The Jupiter 2000-Watt Inverter Cost


If we landed on a current web page at Harbor Freight, then this device is selling for roughly $169 and if you think that is expensive, the company issued a coupon that expired in March 2023 cutting $30 off the price.

Right now, at least one vendor on the Amazon marketplace is selling this model for $200. It is doubtful that you will find this device on sale anywhere else unless they are a Harbor Freight dealer.

In any search, the options for this device have been limited to either Amazon or the Harbor Freight website. You may have to wait till the company issues another coupon before getting this inverter at a reasonable cost.

Our Harbor Freight Jupiter 2000-Watt Inverter Review


One of the biggest red flags you can run into is when no one is talking about this device and only Harbor Freight has information on it. This is something we do not like as we cannot get a well-rounded view of the machine and how it works.

From the specs and descriptions issued, this device looks to be a good item to invest in. However, its size and its inconsistent performance may have you looking elsewhere for a better inverter.

Another red flag will be that this device is not mentioned on any top best lists comparing different inverter models and their brands. While this lack does not make this a bad machine, it does make you wonder about it.

With its peak wattage at 4,000 watts, it should be a good device that protects your electrical system from surges. Plus, the 2000 continuous running watts allow you to run several devices at the same time.

Just be careful not to create a large demand and watch which devices you plug into this inverter. With 2 GFCI outlets built-in, your electrical system should have plenty of protection when those surges take place.

The best we can say is that it is made for and sold by Harbor Freight and you may get a good machine or not.

What do Other Jupiter 2000-Watt Inverter Reviews Say?


The reviews are few and far in between. We came across only 1 independent review for print websites and it gave a glowing review of this device. The reviewer stated that this was a better machine than the Renogy 2000 even though the latter was cheaper.

Most reviews were online and like the Amazon reviews, they were mixed. Many owners did not have a great experience and were very negative in their comments about this device. One owner simply said the device just gave out.

Only 73% of verified owners gave this device 4 to 5 stars which is not very good. With 27% giving it 3 stars or less, it tells you that you are taking a bit of a gamble purchasing this inverter.

One owner liked the device and said it ran all of his electrical devices except for the microwave. No matter what he did, it would not run his microwave. Another owner said it would run smaller electrical devices but not his hot plate.

Finally, the owners that gave this device 5 stars claimed it worked as advertised, including running their microwaves. It is a hit or miss device.

Some Additional Words

The hit and miss reputation for Harbor Freight items seems to cover tools, electrical devices, and other pieces of equipment they sell. The company offers these devices and tools at a great price and even throws in some coupons to further help your budget.

However, not all their inverters and tools work the same for every customer. As you can see by the customer reviews, it is a hit or miss type of purchase. You may be lucky when you buy yours or you may have to return it and try again.
