These units have about 2 to 3 hours running time from new. They were packed for a move and 14 years later (now) dug out of a closet box. They both work but the belts will need replacing. The carry case holds both and I would prefer to sell both units together with the case. Both are in excellent condition. Email, call or text. Call 250-743-7491 Text 250-945-5335
