This product is best for portable charging like in the car or anywhere the standard 120V charger will not work. Portable inverters are not recommended with the 120V charger as it will most likely destroy your batteries. While a little slow, it works well. A drawback- it requires more than just battery power, the engine must run, so charge while driving!
