All RV charging systems are not created equal, and that can spell disaster for your RV electrical system if you're not careful. RV electrical power can be notoriously unstable, so you should choose RV charging systems that offer features such as input voltage monitoring, to help make sure voltage spikes don't harm your converter or your costly electrical appliances.
You should also look for RV charging systems that power up rapidly and can handle all of your RV electrical needs. Choose a converter that will automatically adjust for power spikes and surges and will shut down if the charger overheats. If you don't choose RV charging systems with these features, you can blow out appliances and entire electrical systems due to fluctuating currents. Choose a reputable and warranted RV charging system to make sure this does not happen to you!
