Every station gets the same three checks against the devices you tick. Here's exactly how the answer is worked out, and where every number comes from.
How much energy you need
For each device, we multiply its watts by how many you have and the hours a day you use it, then add them up and multiply by the number of days before you can recharge.
How much energy a station really gives you
Some energy is lost turning the battery's power into household AC power. Anker publishes about 85% as the share that reaches plug-in devices, so we use that for every brand.
The three checks
- Enough stored energy. Usable Wh must cover the Wh you need.
- Enough output. The station's continuous watts must cover everything you ticked running at the same time.
- Enough surge. The station's surge rating must cover the extra jolt when the biggest motor starts, such as a fridge compressor or a pump.
A station that passes all three "Runs it". If it passes but would have less than 20% charge left at the end, it's "Just enough". The best match is the smallest station that runs everything comfortably and delivers to your state.
Why fridges are different
A fridge's compressor switches on and off through the day, so its running watts would overstate how much energy it uses. Instead we use the kWh per year printed on its yellow EnergyGuide label. 350 kWh a year is an example for a modern ENERGY STAR fridge; enter the number on your own label for an accurate answer.
Where the numbers come from
- Device watts: Jackery's appliance wattage chart (updated 28 Sep 2026) and Virginia Tech Extension. Where a source gives a range, we use the higher end, so the answer errs on the safe side.
- EV charging: the US EPA's figures for Level 1 charging: 1.9 kW, adding about 5 miles of range per hour.
- Inverter losses: Anker's published runtime formula.
- Station specs: capacity, output, surge and weight from each brand's own US product page, checked 1 November 2026.
Your devices may use more or less than these typical figures. If the label on your device shows a different number, type it into the tool.
Where each brand delivers
Delivery areas come from each brand's US shipping policy (EcoFlow, Jackery, Anker), checked 1 November 2026. All three US stores deliver to the 48 contiguous states, none delivers to Alaska or Hawaii, and Jackery doesn't accept P.O. box addresses. Policies change, so check at checkout.
What the tool isn't for
Will It Run? is for plug-in devices. Don't rely on it for medical equipment, and use a licensed electrician to connect anything to your home's wiring.
