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 youâve got zigzag stitch on your regular sewing machine, you can use that instead. In fact, the instructions in the Coco sewing pattern and Agnes sewing pattern assume you are using a regular machine (but if you are lucky enough to have an overlocker or serger, go ahead and use it if you prefer!).se a ballpoint or stretch needle in your sewing machine. Personally I find ballpoint needles work well for me-they have a slightly rounded tip which passes through the looped structure of the material without laddering it.
