Your unit should be in its original condition with the included chargers and must be packaged inside an outer unmarked shipping box. Please remove ALL of the original labels/stickers on the outside of the box before printing/attaching the return label then drop it off at any FedEx location. If you do not have the original shipping box, any generic box will work just as well.
EENOUR is not liable if your package is damaged or lost due to mislabeling or improper packaging before it is dropped off at the FedEx facility.

Using the power consumption of an Car Refrigerator, you can calculate the electricity cost per hour of use. Here is the formula.
electric bill:
= Power consumption per hour (kW) x Hours of use (hours) x Unit price per kWh (USD/kWh)
= Power consumption per hour (W) ÷ 1000 x Hours of use (hours) x Unit price per kWh (USD/kWh)
* Since the power consumption per hour written on electrical appliances is displayed in W, when converting W to kW, power consumption (W) ÷ 1000
For example, an Car Refrigerator with 50W power consumption
The theoretical electricity cost per hour is:
50 (W) ÷ 1,000 x 1 hour (usage time) x 27 USD (electricity rate unit price) = 1.35 USD
After 1 day of continuous use:
1.35 USD x 24 hours = 32.4 USD
*1 kW = 1,000 W, so divide by 1,000.
* Calculations are based on an electricity rate unit price of $27.00/kWh (rounded down to the third decimal place).
