Ideally planned for smoke detectors. This cell can however also be ideally used on many devices of Digitech and Boss brands and that is how I tested. No doubt, it largely takes longer than a classic range of another brand with consistency in power delivery. But given the price I am not sure it is economically designed to power large appliances over a period of fast or average time, except for some special cases, of course, where we must ensure that the camera does not flinch before a defined time. In most cases, I think it will be economically viable on small consumer devices but frequent operation or permanent and as such, long-term, however, the high price ensures a consistent power over the life .
