我经常caming时用电动充气泵给气垫床充气，车打着火，用车的电源插座输出，有时持续十几分钟，这样对电池是否有损害，还是发动机启动时用的电不经过电池？
Starter转一次耗的电发动机要run 20分钟才能补回来，你自个儿算算去那个省电池。
所以不管发动机是否启动着，车上插座输出电都是从电池储存的电量？如果我不开发动机，怕十几分钟充气后把电池的电用的太多车发动不了。
启动和idle根本就是两回事。
用的电不是持续从电池储藏的电来的，否则电池经常充放大量电会缩短寿命。按你这么说，idle时用的电是从发电机来的我就放心了。

包括给轮胎打气都搞定了。
要经常充电，否则过段时间就死翘翘了。我有个jump starter 好长时间没用就充不进电了，现在买了个小的air compressor挺好，不用充电
comes from your alternator. You may not need to run your engine at all depending on size of your pump.

几个气垫床体积都不小，还是engine idle保险
more than 10 amps. So, if you run your pump for 15 minutes, it consumes about 2.5 AH electricity. That is about 2% of a typical SLA battery in cars.
6.25 amp. It won't affect starting of your car unless your battery is already dying.
which runs at 10 amps max. I ran it for about 5 minutes. That is equivalent to 8 minutes run-time of your mattress inflator. Use a few percentage of your battery capacity is not a big deal. It is all about one's anxiety.
