Modern power bank - REMAX Linion RPP-124. The high-quality lithium-polymer cells provides a capacity of up to 10,000 mAh, which allows you to quickly charge the device. Made of high quality components - ABS + PC, guarantees resistance to damage and long-term use. High capacity (10,000 mAh) allows you to charge devices multiple times. Compact size means that the product fits even in your pocket and lets you carry it with you. Has two USB outputs, enabling up to two devices to be charged simultaneously. Built-in LED indicator shows the current capacity. Smart Chip helps control current and voltage, ensuring stable power. Specification: Materials: ABS PC Capacity: 10,000 mah Battery: Polymer Input: DC5V-2A Output: DC5V-2.1A USB * 2 Micro * 1 NOTE! Nominal capacity expressed in mAh (milliampere hours) means the sum of all cells that were used in the power bank. The cells used have a voltage of 3.6 - 3.7V, while the standard USB port - 5V, so voltage conversion is necessary, which in turn translates into real capacity. After conversion, it is usually around 65-67% of the original value. This means that for a power bank with a capacity of 12,000 mAh, in fact about 8,000 mAh is available.
