I do not think so. Be careful with inverters of this type. They are called "modified sine wave inverters"
And what you really need is termed a "True Sine Wave Inverter." A modified sine wave inverter delivers a digital wave form that over time will destroy your laptop. It also is very probable that it is what is causing your problems. A "True Sine Wave Inverter" produces a real waveform and also switches at 60HZ. It gives the same purity of,power as your electric company does. However these are more expensive then the modified sine wave models are. Most of those come with warnings not to use any devices that need chargers.. Examples of true sine wave inverters are made by Samlex, Xantrex, ( my two favorite producers ) and a few other companies. see less

Answer:
Look on the coffeemaker or supplied literature and find out how many watts it uses. AMPS times VOLTS equals WATTS. For example, my 4 cup Mr. Coffeemaker uses 650 watts at 120 volts, it needs 5.4 amps HOUSEHOLD CURRENT (650 divided by 120). Trying to power this coffeemaker from a 12 volt battery, you need 54 amps … see more Look on the coffeemaker or supplied literature and find out how many watts it uses. AMPS times VOLTS equals WATTS.
