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.
Sewing tables are an individual preference. What works for one person might not work for another, and itâs largely dependent on your height. Ideally, you will have two sewing tables: one set up for using your sewing machine and another set up for cutting fabric.. Find a sewing table that best suits your height. Since everyoneâs elbow height is a bit different, itâs a great idea to have your sewing tables custom-made. This is especially true if you are particularly tall or short. If thatâs not an option, see whatâs available at your nearest craft store.
