发帖数: 10288 | 1 你读一下它附带的 manual 就知道，这东西最大输出才 15A 左右（fuse capacity)，
指望它给完全无电的电池 jump start 起来是不可能的，但是对于在临界状态的电池，
能推一把屁股
你可以用充电器给车上的电池充电，充到一定程度后在加上那个东西推屁股，看看
能否起来。 |

发帖数: 10288 | 2 买个 SSC-1000A 之类吧。我以前买了一个，从前进汽配买的，用了 coupon 后才
30块左右，不过如果电池真的不行了也是没用的。
如果电池仅仅是因为过放电导致电量不足，充电器可以解决。
电池真的不行了，还是需要 jump start 的。 |

发帖数: 10288 | 3 估计当时要靠自己解决的话，大概是应该用 SSC-1000A 10A 给那个 deep cycle
marine battery 充电30分钟，然后吭哧吭哧地把大电池抱下去，再去 jump start
应该可以成功。 |

发帖数: 10288 | 6 我有两个，Walmart 买的 clearance，根据标称，最大可以达到 400A，重量大概只有
1 lb 左右（不含 cable)。不过这东西我不敢放在车上，德州太热了，锂电池到时
炸了可麻烦了。
有人测试过，好像小车确实没有问题。
从参数看，里面大概是三个 18650 电池，（标称 12000 mAH，大概是三节电池，每节
4000 mAH，合起来就算 12000了，另外电压是 11.1 v=3.7×3）
确实很轻便，带有110v 充电器还有车充，但是夏天我不敢放在车里面。车里面我只放

This thing is amazing. My F150 with the big v8 (the normal battery for it
has 650 Cold cranking amps) was so dead that the power locks did not work,
and none of the interior lights would come on when I opened the door. I
hooked this up, and seconds later I was able to start the truck. It even
sounded the same as it does when the fully charged battery is used to start
it. (ie it did not seem to struggle at all.) It is cr... 阅读全帖 |

电池的时候，做足安全措施，至少戴上防护眼镜。
我就碰到过一次。车电池 fail 了，用 10A 充电半小时后还是启动不了，在
前进汽配网上订了电池，打电话给保险要了服务，拖车来了，用便携的 jump
starter 启动了，然后开到前进汽配，停车，关掉，然后想再试一下电池究竟
如何，一打火，听到车里面爆了一声，车也没有启动，打开引擎盖，发现蓄电池
有一格的盖子冲开了！有些酸液也溅出来了。
前进汽配的员工给我换了电池，然后我简单清洁了一下酸液，打火，成功，走人。
回头再仔细清理了溅出酸液的地方。 |

死的车肯定没问题。电池死到底，完全充不上电，提供不了任何电流的车是另一回事。
prius也是类似情况。
jump电池彻底死的车，好车的电池加发电机需要提供坏车starter需要的全部电流外加
坏电池本身消耗的电流，电动和混动车的12伏电池CCA都太低，比较困难。 |

发帖数: 2406 | 22 我也是从前面关于这个问题讨论里的回复得到的启发
给定的是一个整数数组A 假设长度是n
我们可以构造这样一个directed graph
vertex是v[0], v[1], ..., v[n-1]
edge是如果我们从v[i]出发到v[i+1],v[i+2],...,v[i+A[i]]都有1个edge
那么jump game 1就是寻找有没有从v[0]到v[n-1]的一条路径
jump game 2就是寻找最短从v[0]到v[n-1]的路径
两个题目都是O(n)的时间 因为我们的edge数目是小于c*n,这里c是数组A里面的最大数字
用bfs 我们的时间就是O(n)了
不知道这个讨论对不对
请大牛们指正啊 |

？实在是个新手。
greedy algorithm:
starting at position i, jumping step j, the size of jump j is the one that
achieves max reach from step j-1 to step j.
Proof:
(1) step j is also the max reach from step 0 to step j.
(2) if there exists another strategy that results in fewer total steps, then
there must exist a step (step K1) that covers entirely a step (step K2) in
the greedy strategy. Namely, step K1's start <=step K2's start && step K1's

奇心起去测了一下，第一次不知道那里出了差错，居然给了我一个31.4 inches的数据
，极度不可能，都有80厘米了。
再测了5，6次，果然极其稳定的在24-25 inches之间，哈哈，比较符合。大概60cm出头
，估计不打篮球不骑自行车能多个2 inches
数据统计老美10%的人能 vertical jump 34 inches之上，
