It is better to have several outlets on your portable generator. There are two main reasons to have several outlets on a portable generator.

The first reason is to spread the load. The load is the number of appliances connected to the generator. Spreading these connections over several outlets makes it easier for the generator to keep the power stable.

On the other hand, it is not recommended to use all outlets at the same time. Using all generator outlets simultaneously makes the generator work very hard. For a prolonged time period this can cause it to overload, or be overworked. An overloaded generator damages all connected devices, including the generator itself.

The second reason why having several outlets on a generator is useful is for the variety of outlet type. Most portable generators are fitted with two standard outlets; a 120 volt 20 amp plug and a 120/240 volt 30 amp plug.

Pay close attention to the amps and volts needed for the connected devices. Don’t connect devices that go over the mentioned volts and amps. If the generator is not fitted with an automatic circuit breaker, get one. This protects both your connected sensitive devices and the generators.

Portable generators that are designed to have a stable enough power for sensitive electric devices also have an additional plug type. Some lightweight hand carried portable generators even have a USB port.
