Do good volt converterrequire a lifetime warranty?

The recommended warranty period depends on how often you use your volt converter, how expensive is it, what company made it, and many other factors. Manufacturers sell their most expensive products with a lifetime warranty, while the least expensive volt convertermight be not guaranteed at all. We think that the best warranty period for a good volt converter is five years.
