4G modems tend to need a lot of oomph from the power supply. I'm not sure how much this port offers but standard USB 5V x 0.5A (2.5W) is not going to cut it. TX

4G modems tend to need a lot of oomph from the power supply. I'm not sure how much this port offers but standard USB 5V x 0.5A (2.5W) is not going to cut it. TX power alone can go up to 2W and that doesn't include processing, losses etc.
