A Watt hour (Wh) represent the estimated amount of energy an electrical appliance consumes in one hour. An appliance usually has the wattage it uses written on a label. This label is often at the back or bottom of the appliance.
To work out the Wh take the watts (W) of the appliance and multiply this with the hours used on an average day.
Example - Portable Fridge
If you're on a day trip with a portable fridge that consumes 25 watts to operate, one of our Yeti 500X power stations will be able to keep it on for approximately 20 hours.
25W * 20 = 500
Portable Fridge (25W): 20 hours
Portable Fridge (25W): 40 hours
Portable Fridge (25W): 60 hours
Portable Fridge (25W): 120 hours
Portable Fridge (25W): 240 hours
* times are approximate.
