Silicon Power QS28 20000
 | Outdated Product £43.82 A practical and inexpensive model with a case thickness of 28 mm and a weight of just over 400 g for charging up to three mobile devices overnight. A power bank from Silicon Power will come in handy when away from electrical civilization, during power outages, while traveling and on long trips. On average, a smartphone can be charged 3 to 5 full times. The model accumulates energy reserves in a lithium-polymer battery with a “passport” capacity of 20,000 mAh, but in reality it is capable of transferring up to 12,600 mAh capacity to connected gadgets. This spread is due to the fact that the capacity is stated for the battery supply voltage at 3.7 V, while the output voltage of the USB bus is already 5 V. Silicon Power QS28 20000 has one USB type C port of a double-sided design, which provid...es 18 W of charging power using the Power Delivery protocol. And through the USB A connectors, devices are quickly charged according to the Qualcomm Quick Charge 3.0 standard (with the same 18 W output power). An additional input interface in the model's arsenal is represented by a microUSB port. The complete procedure for replenishing energy reserves in the battery cells of a power bank takes about 6.5 hours. The portable battery is equipped with a small information screen - it is used to display the percentage of battery charge remaining. |
