If your have variation of voltage from the utility (100-240), this product works as designed. I am a photovoltaic technician and use it to keep battery toped of & if a battery is lying around--it will prevent it from getting sulfated. I reached out to a name brand & I was disappointed that the rep (owner/ceo), didn't even know that his competitors have the voltage variation available like this offers. It prevents it from killing the power supply (charger) if you have constant voltage sages. I waited some time before evaluating it. It charges up to 14.4 vdc (for agm & gel batteries) & back to 13.6 vdc after the battery is charged (floating)--as it should. Have been using it for various weeks consecutively w/o a hickup.
Update: I purchased a 2nd unit to maintain my 2nd car's battery & the other unit has been reliable. I recommend this unit. Works as designed, a very good price, I have had the original one connected weeks straight day-after-day. Worthy buy.
Update #2: have been using this unit for months straight in a row DURING HEAVY voltage sages & outages AND OVERVOLTAGE situations (scarry situations) and to my surprise--still ticking as expected (better than). I have two other chargers doing maintenance for car batteries and I now have to purchase a replacement units (plural) for that usage. The only reason I don't purchase 1 or 2 more of this unit is because I need a higher capacity. I am going to look into seeing if this manufacturer has a higher capacity... i do like to give credit for a good quality item for a fair price. Good purchase
