Charger extra digital DV00DV2817 — multifunctional 4-channel charger with digital display

Multifunctional 4-channel charger extra digital DV00DV2817 is designed to charge and monitor multiple rechargeable batteries simultaneously. The charger supports Ni‑MH, Ni‑Cd and Li‑Ion battery types and can charge cells of different chemistries and capacities at the same time. An integrated digital display shows charging status and capacity indicators; the unit automatically detects defective or reverse‑inserted batteries and signals this by flashing all four capacity indicators.

Advantages

The unit offers completely independent control of every channel, allowing each slot to charge and report status separately. A power‑bank function enables the charger to supply 5 V/1000 mA from installed Li‑Ion cells for charging smartphones or tablets. The device includes reverse‑charging protection and supports worldwide AC input voltage for flexible use.
