Rockpals 250-Watt Portable Generator Rechargeable Lithium Battery Pack


Q: What devices can ROCKPALS 250W power?

A: Please note that the AC output port can charge devices less than 250W, DC output can charge devices less than 60W; Once exceeding, the RP 250W will be in protection mode. We need to charge it by wall charger to reset it.

Q: How to calculate the working time for your devices?

A: 1. AC output working time=240wh * 0.85/the power of your device

For example, assume your power of device is 50W, working time will be 240wh * 0.85/50w=4.08 hrs ( rough calculated )

2. DC and USB output working time=240wh * 0.95/the power of your device

Q: Can it support pass through charging?

A: No, our 250W portable power station cant support pass through charging. We recommend to use 300W portable power station.
