Bluetti brand D/C automobile car charger to XT60

Hi, I went and got the bluetti brand dc car charger from Amazon here:

https://www.amazon.com/gp/aw/d/B0CMM2GM1R?psc=1&ref=ppx_pop_mob_b_asin_title

it arrived in the mail and while it is shorter than I would prefer, I still went with it cause of reason is, Is because it’s bluetti brand, not some unknown brand.

the downside is now if want to charge the bluetti elite 200 v2, I now have to move it to the front of the vehicle instead of using a longer cord.

there is this product:

which is longer but an unknown brand. I didn’t want to take a chance of it being poor quality so I decided to play it safe with the shorter bluetti brand car charger. Thoughts?

Also, my vehicle, the car charger ports are on all the time, do should I only attempt to charge it with the car when the vehicle is on? not while it is turned off cause that would drain the automotive starting battery?

The third-party extension cable you linked is usable, or you could also purchase an additional car charging extension cable.

BLUETTI power stations have under-voltage protection, so they won’t charge if the battery voltage is too low. However, if the car engine is off and the car battery is depleted, the charging power might be very low or even unavailable.

where would you reccommend a good brand of car charging extension cable?
