You'll want to consider the type of shore power adapter you need, which depends on the type of boat you have. There are three main types: 30-amp, 50-amp, and 100-amp.
The size of your boat and the number of appliances you plan to use will determine which type of adapter you need. A 30-amp adapter is suitable for smaller boats with fewer appliances, while a 50-amp or 100-amp adapter is needed for larger boats with more appliances.
Look for an adapter with a high surge protection rating to prevent damage to your boat's electrical system. A higher rating means better protection.
When shopping for a shore power adapter, be sure to check the voltage and amperage rating to ensure it matches your boat's electrical system.
