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.
If you are a beginner in embroidery, you do not need a complicated embroidery machine to start with. Cheaper models, with less functions are better for novices. If you are looking for cheap embroidery machine, they are some inexpensive sewing machines with decorative stitches on the market.
