Frequently Asked Questions

Can it charge four batteries at once?

Yes. The D4S has four independent charging slots and can charge up to four compatible rechargeable batteries simultaneously.

Can it charge Li-ion and Ni-MH batteries together?

Yes. Each slot is independently controlled, so compatible Li-ion, Ni-MH, and Ni-Cd rechargeable batteries can be charged in mixed setups.

Is it better than a 2-slot charger?

For users with multiple torches or spare batteries, the D4S is better suited to higher-volume charging because it can manage up to four cells at once.
