There's nothing fancy about this cord, it's literally just 4 feet of wire with male plugs on each end. The solder connection look good inside, but the housing almost comes apart at the nose when not in a socket. When I got it the cost was 1/2 as much as another, so if you want something cheap and simple this seems better (and it has no LEDs or such that give even a tiny drain if you want to leave it connecting 2 batteries for a long time). But it also came with no instructions, so although you may think "You just plug it in don't you?", there are some things you need to think about and beware of that I'll pass along.
First, any power cord with male plugs on both ends has the possibility of one end being plugged into a source (like your car) and the other touching something metal (like a body part of the car) creating a "short circuit" which can start an electrical fire (unless a fuse saves you). So although the 12V won't zap you if you touch the bare end, just remember if you pull the plug on one end, always instantly pull the plug on the other end (don't ever leave just one end connected).
I thought they may have a resistor or such inside this to limit current flow thru it as power goes from your car to a "jump start" battery (which is it's advertized purpose), but it doesn't. Although some may think "That's good so you get the full car power faster to recharge it, right?", the truth is this also can create an electrical fire or blow the car fuse from the high power draw and small wires in this. That becomes a real problem if a battery is heavily drained (see my added comment) or if someone tries to use this to "jumpstart" from car-to-car. I did try this to recharge a "jump start" battery in my car after I'd drained it at least 50% and after 10+ minutes of recharging I pulled the plug finding the positive terminal was pretty warm. Nothing came apart or such, but any wires or connections getting warm isn't a good sign. So it works, but you do need to be careful.

Product has dual strong side springs and strong male end contact springs. Will not vibrate loose from use with an air compressor or vibrating tool. 48" long heavy duty electric cord. I am completely satisfied with the product, in fact it's a steal at its price. I'm highly pleased with the product and couldn't ask for more.

Honest reviews on SOLAR ESA1 12V Male to Male Outlet Charger Cord
We needed this to recharge battery for cpap machine on camping trips. Most campgrounds we stay at don't have electric, so after a few days we need to recharge the cpap battery in the car. This allows us to do so.

I have a solar power charger that has a 12v out and I needed to pair it with a battery pack that accepts a 12v male connection. This product serves the purpose. Couldn't find it in Canada.
Cord length, nice and long, about 6ft if I remember correctly. Price was very reasonable. Good buy!
