Hand held sewing machines are the mini sewing tools small enough to hold in your hands while stitching. Most are made for on-the-spot repairs of denim, wool, leather, silk, and other small hobby crafts.
Most handheld machines are cordless - thus they make great replacements for manual stitching. The compact size and light weight are what make these portable hand sewing tools perfect for use when traveling, in RV or family vacations.
However, handheld sewing machines are not sufficient enough for professional projects that require more than just the basic stitch work.
There are hand powered and battery models, and they are both equally inexpensive. The manually powered - hand crank sewing machine quite often tends to create sloppy stitches, while the electric rechargeable or battery powered versions can often accomplish stronger, tighter, and more consistent stitches.
Either choice is better than performing hand-stitching, which can become tiring and hard on the fingers and may quite possibly produce sloppy stitches as well.
If you are looking for a light and portable device that can be used under emergency situations such as when you tear your pants, then it would be a great idea to buy a cordless hand sewing machine. The good thing is that:

Final Recommendation:
The mini hand held sewing machine is an inexpensive substitute for manual labor, but receives mostly negative reviews. It does not require as much maintenance as the standard sized devices, but if the product does not work, why buy it? Among the many models that are available, the Singer Stitch Sew Quick seems to sell the best. As with any item that you are considering buying, research it thoroughly and, if at all possible, test it before you buy it.
