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.

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.

Drip charge

Ability to operate the device in drip charge mode.

Drip charging is called charging a battery at low currents — on the order of several tens of milliamps — used to compensate for self-discharge ("volatilization" of accumulated energy over time). This function is relevant mainly for Ni-Cd and Ni-Mh batteries, which have quite significant self-discharge rates: it allows you to constantly keep them fully charged. This is especially useful in cases where the battery may be needed at any time (but it is not known exactly when).

In box

In addition to the main charger, the package may include batteries, cigarette lighter adapter, adapter to another type of battery and bag (case). More about them:

- Battery. Some modern chargers can be equipped with batteries - of course, the latter are best suited for this model. Buying such a kit is often more convenient than buying a "charger" and batteries separately (at least it's faster).

— Cigarette lighter adapter 12 V. Presence of a charger adapter for connection to a car cigarette lighter socket. For more information about this connection, see "Charging from the cigarette lighter"; here we note that not all models with the possibility of such charging are initially equipped with auto adapters. Therefore, if it is important for you to be able to connect the charger to the cigarette lighter out of the box, you should pay attention to the models in the appropriate configuration.

- Battery adapters. Such adapters allow you to use the charger with batteries of "non-native" sizes (see above), and, as a rule, larger than standard ones. For example, a model for AA and AAA batteries can be equipped with adapters for C or even D. This is more convenient than using a charger that was originally designed for large sizes: the device turns out to be more compact, and if necessary, a large battery is connected...without problems through an adapter.

- Storage bag. The bag plays the role of a protective cover and can be used not only for storage, but also for transporting the charger. At the same time, it often provides additional compartments for various items - both complete, such as an external power supply, and additional, such as batteries. Therefore, and also because it fits optimally in size, a complete storage bag is much more convenient than impromptu cases.

Mains plug on cable

Chargers with a plug for connecting to a socket on the tip of the mains cable. Models with a plug on the wire provide freedom of placement of the “charger” (especially in cramped free space near the outlet). So that the cable does not get tangled at hand, in many models it is made removable, which makes it easy to store the charger.
