FAQS 4

What is the maximum power output of a USB cable?

SPR: The SPR is based on the USB PD3.0 standard with a maximum power output of 100W. Available fixed voltage levels are 5V, 9V, 15V, and 20V, with current ratings of 3A or 5A. For example, at 20V, 5A, the upper power limit of 100W can be reached. EPR: The latest USB PD3.1 standard extends the maximum power output from 100W to 240W.

How many watts can a portable power station Power?

Portable power stations have maximum output limits (measured in watts), determining the devices they can support. For example, ALLPOWERS R600 has a maximum of 600 watts output, so you can easily power laptops, drones, etc. ALLPOWERS R2500 has 2500W output, which is much more than R600, you can even power up an electric drill.

How many watts can a USB cable carry?

And while standard USB Type-C ® cable carries up to 3A current, USB Type-C cable which supports 100W power delivery or EPR is allowed to carry up to 5A, —it means the maximum power is 240W. 1 Checkmark indicates that the current varies according to the PD Power. Current value (A) calculated by PD power/target voltage. Maximum value is 3A.
