What Will the RV Battery Run?
Your RV’s battery is a crucial component, powering everything from the lights and appliances to the water pump and entertainment system. That said, one question that frequently arises from RV owners is, “what will the RV battery run?”. Let’s explore everything you need to know about what your RV battery will run, and why it’s essential to manage your power supply when living off the grid.
If you’re planning on taking your RV off the grid, you need to be careful about the appliances you use. Your RV battery only has a limited amount of capacity, so using appliances that draw too much power can quickly drain the battery and leave you powerless. When it comes to appliances, the biggest culprits are usually anything that generates heat, such as ovens, stoves, and even hair dryers. Small appliances like televisions, phone chargers, and laptops typically have a lower draw, making them more suitable for use off the grid.
