If I connect via the extension cord I can tell the pump is not working as strongly.
Now I don't have to worry about whether I can reach the tire or not.
This has to be one of the more handy purchases I have made lately.
With my portable battery, I was able to plug it into the power port on my vehicle for starting and was able to run the vehicle over 30 miles to the repair shop to replace the failing alternator.
It's a cable.
Well it is not trasmitting power from the power bank to the car, so i really dont know why i bought it.
So, maybe my 3-star rating is a little harsh.
On the web page and package, the connector is rated at 50A, which [as an electrical engineer] I can say with confidence is totally ludicrous.
Yet, they say the wire is good for 5.9A max, and the internal fuse is 10A.
It broke off in the socket before I could use it.
