| 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. |
