QUOTE: "Output: 5V/2.4A, 6.5V~9V/1.5A, 9V~12V/1.2A Max"
注意其中 9V~12V/1.2A MAX
FISHFINDER 要 12V 供电. 才 1.2A? 够您的 FISHFINDER 最多运行一个多小时吧.

20AH 是指在3.6-4.2 伏的状态下, 在12 伏的状态下是 20×3.6/12=6 AH, 加上10- 20%的转换损耗和低温损耗 6×80%=4.8AH, 按理普通 Fishfinder 一天差不多也够了,

有升压线卖,从montreal那边寄出的,但不知道转换率如何,还有安全性是否可靠。不过觉得这类产品做应急用可能还可以,正常使用不知道效果如何。

哦,长姿势了,如果要另外买其他的转换设备,这个不值得投资。

淘宝上也就是卖10加币多一点的东西,这价钱有点小贵,敢打赌也是Made in China的

这个的缺点是Max Output Current: 800mA有点小,我图中的那个cable,Max Output Current: 1200mA。

Thanks Wetnose but can you tell me 800ma still ok? I have a 5 inches fishfinder with chrip and usually I use it around 4 to 5 hours each time, is it still ok for 800ma?
Thanks again!
