While we love all of the smart features of the NOCO above, it all adds up to a rather expensive machine, so if you want something a bit more modest, this unit from Schumacher is a better way to go.
When talking about performance, this device is capable of charging most twelve-volt batteries in a few hours.
It has a fast setting that uses ten amps to fill the battery and a trickle setting that uses two.
The latter is important for when the battery is full, as this model has an automatic shutoff sensor that activates when that happens.
This way, you never have to worry about overcharging and damaging the battery.

In addition to a quick-charge mode, this device also has a jump mode that can start most nearly dead or all dead batteries, although it may not work all of the time.
This feature only uses fifty amps, so it might not provide enough juice for some all-dead versions.
What we like about this charger is that it is small and compact and super easy to use. It has solid-state switches that enable you to move back and forth between amperage quickly and easily without accidentally putting it on something you don’t want. It’s also only ten pounds, which makes it much easier to carry.
Overall, if you want something in your car for emergencies, this is an excellent choice.
