Portability: a portable generator is expected to be, well, portable. This is because it is will be mostly used for outdoor activities such as tailgating and camping which will require you to carry the unit around. Some of the features that improve portability that you should watch out for include lightweight, a handle, presence of wheels or rollers and so on.

Noise Level: another top feature of any portable generator is the noise level. Most portable generators are already designed to be quiet. Some units also feature eco modes that operate even more quietly. You can go for these types especially when silent operation is a major factor for you.

Power and Outlets: 2000-watt generators are the smallest size and offer the best price range of portable RV generators. Most of them would work for simple outdoor activities like tailgating or camping. You may need larger units with more power if you need to power more devices.

Similarly, you should consider the types of outlets that you need your unit to have. Usually, a small quiet portable generator will have some 120V AC outlets and some USB ports. Larger units, with up to 4000 watts power will give you a 240V outlet along with the standard 120V. some units also have outlets for connecting more than one generator in parallel for increased power.

Usage: Generally, the type of generator you go for will depend largely on what it will be used for. You may need a quiet RV generator for use in an RV, camping purposes, tailgating and so on. If you are a regular user then any reputable brand should work for you. However, if your need tends towards a more consistent or heavy-duty use, then you would do better with a unit built for commercial purposes.
