Question 1

Can 2 extension cables be connected?

Accepted Answer

Well, NOCO support, I have used the 6 NOCO extensions for several years now and they work fine.  Current is current, no?  If you run an extension cord out to the car the NOCO unit will be there as well, free for the taking.
just sayin.  The product is awesome.  I have 2, the other charges 2 motorcycles in the garage.

Question 2

If the extension is only 3.75 feet long, why is it called a “10 ft extension”?

Accepted Answer

3.75 meters is about 10 feet. Did you try it before you asked?

Question 3

Does it fit the G 40 Booster?

Accepted Answer

No, this product is for select models of our GENIUS Battery Chargers only. Unfortunately, there are no extension cables available for the clamps on the Boost products as extending the cables would reduce the starting power they produce. If your positive and negative posts are too far away from each other, you can also connect the negative clamp to a reachable ground on the vehicle chassis rather than the negative post.

Question 4

Mu genius boost+ gb40 was shipped with a noco gc004 10 ft cable.  it doesen't fit.  why was it sents?

Accepted Answer

I returned the extension cable along with the gb 40. The reason being their customer service rep. could not answer my questions. Concerning an A/C charger which was not included. I ordered a Micro-Start XP-10 through AMAZON which I am VERY happy with.
