ROCKPALS 300W Portable Generator Lithium Portable Power Station



Q: What devices can ROCKPALS 300W power?

A: Please note that the AC output port can charge devices less than 330W, DC1 output can charge devices less than 96W, DC2 output can charge devices less than 48W. Once exceeding, the RP 300W 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=280wh * 0.85/the power of your device

For example, assume your power of device is 50W, working time will be 280wh * 0.85/50w=4.76 hrs ( rough calculated )

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

Q: Can it power to cpap?

A: Of course, it can. RP 300W power station can power your cpap by two ways: 110V AC plug and 12V/24V DC plug. We strongly recommend to use ROCKPALS DC converter ( sold separately by ROCKPALS ) with this power station and turn off the heater and humidifier to get about 3+ nights use.

Q: Will it be shut down once charging low watt device?

A: Yes it will. However, for this issue, we update it. It will be shut down after 10 hours once you dont use it or you charge the low watt device is less than 1W for AC port, less than 1.68W for 24V DC port, less than 1.2W for 12V DC port, less than 0.25W for 5V USB. This function can save the power and prelong the life of portable power station.

A: Yes, it can, if do a UPS, the input is 78W, the output only be 78W or less than 78W can be power constantly
