What Size Power Inverter Do I Need?
The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load).
Note:
1.This is a modified sine wave inverter,NOT applicable for devices which work by built‑in motor, hair dryers,air conditioners, coffee machine,water pump, induction cooker,refrigerators and microwave ovens etc.Make sure that the total rated power of the connected devices is ≤ 400W
2.Tighten the Positive (+) and Negative (‑) terminals when the car converter is in use
3.If the converter is directly connected with the cigarette lighter. The highest out put power must be under 150W. If higher than 150W,we strongly recommend you using the Clips to a battery ,because car cigarette lighter might not afford power over 150W.
4.The car converter suitable for DC12V and Car ONLY, not applied for DC 24V and airplane
5.Please do not leave the inverter in the ON position before car start.It's easy to damage the inverter before connected to the battery.The correct operation is connect to the battery first and then turn on the inverter switch
6. It's normal for the inverter to become warm while you are using it.
