a lamp, a mobile phone charger? We need to obtain a silent generator to take on promotional visits. We need to run a credit card machine, mobile phone charger, display (one lamp) and possible a lamp
The quietest generator I've worked with is a Honda. From what you state you need at least a 10 amp output at 120 volts, so that is about 1500 watts. Honda does have a few in the range you need, maybe the 2200watt would be a good choice and not too expensive. Operate them only outdoors, never inside.
