The short answer: the Jackery HomePower 3000 runs anything that plugs into an ordinary 120V outlet and draws under 3,600W. That covers a fridge, router, lights, phones, a laptop, a TV, a CPAP, a microwave and a window air conditioner. It cannot run anything that needs 240V, such as a well pump, central air conditioning, an electric dryer or an electric range.
What matters for most appliances is not whether it starts but how many hours the battery lasts. This page gives that number for each one, so you can add up your own must-keep list.
How to read the hours
The battery holds 3,072Wh (watt-hours). To get hours for any appliance, divide the energy by its power draw in watts. Some energy is lost converting from battery to household power, so the table assumes about 2,700Wh is usable. That is a sensible planning number rather than a measurement from a lab, so treat every figure as approximate.
Draws are typical figures for ordinary household equipment. Your own appliances will differ, so look at the label on the back for the real wattage.
| Appliance | Typical draw | Hours from a full battery (running alone) |
|---|---|---|
| Wi-Fi router and modem | 10 to 15W | about 8 to 9 days |
| Phone charging | about 15Wh per full charge | about 180 charges |
| Ten LED bulbs | about 50W | about 54 hours |
| Laptop | 40 to 60W | about 45 to 65 hours |
| CPAP (without heated humidifier) | 30 to 50W | about 5 to 9 nights |
| Television | 80 to 120W | about 22 to 34 hours |
| Refrigerator or fridge-freezer | 1,000 to 1,500Wh a day | about 2 days |
| Gas or oil furnace blower | 400 to 600W | about 4.5 to 7 hours |
| Window air conditioner (small) | 400 to 600W | about 4.5 to 7 hours |
| Coffee maker | 800 to 1,000W | about 3 hours of brewing |
| Microwave | about 1,000W | about 2.5 hours of cooking |
| Sump pump (120V) | 800W while running | many hours, because it cycles |
| Portable space heater | 1,500W | under 2 hours |
The fridge row is the one to take most seriously. It runs all day and all night, so it sets how long the battery lasts. Our refrigerator runtime guide goes through why a fridge uses so much less than its nameplate suggests.
A realistic day: what the battery does when you combine things
Nobody runs one appliance. Here are three combinations, using the same planning number.
| Household | Loads | Energy per day | Days on a full battery |
|---|---|---|---|
| Bare essentials | Fridge, router, lights, phones | about 2,000Wh | about 1.3 days |
| Working from home | Essentials plus laptop and monitor for 8 hours | about 2,500Wh | about 1 day |
| Essentials plus CPAP | Bare essentials plus a CPAP overnight | about 2,400Wh | about 1.1 days |
These numbers do not count the solar panels that ship with the bundle. On a bright day, panels can return a good part of that daily total, which stretches a one-day battery into a longer outage when the weather cooperates. In a winter storm, they return much less. Our three-day outage guide shows the day-by-day battery maths for a clear spell and for three grey days.

What it runs well
These are the jobs the HomePower 3000 does comfortably, hour after hour.
- Fridge and freezer. Runs a normal fridge-freezer for about two days alone. A second chest freezer adds load; see our chest freezer guide.
- Internet, lights and phones. All three together use a small fraction of the battery each day. A router alone would last more than a week.
- Sleep apnoea machine. A CPAP uses a few hundred watt-hours a night, so the battery carries it for several nights. See the CPAP guide for the heated-humidifier caveat.
- Working from home. A laptop, a monitor and a router for a workday cost roughly 500 to 700Wh. Our work-from-home guide has the full list.
- A gas furnace blower. The blower draws 400 to 600W, so it runs for hours, though a long cold night uses a lot of battery. The furnace guide covers gas, oil and electric.
What it runs for a short time
High-draw appliances start without trouble, since 3,600W is a lot of headroom, but they empty the battery quickly. Use them in short bursts.
- Microwave. About 2.5 hours of cooking in total. Reheating a few meals a day costs very little.
- Coffee maker. A few pots of coffee a day is fine. A heated warming plate left on all morning is not.
- Window air conditioner. Roughly five to seven hours from a full charge, longer if the thermostat cycles. Our air conditioner guide explains the difference between a window unit and central air.
- Space heater. It starts, then empties the battery in under two hours. Electric resistance heat is the hardest load for any home battery, which is why our space heater guide suggests alternatives.
What it cannot run
The limit is not capacity. It is voltage. The HomePower 3000 has 120V outlets only and no 240V outlet, so these are off the list no matter how full the battery is.
- Well pump. Runs on 240V and needs a strong start surge. See the well pump guide.
- Central air conditioning. Draws 3,000 to 4,000W at 240V.
- Electric dryer, range, oven and water heater. All 240V. Our washer, dryer and stove guide has cheaper workarounds, such as an induction burner and a clothes rack.
- A whole house. The unit cannot be wired into your electrical panel. The HomePower 3600 Plus is the one built for that, and our whole-house guide explains what that involves.
If anything on your must-keep list is in this group, the unit to look at is the Solar Generator 5000 Plus, which has 5,040Wh, 7,200W and both 120V and 240V. Our comparison of the three Jackery home units works through the choice.
A quick way to check your own list
- Write down what must stay on, and find the wattage on each label.
- Add up the watts of everything that could run at the same moment. If that total is under 3,600W, the unit can start it.
- Estimate hours of use per day for each, multiply, and add the results to get watt-hours a day.
- Divide 2,700 by your daily total to get the days on a full battery.

Who the HomePower 3000 suits
It suits a household whose outages last a day or two and whose list is the fridge, internet, lights, phones and perhaps a CPAP or a window air conditioner. It does not suit a home that needs a furnace and a freezer through a multi-day storm, or anything on 240V. Our full review covers the unit in more detail, and the buying guide compares it with the alternatives from other makers.
