Compare Nitecore UMS2 and UM2
Charging devices Nitecore UMS2 and Nitecore UM2 have 2 charging slots each and support the same types of batteries, including Ni-Cd, Ni-Mh, and Li-Ion. However, the UMS2 offers a maximum charging current of up to 3000 mA, while the UM2 is limited to 1500 mA. Both devices feature a display for operation indication and protection functions against overcharge and overheating. The UMS2 also supports "Quick Charge" technology version 2.0 and allows manually selecting the charging current and voltage, making it a more versatile option for users who need a high charging speed.

Glossary
Max. charge current
The highest current that the device can provide when charging the battery (or the nominal value of the charging current, if it is not adjustable).
Charging current is one of the most important parameters for any charger: it determines the speed of the process and compatibility with certain batteries. In general, the higher the current, the faster the process, the less time it takes to charge. At the same time, some batteries may have recommendations for the optimal current strength and restrictions on its maximum values. Therefore, mindlessly chasing a powerful charger is not worth it: at first it's ok to clarify how justified such power will be.
Note that in multi-channel devices (see "Independent channels"), the maximum current strength can be achieved when only part of the channels are operating. The indicators provided when all channels are operating simultaneously are indicated separately for such models (see "Charge current (all channels)").

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.
