They are very happy because they are able to charge their phones from the car battery electricity. As per some users, the Stanley 500W inverter is even cheaper than buying from an offline store. They say that it is a good value for the money because it does the job.

Of course, it is a very handy tool because it is easy to use compact size power inverter.

The Stanley 500W car inverter has both pros and cons. It has many pros like compact size, good price, nice look and it is a great unit for the camping use. On the down side, the 12V power inverter has many negatives. First of all the cable connectors are low-quality connectors they fit loosely. More importantly, the power inverter failed to give the rated 500W output. It is good for a small amount of power consumption; many users have complained that it failed to give the output power as claimed by the product creator. Additionally, many users complained that it is a cheaply made product. However, it is a low-price product so you can’t expect much from this unit.

A slim design power converter from Stanley that does the work.

Conclusion – STANLEY PI500S Inverter Review

At the end, I will say that it is not a very good car power inverter. There are many reasons such as it is made of a low quality plastic material so it is not very durable. Additionally, the 500w Stanley power converter failed to give the rated 500-watt output electricity. The Stanley inverter has created many unhappy users because majority of the users are not happy with the unit. Of course, it is a lightweight and beautiful inverter that sells at a low price but it fails to work for the main purpose it is made for. Therefore, I will not recommend buying this product. If you want to buy it, please research more on this before you take the final decision.
