Anker. I have a 3 foot cord in my work truck and 2 in my wife's van. I have two 6 foot cords in the living room and one in the bedroom. Never an issue with fraying, pinching or slow charging. On Amazon it's like $14 for two 6 foot cords.
Correction: $12.99 for 2 in red or gray

I use an anker from Amazon. I got two 6' braided cords and a great adapter with anker's smart charging and fast charge 3.0
I use these on the daily and even leave one in my car. They support fast charging and will assist in recharging my phone by the time I get to work if I forgot to charge it at night (40min). Anker is the only brand I trust now after having spent egregious amounts of money on other branded phone accessories.

This one has been incredible. It's long for the car but there should be options for shorter ones. I just keep it tucked in next to the passenger seat so it isn't sticking out.
