I own this troubleshooting group if power cut. Average quality (made in china, it is found in several brands, EINHELL, mxpower, but it's the same basis) and as long as you let manipuliez heat and carefully (do not pull on the starter wildly up to the stop, etc ..), the machine works properly and does the job, but consuming little loudly. (Mine turns rounder in only 98 SP 95) the -: noisy -Fort - Limited power (good for lighting or low power devices) the +: - Starts from the hip - Ok for a fridge or a jig-saw -autonomy 5 to 6 hours
