But if the battery wants to charge with more current than the adapter can handle, the adapter might overload. If it's a good adapter it will just switch off. If it's a crappy one it might catch fire. So your choice.
Electrical Engineering Stack Exchange What if i charge a battery with low ampere.? Assuming we have a mobile-phone LiIon battery and a charger which is only able to supply less ampere than the original one, will it damage the battery if i charge with less ampere charger than the original one.
The only way a low charging current might contribute to a reduced life is in the hands of an inexperienced designer who thinks that lithium cells behave like nickel or lead, and that if the current is low enough, then a gentle overcharge is permissible. With lithiums, no overcharge is ever permissible, see the second paragraph.
Most automotive batteries recommend a charging current of between 10% to 20% of their capacity. For instance, a 60 Ah battery typically charges at 6 to 12 A. Adhering to these rates prevents overheating and extends battery lifespan. Monitoring battery temperature during charging helps prevent overheating.
