With the 4in1 charging station, you can charge up to four USB devices simultaneously. The ports support fast charging technologies such as Power Delivery and Qualcomm Quick Charge 3.0, allowing your smartphone, tablet, and power bank to be charged at maximum speed through the outlet. This multi-USB charger with four ports enables the simultaneous charging of four devices, such as a smartphone, tablet, power bank, and another phone. Devices are charged at high speed, reaching 60% in just 30 minutes, which is ideal for newer generation devices, as they often do not include chargers with the purchase.
