Min. charge current

The smallest current that the device can provide in charge mode. If this parameter is specified in the specifications, this means that this model has the ability to adjust the charge current (otherwise, only the maximum current is indicated).

Charging current is one of the most important parameters for any charger: see “Maximum charge current. And the general range of current adjustment depends on this indicator: the lower the minimum value (with the same maximum) — the more extensive the possibilities for setting up the "charger" for the specific specifics of work.

Charge current (all channels)

The highest current provided by a multi-channel charger (see "Independent channels") at full load, with all slots (and, accordingly, channels) operating. In fact, a guaranteed maximum current provided by a multi-channel charger, regardless of the number of channels involved.

For the total charge current, see “Maximum charge current. Here we note that the full load is a rather complex mode in which the current strength can decrease. Therefore, this parameter is specified separately.

Number of settings

The number of separate charge current settings (see above) provided in the design of the charger. For example, a device with 4 settings may provide options for 200, 400, 800 and 1000 mAh. In general, the larger this number, the more accurately you can choose the charging current for a particular situation.
