Frequently Asked Questions

 Q: Which devices can the Rockpals 300w power?
A: Please note that the AC output port can only charge/power the device with power below 300 watts; once exceeded, the Rockpals 300w will automatically shut down. Please refer to your device specifications before purchasing.
Q: How do you know the working time of your equipment?
A: AC working time = 280Wh * 0.85 / working power of the device and DC/USB working time = 280Wh * 0.96 / working power of the device. For example, assuming your device consumes 30W (possibly a 40-inch TV), the AC working time is 280wh * 0.85 / 30w = 7.9 hours (rough calculation); DC/USB working time = 280Wh * 0.96 /30w = 9.0 hours (rough calculation).

This is a Dope product! I took this ‘BIG MAN’ for camping last week, and I dropped this power station on my way to the destination (Sorry). However, I am super surprised that this power station can still be used without any problem. Good quality! I like it.

We hosted a birthday party using this generator. It's versatile, we was able to used it to power up the electrical inflator for the air balloons and mini refrigerator to keep the drinks and cake cold. It can also be use to charger an outdoor speaker for music playing. One station for all the purposes.

I purchased this for remote CPAP use, and it truly works effectively for that purpose. Very handy cigarette lighter plug along with numerous other DC and AC plugs.
