Peak are the manufacturer of the next product to make our list. It has been designed to provide maximum power, at least for its size, whilst also being extremely easy and safe to use.
The device is designed for direct connection to the vehicle battery. To this end it does come with a useful mounting bracket (very handy!) but it is going to be a little more time to set up than a plug and play option as we saw above. This RV power inverter is ETL certified for a device that is extremely safe in operation.
