Great for an emergency

Although I only bought the generator a couple of months ago and have tested it once every month it seems to be fine . I haven't had an opportunity to use it yet for an emergency.

Quiet and Easy to use

[This review was collected as part of a promotion.] This GP5500 Single Fuel generator is amazing! It's not too noisy and it's very easy to move. It seems very well built and very durable. It powered up our refrigerators with no issues!

It came with a battery

[This review was collected as part of a promotion.] It's quieter than most generators you can use 120 to 240 vote. It's got different plugs and super heavy but once you get it together, you can move it just about through anything.

Perfect little bit powerful generator

[This review was collected as part of a promotion.] Such a great and reliable/ durable generator. This one powers our refrigerator and is so handy to have during hurricane season giving us peace of mind in case we loose power.

Dependable!

[This review was collected as part of a promotion.] This is hands down one of the most dependable brands of generators on the market! It can power multiple appliances at once! This saves you in the midst of hurricane season in Texas and is a staple!

Easy setup and efficient usage

[This review was collected as part of a promotion.] Worked well after a short setup. It is very nice being able to switch between gas and propane. Was able to keep our camper powered all day with our propane tank.
