At last a battery maintainer is available that is both USB powered and simple to operate. The Battery Saver by Mr. Charge operates by inserting the battery maintainer into the vehicle’s cigarette lighter at one end and by connecting the other into the included USB power source. Nothing could be easier and keep your vehicle from a dead battery while it sits idle. Let the Battery Saver by Mr. Charge save your vehicle battery from a slow, draining end!
Ease of Use
The Battery Saver offers a clean, ultra-simple alternative to the dirty, under-the-hood trickle charger choices already available. The Battery Saver by Mr. Charge maintains your vehicle battery from a USB power source (included) by simply inserting the cigarette lighter adapter into your always-on vehicle receptacle. There is no possibility for reverse wiring since there are no clamps or loose wires to figure out. The engineered adapter utilizes an LED indicator to provide you all the information you need to ensure your vehicle’s battery is being taken care of.
The Battery Saver has been engineered in the USA by a team dedicated to getting the details right. It has been designed to provide the correct maintenance voltage for a wide range of battery operating conditions. The compensation is continuously variable unlike other chargers that “step” output levels guaranteeing they are always incorrect. The Battery Saver is also self-limiting to avoid damage when faulty batteries are attached or the battery requires charging.
