Am satisfied with the device. That although the jumpstart for cars have not tried, but the other such. B. 230V socket, USB, etc. compressor function. One is questionable for me and although in the description mentioned by the seller the GEL battery in the Power Station? In the accompanying description, but there is talk only of a lead / acid battery. But I guess this Global Power station on the basis of previous findings from good to very good. PRICE => Performance is fine.
