I purchased this for trickle charging the battery on my tractor. It tends to sit (covered) in a sunny spot, and, it is an electricity hog when I use the lights on it. It has worked well for about a month maintaining the charge on the battery, making up for the poor output of the old generator on the tractor, and boosting the starting and lighting power.

This unit provides a constance 0.15 amp charge. I have a few concerns. I hooked up a high quality voltmeter to it and the charge read somewhere between 16 volts and 18 volts (off the scale on my volt meter). Under a load (once connected to the battery) it may read a lower voltage but I have not measured it under load.

My other concern is that this does not have any kind of voltage regulator. When your battery reaches its full charge there is a possibility of overcharging the battery.

In any event, it charges a battery over a period of about four days and keeps it charged.

A real plus to this unit is that it is accompanied by an excellent array of leads. It has an extension cord that is about 8 feet long. There are four types of leads enclosed with the package.

The first are bare wires (+ and - (red & black)) that, on the other end, plug into the unit or the extension cord.

The second are a set of alligator clips (+ and - (red & black)) that, on the other end, plug into the unit or the extension cord.

The third is a male cigar lighter adapter that plugs into the unit or the extension cord.

The fourth is a female cigar lighter adapter that plugs into the unit or the extension cord.

All of the connections and leads are of good to high quality.

With these attachments, you have the versatility you need to hook it up to any vehicle or 12v battery.

This is well worth the $50 (approximate cost plus shipping).

sometimes I leave my radar detector plugged in by mistake.
In my truck, it prevents the battery from going down. Doesn't
work or fit well in cars that don't have a flat area on the dash.

Product is made of cheap plastic that will crack after being in the sun for one season. The button that checks if the charger is working stopped functioning after a year.
