Centurion Regulator for solar backup

Lets start by adding this might not be a cheap chinese product, hence the price. it is a tested and thoroughly thought through plain and simple regulator, works on solar panel that I bought at 18v 80W and churns out power as a backup to the battery in the centurion gate motor. you know you need a backup on a backup these days :)

Then the supplier is efficient, communication at each point of the purchase steps, making my experience a breeze. Product bubble wrapped and boxed up with a speedy delivery and supporting invoice. Appreciate it!

Stylish and Great Value

The Black Bamboo Tumbler has a clean, modern look that suits most contemporary bathrooms. The matte black finish pairs nicely with the natural bamboo base, giving it a stylish, minimalist appearance. It’s lightweight and works well as a toothbrush holder or rinsing cup.

Perfect product exactly as advertised.

Perfect product, it fit perfectly into to my cz75 p07 CO2 pistol and this setup even turned my non Blowback into a Blowback pistol. It will work on the ASG STI duty one aswell as they use the same internal.
