I did 4 full clips on ponies last year with them, and this year only did the one as battery is too weak now to keep the blades going, have to keep them plugged in now.
Great little clippers if you just have the one I think.
I managed to clip my horse out fully with them last year. They aren't as powerful as my Heinegers though but I wanted a cordless pair for my clipper phobic horse - they are also very quiet.
