Optimal charging for Galaxy Note smartphones

The Samsung EB-P3300 external battery differs from its analogues not only in the presentable appearance of the case, made of durable dark grey anodized aluminium, but also in its outstanding charging characteristics. The model is designed to be compatible with gadgets from different manufacturers and, in addition to Samsung's own proprietary standard Adaptive Fast Charging, which allows you to correctly charge new generation Galaxy Note smartphones, it supports Huawei SCP, Qualcomm Quick Charge 2.0 / 3.0 and Power Delivery 3.0 protocols.

Support 25W multi-channel charging

At the top of the portable charger there is a plastic insert with a power button, 4 LED indicators and 2 ports: a universal In / Out USB Type-C and a USB A output jack. Both ports are high-speed, they can be used to replenish the battery capacity and charge external gadgets with power of 25 W, and the maximum distribution potential for 2 lines is 18 W. The controversial solution of this UMB is a non-obvious charge level indication system, which differs from the generally accepted one. So, with 1 burning LED, 5 – 20% of the capacity is assumed, with 2 – 20 – 40%, 3 – 40 – 70% and 4 – 70 – 100%. It is difficult to get used to such a gradation, especially for users who have previously dealt with power banks from other manufacturers.

Universal USB-C cable included

With a claimed battery capacity of 10,000 mAh, its actual value does not exceed 6400 mAh when charging at 5 V / 2 A. It is clear that fast charging with a current of 3 A will further affect the decrease in battery capacity. Apparently, in this model, the main emphasis is not on the energy reserve in the battery, but on a high charging speed. The device comes with a flat cord with 2 USB Type-C connectors 20 cm long, the use of which helps to reduce charging losses. A similar Samsung EB-U3300 model with a built-in induction charging module and 2 USB type-C ports will cost 1.5 times more. At the same time, it is up to you to decide whether it is worth paying extra for the 7.5 W wireless power replenishment power and a USB-C port instead of USB A.
