How many amps do I need?

Reviewer consensus

For maintaining a motorcycle, ATV, or seasonally stored car, 1–2A is plenty. For routine car charging in a reasonable timeframe, 5A is the practical sweet spot. Choose 10A or higher only if you regularly recharge deeply discharged or large batteries and want faster turnaround.
