hours left at the current draw. The hours figure is the useful one, because it tells you when to start rationing.
The app can also schedule charging for off-peak hours and run the house off the battery in the evening when rates are high. That is money back on the bill every month the power stays on.
BUILD, WHEELS AND PORTS
It weighs about 77 pounds, which is what 3,584 watt-hours of real battery weighs. Jackery put two wheels on the back and a handle that pulls up like a suitcase. You tip it and roll it.
Across a garage floor, up a ramp or over a threshold it rolls with one person, no problem.
The front panel carries the power button, the screen, two USB-C, two USB-A, four household outlets, the 30 amp RV outlet and the AC power button. The back panel carries the AC input, the DC input for solar, a reset button and the two expansion ports.
The AC expansion port ties in a second unit for 240 volts. The DC expansion port takes the add-on batteries, up to about 21 kilowatt-hours in total.
It measures 15 by 12 by 19 inches. It stands under a desk or in a closet and does not look like a job site.
HOW TO SET IT UP FOR A FAMILY
Pick the wall it lives on. Near the fridge, near the router, near an outlet. Plug it into the wall and leave it plugged in, so it sits full and the UPS mode is armed.
Run one heavy extension cord from the box to the fridge and leave it there. When the power drops the fridge never knows. Route the cord along the wall so nobody trips on it.
Put the solar panels, the cable and a printed one-page sheet of what plugs into what in a bag next to the box. Your spouse and your teenager need to be able to run this without you.
Charge from empty is about two and a half hours, so there is no excuse for it sitting at 40 percent when the storm comes. Top it off the day the watch is issued.
Then pull the main breaker for an hour on a Saturday and see what you missed. That hour is worth more than any spec sheet.

THE LIMITATIONS
A few things to know before you buy, so you buy the right setup the first time.
One unit is 120 volts. It covers the fridge, the lights, the router, the medical gear and the kitchen counter. A 240 volt well pump or a dryer means two units on the expansion port.
It is rated to run down to 14 degrees Fahrenheit. If you live where winter goes below that, give it a spot inside, which is where the outlets and the fridge are anyway.
Solar speed depends on panel wattage. A thousand watts of panel fills it in about four hours. Two 200 watt panels take a sunny day, so buy the panels to match how fast you want it back.
It is quiet. Under a light load you will not hear it. Under a heavy load the fans come up to about the level of a dishwasher, with no fumes, so it runs inside next to the fridge.
And 77 pounds rolls. Pick the room it lives in and leave it there. None of this is a strike against it. It is how you size the purchase right.
VERDICT
The warranty is three years, plus two more free when you buy direct from Jackery, five years in total.
Three things it does best. The price per watt-hour on lithium iron phosphate rated for 6,000 cycles. The ten-millisecond switch, which makes it a whole-house UPS for the things that matter. Four ways to charge it, including off a gas generator in a long outage.
The one thing to plan for is 240 volts, which takes two units.
It is for a family that wants the fridge, the lights, the router and the medical gear covered for the first days of an outage. No gas cans in the garage. It belongs on the wall next to the fridge, plugged in, full, and forgotten until the lights go out.
