Comments Look elsewhere. Look elsewhere. A great charger. 4 individual charging channels. User selectable rapid or slow charging. Optional car charging kit. The Doc's choice. Better value elsewhere. Unsatisfactory rating on instructions because they do not even tell you what the LED means! Better value elsewhere. Poor build quality and some design faults. It has the potential to be a great charger if these issues are addressed. A superb charger. Individual cell charging, fast, packed with safety features, able to condition Ni-Cd & Ni-MH batteries. Great value for money. The Doc’s performance choice.
