Opus BT-C3100: user manual, user guide, review

The primary criteria in the choice of digital technology and battery equipment is rightly the functionality, reliability and efficiency in operation. At the same time, as the technologies of autonomous power supply develop, manufacturers of the same mobile devices can not but pay attention to the emergence of new approaches to the organization of charging. Developers tend to make this process as easy as possible, thereby attracting the consumer and according to this criterion. A rather unusual, albeit quite logical attempt to master this direction was taken by the creators of the Opus BT-C3100 charger, the review of which is presented below. In this small device, the concept of universal charging was continued, but new possibilities were added to it.

Device Features

The model is a small device designed to charge batteries and batteries in four slots. Unlike similar devices, this modification allows you to work with a wide range of charge current indicators up to 2000 mA. Especially for working with nickel-cadmium and lithium-ion elements, the device integrates optimal charging characteristics. And both batteries of different types can be serviced in slots at the same time. If high-voltage batteries are used, a special switchover on the control board is required from the user himself. Also, the features that distinguish the charger Opus BT-C3100 from the total mass of analogs include the extensive inclusion of protective systems. The most effective among them is the possibility of detecting overheating and preventing the negative consequences of a short circuit.

Main characteristics

One of the main parameters is the charging current range. It has already been noted that the maximum is 2000 mA, and the minimum is at 200 mA. In this case, the current unloading, which is effective only for lithium-ion batteries, is in the range of 200-1000 mA. The maximum charging capacity is 20 000 mAh, which is one of the best indicators in the class. At the same time the device has very modest dimensions - 14.4x9.8x4 cm with a mass of 0.234 kg. As for the case, the device Opus BT-C3100 is made mainly of plastic, but provided with modern insulation coatings. The model includes only the power adapter and operating manual.

User's manual

During the use of the device, the owner will have to deal with the LCD display, which will reflect the performance of the device. The display shows several display panels, each of which corresponds to a separate mode of operation. The MODE button is responsible for selecting the mode. To activate the desired format of the device, it is necessary to hold it for several seconds. You can monitor the parameters of the serviced items through the DISPLAY panel. In particular, it reflects the current values, voltage, battery fluid characteristics, etc. The charge current control element is separately presented - the CURRENT button answers this choice. To indicate a specific slot, the SLOT button located at the edge of the Opus BT-C3100 is the active control button. The instruction notes that a command with charging parameters can be given to each cell separately, and to all placed batteries at once.

Maintenance Instructions

The device requires careful attitude, maximum protection against strong impacts, chemical damage and exposure to moisture. It is important to take into account that even high-quality intellectual charges may lose their working qualities with time. It can appear, for example, in the deviations of the recorded indicators when analyzing the next battery. The best accuracy in the family shows the modification of the Opus BT-C3100 v 2.2. The instruction also recommends testing it for all operating parameters. For testing, it is also desirable to use high-level equipment with a minimum error. In addition, it is recommended that the connectors be cleaned periodically with special material. It is impossible to allow salting of functional surfaces, since such phenomena primarily affect the loss of accuracy of electrochemical measurements. In addition, the optimum battery charge time should be respected. Track them the same control panel with a display. Exposure to these standards is useful from the security point of view both for the device itself and for the batteries.

Positive feedback about the model

The device has a lot of advantages, which are not overshadowed by the rapid wear of the working base. Users on the foreground in this list derive the omnivorousness of the device. He works with elements of various kinds, both popular formats, and little-known. And separately indicates the ability of the device to additional extended measurements with the same lithium-ion models. The competition in the efficiency of servicing this element can only be made up of specialized equipment. There are other advantages that attract the new generation of Opus BT-C3100 v 2.2. The reviews indicate that even slightly damaged and damaged batteries can be serviced by the device - the main thing is that the body of the element is integral. Praise users and the implementation of the control panel. In general, the presence of a functional operator display is a rarity for chargers, but in this case, the introduction of innovation was successful.

Negative feedback

Among the significant flaws users give out unless the lack of support for the format of telephone batteries. Because of this shortcoming, the model, of course, can not be considered fully universal, although it is possible to get out of this situation by applying special adapters. To minor drawbacks, users attribute a relatively low update rate, periodic inaccuracies in measuring mAh, as well as overheating of the case. It should be noted that many consider the cooler as the weakest place of the Opus BT-C3100. Reviews, however, note that in the new versions of the device the cooling system has been substantially redesigned and improved. It's another matter that this was not reflected in the errors in measurements by some indicators. The range of deviations of 3-5% still remains an unpleasant operational moment of this model.

How much does the Opus BT-C3100 cost?

In the domestic market, the model is available for 1.8-2 thousand rubles. This is a relatively small amount, if we take into account the qualitative element base of the device and the functional that it offers. If you want, you can find a more affordable price similar to the Chinese device with an extensive list of performance indicators, but such products will be much inferior both in terms of measurements and in durability. If we compare the Opus BT-C3100 with its counterparts from the major brands Liitokala, La Crosse or Fujitsu, then its cost advantage will be insignificant. With this product, you still need to compare primarily with respect to performance.

Conclusion

The device is unlikely to be useful to an ordinary user of equipment, working on batteries. Today, typical device models are optimally supplied with energy from simpler universal charges. The wide functionality of the Opus BT-C3100 in such cases can be left unclaimed. Such a purchase will justify itself, rather, in the hands of specialists or fans of radio engineering, who actively use batteries of different formats. An important feature of the development from Opus is a wide range of parameters that the device captures when analyzing the filling of the serviced element. That is, in some ways it is not even so much a charger as a diagnostic tool. This is evidenced by the external panel, rich in optional features and controls. The manufacturer has thought out both balanced technical and operational qualities of the device, and its ergonomics, which is significantly improved in new modifications.
