A different take on the compact, hi-tech charger to the similar CTEK. Buttons let you switch between slow and normal charge rates, but annoyingly, to use the right one, you have to compare your battery’s Amp Hour rating to a table on the box. You get decent leads and a hard-wired adaptor, yet the conditioning cycle is basic.
