Plug-in starter and charger
Most trickle current chargers can provide 2 to 10 amps, many of which have multiple settings. This is due to the fact that, in general, it is better for battery life to provide some (or all) power at a slower rate through a lower amperage, but waiting for a 2 amp trickle stream charger to charge is not always convenience to work. Similarly, some battery chargers have a Startup setting that provides higher current strength. Depending on how much battery power you have, you can even turn on the charger, select the "Start" setting, and start the engine immediately.

The main benefit of buying a plug-in jump starter / battery charger is the charging part of the equation. Although you can get instant startup from the Start settings of some chargers or jumper boxes, it's not so good for your charging system. Because modern alternators are not designed to charge completely dead batteries, forcing them to do so can shorten their useful life. If you have a charger on hand and you can wait for a while to get the job done, you can save an expensive generator repair.

Of course, the main disadvantage of plug-in units is self-evident: they must be inserted. Although some plug-in starter / charger units are actually small and portable, they don't work at all if you can. No place to insert.

If you do decide to buy a plugin, then you will need to look for plugins with the following features:

Multiple charging modes (ie 6V, 12V)
Multiple amperage settings (ie 2/10 / 75A)
Floating charge option
