Qc 3.0 wall charger
The battery capacity of smart phones is getting bigger and bigger. In addition to the power saving capability, the charging speed has become a feature that users are paying more and more attention to. Qualcomm's Quick Charge technology has become one of the best examples in the industry. Following the Quick Charge 2.0 specification, the latest Quick Charge 3.0 technology (QC3.0 for short), the average mobile phone only needs to charge for about 35 minutes.

The mobile power solution can simultaneously output two sets of power supplies, one set is QC3.0 output, and the other set is fixed 5V output, which can charge two mobile phones at the same time. The QC3.0 output has a maximum power of 18W, a minimum output voltage range of 3.6V, and a maximum of 12V. The fixed 5V output has a maximum power of 10W.
In addition to the general 5V adapter for mobile power input, the biggest feature is to support QC3.0 adapter, so that the mobile power battery itself also has a fast charge function, the maximum charging current is up to 4.5A, and the mobile power can be charged up to 80% in half an hour. Electricity.
