Tesla’s Powerwall home battery is already a hit, and the device could prove to be quite useful in a variety of instances, including keeping the lights on during a power outage or feeding back energy to the grid. But how how much power can Tesla’s new Powerwall battery store, and how can you quantify it in the context of the devices in your home?

That’s one question Popular Mechanics set out to answer, with help of GE data, for the 10kWh Tesla Powerwall battery. The site went even further, telling us how many hours of TV you’d be able to watch on a full Powerwall, how long you’d be able to keep your Wi-Fi going, or how many margaritas you could blend.

Here’s how long the Powerwall will last, if you were to only do one of the following things:

  • charge your iPhone 952 times (you can charge a flip phone 2,000 times)
  • run your laptop for 200 hours
  • blend 4,000 margaritas
  • run 30 loads of laundry (without drying)
  • dry 4 loads of laundry (assuming you washed them by hand)
  • brew 30 pots of coffee
  • run a window air conditioner for 10 hours
  • run a space heater for more than 6.5 hours
  • keep an electric furnace on for half an hour
  • run an old tube-style TV for 130 hours, an LCD for 50, or a plasma for 30
  • microwave 300 Hot Pockets
  • keep your fridge on for 50 hours
  • keep your Wi-Fi going for 60 days
  • make 360 pieces of toast in a toaster (or 1,000 in a toaster oven)
  • power one 60-watt incandescent lightbulb for 170 hours or a CFL 60-watt equivalent for 560 hours

During a power outage, when you’re using the devices in your house as you would normally, the site says Tesla’s Powerwall would last for about eight hours.
