[Expired]Tire Inflator Portable Air Compressor

: Car tires are 28-33 PSI. It claims to fill 21 tires, but who knows how many it can actually do 汽车轮胎28-33PSI看说能充21个，实际不知道能充多少

: Gas stations might not always be close, and tire pressure could be low at any time... Car owners can face all sorts of situations. For example, if we return to the US after being back in Mainland China for a while, and want to drive to the supermarket immediately, a jump starter and tire inflator would definitely come in handy. 加油站不一定近，胎压随时可能不够...车主什么情况都有的，比如我们回国一段时间再回来，想马上开车去超市搭电宝充气宝就都用上了

回复 @匿名用户 : Just go get some gas, even $10 worth, then show the receipt and say you need air. Some gas stations are stingy about it. 你去随便加点油, 10每分也行, 然后给他看收据, 说我要打气就行, 加油站有些比较小气

回复 @我是不是也该换个名字 : A bicycle pump can also be used to inflate car tires in an emergency, though it's very inefficient. 打气筒应急时同样可以打汽车轮胎，只是效率很低

回复 @匿名用户 : ...A manual pump for car tires??? By slow I mean it just takes a few minutes, and since it vibrates during inflation, sometimes the air valve is on top, so the inflator can't sit on the ground and you have to hold it the whole time. ……打气筒打汽车轮胎？？？我说的慢也就是几分钟，因为充气的时候在震动而且有时候充气口在上面充气泵不能着地只能守着。

: Not bad, takes about 10+ minutes to fill a tire. 还行，给轮胎充十几分钟差不多

: Pretty efficient with 70% performance for a 12V air pump. You have to choose between portability and battery life. 算是挺高效了 70%效能 12v气泵式, 便携和电池只能二选一

回复 @匿名用户 : Is there another model? I clicked in and saw that this one is also cordless, plus there's a promotion. 是还有另一款么，我也是点进去看说这款是Cordless的，还有优惠

: It is on sale! There's a coupon on the page, and you need to use a discount code at checkout. 打折啊，页面有coupon，结账要用折扣码

: Enter it in the promo code field during checkout. 在结账的那一步输入在promo code那一栏

回复 @西雅图博越旅游包车接送机定制游 : I think it works quite well—definitely worth the price, go for it! 我觉得挺好用的，这个价格可以冲

回复 @zhuozhuobest : Got it, thanks! 好的，谢谢！

: Is it the 12V socket? 是哪个 12V 插座么?

回复 @KellySoon : Plugs into the car's cigarette lighter 插车子点烟头

: Not sure what Amazon was thinking setting that original price, usually it's just something to look at 不知道Amazon这原价定的是咋想的，一般就是看看就好
