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.
With thousands of threads to choose from, we want to make the process as simple as possible. Simply pick the brand you love and the thread type you need. It's as simple as that. Whether you need Serger (Overlock) Thread, Decorative Embroidery Thread, or everyday General Purpose Thread, we have what you're looking for plus much more!
