The good news is that it is directly compatible to at least some non-Foodsaver brand vacuum pumps.
My sealer/pump was a cheapy, either from Lidl or Aldi. The brand is Finether. Like this one...

I just received my FoodSaver branded hose and Jar adaptors from US amazon, not expecting the hose to be compatible.
But it fits and works perfectly. Vacuum seals a jar in about 30 Seconds.
It's also compatible with the 4 quid brake bleeder off amazon UK. With that it took about 90 seconds of fairly hard pumping to seal a half empty jar. Harder work, but successful.
My battery pump from Poundstretchers (£5.99) was a dead loss.
