오래전에 아답터 질문해 놓고, 오늘에서야 구입하러 용산을 갔는데, 7v는 어디서든 안팔더군요ㅠㅠ

그래서 구글링을 하다보니까 이런게 나왔어요

왠지 충전기가 마이크로5핀이라는 점이 그렇긴 한데, 저 사진대로라면 5v 충전도 가능할까요? 

아마존에서 어느 유저가 이런 걸 섰는데, 한번 올려볼게요

The Bad: Only comes with a very small selection of common bits. It will charge with other USB devices, but keep in mind most USB chargers are 5V/1A, and so using anything but the DC adapter will slow things waaaay down. There is no chuck, so you /have/ to use standard-size bits, and aside from giving it 'a little' to 'a lot' of juice, there's no clear dial for changing torque.
