Frequently asked questions
Can it deliver 10 A at 30 V?
No. The 300 W rating limits the output power, so the full 10 A is only available at lower voltages. Keep voltage multiplied by current at or below 300 W.
Are the USB ports suitable for charging my phone?
Yes, the two USB quick-charging ports are designed for charging compatible USB devices. They are separate from the main adjustable output terminals.
