Can we recharge the bottle with a bike pump?
No, a bike pump is capable of only reaching pressure from 15 to 20 bar maximum. Our special manual pump is capable of reaching more than 200 bar of pressure. Its special (patented) design allows it to be robust and recharge the bottle without any physical difficulty.
You will also be able to make several refiles for sharpen by respecting the cooling time every 3 minutes.
