150 Amper*hour is the battery charge capacity. With power of 25 Watt = 25 A*V at V = 12 V you will supply 25/12 Coulomb each second (Amper*s). So the charge time is equal to 150/(25/12) = 72 hours.share | cite | improve this answer.50 Amper*hour is the battery charge capacity.

A long-arm quilting machine. 1  The serger, or overlock, machine is another type of specialty sewing machine. 2  It sews with multiple needles and multiple threads to create stitches better suited to stretchy fabrics, such as those used for t-shirts and swimsuits. 3  It is probably not what you want for general purpose sewing.
A sewing machine is a machine used to stitch fabric and other materials together with thread.
