For running out of battery!

Today I was nervous because my iPad mini's battery ran out.。Long time, no see。
Recently、I no longer carry around large capacity batteries。I'm refraining from using it because it's heavy with other luggage.。I have included a simple battery.、It doesn't have enough power to charge an iPad mini...

Nine times out of ten, I can use it without any problems.、Like today、It's true that there are days when I don't have enough...。

As a countermeasure、Do you carry around heavy batteries?、Should I give up?。
When traveling by car, there is a way to charge the battery in the car.。If you think twice。

Would you like to do that? ? That one that plugs into the cigarette lighter socket is lightweight.。I don't think it's that expensive。
Let's look for it! !
